4. FINANCIAL AND TRADING PROSPECTS OF THE GROUP
Below is an extract from the annual report of the Company for the year ended 31 March 2020.
The Group has been actively proceeding with the Optimization and Upgrading Plan since 2011 in relation to the New Mining Right of the Enlarged Kaiyuan Mine. The acquisition of the New Mining Right of the Enlarged Kaiyuan Mine in December 2019 has substantially enlarged the Group's coal resources and will allow the Group to increase the annual production volume to a range of 0.9 million tonnes to 1.2 million tonnes, ten times or more of the existing production capacity of Kaiyuan Mine. The Directors consider that the transaction is in line with the Group's strategy to expand the coal mining business of the Group.
In the coming year, there will be a reasonable expected amount of expenditure in capital assets, in particular for the new plants and machines for the environmental protection remedial works. Sources of funding are expected to come primarily from the coal sales revenue and also external banking facilities of the Group.
In addition to coal mining, the Group has been exploring new markets and seeking to extend its business coverage on technological and renewable energy sectors, in particular, the acquisition of Harbour Group Holdings limited and its subsidiaries in 2019 and NEFIN Leasing Technologies Limited and its wholly-owned subsidiary, NEFIN Technologies (Malaysia) Sdn. Bhd. in 2018. It is one of the objectives of the Group to diversify its business portfolio into sectors offering higher growth momentum.
Due to the recent social and political instability in Hong Kong and the outbreak of coronavirus disease (COVID-19) worldwide, we are facing the most difficult business environment, which negatively impact the growth of our business, in particular IT services business in Hong Kong is expected to be hit hard by the prolonged social unrest in Hong Kong.
The Board will continue to keep track of the latest development of the COVID-19 and will use its best endeavors to manage the Group's business portfolio with a view to improve the Group's financial performance and enhance shareholders' value.

GEARING RATIO
The Group's gearing ratio was approximately 1.49 (2017: approximately 2.27). The computation is based on total debt (convertible bond designated as financial liabilities at fair value through profit or loss) divided by total equity.
CAPITAL STRUCTURE
The capital of the Group comprises only ordinary shares.
As at 31 March 2018, there were 765,373,584 ordinary shares of the Company in issue.
Zero coupon convertible bonds of the Company with an aggregate principal amount of HK$200,000,000 were issued on 14 March 2008 the maturity date of which was approved to be further extended for 36 months to 13 March 2020 by the shareholders of the Company on 7 March 2017.

APPENDIX I | FINANCIAL INFORMATION OF THE GROUP |
TREASURY POLICIES
Apart from the issuance of Convertible Bond at their face value of HK$200,000,000, the Group finances its operation mainly by internal generated resources.
CHARGES ON GROUP'S ASSETS
As at 31 March 2018, none of the Group's assets was under charges (2017: Nil).
EMPLOYEES
As at 31 March 2018, the Group had 73 employees (2017: 74) spreading between Hong Kong and the PRC. Total staff costs (excluding Directors' emoluments) for the Year amounted to approximately HK$10,266,000 (2017: approximately HK$10,041,000). Employment relationship has been well maintained by the Group with its employees. The Group has adopted an extensive training policy for its employees. It has also sponsored senior executives for higher education programmes.
FOREIGN EXCHANGE EXPOSURE
The Group mainly earns revenue in Renminbi ("RMB") and incurs costs in RMB and Hong Kong dollars. The Group is exposed to foreign exchange risk based on fluctuations between Hong Kong dollars and RMB arising from its core operation in the PRC. The currency exchange risk for the Year is mainly derived from the net exchange gain on convertible bond designated as financial liabilities at fair value through profit or loss, which is a result from the sustained depreciation of RMB against Hong Kong dollars. In order to minimise the foreign currency risk exposure between these two currencies, the Group maintained cash balances in both currencies that are sufficient to meet three to four months' operating cash flows requirements of the Group.
CONTINGENT LIABILITIES
As at 31 March 2018, the Group did not have any material contingent liabilities.

APPENDIX I | FINANCIAL INFORMATION OF THE GROUP |
PROSPECTS
The Board considers that the coal business is full of challenges and endeavors to achieve our goal of bringing maximum values for shareholders by strengthening management of the Company, controlling the cost of coal mining, cooperating with the national policies of developing economy in the western region, seizing new chances, exploring new markets, and seeking for investment opportunities in renewable energy and environmental engineering sectors.
Being cognizant of the impact of coal mining operations on the environment, we are committed to the implementation of environment management in compliance with laws and regulations. As coal mining inevitably generates emissions, the Group will increase investment in upgrading eco-friendly equipment, striving to mitigate dust dispersion in the production and storage process.
Regarding the Updated Optimization and Upgrading Plan, as explained above, Kaiyuan Company and Zexu Company have already followed the request from the Changji Land Department to enter into the Four Undisputed Agreements respectively to dispose of Zexu Mine and acquire the Kaiyuan Extended Area. The Company is now going through official procedures to apply for the exploration right and mining right in respect of the extended areas. The Company will make further announcement(s) as and when appropriate to keep shareholders posted of any further development of the Updated Optimization and Upgrading Plan.

FOREIGN EXCHANGE EXPOSURE
The Group mainly earns revenue in Renminbi ("RMB") and incurs costs in RMB and Hong Kong dollars. The Group is exposed to foreign exchange risk based on fluctuations between Hong Kong dollars and RMB arising from its core operation in the PRC. The currency exchange risk for the Year is mainly derived from the net exchange gain on convertible bond designated as financial liabilities at fair value through profit or loss, which is a result from the sustained depreciation of RMB against Hong Kong dollars. In order to minimise the foreign currency risk exposure between these two currencies, the Group maintained cash balances in both currencies that are sufficient to meet three to four months' operating cash flows requirements of the Group.
CONTINGENT LIABILITIES
As at 31 March 2019, the Group did not have any material contingent liabilities.
PROSPECTS

1.6 History
During the period 2006-2009, the Ninth Geological Brigade of the Xinjiang Geology and Minerals Bureau and the Shandong Taishan Geological Exploration Company carried out several exploration and drilling programs that defined the coal resources within the Property. Those resources were verified in 2018 by the Ninth Brigade. In 2019, a Feasibility Study, dated 31 August 2019, was completed by the Xinjiang Coal Design and Research Institute Co., Ltd. That Feasibility Study is reviewed in this report.
Mining of the original Kaiyuan Mine in the northern part of the Property began in 2008. To date, approximately ten million tonnes of coal have been produced from the Property.
1.7 Regional and Local Geology
The Junggar Basin originated south of the Siberian Craton during the late Paleozoic as a remnant ocean basin in which 3,000 to 4,000 m of marine volcaniclastic sediments were deposited. Early Permian and younger rocks are non-marine and were deposited in a subsiding basin formed by the uplift of the ancestral Tian Shan mountains. During Late Permian time, the basin transformed into an intercontinental basin and during the Early Triassic, the area became a shallow lacustrine basin. Coal beds are abundant and extensive in Lower to Middle Jurassic strata. Individual beds are up to tens of meters thick and are interbedded with lacustrine and fluvial sandstone and mudrock.
The Property area is underlain by rocks of Lower to Middle Jurassic age. The oldest rocks encountered in drilling belong to the Lower Jurassic Sangonghe Formation comprised of approximately 90 m of grey-green siltstone, fine-grained sandstone, and argillaceous siltstone. The Sangonghe Formation does not contain coal beds. The Sangonghe Formation is conformably overlain by the Xishanyao Formation of Middle Jurassic age that is comprised of basal conglomerate and coarse sandstone, grey to light-grey siltstone, mudstone and sandstone with coal seams. The Formation has an average thickness of approximately 125 m and is nearly flat-lying, with dips of 3° to 5° to the south. Jurssic starta are unconformably overlain by basal conglomerate and brown, yellow and red-yellow mudstone, siltstone and argillaceous siltstone that belong to the Upper Pliocene Dushanzi Formation.
The Property contains nine (9) coal seams of potential economic interest. From
oldest to youngest these are labelled B7, B8, B9, B13, B14, B15, B16, B17, and B18, and they have an aggregate thickness of approximately 50 m. (Table 1.1) All seams are
contained within the Middle Jurassic-age Xishanyao Formation and are essentially parallel, strike east-west, and dip approximately five (5) degrees to the south.
Seams B7 and B9 are the most continuous; seam B8, between B7 and B9, is restricted to the southern part of the expansion area. The remaining seams are generally continuous, but because they dip to the south, are progressively truncated to the north.

1.9 Drilling
Kaiyuan has drilled nine (9) holes within the Property, two (2) in the north-eastern portion of the Property and seven (7) within the expansion area. (Figure 1.1) Four holes (ZK401, 403, 505 and ZKJ607 were drilled in 2018 and five holes (ZK01, 02, 03, 04, and 05) were drilled in 2019.
Figure 1.1 Kaiyuan Drillhole Location Map
The Property and immediate area have been tested by an additional 33 holes, five (5) of which are within the area of the current pit and 10 of which are located outside the current Property boundary.
1.10 Mineral Processing and Metallurgical Testing
Several testwork programs have been conducted on Kaiyuan coal samples since 2017. The most recent is a preliminary coal property analysis campaign carried out in 2020 by SGS-CSTS Standards Technical Services (SGS Tianjin) in Tianjin, China on samples collected from drillholes ZK-01 to ZK-05 inclusive. Previous to that, the Ninth Geological Brigade of the Xinjiang Geology and Minerals Bureau (NGB) reported the results of a comprehensive coal property analysis in their 2018 reserve verification report. Preliminary coal washability test results were included in the 2018 reserve verification report as well as in the 2019 PEA report. Major findings were:
- Kaiyuan coal is a low-rank bituminous coal with no coking abilities and is classified as non-coking coal BN31 according to the Chinese classification system. This is equivalent to the Sub-bituminous B coal class according to the American Society for Testing Materials (ASTM D-388).

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
- Kaiyuan coal is low in ash with stable moisture and volatile matter, especially for the major coal seams B7, B9, B13 and B14 (Table 1.3). The average ash content for these seams is in the range of 7.0% to 17.5% on a dry basis.

- Kaiyuan coal has low concentrations of deleterious elements of sulphur (S), phosphorous (P), fluorine (F), and arsenic (AS). Some samples from Seams B7 and B9 had a chlorine content of more than 0.3%. Kaiyuan float samples have a lower sulphur content, while the distribution of P is consistent.
- Kaiyuan coal can be used as thermal coal because of its high heating values. However, the high concentration of the alkali elements will affect the fusibility and cause slagging during combustion. Kaiyuan coal has no coking properties. It may be used for coal gasification.
- Medium levels of humic acids were identified from the weathering zone as reported in the 2018 and 2020 reserve verification reports. The potential economic values of the weathered coals have been discussed in the 2018 PEA and 2019 FS reports.
- Washability tests on core samples indicate that Kaiyuan coal has a low degree of separation difficulty based on Chinese criteria. Washability tests on raw coal samples from nearby coal mines confirm this observation.

The Kaiyuan mine has been in operation since 2008, producing as-mined coal which is screened to various sizes for the local thermal coal market. PVMA has reviewed production data for the period 2017 to 2019 inclusive, quality data of recent coal core samples, the operation of adjacent coal mines, and coal quality projections based on the current resource estimate. It was concluded that as-mined raw coal meets the quality requirements for the life of mine. The projected raw coal quality for the life of mine is shown in Table 1.4.

Production data for the period 2017 through 2019 are listed in Table 17.1 together with fine coal product quality data. The ash content is low, in the range of 5.4% to 8.4% and the net heating values for 2017 and 2018 are higher than the required 18 MJ/kg. According to Kaiyuan, the low-quality coal production in 2019 was the result of mining of low-quality coal Seam XB2 that has been almost completely mined out.

1.11 Mineral Resource Estimate
PVMA has carried out an estimate of coal resources within the southern (expansion) portion of the Property on the basis of drillhole data provided by Kaiyuan that included drillhole collar locations, depth of coal seams, surface topography as of September 2019, and ash content (Ad%), moisture (Mad%), volatile content (Vadf), and net calorific value of dry coal (Qnet, d (MJ/Kg)). Geological strip logs were available for several of the drillholes but most collar, seam depth and thickness information were extracted from information plotted on geological long sections through the Property. Coal quality data were obtained from the 2019 resource verification report.
Location and coal seam interval data was obtained for 42 drillholes of which 26 holes were inside the expansion area and were used to estimate the quantity of coal. The dataset includes 191 coal seam intercepts of which 115 are located within the expansion area of the mining licence. Of the 332 coal quality analyses, 221 are located within the boundaries of the mining licence.
All seams were modelled as south-dipping sheets using the vertical, intersected thicknesses from each of the drillholes located within the boundaries of the Property.
Coal intercepts were assigned an indicator value of one (1) and all waste had a value of minus one (-1). Coal quality data were entered into the model using sample lengths given in the resource verification report. Samples were then segregated by coal seam and composited to three (3) meters length.
One hundred fifteen (115) bulk density measurements were carried out on all nine major coal seams by the Xinjiang Bureau of Geology and Mineral Resources and reported in the 2018 Resource Verification Report. The average for all measurements is 1.34 g/cm3.
- II-8 -
APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
Although the seams are more extensive than the limits of the Property, they have been modelled only to the limits of the Property boundary because the Company is allowed to mine only within the boundaries of the Property and to a depth of 575 meters above sea level, therefore the existence of any coal measures beyond those boundaries is irrelevant to the exercise of resource estimation.
The volume of the coal seams was estimated using a search ellipse with a diameter of 500 meters, thickness of 50 meters, and a south dip of five degrees. The size ensured that the ellipse would capture holes on two adjacent north-south lines and the dip ensured that the ellipse would honour the dip of the seams. Coal quality was estimated using inverse distance squared (ID2). Coal quality was estimated within each of the seams using data for that seam only.
Block model parameters are given in Table 1.3.

X | 30531000 | 100 | Columns | 91 |

Z | 477.5 | 5 | Levels | 63 |
- Minimum X, Y, and Z Model is not rotated
The coal indicator (value of 1) was interpolated into the blocks in a single pass. In order for a value to be interpolated into a block it was necessary that a minimum of two (2) and a maximum of four (4) intercepts be located within the volume of the search ellipse. As each seam in each drillhole was represented by a single indicator, the minimum requirement of two intercepts means that each block was informed by a minimum of two drillholes.
Because at least some of the coal seams extend to surface and all of the seams will be exploited by open pit mining methods, it is necessary to constrain the resource estimate by a design pit that is based on reasonable cost and revenue values. A design, break-even pit was constructed using a current mining cost of RMB64 per tonne and a selling price of RMB140 per tonne. Processing cost was assumed to be zero, mining dilution was assumed to be zero and mining recovery 100 percent. An overall pit slope of 38 degrees, the same as the current mining operation, was used to define the ultimate pit walls.
Because drillholes are generally 200 meters or less apart on lines that are at most 500 meters apart, and the coal seams are exposed in active open pit mines on the east, north and west sides of the expansion area, there is very strong evidence for the continuity of the coal seams within the expansion area. For this reason, all resources have been classified as Indicated.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
The pit-constrained resource estimate for the expansion area is set out in Table
1.4. The resource has been estimated only to 575 meters above sea level, the minimum elevation of the mining licence.

1.12 Mineral Reserve Estimate
The summary of open pit coal reserves is shown in Table 15.1. Note that the coal reserves are rounded up to nearest 100,000 and above elevation 575 as per the mining licence. The reserves only are reported for the South region of the mining license. These reserves do not include the North region of the current active mining area.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
The mineral reserves have been determined using costs set out in Table 1.9.

Parameters | Value |
Mining | CNY 58.46*/tonne coal |
Coal Preparation & General Administration | CNY 7.81/tonne coal |
Overall Wall Slope | 38 deg. |
Coal Price | CNY 140/tonne coal |
Coal Production Rate | 900,000 tpa |
Source: PVMA (2020)
- Operating Costs exclude amortization, depreciation and interest expense of 0.16, 9.49 & 0.5 CNY/t, respectively.
The mining, coal preparation and general administration costs are referenced from the 2019 FS. The mining costs are based on CNY per tonne coal, which equates to CNY9.9 per tonne of material. The basis for the mineral reserve estimate is used in the following Lerch-Grossman optimization. Also, the operating cost summary is based on a 900,000 tpa, which is conservative compared to the 1,200,000 tpa allowable coal release. Since there is a 33% increase in coal production, the operation should realize a lower operating cost over the life of mine.
A percentage block model developed for Section 14, was transferred into the Maptek VulcanTM software. A Lerch-Grossman (LG) Pit Shell optimization was conducted to validate the mineral reserve estimate. The parameters for the optimization used are set out in Table 15.2.
The LG optimization shell resulted in a pit-constrained reserve of 69.5 million tonnes with an overall strip ratio of 5.44:1 (waste tonnes: coal tonnes). The reserves shown in Tables 1.8 and 1.10 are constrained by the lower limit of the mining licence (575 masl) in addition to the pitshell and total 63.5 million tonnes with an overall strip ratio of 5.91:1. Dilution factor of 0.5% and Mining Losses average 5.4%. These are reasonable for this type of estimate.
The coal reserves by seam are shown in Table 1.10. Note that the coal reserves are rounded up to nearest 1,000 and above elevation 575 m as per mining licence.

Notes: tonnes are reported to the nearest thousand. Rounding as required by reporting guidelines may result in apparent summation differences; t = tonnes; w:o = stripping ratio of waste to coal ore
The mine production schedule from the FS was based on 900,000 tonnes per year. The increase is due to the Safety Production Permit allowing the coal output to increase to 1.2 million tonnes per year. During the period 2017 to 2019, coal output was 2.09, 2.08 and 1.441 million tonnes per year. Since there is no coal release in this latest production schedule during pre-production, this gives the mine significant time to allow stripping to be performed without coal release disturbance. Coal release will continue in the north portion of the mining lease during stripping.
- II-16 -
APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
The coal quality data presented in the annual mine plan is based on coal release presented in the year of mining and blended based on the seams that are exposed. The calorific values, volatile matter, moisture and ash content indicates that the coal falls within the limits of marketable coal, therefore requiring no washing. The coal preparation plant will be required as function of the coal contracts.

Source: PVMA (2020)
To increase coal production to 1.2 million tonnes per year, adjustments to waste material removal had to be increased in the first seven years. Pre-stripping shows approximately 10 million tonnes of material in year 2022. During years 2023 to 2025, waste stripping increases to 8.8 million tonnes per annum, then reduces gradually during years 2026 to 2038 to approximately 6 million tonnes and 3 million tonnes, respectively. It then increases up to approximately 8 million tonnes from 2036 to 2039. Pre-stripping will also release approximately 1.2 million tonnes of coal ore in year 2023 and for the life-of-mine. The strip ratio will average 5.9 over the life-of-mine.
Over the life of mine, the mine will produce approximately 374.9 million tonnes of waste rock and overburden material. The mine has two dumping locations; the internal in-pit dump located North of the First phase mining area and the Northern Outer (Beiwai) dump site located on the North side of the mining lease and outside of the pit (ex-pit).
All mining activities on site will be completed by a combination of owner and local contractors. The descriptions in this section provide general information on the size and/or capacity of the selected equipment. This operation is a conventional truck-and-excavator operation. Track-mounted blasthole drills, either rotary drilling or down-the-hole (DTH), are used. All equipment on site is and will be diesel powered.

The increase to 1.2 million tonnes per year of coal production from the originally planned 900,000 tonnes per year, also increased the total number of excavators by one to a total of four and 45-tonne trucks by eight units to a total of 19 to meet the additional material movement requirements. Remaining equipment will be sufficient to manage the 1.2 million tonnes per year of coal release. The 25-tonne class highway truck is for the transportation of coal to market. The number of trucks is variable due to the number of contract sales which varies year to year and is also depended on location for delivery.
Overburden and rock stripping will require blasting which is managed by the contractor. Blast designs are based on 10-m benches and 1-msub-drill, using a powder factor of approximately 0.33 kg/m3 for rock and 0.22 for coal kg/m3. Over the life of mine, the project will use approximately 1.1 million kg per year of bulk ammonia-nitrate and fuel-oil explosive. The project will use conventional blasting products: non-electric detonating cords, delays and boosters. Blasting considerations of explosive timing and quantity of down-the-hole product will be adjusted for blasting near facilities.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
Management staff will be owner-represented and will comprise 11 personnel. Personnel was increased to accommodate the 1.2 million tonnes per year coal production and will be comprised of 232 production staff, 9 service personnel, 9 other personnel, 6 safety personnel and 6 outsourcing staff, totalling 259 mine workers.
Over the life of mine, the project will consume approximately 10.0 million liters of diesel fuel per year.
1.14 Recovery Methods
The Kaiyuan coal mine has been in operation since 2008, producing as-mined coal which is screened to various sizes for the local thermal coal market. The as-mined raw coal meets quality requirements for the life of mine.
Kaiyuan coal is low rank bituminous. Tested coal core samples from the 2018 and 2020 sampling programs indicate that in general, Kaiyuan coal contains low ash as well as low concentrations of deleterious elements including total sulphur, phosphorous, fluorine and arsenic. Some core samples from Seam B9 have a chlorine content higher than the threshold level 0.3%, although most of the measurements are lower than this. The heating values of the core samples are high, in the range of
25.6 to 28.4 MJ/kg without processing. These properties indicate that the run-of-mine coal can meet thermal coal market requirements.
Large samples collected from the nearby mines confirmed the low ash and sulphur content as well as the high heating value of the coal as seen from the coal washability test results of Heishantou and Beishan samples. The raw coal ash on a dry basis was reported as 5.4% and 10.2% for Beishan and Heishantou, respectively.
The average coal quality during the life of mine was estimated by PVMA for the Property of the basis of proximal analyses included in the 2019 resource verification report. The average and range data are listed in Table 1.15. During the proposed life of mine, about 63.5 million tonnes raw coal will be produced, which will have an average net heating value of 26 MJ/kg and an ash content of 10.4% on a dry basis. The lowest net heating value of the raw coal was projected as 23 MJ/kg, which is above the lowest heating value regulated by local authority and meets the regional thermal coal market requirements.

1.15 Project Infrastructure
The location of the mine provides with easy access to provincial roads and highways. The mine has an open pit production system and auxiliary facilities including maintenance shop, office building, and dormitories. These facilities are currently located to the south of the mine but will be relocated to the north-east for future mining. A new screening plant has been constructed on site and is also located in the same area.
Kaiyuan will use dual power supplies. One existing power supply is provided by the 35 kV Beishan transformer station. A second power source will be provided by the proposed 110 kV substation of the Jinneng Mine via a 4 km, 10 kV powerline. Three diesel generators are also available as an emergency power supply. The highest daily water consumption was estimated to be 701 m3/d for operation, as well as potable and sanitation water uses and will be provided using both reclaimed and fresh water.
1.16 Market Studies and Contracts
Kaiyuan as-mined coal is screened to various sizes and sold on a ROM basis to the local thermal coal market. The mine has an established thermal coal sales market with low risk for future sales. Typical coal products are shown in Table 1.16.

1.18 Capital and Operating Costs
All capital and operating cost estimates are reported in Renminbi (CNY) unless stated otherwise. Note that the initial study was based on a production rate of 900,000 tonnes per year coal production as per the mining permit. The safety production permit allows coal production to increase to 1.2 million tonnes per tonne per year. The capital therefore has been updated by the author to reflect the purchase of additional equipment required to accommodate the 1.2 million tonnes per year production plan. Operating costs were not updated and therefore the use of the 900,000 tonne per year operating costs for the 1.2 million tonne per year operation should be result in lower costs is considered to be a conservative evaluation.

The mining costs are a fixed cost based on annual mining of 900,000 tonnes of coal per year of operation due to the mining permit. The safety production permit allows coal production to increase to 1.2 million tonnes per tonne per year. Operating costs were not updated and should be realized at a lower cost and therefore the 900,000 tonnes per day operating costs is used as a conservative evaluation and within the limits of this study.

1.19 Economic Analysis
All values are reported in Renminbi (CNY). The initial study was based on 900,000 tonnes per year coal production as per the mining permit. The safety production permit allows coal production to increase to 1.2 million tonnes per tonne per year. The economic analysis has been updated by the author to reflect additional equipment purchases necessary to accommodate the 1.2 million tonnes per year production plan. Operating costs were not updated and should be realized at lower cost and therefore the 900,000 tonnes per day operating costs is used as a conservative evaluation. Table 1.25 shows the economic analysis summary.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
- ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE AND PHYSIOGRAPHY
The Property is located on the southern margin of the Junggar Basin in northeastern Xinjiang Autonomous Region, near the border with Mongolia, but is readily accessible: A recently completed freeway extends from Urumqi approximately 150 km east to Qitai. From Qitai, the Property is reached by travelling approximately 20 km east on Provincial Road S303 then 50 km north on Provincial Road S228 at which Provincial Road S327 branches to the northeast and passes within several kilometers of the Property. Roads within the Property are maintained but unpaved. A railway is under construction parallel to Highway S327.
The Junggar Basin is bordered by the Altai Mountains on the north and by the Borohoro and Eren Habirga Mountains immediately north of the Tienshan Mountains on the south. The area is remote from any marine climatic influences and therefore has a dry, continental climate. Precipitation not only is scanty but also fluctuates widely from year to year. On average, annual rainfall is about 165 mm. Average January temperatures in the Junggar Basin are about −15 °C and average temperatures in summer vary from 21°C in the north to 24°C in the south. Mining activities are conducted on a year-round basis.
The Property is at an elevation of approximately 700 meters above sea level (masl) and the terrain is essentially flat. Vegetation is scarce and is limited to scattered grasses and bushes where intermittent water flow is sufficient to support their existence.
The Property is relatively remote and other than several other coal mines, is not close to any significant infrastructure although the existence of a well-developed coal mining industry means that all necessary services are available in the region. Qitai County, in which the Property is located, has a population of approximately 250,000. The town of Qital, the county capital, is approximately 50 km south of the Property and offers basic services and all other supplies and services are available in Urumqi, approximately 200 km to the southwest.
The Property has sufficient surface rights for mining operations, waste disposal and processing plant sites. Electrical power is supplied to the Property from the Kitayama 35 kV substation, 10 km to the southwest. Water for industrial use is obtained locally but potable water must be transported to the Property from Penghu, 35 km to the southwest.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
- HISTORY
The documented history of coal exploration of the Property area dates from 2006-2007, when the Ninth Geological Brigade of the Xinjiang Geology and Minerals Bureau conducted a coal exploration program on the Mingjia Kaiyuan Open-pit Coal Mine that included a topographic survey, prospecting and a hydrological test.
During 2007-2008, the Shandong Taishan Geological Exploration Company carried out an exploration program at the Heshantou Coal Mine where they carried out a topographic survey, geological mapping, trenching and 6,686 meters of drilling in 34 holes. This work was done for Zijin Mining Group Co. Ltd.
During 2008-2009, the Ninth Geological Brigade of the Xinjiang Geology and Minerals Bureau worked on the Beishan Coal Mine, to the west of the Property, on behalf of Xinjiang Beishan Mining Co. Ltd. This program included topographic and geological and hydrogeological mapping, prospecting and 2,050 meters of drilling in 14 holes.
In 2018, the Ninth Brigade of the Xinjiang Geological and Mineral Bureau prepared a reserve verification report on the Kaiyuan Mine.
In 2019, the Xinjiang Coal Design and Research Institute Co., Ltd. completed a Feasibility Study, dated 31 August 2019, that was based on the 2018 resource verification report. The current ITR is based on a review of the 2019 Feasibility Study.
The portion of the Property into which the mining operation is expanding (expansion area) was previously owned by two companies, Jinneng and Beishan.
Mining of the original Kaiyuan Mine in the northern part of the Property began in
2008. To date, approximately ten million tonnes of coal have been produced from the Property.

GEOLOGICAL SETTING AND MINERALIZATION
7.1 Regional Stratigraphy
The Junggar basin formed south of the Siberian Craton during late Paleozoic time as a remnant ocean basin that was bounded by emergent volcanic arcs. A regressive sedimentary sequence comprising 3,000 to 4,000 m of marine volcaniclastic rocks was deposited in this basin. Devonian-age sandstones are entirely volcaniclastic which suggests that the basis is underlain by oceanic crust. Early Permian and younger rocks are non-marine and were deposited in a subsiding basin formed in response to the uplift of the ancestral Tian Shan mountains.
- II-51 -
APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
More than 2,000 meters (m) of shallow-marine arenite and mudrock were deposited in the southeastern margin of the Junggar Basin during Early Permian time. During Late Permian time, the basin transformed into an intercontinental basin and during the Early Triassic, in response to repeated uplift and subsidence, the area became a shallow lacustrine basin. During the Middle and Late Triassic, approximately 1,200 m of mudstone and sandstone were deposited in the southeastern part of the basin.
Coal beds are abundant and extensive in Lower to Middle Jurassic strata. Individual beds are up to tens of meters thick and are interbedded with lacustrine and fluvial sandstone and mudrock.
The Lower to Middle Jurassic Xishanyao Formation was variably eroded and unconformably overlain by the upper Middle Jurassic Toutunhe Formation.
Cretaceous-aged rocks are over 3,000 m thick and are comprised of basal conglomerate and interbedded sandstone and mudstone. During the Paleogene, more than 1,500 m of mudrock, sandstone and conglomerate were deposited in the south-central Junggar Basin. The Paleocene-Eocene age Ziniquanzi Formation is composed of sandstone and intercalated mudstone with common lateral facies changes. The middle portion of the Eocene-Oligocene age Anjihiathe Formation is composed of thick shale beds intercalated with limestone and the upper and lower parts are comprised of interbedded mudstone and sandstone that were deposited in a littoral lacustrine environment.
From Miocene to Quaternary time, sediments were deposited in depressions formed by northward thrusting and loading of the northern Tianshan mountains caused by collision of the Indian and Eurasian plates. Miocene deposits are mostly fluvial-lacustrine mudstone intercalated with sandstone, conglomerate and limestone. Pliocene deposits are mainly alluvial fan to fluvial mudstone and sandstone interbedded with conglomerate. Quaternary deposits are alluvial fan to fluvial conglomerate and sandstone.
Figure 7.1 is a stratigraphic column showing the formations, lithologies, and fossils that make up the Mesozoic strata in the southern Junggar Basin. (From Li et al,
2014)
7.2 Property Stratigraphy
The Property area is underlain by rocks of Lower to Middle Jurassic age. The oldest rocks encountered in drilling belong to the Lower Jurassic Sangonghe Formation. Rock types include grey-green siltstone, fine-grained sandstone, and argillaceous siltstone and are approximately 90m thick. The Sangonghe Formation does not contain coal beds. Regionally, the Sangonghe Formation is described as being comprised of coarsening-upward cycles that represent multiple delta progradations along basin margins. The thin-bedded,fine-grained and well-sorted sandstones with wide lateral extent are indicative of wave-dominated delta systems. Adjacent to the Property, the Sangonghe Formation contains conglomerate beds which may be indicative of fluvial channels.
- II-52 -
APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
The Sangonghe Formation is conformably overlain by the Xishanyao Formation of Middle Jurassic age. The Xishanyao Formation is comprised of basal conglomerate and coarse sandstone, grey to light-grey siltstone, mudstone and sandstone with coal seams. The Formation has an average thickness of approximately 125 m and is nearly flat-lying, with dips of 3° to 5° to the south.
Figure 7.1 Stratigraphic Column Mesozoic Junggar Basin
Jurssic starta are unconformably overlain by basal conglomerate and brown, yellow and red-yellow mudstone, siltstone and argillaceous siltstone that belong to the Upper Pliocene Dushanzi Formation. The basal strata are purple to brick red. The formation has an average thickness of approximately 10 meters and thins from north to south.
- II-53 -
APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
The southern part of the Property is overlain by Quaternary-age sand and gravel that is up to 12 meters thick.
7.3 Mineralization
Within the Property, all coal seams are contained within the Middle Jurassic-age Xishanyao Formation. There are nine seams of coal of sufficient thickness to be recoverable and they have an aggregate thickness of approximately 50m. The seams are listed in Table 7.1 together with their average, minimum, and maximum thickness.
Table 7.1 Kaiyuan Coal Seam Thickness
Average | Minimum | Maximum | |
Coal Seam | Thickness | Thickness | Thickness |

B8 | 1.4 | 0.5 | 1.8 |
B7 | 21.2 | 12.5 | 24.5 |
The seams dip to the south at approximately five (5) degrees. Seams B7 and B9 are the most continuous; seam B8, between B7 and B9, is restricted to the southern part of the expansion area. The remaining seams are generally consistent in thickness and distribution, but because they dip to the south, they are progressively truncated to the north. See Figure 7.2, a plan view of the seams and Figure 7.3 for a long section view.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
- DEPOSIT TYPES
The Kaiyuan Property contains seams of thermal coal. A general description of thermal coal deposits follows.
Geological characteristics: Seams of black to brown coal hosted by clastic sedimentary rocks. The coal is banded dull and bright and generally hard. The texture of the original vegetation is sometimes partially preserved.
Tectonic setting: Stable continental basins; shelves on the trailing edge of continents; foreland basins; back-arc basins.
Depositional environment: An area of slow sedimentation in fresh water with few or no marine incursions, most commonly a river delta; shoreline swamp; raised swamp; lake; floating vegetation mats.
Age of mineralization: Often Tertiary but can be older.
Host/Associated rock types: Sedimentary rocks exhibiting evidence of non-marine deposition. Carbonaceous mudstones, siltstones and sandstones are the most common, commonly with cross-stratification and other shallow-water sedimentary structures.
Deposit form: Coal seams generally conform with regional bedding; sometimes seams are deposited in areas of local subsidence, such as fault-controlled blocks or sink holes in karst topography, in which case deposits may be lens shaped. Occasionally seams can be thickened/deformed by surface slump, glacial drift or faulting. Seams may pinch out or split on a local or regional scale.
Texture/Structure: Sub-bituminous coal is usually composed mostly of clarain and vitrain. Footwall sediments are commonly penetrated by roots or weathered to clay.
Coal seams/Associated mineral matter: Sub-bituminous coal can contain up to 30 % moisture. It usually contains a high proportion of vitrinite and lesser amounts of fusinite and liptinite. Mineral matter is in the coal as rock bands, as finely intermixed material of authigenic or detrital origin and as secondary material deposited in fractures and open spaces. Authigenic mineral matter includes pyrite, siderite and kaolinite.
Weathering: Weathering of sub-bituminous coal reduces the calorific value by oxidizing the carbon-hydrogen complexes. Minerals in the mineral matter will also oxidize. Pyrite oxidizes to sulphates. Secondary carbonates are formed.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
The following description of drilling procedures pertains to the holes drilled on behalf of Kaiyuan. A description of procedures followed during the drilling of earlier holes is not available but, as all drilling procedures must adhere to government regulations, it is reasonable to assume that they closely followed the Kaiyuan procedures. Drilling was carried out using a truck-mounted drill. Holes had an outside diameter of 110
- and an inside (core) diameter of 56 mm. Collar locations were located using GPS with millimeter accuracy and were tied into national grid benchmarksAll holes were drilled vertically so that intersected thicknesses are essentially true thicknesses. Hole depth, core recovery and water level in the hole were monitored on a regular basis during drilling.
Drillholes were surveyed geophysically to determine the depth and thickness of coal-bearing intervals, density of rock, as well as to monitor the location and diameter of the hole. Downhole logging tests included: Density, Natural Gamma, Resistivity, Self-potential, Sound velocity, Down-hole direction, Hole diameter and Well temperature. Graphic logs of the surveys were produced for each hole.
All processing of drillcore took place at the drillsite. When core was removed from the core tube it was placed into wooden core boxes. Figure 10.2 shows boxes of core from hole ZK01. This interval includes a unit of coal.
Figure 10.2 Kaiyuan Drillhole ZK01 Core from Depth Interval
All core was photographed after being placed in the corebox and was measured for core recovery. The core was then described, and intervals were identified for sampling. Core recovery was approximately 97% and met government requirements for all holes.
- II-59 -
APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
The entire core was taken for analysis therefore no archival samples of coal seams remain. Thinner coal seams were collected as a single sample; for thicker seams, samples were up to three meters in length. Samples were placed into labelled double plastic bags which were then placed into sealed plastic boxes for shipping. Samples were sent by train to SGS in Tianjin for analysis. The drillcore that remained after sampling of the coal seams was stored in a locked building and was inspected during the site inspection in January 2020.
The drillsite and all samples were secured and supervised at all times by personnel of the Xinjiang Bureau of Geology and Mineral Resources.
When the drillholes were complete, they were sealed, and the location was marked with a cement monument that identified the number of the hole as well as the start and completion dates.
11 SAMPLE PREPARATION, ANALYSES AND SECURITY
Sampling of the drillcore was done at the drillsite and the coal seam intercepts in each drillhole were sampled in their entirety. In total, 84 samples were collected from the five holes drilled in 2009.
After the core was taken out of the borehole, it was put into the core box in order, photographed, then described. Samples were taken after the core was logged. For those coal seams less than three meters in thickness, the seam was collected as a single sample; otherwise, samples were collected in three-meter increments.
Core samples were placed in plastic bags that were closed with tape. Each sample bag was numbered, and the bags were placed in boxes for shipping. The boxes of samples were shipped by China Railway Express to SGS Mineral Energy Laboratory in Tianjin. SGS is an internationally recognized, ISO-certified analytical laboratory. Secure chain of custody of samples was maintained at all times from the drill to the laboratory.
No quality control samples were submitted with the core samples but SGS maintains a rigorous program of internal QA/QC for all their analytical processes and because the Property is an operating mine and the quality of the coal is well-understood and the SGS analyses are consistent with the known quality of the coal, the absence of quality control samples is not regarded as a deficiency.
The author (Mosher) is of the opinion that the sample preparation, security and analytical procedures are appropriate and adequate for the results to be used for the resource estimate described in Section 14 of this report.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
12 DATA VERIFICATION
The author (Mosher) took the following steps to verify the data from the 2019 drill campaign:
- Site inspection during which each of the drillhole locations was inspected and the coordinates recorded;
- Inspection of the drillcore remaining from holes ZK-01 to 05;
- Discussions with the Xinjiang Bureau of Geology and Mineral Resources manager of the drill program regarding drilling protocols and procedures;
- Review of analytical data from all holes used for the resource estimate.
No samples were collected as (a) the coal-bearing intervals from holes ZK01 through 05 were sampled in their entirety and submitted for analysis and (b) several of the seams (B7 and B9) are exposed in the wall of the adjacent open pit so their existence is obvious and as these seams have been exploited for a number of years, their characteristics are well established.
The author is satisfied that the data was collected and documented according to standards that are adequate for the purpose of the resource estimation that is described in Section 14 of this Technical Report.
13 MINERAL PROCESSING AND METALLURGICAL TESTING
Several testwork programs have been conducted on Kaiyuan coal samples since
2017.
- The most recent work is a preliminary coal property analysis campaign carried out in 2020 by SGS-CSTS Standards Technical Services (SGS Tianjin) in Tianjin, China on samples obtained from the 2019 drill program.
- In 2018, the Ninth Geological Brigade of the Xinjiang Geology and Minerals Bureau (NGB) reported the results of a comprehensive coal property analysis in their 2018 reserve verification report. A preliminary coal washability test, based on both 2019 drill samples and a production sample from the nearby Beishan Coal Mine (Beishan), was also included in the report.
- II-61 -
APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
- Additional coal washability test results, based on the production coal samples from the nearby coal Heishantou Coal Mine, were reported by the Xinjiang Coal Design and Research Institute in their 2018 Preliminary Economic Assessment (PEA) report). The test was conducted by Xinjiang Uyghur Autonomous Coal Science Research and the results were used as the design basis for the Kaiyuan coal preparation plant in the PEA report.
PVMA reviewed the 2020 SGS test reports and the 2018 Xinjian Coal Science Research report, together with the processing test results reported in the 2018 reserve verification report and in the 2018 PEA report. The major test results and the review comments are summarised as follows:
13.1 Samples Description
13.1.1 2020 Kaiyuan Coal Samples
A total of 84 drill core and composite samples from holes ZK-1 to ZK-5, drilled in 2019, (Figure 10.1) were assayed in the 2020 SGS coal property analysis test program, including 69 drill core samples and 15 composite samples for proximate analysis. Float clean coal samples were further produced from each sample and tested for the same analyses.
13.1.2 2018 Kaiyuan Coal Samples and Beishan Coal Samples
As described in the 2018 reserve verification report by NGB, both drill samples and pit samples were tested for coal property and washability.
- Drill coal samples were composited across the four drill holes (ZK401, ZK403, ZK505 and ZKJ607) from the nine coal seams (B7 to B9 and B13 to B18). The drill hole location can be found in Figure 10.1 of this report.
- A large-scale sampling program was conducted by collecting pit samples from Beishan Coal Mine to evaluate coal washability characteristics of Kaiyuan coal. Coal samples of 20 tonnes from seam B9 and of 17 tonnes from seam B7 were obtained for washability studies.
13.1.3 2018 Heishantou Coal Samples
Samples as described in the 2018 PEA report were obtained from the
Heishantou Coal Mine to represent the future Kaiyuan coal for a large-scale coal washability test. The total weight of the raw coal samples was approximately 10 tonnes from coal seam B6.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
13.2 Major Characteristics of Kaiyuan Coal
Coal properties are critical in evaluating potential coal uses, which can be either metallurgical, thermal for combustion, or new fuel materials via coal liquefaction and coal gasification. The 2020 SGS test was focused on basic proximate and ultimate analyses; the 2018 test as reported by NGM is more comprehensive, covering the fundamental tests plus coal carbonization, combustion, and conversion tests.
13.2.1 Kaiyuan Coal Ranking
Based on test results from petrological and microscopic examination (maceral groups), Kaiyuan coal is low-rank bituminous with no coking abilities and is classified as non-coking coal BN31 according to the Chinese classification system, equivalent to the Subbituminous B coal class according to the American Society for Testing Materials (ASTM D-388).
The major observations from microscopic examination are as follows:
- High organic components are found in all the coal seams and averaged from 90% to 94%, with vitrinite and inertinite as major components and exinite as a minor component.
- Inorganic components mainly include clay minerals, carbonates, sulphides, and oxides. The average content of inorganic components is between 5.6% and 9.1%.
- Maximum reflectance of the vitrinite component is between 0.4% to 0.5% and indicates that Kaiyuan coal belongs to a low-rank coal category according to Chinese standard MT/T 1158-2011 (Classification of coalification degree by vitrinite reflectance).
13.2.2 Proximate Analysis
Proximate analysis is the most widely used coal analysis to determine
moisture, ash, and volatile matter contents. Fixed carbon can also be obtained by difference. The 2018 analysis data are given in Table 13.1. The average moisture (Mad) ranged from 9.7% to 12.3%; the average ash (Ad) content is between 6.9% and 16.3%; the average volatile matter content ranged from 30.5 to 33.8 %. The 2020 analysis data is shown in Table 13.2, with a lower average moisture between of 5.6 to 8.8%, but a higher ash content from 5.8% to 23.8%. In the opinion of PVMA, for the major coal seams B7, B9, B13 and B14, the tested samples are low in ash with stable moisture and volatile matter as can be seen from the combined proximate results (Table 13.3).

The chemical composition analysis was conducted on coal samples, including the determinations of carbon (C), hydrogen (H), nitrogen (N), oxygen (O) plus sulphur (S).
The chemical elemental analysis results are shown in Table 13.4, which indicate all the samples have stable distributions of t C, H, N and O+S.
- The 2018 core samples from coal seams B7 to B18 have a stable distribution of carbon, hydrogen, nitrogen, and oxygen plus sulphur. The average contents of the core samples varied from 71% to 88% for C, 3.6% to 4.4% for H, 0.8% to 0.9% for N, and 14% to 17% for O+S.
- Similar trends were observed for the 2018 float coal samples produced from drill core samples. The reported contents for float coal samples are between 73% to 80% for C, 2.7% to 5.1% for H, 0.3% to 1.0% for N, and 11% to 16% for O+S.

13.2.4 Deleterious Elemental Analysis
Coal contains varying amounts of deleterious elements. According to the latest coal quality management regulation in China, Interim Measures on the Quality Management of Commodity Coal (effective since 2015), total sulphur (St), mercury (Hg), arsenic (As), phosphorous (P), chlorine (Cl) and fluorine (F), must meet the regulated levels for activities involved in production, processing, storage and transportation, as well as domestic sales shown in Table 13.5 Regulated Deleterious Elemental Levels of Commodity Coal in China.

Lignite | ≤1.5 | ≤0.15 | ≤0.3 | ≤200 | ≤80 | ≤0.6 |
Other Coal | ≤3.0 |
Kaiyuan coal samples were investigated to determine the levels of the deleterious elements including St, P, Cl, F and As. The results are given in Table 13.6. In general, the Kaiyuan core samples have low concentrations of the measured elements except for chlorine. The chlorine content is between 0.17% from seam B8 to 0.31% from seam B9. Kaiyuan float samples have a lower sulphur content, likely due to the observation that sulphides are major sulphur bearing minerals, while the distribution of P is consistent between the core and float samples.

13.2.5 Coal Utilization Tests
The utilisation possibilities of Kaiyuan coal were investigated and reported in the 2018 Reserve Verification report. The test work includes coal carbonization, combustion, and conversion tests as summarised as follows.
13.2.5.1 Carbonization Testing
Carbonization tests or caking tests are conducted to understand the coking ability of the tested coal to identify if the coal can be used to produce metallurgical coke. The reported Caking Index (G), which is referred to as the Rogan Index, is zero for all the core samples from each coal seam, with a low char residue characteristic index (CRC) between 1 and 2. The results indicate that Kaiyuan coal is not a coking coal.
13.2.5.2 Combustion Testing
Combustions tests determine calorific values, coal ash-fusibility, and coal ash composition.
The reported calorific value of Kaiyuan Coal core samples is between 25.6 and 28.4 MJ/kg, based on the gross calorific value or higher heating value. Considering a concentration of hydrogen of 5% and a 15% moisture, the net heating value is estimated to be approximately 24.2 to 27.0 MJ/kg, which is above the required net heating value of 18 MJ/kg as stipulated in local regulations. The tested calorific values indicate that Kaiyuan coal can be used as thermal coal.
The coal ash-fusibility testing results show that the softening temperature of Kaiyuan coal ash is between 1,077 and 1,125oC, which belongs to a low softening temperature class.
The coal ash composition of Kaiyuan core samples are presented in Table 13.7. The results indicate that Kaiyuan coal are high in basic oxides, Fe2O3, CaO, MgO, Na2O and K2O.

Kaiyuan coal samples are high in alkali metals, namely sodium and potassium, with a Na2O range from 4.5% to 7.5%, and K2O from 0.5% to 1.3%. The high alkaline content will impact the fusibility and slagging potential in coal combustion. According to the 2018 reserve verification report, the equivalent alkaline metals contents of Kaiyuan core samples is between 0.38% to 0.95% (K + Na), which is classified as a medium level for samples from Seams B7, 8, and 16 and as a high level in samples from Seams B9, 13 to 15, 17 to 18.

13.2.5.3 Coal Conversion Testing
Preliminary coal gasification testing was conducted on Kaiyuan core samples as reported in the 2018 reservation verification report. The core samples present the following properties. Further testwork is required to confirm the gasification properties.
- Medium to high resistance to breakage of the larger sizes of coal samples (>25 mm);
- Low to medium thermal stability;
- Weak slagging tendencies;
- High reactivity with CO2.
13.2.6 Other Properties
Other test work reported in the 2018 reserve verification report include
the determinations of (1) the concentration of the humic acids, (2) grindability, and (3) the liability of materials associated with coal seams to breakdown on agitation in water (Andreasen Pipette Sedimentation Tests). The major results are summarized as follows:
- Low content of humic acids with an average between 3.4% to 8.1%;
- Ease for grinding with an average Hardgrove grindability index (HGI) 85 to 90;
- Long settlement time from 5 to 24 hours with no sieving data reported.
13.3 Processing Properties
13.3.1 Physical Properties
Both the true and apparent densities were determined for coal samples.
The average of the true density of the coal samples is between 1.49 and 1.64 g/cm3; the apparent density average is between 1.30 and 1.43 g/cm3. The true density is the mass divided by the volume occupied by the actual, pore-free solid in coal. The apparent density of coal is the mass divided by the overall sample volume.

13.3.2 Coal Washing Ability Test
Screening tests as well as float-sink tests were carried out using Kaiyuan drill core samples and pit samples from the Beishan Mine and Heishantou Mine. The test results are summarised as follows.
13.3.2.1 Kaiyuan Core Samples Washability Testing
Core samples from Seams B7, 9, 13 and 14 were collected for screening and float-sink testing. Screening was conducted at 0.5 mm, 3 mm, 6 mm, and 13 mm, and float-sink testing was carried out on the combined materials coarser than 0.5 mm. The screening test results are shown in Table 13.9. The overall ash content of each core sample is from 3.9% to 11.9% on a dry basis, which meets the minimum thermal coal ash quality as defined in local regulations (< 40% Ash, dry).

Assuming the float clean coal product has an ash content of 10.0% or less dry, no processing will be required for the Seams 7, 9 and 13 due to the low head ash content levels of up to 8.6% dry. For Seam 14, as shown in Figure 13.1, theoretically a gravity separation at a SG of 1.65 will produce over 90% clean coal yield with a dry basis ash of 10.0%. In this case, the near gravity material (+/-0.1 SG) is approximately 10% that indicates a low theoretical degree of separation difficulty based on Chinese criteria.

The Beishan Coal Mine is located to the west of the Property.
Beishan pit samples from Seams B7 and B9 were collected and tested for size distribution and washability to simulate Kaiyuan coal properties. The combined raw coal sample has a very low ash of 5.4%, dry, that is typical for the coals mined in the area. The weight distribution and ash content of each size fraction are presented in Table 13.10. The results indicate that Beishan pit samples have a coarse size distribution with 58% larger than 300 mm. The in-situ fines (<0.5 mm) content is low at about 0.2% by weight. For the target utility industry market, coal processing is not required.

Notes: * Calculated ash content from each SG products
The average coal ash content of the fraction 50 to 0.5 mm is approximately 10.15% on a dry basis, which accounts for over 95% fraction of the overall samples (50 to 0 mm). About 50% of the coal was between 50 and 25 mm with an average ash content of 10.7%, dry. The washability curves based on the Heishantou data are presented in Figure 13.2. At a separation SG of 1.5, the theoretical clean coal ash is about 5.87% dry, with a clean coal theoretical yield of 94%. The resulting near gravity material content is less than 4.4%, which indicates a simple gravity separation method can effectively separate clean coal from gangue materials.

However, for the target coal market in the utility industry, the raw coal samples from Heishantou can meet the quality requirements without any treatment. This can be concluded from the low ash content in Table 13.11, as well as the high calorific values and low sulphur content. The gross calorific value was measured as 27 MJ/kg for raw coal samples larger than 50 mm and 26 MJ/kg for coal samples less than 50 mm. The total sulphur content is about 0.5% and 0.8% on a dry basis for the >50 mm and the < 50 mm raw coal samples, respectively.
13.4 Major Characteristics of Kaiyuan Weathering Coal
Humic acids were identified from the weathered zone of the Kaiyuan coal seams as reported in the 2018 and 2020 reserve verification reports. The average content of humic acids is approximately 39.7% which is classified as medium hnumic acid coal according to the local regulations. The potential economic values of the weathered coals have been discussed in the 2018 PEA and 2019 FS reports.

14 MINERAL RESOURCE ESTIMATES
14.1 Introduction
PVMA has carried out an estimate of coal resources within the southern (expansion area) portion of the Property on the basis of drillhole data provided by Kaiyuan. The data included drillhole collar locations, depth of coal seams, surface topography as of September 2019, and ash content (Ad%), moisture (Mad%), volatile content (Vadf), and net calorific value of dry coal (Qnet, d (MJ/Kg)). Geological strip logs were available for several of the drillholes but most collar, seam depth and thickness information was extracted from information plotted on geological long sections through the Property. Coal quality data were obtained from the 2019 resource verification report.
14.2 Drillhole Data
Location, coal seam interval and quality data were obtained for 42 drillholes (Figure 14.1). Only the 26 holes inside the Property boundary were used to estimate the quantity of coal.
Figure 14.1 Kaiyuan Drillholes
The dataset also includes 191 coal seam intercepts of which 115 are located within the boundaries of the mining licence. Of the 332 coal quality analyses, 221 are located within the boundaries of the mining licence.
The coal seams were modelled in the basis of the documented top and bottom intercepts. All coal intercepts were assigned an indicator value of one (1) and all waste had a value of minus one (-1). Because the coal quality intervals do not always match exactly with the intervals determined for the coal seams, the volumes of the modelled seams were estimated first and then the coal quality parameters were estimated for those modelled volumes.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
14.3 Composites
The intersected thickness of the coal seams was used in the construction of the resource model so there was no compositing of coal intercepts. The coal quality samples were composited to a thickness of three (3) meters which was the most common sample length in the dataset.
14.4 Bulk Density
Bulk density measurements were carried out on all nine major coal seams by the Xinjiang Bureau of Geology and Mineral Resources and reported in the 2018 Resource Verification Report. It is assumed that these measurements contain moisture. A bulk density value of 1.34 g/cm3 was used for the resource estimate.

14.5 Geological Interpretation
The Property contains nine (9) coal seams of potential economic interest. From oldest to youngest these are labelled B7, B8, B9, B13, B14, B15, B16, B17, and B18. All seams are essentially parallel, strike east-west, and dip approximately five (5) degrees to the south. All seams were modelled as south-dipping sheets using the vertical, intersected thicknesses from each of the drillholes located within the boundaries of the Property. Although the seams are more extensive than the limits of the Property, they have been modelled only to the limits of the Property because the Company is constrained to mine only within the boundaries of the Property and therefore the existence of any coal measures beyond those boundaries is irrelevant to the exercise of resource estimation.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
14.6 Measures of Spatial Continuity
The existence and identity of the seams are well documented in drillholes and, for seams B7 and B9, by mining in the active pit to the immediate north of the expansion area. Drillholes are spaced at north-south distances of 200 meters or less, on lines that are approximately 500 meters apart east-west. Further, some if not all, of the seams are being mined in adjacent mines to the immediate east and west of the Property. Therefore, there is a high level of confidence in the continuity of seams within the Property and it was considered unnecessary to assess spatial continuity of the seams by variographic analysis because of the abundance of evidence of spatial continuity. Instead, a search ellipse was constructed with a diameter of 500 meters, thickness of 50 meters, and a south dip of five degrees. The size ensured that the ellipse would capture holes on two adjacent north-south lines and the dip ensured that the ellipse would honour the dip of the seams.
The coal quality estimates were obtained by inverse distance squared (ID2) interpolation using a search ellipse measuring 800 meters north-south by 600 meters east-west, by 10 meters vertical, with a dip of five (5) degrees to the south.

14.8 Interpolation Plan
The coal indicator (value of 1) was interpolated into the blocks in a single
pass. In order for a value to be interpolated into a block it was necessary that a minimum of two (2) and a maximum of four (4) intercepts be located within the volume of the search ellipse. As each seam in each drillhole was represented by a single indicator, the minimum requirement of two intercepts means that each block was informed by a minimum of two drillholes.
Coal quality was interpolated in a single pass using inverse distance squared (ID2) weighting. In order for a value to be interpolated into a block it was necessary that a minimum of one (1) and a maximum of six (6) composites were located within the volume of the search ellipse.

14.9 Reasonable Prospects of Eventual Economic Extraction
Because at least some of the coal seams extend to surface and all of the seams will be exploited by open pit mining methods, it is necessary to constrain the resource estimate by a design pit that is based on reasonable cost and revenue values. A design, break-even pit was constructed using a current mining cost of RMB64 per tonne and a sales value of RMB140 per tonne. No cost was allocated for processing and mining dilution was assumed to be zero and mining recovery 100 percent. An overall pit slope of 38 degrees, the same as the current mining operation, was used to define the ultimate pit walls.
14.10 Mineral Resource Classification
Because drillholes are generally 200 meters or less apart on lines that are at most 500 meters apart, and the coal seams are exposed in active open pit mines on the east, north and west sides of the expansion area, there is very strong evidence for the continuity of the coal seams within the expansion area. For this reason, all resources have been classified as Indicated.
14.11 Mineral Resource Tabulation
The pit-constrained resource estimate for the expansion area is set out in Table
14.3. The resource has been estimated from surface to 575 meters above sea level, the minimum elevation of the mining licence.

14.12 Block Model Validation
The block model was validated by visually checking that the wireframes honour the coal seam intercepts in the drillholes, that the wireframes do not project above the topographic surface, and that the blocks in the model are constrained by the wireframes. No discrepancies were noted.
14.13 Comparison With Previous Estimates
In 2018, the 9th Brigade of the Xinjiang Geological and Mineral Bureau completed a resource estimate for the expansion area. The resources were classified as 331, 332, and 333, the Chinese resource classification categories that are approximately equivalent to the measured, indicated and inferred categories used by JORC and other western resource classification systems, and included 68.5 million tonnes in the 331 category, 36.2 million tonnes in the 332 category and 16.2 million tonnes in the 333 category. This estimate was not constrained by a design pit nor by the minimum elevation of the mining licence and extends to the full limits of the licence within the expansion area.
The 331 resources are largely confined to seams 7 and 9, with the exception of the southwest portion of the licence area where drillholes were not as closely spaced as elsewhere and where resources were classified as 332. Resources in seams 8, 15, 16, 17 and 18 were classified as 333. Therefore, the two estimates are not directly comparable although the 331 resource of 68.5 million tonnes is similar to the current resource estimate of 61.8 million tonnes and both estimates largely cover the same portion of the resource.
15 MINERAL RESERVE ESTIMATES
The mineral reserve estimate described in this section is based on the resource model detailed in Section 14 of this Report. The coal resources used in this report are based on the Indicated resource category. This CPR is considered to be of the level a Pre-Feasibility Study (PFS) report and is based on a 0.9 million tonnes per annum production rate as per mining license and the 2019 Feasibility Study (FS) report. The 'safety production permit' allows for production to be carried out at 1.2 million tonnes per annum and Nan Nan has authorized the author (Loschiavo) to scale up the mine plan to
1.2 million tonne production rate on the basis of the original 0.9 million tonnes per annum FS. The final design and mine plan are therefore the work of this author work and are considered to be reasonable for the Kaiyuan Coal mine.

15.1 Summary Coal Reserves
The summary of open pit coal reserves are shown in Table 15.1. Note that the coal reserves are rounded up to nearest 100,000 and above elevation 575 as per mining licence. The reserves only are reported for the South region of the mining license. These reserves do not include the North region of the current active mining area.
Table 15.1 Kaiyuan Open Pit Coal Reserves
Coal Seams | Classification | Tonnes |
Total | Probable | 63,481,000 |
Source: PVMA (2020)
The reserves are all considered Probable as all the estimated resources are classified as Indicated. The accuracy of the reserve estimate is, in part, a function of the quality and quantity of available data and of engineering and geological interpretation and judgement. Given the data available at the time this report was prepared, the estimate presented herein is considered to be reasonable. However, the reserve estimate should be accepted with the understanding that possible additional data and analysis that might become available in the future may necessitate revision. These revisions may be material. There is no guarantee that all or any part of the estimated reserves may be recoverable. Mineral resources are not mineral reserves and there is no assurance that any additional mineral resource that is not already classified as reserves will ultimately be reclassified as proven or probable reserves. Mineral resources which are not mineral reserves do not demonstrate economic viability.
15.2 Basis for Mineral Reserves Estimate
The mineral reserves has been determined using costs set out in Table 15.2.
Table 15.2 Kaiyuan Coal Mine Operating Cost Summary Estimate
Parameters | Value |
Mining | CNY 58.46*/tonne coal |
Coal Preparation & General Administration | CNY 7.81/tonne coal |

Coal Price | CNY 140/tonne coal |
Coal Production Rate | 900,000 tpa |

- Operating Costs exclude amortization, depreciation and interest expense of 0.16, 9.49 & 0.5 CNY/t, respectively.
- II-79 -
APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
The mining, coal preparation and general administration costs are referenced from the 2019 FS. The mining costs are based on CNY per tonne coal, which equates to CNY9.90 per tonne of material using a 5.91:1 strip ratio. The basis for the mineral reserve estimate is used in the following Lerch-Grossman optimization. Also, the operating cost summary is based on a 900,000 tpa, which is conservative compared to the 1,200,000 tpa allowable coal release. Since there is a 33% increase in coal production, the operation should realize a lower operating cost over the life of mine.
15.2.1 Lerchs-Grossmann (LG) Pit Shell Optimization
A percentage block model developed for Section 14, was transferred into the Maptek VulcanTM software. A Lerch-Grossman (LG) Pit Shell optimization was conducted to validate the mineral reserve estimate. The parameters for the optimization used are set out in Table 15.2. A typical cross section of the LG Pit shell and coal seams is shown in Figure 15.1
Figure 15.1 Typical Cross-Section of LG Pit Shell and Coal Seams Outlines
Source: PVMA (2020)
The LG optimization shell resulted in a pit-constrained reserve of 69.5 million tonnes with an overall strip ratio of 5.44:1 (waste tonnes: coal tonnes). The reserves shown in Table 15.1 are constrained by the lower limit of the mining licence (525 masl) in addition to the pitshell and totalled 63.5 with an overall strip ratio of 5.91:1. Comparing the LG optimization shell with the pit design, the material difference in reserves is 9.5%, which reasonable for this type of estimate.

16.2.1 Hydrogeology
Minor quantities of ground water are present in the main coal layers. The climate is essentially dry. Water from precipitation (rain and/or snow) which will seep into the underlying ground will typically evaporate. Based on the hydrological conditions and the local climate, water drainage, collection and removal from the open pit are deemed acceptable as outline in the 2018 report.
16.3 Mine Design
The mine design is defined by the mining license issued by the Autonomous Region Foreign Trade and Economic Cooperation Bureau and the Industrial and Commercial Bureau of the Autonomous Region for an operation of 900,000 tonnes per year of coal mining. The Mining Licence is held by Mulei County Kaiyuan Coal Co. Ltd. (Kaiyuan) a wholly-owned subsidiary of Nan Nan Resources Enterprise Limited. The safety production permit allows for 1,200,000 tonnes per coal mining which is also held by Kaiyuan. The area designated for coal mining is indicated by the X and Y coordinates outlined in Table 4.1 (1980 Xi'an coordinate system) and is shown in Figure 4.2.
16.3.1 Mine Design Parameters
Mining will be carried out by stripping overburden and rock material down dip at a declining angle between 3 and 8 degrees to a maximum bench height of 10 meters to release the coal ore. The final mine design parameters are shown in Table 16.3 with a typical cross-section showing mining sequence shown in Figure 16.1.

16.3.2 Haul Ramp Design
The ramp design width follows the guidelines set out in China. The current design uses 45-tonne articulated haul trucks as the largest vehicle traveling on the ramp; the main road will be 20.0 meters wide with an 8% ramp grade.
16.3.3 Final Design and Phasing
The final design was completed by the author, which is required by JORC to determine reserves as shown in Figure 16.3. The design was completed to a lower elevation of 575 masl as per the mining license.
The phasing for the mine will be split into two main stripping phases. The current mining activity is in the north area of the mining lease (i.e: Existing mine area). The first mining phase will be in the middle of the mining lease and will operate over a period of approximately 24 years. The final phase, (Ercai District), in the south end of the mining lease will be mined over the next 29 years.
The first mining phase will be split into two sub-phased activity areas, the East and West, as shown in Figure 16.2. Also shown are the current mining activities, dumps and facility locations. Total mining activity will be over a mine life of 53 years plus one year of pre-stripping.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
The mine production schedule from the FS was based on 900,000 tonnes per year. The increase is due to the 'Safety Production Permit' allowing the coal output to increase to 1.2 million tonnes per year. During the period 2017 to 2019, coal output was 2.09, 2.08 and 1.441 million tonnes per year. Since there is no coal release in this latest production schedule during pre-production, this gives the mine significant time to allow stripping to be performed without coal release disturbance. Coal release will continue in the north portion of the mining lease during stripping.
The coal quality data presented in the annual mine plan is based on coal release presented in the year of mining and blended based on the seams that are exposed. The calorific values, volatile matter, moisture and ash content indicates that the coal falls within the limits of marketable coal, therefore requiring no washing. The coal preparation plant will be required as function of the coal contracts.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
To increase coal production to 1.2 million tonnes per year, adjustments to waste material removal had to be increased in the first seven years. Pre-stripping shows approximately 10 million tonnes of material in year 2022. During years 2023 to 2025, waste stripping increases to 8.8 million tonnes per annum, then reduces gradually during years 2026 to 2038 to approximately 6 million tonnes and 3 million tonnes, respectively. It then increases up to approximately 8 million tonnes from 2039 to 2042. Pre-stripping will also release approximately 1.2 million tonnes of coal ore in year 2023 and for the life-of-mine. The strip ratio will average 5.9 over the life-of-mine.
16.5 Waste Material Management Plan
Over the life of mine, the mine will produce approximately 374.9 million tonnes of waste rock and overburden material. The mine has two dumping locations; the internal in-pit dump located North of the First phase mining area and the Northern Outer (Beiwai) dump site located on the North side of the mining lease and outside of the pit (ex-pit), as shown in Figure 16.2.

16.7 Explosives
Overburden and rock stripping will require blasting which is managed by the contractor.
Blast designs are based on 10-m benches and 1-msub-drill, using a powder factor of approximately 0.33 kg/m3 for rock and 0.22 for coal kg/m3. Over the life of mine, the project will use approximately 1.1 million kg per year of bulk ammonia-nitrate and fuel-oil explosive. The project will use conventional blasting products: non-electric detonating cords, delays and boosters. Blasting considerations of explosive timing and quantity of down-the-hole product will be adjusted for blasting near facilities.
16.8 Mine Personnel
Management staff will be owner-represented and will comprise 11 personnel. Personnel was increased to accommodate the 1.2 million tonnes per year coal production and will be comprised of 232 production staff, 9 service personnel, 9 other personnel, 6 safety personnel and 6 outsourcing staff, totalling 259 mine workers.
16.9 Mine Fuel
Over the life of mine, the project will consume approximately 10.0 million liters of diesel fuel per year.
16.10 Competent Person's View

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
17.1 Kaiyuan Coal Previous Production and Quality
Production data for the period 2017 to 2019 inclusive are listed in Table 17.1. The fine coal product quality data are also presented in the same table. The ash content is low, in the range of 5.4% to 8.4% and the net heating values for the 2017 and 2018 data are higher than the required 18 MJ/kg. The lower heating value reported for 2019 relates to the mining of Seam XB2 which is of inferior quality but is nearly mined out. In addition, the alkaline elements potassium and sodium are high in the ash which will has a negative impact on combustion. Conventional coal preparation cannot remove these impurities.

17.2 Kaiyuan Coal Core Samples Quality Data 2018-2020
Kaiyuan coal is low rank bituminous. The tested coal core samples from the 2018 and 2020 sampling programs indicate that in general, Kaiyuan coal contains low ash as well as low concentrations of deleterious elements including total sulphur, phosphorous, fluorine and arsenic. Some core samples from Seam B9 have a chlorine content higher than the threshold level 0.3%, although most of the measurements are lower than this. The heating values of the core samples are high, in the range of 25.6 to 28.4 MJ/kg without processing. These properties indicate that the run-of-mine coal can meet thermal coal market requirements.
17.3 Raw Coal Quality of Nearby Coal Mines
Large samples collected from the nearby mines confirmed the low ash and sulphur content as well as the high heating value of the coal as seen from the coal washability test results of Heishantou and Beishan samples. The raw coal ash on a dry basis was reported as 5.4% and 10.2% for Beishan and Heishantou, respectively.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
18.3 Power Supply
To meet mining power requirements, Kaiyuan will use dual power supplies. One existing power supply is provided by the 35 kV Beishan transform station which is located about 13.8 km southeast of the Property. A 10 kV substation is installed at the mine site to distribute power. Additional power will be provided by the proposed 110 kV substation of the Jinneng Mine via a 4 km-long, 10 kV powerline. Three diesel generators are also available as emergency power supply at levels of 75 kW, 50 kW and 25 kW.
18.4 Water Supply
Limited ground water is available at the site because of local hydrology and arid climate. The highest daily water consumption was estimated to be 701 m3/d for the mining operation as well as potable and sanitation water uses. These needs will be met by using both reclaimed and fresh water.
- Reclaimed water will mainly from the treated pit water and wastewater. The estimated pit water is about 244 m3/d, which can be purified and used for dedusting. Treated wastewater was estimated to be about 190 m3/d which can be used for dedusting and production.
- The estimated fresh water will be 396 m3/d considering a 1.5 factor that will be provided via an existing 38 km-long water pipeline from Jijihu County to the mine site water reservoir with a capacity of 300 m3.
Fire water is stored in three water tanks including one existing fire water tank of 300 m3 in the south of the mine site, and two proposed tanks, each of 400 m3, in the north of the mine site.

20 ENVIRONMENTAL STUDIES, PERMITTING AND SOCIAL OR COMMUNITY IMPACT
Currently, appropriate environmental permits have been approved for Kaiyuan's operation by the Environmental Protection Bureau of Mulei County. The planned and implemented environmental protection measures can adequately satisfy the need for environmental protection.
The physical environment of the Kaiyuan open pit coal mine is flat Gobi terrain with few inhabitants. Surface elevations range from 670 to 720 m. Major environmental impacts of the mining activities by Kaiyuan include overburden removal, noise, dust, pit water, and wastewater generation during mining, and greenhouse gas discharge during transportation. These pollutants are prevented or mitigated with the following measures:
- Pit water and wastewater will be treated and reused on site for dedusting and other operation purposes. Two emergency water discharge ponds were proposed for pit water and wastewater.
- Raw coal and gauge materials are stored in silos to prevent dusting issues caused by outdoor storage.
- Dust collection systems will be installed in the silos, and in the screening plant to further capture coal dusts to meet the national standard (GB20426-2006).
Additional measures and recommendations were proposed in the feasibility study for Kaiyuan to implement the mine site environmental protection program, which mainly include:
- Noise control methodologies;
- A comprehensive site reclamation plan; and
- A long-term environmental monitoring program.
21 CAPITAL AND OPERATING COSTS
All capital and operating cost estimates are reported in Renminbi (CNY) unless stated otherwise. The author of this section of the ITR is Antonio Loschiavo. The capital and operating cost estimates are, in the author 's opinion, appropriate for a Pre-Feasibility Study (PFS) level of study and are reasonable for the Kaiyuan Coal mine. Note that the initial study was based on a production rate of 900,000 tonnes per year coal production as per the mining permit. The safety production permit allows coal production to increase to
1.2 million tonnes per tonne per year. The capital therefore has been updated by the author to reflect the purchase of additional equipment required to accommodate the 1.2 million tonnes per year production plan. Operating costs were not updated and therefore the use of the 900,000 tonne per year operating costs for the 1.2 million tonne per year operation should be result in lower costs is considered to be a conservative evaluation.

A sensitivity analysis was performed on the Base Case coal price of CNY140/t of ore cost scenarios to determine which factors most affected the Project post-tax economics for both NPV and IRR graphs. The analysis revealed that the project is most sensitive to coal price and operating cost, the project also shows the moderate level of sensitivity to capital and production rate.
22.5 Competent Person's View
It is this competent person view that the economic analysis is, in part, a function of the quality and quantity of available data and of engineering and geological interpretation and judgement. Given the data available at the time of this report was prepared, the estimate presented herein are considered adequate and reasonable for this level of study.

23 ADJACENT PROPERTIES
There are operating coal mines immediately to both the east and west of the Property, but it was not considered necessary to describe these mines as the coal resources within the Property are fully documented.
24 PROJECT RISK ASSESSMENT
Table 24.1 summarizes the risk assessment for major project components. There is only one risk that is regarded by PVMA as of high likelihood: the current mine closure that was imposed because of the delay in obtaining the approval of resumption application from the Production Safety Supervision and Administration Bureau of local government as a result of Coronavirus pandemic. This closure is temporary but of unknown duration so PVMA regards it as of moderate effect and because it is already in effect, is highly likely in likelihood of occurrence.
There are no geological or mining factors that are regarded as being of high risk. The deposit is well defined, and the anticipated mining operation is an extension of an existing mining operation so there should be very little risk of unexpected technical issues.
In common with most, if not all, mining projects, the economics of the Kaiyuan mine are sensitive to commodity price. Changes in the price of coal are impossible to predict and are dependent on many factors beyond the control of the Company. Regardless, a drop in the market price of coal could have a major impact on the viability of the mining operation.

25 INTERPRETATION AND CONCLUSIONS
25.1 Geology and Mineral Resources
The Property area is underlain by rocks of Lower to Middle Jurassic age. The oldest rocks encountered in drilling belong to the Lower Jurassic Sangonghe Formation. Rock types include grey-green siltstone, fine-grained sandstone, and argillaceous siltstone and are approximately 90 m thick. The Sangonghe Formation does not contain coal beds. Regionally, the Sangonghe Formation is described as being comprised of coarsening-upward cycles that represent multiple delta progradations along basin margins. The thin-bedded,fine-grained and well-sorted sandstones with wide lateral extent are indicative of wave-dominated delta systems. Adjacent to the Property, the Sangonghe Formation contains conglomerate beds which may be indicative of fluvial channels.
The Sangonghe Formation is conformably overlain by the Xishanyao Formation of Middle Jurassic age. The Xishanyao Formation is comprised of basal conglomerate and coarse sandstone, grey to light-grey siltstone, mudstone and sandstone with coal seams. The Formation has an average thickness of approximately 125 m and is nearly flat-lying, with dips of 3° to 5° to the south.
The Property contains nine (9) coal seams of potential economic interest. From oldest to youngest these are labelled B7, B8, B9, B13, B14, B15, B16, B17, and B18, and they have an aggregate thickness of approximately 50 m. (Table 25.1) All seams are contained within the Middle Jurassic-age Xishanyao Formation and are essentially parallel, strike east-west, and dip approximately five (5) degrees to the south.
Seams B7 and B9 are the most continuous; seam B8, between B7 and B9, is restricted to the southern part of the expansion area. The remaining seams are generally continuous, but because they dip to the south, are progressively truncated to the north.

25.2 Mining and Mineral Reserves
A Lerch-Grossman (LG) Pit Shell optimization was conducted to validate the mineral reserve estimate. The parameters for the optimization used are set out in Table 25.3.
The LG optimization shell resulted in a pit-constrained reserve of 69.5 million tonnes with an overall strip ratio of 5.44:1 (waste tonnes: coal tonnes). The reserves shown in Tables 1.8 and 1.10 are constrained by the lower limit of the mining licence (525 masl) in addition to the pitshell and total 63.5 million tonnes with an overall strip ratio of 5.91:1. Dilution factor of 0.5% and Mining Losses average 5.4%. These are reasonable for this type of estimate.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
- Mineral Processing and Metallurgical Testing
- Based on the results from recent testwork programs, Kaiyuan coal is characterized as a low-rank bituminous, with no coking abilities, and is classified as non-coking coal BN31 according to the Chinese classification system. This is equivalent to the Subbituminous B coal class according to the American Society for Testing Materials (ASTM D-388).
- Kaiyuan coal is low in ash with stable moisture content and volatile matter, especially for the major coal seams B7, B9, B13 and B14. The average ash content for these seams is in a range of 7.0% to 17.5% on a dry basis.
- Kaiyuan coal has low concentrations of deleterious elements of S, P, F and As. Some samples from Seam B9 and B9 have a chlorine content of more than 0.3%. Kaiyuan float samples have a lower sulphur content and the distribution of P is consistent.
- Kaiyuan coal can be used as thermal coal. However, the high concentration of alkali elements will impact fusibility and cause slagging during combustion. Kaiyuan coal shows no coking properties. It may be used for coal gasification.
- Washability tests indicate that Kaiyuan coal has a low degree of separation difficulty in theory based on Chinese criteria. Other washability tests on raw coal samples from nearby coal mines confirmed this observation.
- Medium levels of humic acids were identified from the weathered zones of Kaiyuan coal seams as reported in the 2018 and 2020 reserve verification reports. The potential economic values of the weathered coals have been discussed in the 2018 PEA and 2019 FS reports.
- Recovery Methods
- Kaiyuan Coal mine has been in operation since 2008, producing as-mined coal which is screened to various sizes for the local thermal coal market. PVMA reviewed production data for the period 2017 to 2019, quality data of recent coal core samples, the operation of nearby coal mines op, and a coal quality projection by PVMA. It was concluded that the as-mined raw coal meets the quality requirements during the life of mine.
- II-119 -
APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
- Project Infrastructure
- The Kaiyuan coal mine is an open pit operation with auxiliary facilities and is well located with easy access to provincial roads and highways.
- Auxiliary facilities including maintenance shop, office building, and dormitories are currently located in the south of the mine site but will be relocated to the north-east during the expansion. A new screening plant has been constructed on site and is also located in the same area.
- Kaiyuan will use two power supplies. Existing power is provided by the 35 kV Beishan transformer station. A second power supply will be provided by the proposed 110 kV substation of the Jinneng Mine via a 4 km-long, 10 kV powerline. Three diesel generators are also available as emergency power supply.
- The site highest daily water consumption was estimated to be 701 m3/d for mine operations, potable and sanitation water uses and will be provided by using both reclaimed and fresh water.
- Market Studies and Contracts
Kaiyuan has an established thermal coal sales market with a low risk of future sale considering the local economy. Kaiyuan as-mined coal is screened to various sizes and sold on a ROM basis to the local thermal coal market.
25.7 Environmental Studies, Permitting and Social Impacts
Currently, appropriate environmental permits have been approved for Kaiyuan's operation by the Environmental Protection Bureau of Mulei County. The planned and implemented environmental protection measures can adequately satisfy the need for environmental protection.
25.8 Economic Analysis
All values are reported in Renminbi (CNY). The initial study was based on 900,000 tonnes per year coal production as per the mining permit. The safety production permit allows coal production to increase to 1.2 million tonnes per tonne per year. The economic analysis has been updated by the author to reflect additional equipment purchases necessary to accommodate the 1.2 million tonnes per year production plan. Operating costs were not updated and should be realized at lower cost and therefore the 900,000 tonnes per day operating costs is used as a conservative evaluation. Table 25.5 shows the economic analysis summary.

Notes: CNY are reported to the nearest thousand
The assumptions used in the financial estimate are based on an annual coal production rate of 1.2 million tonnes per year and a selling price of 140 yuan/metric ton of coal. Contingency and working capital is estimated at CNY11.644 million and 4.433 million which is approximately 3.1% and 1.2% and of total capital, respectively.
The feasibility study before-tax,after-tax cash flow and tax forecast is shown in Figure 1.7. As the cashflow model is completed over a twenty-year operation and the Life-of-Mine is over 54 years, the discounted cash flow model has little impact on the Net Present Value (NPV) after twenty years.

25.9 Risk Assessment
The only project risk that is regarded as currently significant is the current mine closure that was imposed because of the delay in obtaining the approval of resumption application from the Production Safety Supervision and Administration Bureau of local government as a result of coronavirus pandemic. This closure is of unknown duration and if persistent, may delay the mine development schedule as planned.
26 RECOMMENDATIONS
-
Geology and Mineral Resources
There are no recommendations for Geology and Mineral Resources. - Mining and Mineral Reserves
The only recommendation for mining is the completion of waste dump designs for the inner and outer waste dumps within the next five years or at the time of the next update of the feasibility study.
- Metallurgy and Processing/Recovery Methods
- Kaiyuan coal contains low ash, low sulphur, and high heating values, which is good for the thermal coal market. Other potential markets including coal gasification should be investigated.
- Available information indicates that coal washing is not required. However, it is recommended to conduct a trade-off study to evaluate the benefits of producing washed coal especially when mining coal seams with relatively high ash content in future.
- Determination of mercury is recommended for Kaiyuan coal.
- Environmental Studies, Permitting and Social Impacts
- A long-term environmental protection program should be in place to continuously monitor the pit water and wastewater treatment systems, air condition and soil quality at the mine site.

28 APPENDIX 1: VALUATION REPORT
Introduction
We have conducted a valuation of a mining right of 30 years (the "Mining Right" or the "Intangible Asset") of an open pit coal mine ("Kaiyuan Coal Mine") situated at Zhundong Economic and Technological Development Zone, Xinjiang, the People's Republic of China (the "PRC") as at 31 March 2020 (the "Valuation Date").
Purpose of Valuation
This report is being prepared solely for the use of the directors and management (the "Management") of Nan Nan Resources Enterprise Limited (the "Company"). The Company is listed on the Main Board of The Stock Exchange of Hong Kong Limited ("SEHK"). This report is being prepared for incorporation into the circular of the Company in relation to the acquisition (the "Acquisition") of the Mining Right. This report describes the basis of valuation, valuation methodologies considered and applied, our analysis, limiting conditions and presents our opinion of value.
We acknowledge that this report may be used by the Company as one of the sources of information for the Acquisition. The Acquisition is the result of negotiations between the transacting parties. The Management should be responsible for determining the consideration of the Acquisition, in which we are not involved in the negotiation and have no comment on the agreed consideration. We assume no responsibility whatsoever to any person other than the Management of the Company in respect of, or arising out of, the contents of this report. If others choose to rely in any way on the contents of this report they do so entirely on their own risk.
Statement of Compliance
This report is prepared in conformance with SEHK Listing Rules Chapter 18 and the Australasian Code for Public Reporting of Technical Assessments and Valuations of Mineral Assets, 2015 edition (the "VALMIN Code (2015)") prepared by the VALMIN Committee. The VALMIN Code (2015) provides a set of fundamental principles and supporting recommendations regarding good professional practice to assist the preparation of the valuation of mineral assets. This report is also based on accepted valuation procedures and practices that rely substantially on the use of numerous assumptions and consideration of various factors that are relevant to the operation of the Company.
- II-125 -
APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
Basis of Value
The basis of value is a statement of the fundamental measurement assumptions of a valuation. The VALMIN Code primarily uses the terms Market Value and Technical Value.
According to VALMIN Code (2015), Market Value is defined to mean "the estimated amount (or the cash equivalent of some other consideration) for which the mineral asset should exchange on the date of valuation between a willing buyer and a willing seller in an arm's length transaction after appropriate marketing where the parties had each acted knowledgeably, prudently and without compulsion."
According to VALMIN Code (2015), Technical Value is defined to mean "an assessment of a mineral asset's future net economic benefit at the valuation date, under a set of assumptions deemed most appropriate by a practitioner, excluding any premium or discount to account for market considerations."
The basis of value used in this report is the Technical Value. Market Value is not used because Market Value also does not specifically reflect the projected economic benefits attributable to the Company derived from the Mining Right. The Technical Value is more representative of the value because the Company has been principally engaged in the coal mine business and the value of the Mining Right is expected to be recovered from the operations of Kaiyuan Coal Mine will be placed into production in the near term in accordance with the production plan as advised by the Management.
Sources of Information
In the course of our valuation, we have had discussion with the Management on the Mining Right and the development of Kaiyuan Coal Mine. We have also relied on the following major documents and information in the valuation analysis. Some of the information and materials are furnished by the Management. Other information is extracted from public sources such as government sources, Thomson Reuters, Duff & Phelps LLC, etc.
The major documents and information include the following:
- Exploration Report "木壘縣凱源煤炭有限責任公司凱源露天煤礦及配套選 煤廠初步設計(修改)" dated April 2020 (the "Exploration Report");
- Relevant copies of permit(s) and license(s) in relation to Kaiyuan Coal Mine;
- Circular(s) and/or announcement(s) made by the Company in relation to the acquisition and the development of Kaiyuan Coal Mine;
- Projections of Kaiyuan Coal Mine prepared by the Management; and
- Industry and economic data.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
General Valuation Approaches and Methods
In conducting the valuation, we have considered three generally accepted approaches to obtain the value of a mineral project:
- Market Approach
- Cost Approach; and
- Income Approach.
Under each approach, a number of methods are available which can be used to assess the value of a subject. Each method uses a specific procedure to determine the value.
Market Approach
The Market Approach values an intangible asset by comparison of the prices at which other similar intangible assets or interests changed hands in arm's length transactions. The underlying theory of this approach is that one would not pay more than one would have to pay for an equally desirable alternative. By adopting this approach, we will first look for an indication of value from the prices of other similar intangible assets that were sold recently.
The right transactions employed in analyzing for indications of value need to be sold at an arm's length basis, assuming that the buyers and sellers are well informed and have no special motivations or compulsions to buy or to sell.
Where evidence of prices is available, it will often be necessary to make adjustments to these to reflect differences between the subject asset and those involved in the transactions.
Cost Approach
The Cost Approach values an intangible asset by using the historical cost which relates to the actual cost to create or develop an intangible asset. There are two fundamental types of cost quantified in Cost Approach valuation methods: reproduction cost and replacement cost. At the inception of the cost approach analysis, we decide which type of cost will be estimated and will be used.
Reproduction cost is the estimated cost to construct, at current prices as of the date of the analysis, an exact duplicate or replica of the subject intangible asset, using the same production standards, design, layout and quality of workmanship as the subject intangible asset. The reproduction intangible asset will include the same inadequacies, super adequacies, and obsolescence as the subject intangible asset.
- II-127 -
APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
Replacement cost is the estimated cost to construct, at current prices as of the date of the analysis, an intangible asset with equivalent utility to the subject intangible asset, using modern materials, production standards, design, layout and quality of workmanship. The replacement intangible asset will exclude all curable inadequacies, super adequacies and obsolescence that are present in the subject intangible asset.
Income Approach
The Income Approach focuses on the economic benefits generated by the income producing capability of an intangible asset. The underlying theory of this approach is that the value of an intangible asset can be measured by the present worth of the economic benefits to be received over the useful life of the intangible asset.
Based on this valuation principle, the Income Approach estimates the future economic benefits and discounts these benefits to its present value using a discount rate appropriate for the risks associated with realizing those benefits.
Alternatively, this can be calculated by capitalizing the economic benefits to be received in the next period at an appropriate capitalization rate. This is subject to the assumption that the intangible asset will continue to maintain stable economic benefits and growth rate.
The principal valuation methods under the Income Approach used in the valuation of intangible assets are:
- relief-from-royaltymethod;
- with-and-withoutmethod;
- excess earnings method; and
- greenfield method.
Valuation Approach
In the process of valuing the Mining Right, we have considered its nature and discussed with the Management on its effect and benefits to the business. Given the nature of the valuation subject and the development status of the business project, it would be appropriate and reasonable to adopt the Income Approach to value the Mining Right. The excess earnings method determines the value of an intangible asset as the present value of the cash flows attributable to the subject intangible asset after excluding the proportion of cash flows that are attributable to other contributory assets.
- II-128 -
APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
The Market Approach is not appropriate as there is not enough publicly available information on recent transactions comparable to the Mining Right of Kaiyuan Coal Mine and also does not precisely reflect the projected economic benefits specifically attributable to the Company derived from the Mining Right. The Cost Approach is not appropriate as it ignores the future economic benefits of the Intangible Asset. We have therefore solely relied on the Income Approach in determining our opinion of value.
We have derived a discount cash flow (DCF) valuation of Kaiyuan Coal Mine based on the net profit value (NPV) of the pre-debt,post-tax discounted cash flows with production projected for approximately 29 years commencing from 31 March 2022 to 31 August 2049. The model is expressed in real terms and is based on financial years ending 31 March. The financial model has been prepared with due regard to the Exploration Report and the production schedule for Kaiyuan Coal Mine as advised by the Company.
In this valuation, identified contributory assets include the fixed assets, the assembled workforce and the non-cash working capital.

Valuation Analysis
Existing Status of Kaiyuan Coal Mine
No production activities had been carried out on Kaiyuan Coal Mine as at the Valuation Date.
Mine Design
As advised by the Management, Kaiyuan Coal Mine is designed to be an open pit mine with a full mining capacity of 1.2 million tonnes of coal per annum.
Dilution factor and mining losses average are estimated to be 0.5% and 5.4% respectively. Excavators will be used for exploitation and dumping. The coal extracted will be stored on-site temporarily before selling to customers.
Production Schedule
The cash flow projections are based on the production schedule represented by the Management. Kaiyuan Coal Mine will require approximately 2 years to complete all necessary construction and commissioning work for the mine, and thus the development is expected to be completed by March 2022. It is expected that Kaiyuan Coal Mine will achieve its full mining capacity at 1.2 million tonnes per annum in the financial year ending 31 March 2022.
Coal Price and Revenue
Pursuant to the Exploration Report, the coal price is estimated to be approximately RMB140 per tonne during the projection period. Based on the mining output of 1.2 million tonnes per annum, revenue generated from Kaiyuan Coal Mine is approximately RMB168 million per annum at full mining capacity.
Production Costs
The unit production cost is estimated to be approximately RMB68.61 per tonne of coal inclusive of mining operating cost (RMB58.46/t) depreciation (RMB9.49/t), amortization (RMB0.16/t) and interest (RMB0.5/t). As advised by the Management, no processing is required for the production of coal and therefore relevant processing costs will not be incurred.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
Capital Expenditure
The total capital expenditure for the development of Kaiyuan Coal Mine is approximately RMB373.7 million, which is mainly employed for the development mine construction, civil engineering, equipment, installation and others.
Income Tax
We have adopted a tax rate of 25.0%, which is the corporate income tax rate of the PRC as at the Valuation Date.
Contributory Asset Charges
The contributory assets to the Mining Right include fixed assets, assemble workforce and working capital with after-tax contributory asset charges of approximately 10.20%, 9.15% and 5.52% as at the Valuation Date respectively, the basis of each are tabulated as follows:
Fixed assets | = Average of cost of equity and the cost of debt as |
referenced to the benchmark short term borrowing | |
rate quoted by the People's Bank of China | |
Assemble | = Intangible asset discount rate |
workforce | |
Working capital | = Cost of debt |
Resources Tax
Pursuant to the Exploration Report, the statutory resources tax is 6% of revenue.
Non-cash Working Capital Requirement
By referring to research performed by Aswath Damodaran, the non-cash working capital to sale of the mining industry is estimated to be approximately 13.64%.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
Discount Rate
To adopt the Income Approach, we must first obtain the weighted average cost of capital ("WACC") of the Company operating Kaiyuan Coal Mine as a basic discount rate. It is the minimum required return that a valuation subject must earn to satisfy its various capital providers including shareholders and debtholders. The WACC is calculated taking into account the relative weights of each component of the capital structure. In the course of our analysis, we have applied other specific risk premiums to the WACC such that the discount rate adopted in our valuation follows the formula:
Discount rate | = We x Re + Wd x Rd x (1 - T) + Rs | |
in which | ||
Re | = | cost of equity |
Rd | = | cost of debt |
We | = portion of equity value to enterprise value | |
Wd | = portion of debt value to enterprise value | |
T | = | corporate tax rate |
Rs | = other specific risk premiums |
Cost of equity
From modern portfolio management perspective, typical investors are risk-averse and rational. They make all investment decisions based on risk and return of an investment opportunity. The cost of equity, therefore, should account for the risk premium, which is the required additional return over the risk free rate. Additional risk premiums such as country risk premium and size premium are added to reflect the other risk factors concerning the Company operating Kaiyuan Coal Mine. All the estimates are supported by public sources such as Thomson Reuters and Duff & Phelps, LLC. The capital asset pricing model ("CAPM") is used to determine the appropriate cost of equity of the Intangible Asset.
Cost of equity | = risk free rate + equity beta x market risk premium + |
size premium + country risk premium |
- II-135 -
APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
The CAPM states that the required return of an asset is based on the non-diversifiable risk, as represented by the beta, and the market return and the risk free rate. In estimating the beta, we have identified comparable companies based on the criteria that they are engaged in the coal mining industry in the PRC. The 22 comparable companies are listed as follows:

- Figures above are subject to rounding
Notes :
- This is the 10-year yield based on the United States Government Bond Benchmark Yield Curve, which is a mature market risk free rate.
- This is the adjusted beta by making reference to publicly listed companies with comparable business nature and operation, which are sourced from Thomson Reuters.
- Market risk premium = market rate of return - risk free rate. To derive a long-term, equity risk premium, we refer to the long-horizon expected equity risk premium for the United States (based on historical data), published by Duff & Phelps, LLC. A mature market equity risk premium is used since we derive a stable, long-term discount rate adopted in the valuation; therefore we have adopted the expected market return of the United States instead of one from developing equity markets. The country risk premium (in Note 5 below) reflects the expected operating location of the Company operating Kaiyuan Coal Mine.
- Based on the research published by Duff & Phelps, LLC, the CAPM does not fully account for the higher returns of smaller company stocks.
According to their research data of historical returns from 1926 - 2019 of micro-cap companies, the size premium (returns in excess of those predicted by CAPM) is 4.99%. - This is the increased risk with operating in the PRC, where the risk profile is different to the market premium applied in our analysis, including business risk, financial risk, liquidity risk, exchange rate risk & country risk. We refer to the data and methodology derived on Damodaran Online (http://pages.stern.nyu.edu/~adamodar/), updated for 2020, in determining the country risk premium for the Company operating Kaiyuan Coal Mine.
Damodaran Online is prepared by Aswath Damodaran, who is currently a Professor of Finance at the Stern School of Business at New York University. Mr. Damodaran has published several books, including four books on equity valuation and two on corporate finance. He has also published papers in the Journal of Financial and Quantitative Analysis, the Journal of Finance, the Journal of Financial Economics and the Review of Financial Studies.

APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
Given the above variables, we have derived the cost of equity of 13.31%.
- Cost of debt
The cost of debt represents the estimated required return of debt financing for the Company operating Kaiyuan Coal Mine when borrowing or issuing debt (such as corporate bonds). As at the Valuation Date, the cost of debt, taking into account of the China Above 5 Years Benchmark Lending Rate was 4.90%.
- Weight of debt
To stay competitive in the industry, it is reasonable to assume that the Company should achieve a debt level toward the average of the weight of debt of its industry comparables. Through the analysis of the industry comparables, the weight of debt is estimated as 42%.
-
Weight of equity
The weight of equity is estimated as 58% by adopting the same basis as above. - Other specific risk premiums
We have applied a 2.0% specific risk premium to reflect the specific risk of Kaiyuan Coal Mine.
A further 1.0% intangible asset risk premium is added to reflect the higher risk of the Intangible Asset which has higher risk compared to other assets held by comparable companies such as fixed assets and monetary assets, the appropriate discount rate should be higher than the WACC.
Based our foregoing analysis, the nominal discount rate adopted for the valuation of the Intangible Asset as at the Valuation Date is illustrated as follows:
Discount rate | = 58% x 13.31% + 42% x 4.90% x (1 - 25.0%) + 2% + 1% |
- 12.23%
* Figures above are subject to rounding
Since the revenue and cost projections are estimated as at the Valuation Date, without projected future inflation, the resulting cash flows are stated in real terms. Therefore, we have adjusted the nominal discount rate for inflation to determine the real discount rate.
We have estimated an inflation rate of 2.83% based on the average China inflation rate projected by the International Monetary Fund.
Based on the nominal discount rate of 12.23% and the inflation rate of 2.83%, the estimated real discount rate is 9.15% which is applied to real ungeared after tax cash flows.

Geological characteristics: Seams of black to brown coal hosted by clastic sedimentary rocks. The coal is banded dull and bright and generally hard. The texture of the original vegetation is sometimes partially preserved.
Tectonic setting: Stable continental basins; shelves on the trailing edge of continents; foreland basins; back-arc basins.
Depositional environment: An area of slow sedimentation in fresh water with few or no marine incursions, most commonly a river delta; shoreline swamp; raised swamp; lake; floating vegetation mats.
Age of mineralization: Often Tertiary but can be older.
Host/Associated rock types: Sedimentary rocks exhibiting evidence of non-marine deposition. Carbonaceous mudstones, siltstones and sandstones are the most common, commonly with cross-stratification and other shallow-water sedimentary structures.
- II-145 -
APPENDIX II | COMPETENT PERSON'S REPORT AND VALUATION REPORT |
Criteria | JORC Code explanation | Commentary |
Deposit form: Coal seams generally conform with regional bedding; sometimes seams are deposited in areas of local subsidence, such as fault-controlled blocks or sink holes in karst topography, in which case deposits may be lens shaped. Occasionally seams can be thickened/deformed by surface slump, glacial drift or faulting. Seams may pinch out or split on a local or regional scale.
Texture/Structure: Sub-bituminous coal is usually composed mostly of clarain and vitrain. Footwall sediments are commonly penetrated by roots or weathered to clay.
Coal seams/Associated mineral matter: Sub-bituminous coal can contain up to 30 % moisture. It usually contains a high proportion of vitrinite and lesser amounts of fusinite and liptinite. Mineral matter is in the coal as rock bands, as finely intermixed material of authogenic or detrital origin and as secondary material deposited in fractures and open spaces. Authogenic mineral matter includes pyrite, siderite and kaolinite.
Weathering: Weathering of sub-bituminous coal reduces the calorific value by oxidizing the carbon-hydrogen complexes. Minerals in the mineral matter will also oxidize. Pyrite oxidizes to sulphates. Secondary carbonates are formed.

of the Property. Although the seams are more | ||
extensive than the limits of the Property, they | ||
have been modelled only to the limits of the | ||

Because at least some of the coal seams extend to surface and all of the seams will be exploited by open pit mining methods, it is necessary to constrain the resource estimate by a design pit that is based on reasonable cost and revenue values. A design, break-even pit was constructed using a current mining cost of RMB64 per tonne and a sales value of RMB140 per tonne. No cost was allocated for processing and mining dilution was assumed to be zero and mining recovery 100 percent. An overall pit slope of 38 degrees, the same as the current mining operation, was used to define the ultimate pit walls.
Because drillholes are generally 200 meters or less apart on lines that are at most 500 meters apart, and the coal seams are exposed in active open pit mines on the east, north and west sides of the expansion area, there is very strong evidence for the continuity of the coal seams within the expansion area. For this reason, all resources have been classified as Indicated.

In 2018, the 9th Brigade of the Xinjiang Geological and Mineral Bureau completed a resource estimate for the expansion area. The resources were classified as 331, 332, and 333, the Chinese resource classification categories that are approximately equivalent to the measured, indicated and inferred categories used by JORC and other western resource classification systems, and included 68.5 million tonnes in the 331 category, 36.2 million tonnes in the 332 category and 16.2 million tonnes in the 333 category. This estimate was not constrained by a design pit nor by the minimum elevation of the mining licence and extends to the full limits of the licence within the expansion area.
The 331 resources are largely confined to seams 7 and 9, with the exception of the southwest portion of the licence area where drillholes were not as closely spaced as elsewhere and where resources were classified as 332. Resources in seams 8, 15, 16, 17 and 18 were classified as 333. Therefore, the two estimates are not directly comparable although the 331 resource of 68.5 million tonnes is similar to the current resource estimate of 61.8 million tonnes and both estimates largely cover the same portion of the resource.

The mining, coal preparation and general administration costs are referenced from the 2019 FS. The mining costs are based on CNY per tonne coal, which equates to CNY9.90 per tonne of material using a 5.91:1 strip ratio. The basis for the mineral reserve estimate is used in the following Lerch-Grossman optimization. Also, the operating cost summary is based on a 900,000 tpa, which is conservative compared to the 1,200,000 tpa allowable coal release. Since there is a 33% increase in coal production, the operation should realize a lower operating cost over the life of mine.

Currently, appropriate environmental permits have been approved for Kaiyuan's operation by the Environmental Protection Bureau of Mulei County. The planned and implemented environmental protection measures can adequately satisfy the need for environmental protection.
The physical environment of the Kaiyuan open pit coal mine is flat Gobi terrain with few inhabitants. Surface elevations range from
670 to 720 m. Major environmental impacts of the mining activities by Kaiyuan include overburden removal, noise, dust, pit water, and wastewater generation during mining, and greenhouse gas discharge during transportation. These pollutants are prevented or mitigated with the following measures:
- Pit water and wastewater will be treated and reused on site for dedusting and other operation purposes. Two emergency water discharge ponds were proposed for pit water and wastewater.
- Raw coal and gauge materials are stored in silos to prevent dusting issues caused by outdoor storage.
- Dust collection systems will be installed in the silos, and in the screening plant to further capture coal dusts to meet the national standard (GB20426-2006).

The LG optimization shell resulted in a pit-constrained reserve of 69.5 million tonnes with an overall strip ratio of 5.44:1 (waste tonnes:coal tonnes). The reserves shown in Table 15.1 are constrained by the lower limit of the mining licence (525 masl) in addition to the pitshell and totalled 63.5 with an overall strip ratio of 5.91:1. Comparing the LG optimization shell with the pit design, the material difference in reserves is 9.5%, which reasonable for this type of estimate.
No cut-off calculation is required.

The design and planning outlined for the Kaiyuan Coal is based on the resource model detailed in Section 14 of this Report. The coal resources used in this report are based on Indicated resources for the southern portion of the mining lease. This CPR is considered to be of the level of a Pre-Feasibility Study (PFS) report and is reasonable for the Kaiyuan Coal mine. The author of this section of the ITR is Antonio Loschiavo.

Currently, appropriate environmental permits have been approved for Kaiyuan's operation by the Environmental Protection Bureau of Mulei County. The planned and implemented environmental protection measures can adequately satisfy the need for environmental protection.
The physical environment of the Kaiyuan open pit coal mine is flat Gobi terrain with few inhabitants. Surface elevations range from
670 to 720 m. Major environmental impacts of the mining activities by Kaiyuan include overburden removal, noise, dust, pit water, and wastewater generation during mining, and greenhouse gas discharge during transportation. These pollutants are prevented or mitigated with the following measures:
- Pit water and wastewater will be treated and reused on site for dedusting and other operation purposes. Two emergency water discharge ponds were proposed for pit water and wastewater.
- Raw coal and gauge materials are stored in silos to prevent dusting issues caused by outdoor storage.
- Dust collection systems will be installed in the silos, and in the screening plant to further capture coal dusts to meet the national standard (GB20426-2006).

provided, or accessed. |
The Kaiyuan coal mine is currently in operation with an open pit production system and auxiliary facilities. The auxiliary facilities including maintenance shop, office building, and dormitories that are currently located in the south of the mine site, but which will be relocated to the north-east of the site during the planned expansion. The screening plant is also located in the north-east area.
The location provides easy access to provincial roads and highways. The major access road connecting the mine site to Provincial Road S327 is cement-concrete paved is approximately 7.0 m wide and 2.5 km long. Other site roads are gravel surfaced with a total length of over 6 km.
To meet mining power requirements, Kaiyuan will use dual power supplies. One existing power supply is provided by the 35 kV Beishan transform station which is located about 13.8 km southeast of the Property. A 10 kV substation is installed at the mine site to distribute power. Additional power will be provided by the proposed 110 kV substation of the Jinneng Mine via a 4 km-long, 10 kV powerline. Three diesel generators are also available as emergency power supply at levels of 75 kW, 50 kW and 25 kW.
Limited ground water is available at the site because of local hydrology and arid climate. The highest daily water consumption was estimated to be 701 m3/d for the mining operation as well as potable and sanitation water uses. These needs will be met by using both reclaimed and fresh water.

• Reclaimed water will mainly from the treated pit water and wastewater. The estimated pit water is about 244 m3/d, which can be purified and used for dedusting. Treated wastewater was estimated to be about 190 m3/d which can be used for dedusting and production.
• The estimated fresh water will be 396 m3/d considering a 1.5 factor that will be provided via an existing 38 km-long water pipeline from Jijihu County to the mine site water reservoir with a capacity of 300 m3.
Fire water is stored in three water tanks including one existing fire water tank of 300 m3 in the south of the mine site, and two proposed tanks, each of 400 m3, in the north of the mine site.
The ROM coal mined from the open pit will be trucked to a raw coal hopper and crushed to less than 300 mm. The crushed raw coal will be conveyed to a 12 m diameter raw coal silo with a capacity of 1,800 t. Coal from the raw coal silo will be fed via belt feeders to the screening plant to produce various sized products.
A new screening plant has been constructed on site to further classifying the crushed raw coal into different-size products.

All capital and operating cost estimates are reported in Renminbi (CNY) unless stated otherwise. The author of this section of the ITR is Antonio Loschiavo. The capital and operating cost estimates are, in the author's opinion, appropriate for a Pre-Feasibility Study (PFS) level of study and are reasonable for the Kaiyuan Coal mine. Note that the initial study was based on a production rate of 900,000 tonnes per year coal production as per the mining permit. The safety production permit allows coal production to increase to
1.2 million tonnes per tonne per year. The capital therefore has been updated by the author to reflect the purchase of additional equipment required to accommodate the 1.2 million tonnes per year production plan. Operating costs were not updated and therefore the use of the 900,000 tonne per year operating costs for the 1.2 million tonne per year operation should be result in lower costs is considered to be a conservative evaluation.
The capital cost estimate is summarized in the following table.

The following table summarizes the risk assessment for major project components. There is only one risk that is regarded by PVMA as of high likelyhood: the current mine closure that was imposed because of the delay in obtaining the approval of resumption application from the Production Safety Supervision and Administration Bureau of local government as a result of Coronavirus pandemic. This closure is temporary but of unknown duration so PVMA regards it as of moderate effect and because it is already in effect, is highly likely in likelihood of occurrence.
There are no geological or mining factors that are regarded as being of high risk. The deposit is well defined, and the anticipated mining operation is an extension of an existing mining operation so there should be very little risk of unexpected technical issues.
In common with most, if not all, mining projects, the economics of the Kaiyuan mine are sensitive to commodity price. Changes in the price of coal are impossible to predict and are dependent on many factors beyond the control of the Company. Regardless, a drop in the market price of coal could have a major impact on the viability of the mining operation.
