Black Swan Exploration
- Large electromagnetic (EM) anomaly consistent with Massive Sulphides detected beneath Black Swan open pit and previously mined Gosling deposit
- Drilling of the EM anomaly to commence immediately
Windarra Exploration
- Assays received from recent RC program at Windarra's Crazy Diamond Prospect; highlights
- PNRC0309 intersects 5m @ 0.75% Ni from 12m (ex- sulphides) including 1m @ 1.38% (approx. 0.8m true width)
- Anomalous gold mineralisation up to 0.5 g/t Au
Page 2
Poseidon Nickel (ASX: POS, "the Company") is pleased to announce the following updates:
- A 106% increase in the Silver Swan Ore Reserve Estimate following on from the increase in Mineral Resources (see ASX announcement "Silver Swan Resource Upgrade" released 5th August 2019).
- A large electromagnetic (EM) anomaly consistent with a massive sulphide EM response has been detected towards the base of the Black Swan mineralised sequence at depth below the open pit. An underground drill program to test the anomaly will commence immediately.
- Assay results from the scout drilling at Crazy Diamond (Windarra Project) have confirmed both nickel and gold mineralisation.
Commenting Mr David Riekie, Interim CEO said;
"This healthy Silver Swan Reserve upgrade is an important and significant benefit from the ongoing derisking and restart studies on and around Black Swan operations north of Kalgoorlie.
The EM anomaly identified below the Black Swan open pit and previously mined Gosling deposit, offers some very exciting potential and is a focal point for a priority drilling program.
Collectively, these outcomes are important additions that are building on the certainties created from previous successful drilling, to allow Reserve status and upgrade, as well as highlighting potential within previously untested zones. The proximity and location of the anomaly is an exciting prospect.
The additional and ongoing successful exploration also extends to our Windarra tenements."
Silver Swan Ore Reserve Estimate
The Silver Swan Ore Reserve has been updated based on Mineral Resource that was announced to market on 5th August 2019.
The Ore Reserve estimate, prepared by Mining Consultants, Entech Pty Ltd is based on the mining methods, designs, schedules, cost estimates and modifying factors, which have been determined from a revision of the previous Silver Swan and Black Swan 2018 Feasibility Study (refer announcement 18 July 2018). The outcomes have been achieved as part of the ongoing derisking and restart studies being undertaken for Black Swan.
The Ore Reserve economics are based on a processing recovery of 92.5% for nickel, commercial offtake terms and a nickel price of A$22,335/t. Copper and cobalt grades in concentrate do not reach assumed payable levels.
The existing Indicated Resources have been converted to Probable Ore Reserves subject to mining modifying factors. Any Inferred material contained within the mine plan has been treated as waste. All material has been assumed to be processed at the Black Swan processing plant located at the site, in conjunction with material mined from the Black Swan open pit and surface stockpiles.
The Ore Reserve estimate mine design is shown in Figure 1 and Figure 2.

Ore Reserve Estimate Statement
The Ore Reserve estimate for the Silver Swan ("SS") underground nickel mine as at February 2020 is 130,000 tonnes of ore grading 5.2% Ni for a total of 6,800 tonnes of contained Ni metal.
The final Ore Reserves summary is presented in Table A.

The Mineral Resource used as the basis for the Ore Reserve estimate was announced to market on 5th August 2019. Indicated Resources have been converted to Probable Ore Reserves subject to mine design physicals and an economic evaluation. No Measured material was contained in the Resource. Any Inferred material contained within the mine plan has been treated as host rock waste. The Ore Reserves have been defined at delivery to Black Swan processing plant, on the assumption that Silver Swan material will be processed alongside Black Swan open pit and surface stockpile material as detailed in the 2018 Feasibility Study.
The Ore Reserve estimate is based on financials and modifying factors determined as part of the 2018 Feasibility Study undertaken on the project. This statement relates to a global estimate.
Black Swan Exploration - Large Electromagnetic Anomaly Detected
A Downhole Electromagnetic (DHEM) survey has been conducted on PBSD002, a diamond hole drilled in 2019 sub-horizontally into the Black Swan deposit 900m below the Open Pit. The hole intersected disseminated to blebby nickel sulphides and provided the Company with an ideal DHEM platform to identify possible repeats similar to that of the Gosling Massive Sulphide Deposit (see Figure 3).
The DHEM survey managed and interpreted by Newexco, has resulted in a large, off-hole EM anomaly with a response consistent with massive sulphides. The anomaly is located 550m below and in the same stratigraphic location as the Gosling Massive Sulphide orebody. Gosling was mined in 2008 and produced 121,417 t @ 4.4 %Ni.
The DHEM anomaly is considered to be a high-priority drill target due to its basal contact location (stratigraphically favourable position to be nickeliferous) and the clean, late-time EM response which is consistent with massive sulphides at Black Swan and Silver Swan.
Page 5
Figure 3 - Location of DHEM anomaly with respect to the BSO workings
DHEM and Anomaly Details
PBSD002 intersected disseminated to blebby sulphides (289m @ 0.62%Ni, see ASX announcement "High Grade Nickel Intersections 27 May 2019). The DHEM survey utilized the DigiAtlantis probe on 5m to 10m stations and a 1km square surface loop with a base frequency of 0.5Hz.
The off-hole EM anomaly is located 450m down hole and 35m off to the west of PBSD002. The mineralisation intersected by the drilling is not in itself able to generate the highly conductive anomaly observed due to its disseminated sulphide nature.
A comparison of the Gosling EM response and the new anomaly by Newexco suggests that the source is larger and more conductive than historical EM surveys that found the Gosling deposit. Although this is at an early stage of interpretation this anomaly is interpreted to be caused by a highly conductive source that may be greater than the areal extent of Gosling.
Next Steps
A staged approach to the drilling will be adopted to assess the EM anomaly. Plans are currently being finalised as a priority to drill-test the modelled conductor plate to ascertain if the conductor composition is nickel sulphide.
Should the source of the anomaly contain nickel sulphides, a second hole will be drilled to ascertain the dip and width of mineralization.
The footwall parent hole will then be extended to 1000m depth and cased. This will allow for further DHEM surveying of the area of potential as highlighted in Figure 3. This program is anticipated to enable the majority of the zone of potential for massive sulphides between Gosling deposit and PBSD002 to be assessed.

Windarra Exploration - Crazy Diamond Prospect
The Company has received the assays from the recent RC program at the Crazy Diamond Prospect near Windarra where both gold and nickel have been intersected. The Crazy Diamond Prospect is the next komatiite channel to the north of Poseidon's Cerberus Discovery (69,000 Ni metal tonnes, see ASX announcement "Resource Increase of 25% at Windarra Nickel Project" released 1st December 2011).
While intersecting nickel mineralisation was a secondary aim of the stratigraphic drilling, PNRC0309 did strike nickel enrichment in a 5m zone 10m below surface. Inspection of the drill chips revealed that the nickel enrichment is closely associated with gossanous oxide blebs which are interpreted to be weathered sulphides near the basal contact of a large komatiite flow. Importantly Poseidon does not consider the intersection to be related to the weathering profile. This is further confirmed by the underlying geochemistry as presented in the Table 5 attachment where manganese, iron, copper, chrome and magnesium appear as expected from weathered ultramafic and sulphides rather than from lateritic enrichment.
Figure 4 - Windarra Nickel Project historical geochemistry and identified komatiite channels
Page 7
The intersection is interpreted to be at the base of the Upper Ultramafic, a subsequent komatiite flow to the Windarra Ultramafic (which hosts the Windarra, South Windarra and Cerberus Deposits). Poseidon's drilling to the north of the Cerberus Deposit in 2011 revealed minor sulphide nickel mineralisation in a similar stratigraphic position some 950m to the south of the recent intersection (referenced in Figure 5). Gossanous mineralisation had previously been uncovered in a trench 100m to the south of PNRC0309 however historical drilling by WMC and Poseidon under and around the gossan did not intersect anything further.
Figure 5 - Crazy Diamond Prospect and location of sulphide intercepts
Previous mapping had indicated that the basalt unit usually separating the Windarra and Upper Ultramafics elsewhere in the belt was 'missing' at Crazy Diamond, however due to the accumulation of sediments on the flood-plain, the Company could not ascertain the exact relationship between the two within the prospect. The drilling revealed that the Upper Ultramafic has indeed displaced the basalt in the stratigraphic sequence and also that the Upper Ultramafic and basalt are geologically and geochemically separate units. Therefore, it is interpreted that the Upper Ultramafic has thermally eroded the basalt and come to lie directly above the Windarra Ultramafic. Chert horizons logged in Cerberus at the top of the Windarra Ultramafic could therefore be a likely sulphide source for the nickel mineralisation located by PNRC0309.
Gold Mineralisation
An arsenic anomaly associated with hydrothermal veining within the basal chert and intruding felsics was also evident from the assays. A small group of selected samples were resubmitted for gold resulting in 1m
- 0.51 g/t Au in PNRC0264 from 30m (1m true width) and 2m @ 0.45 g/t Au in PNRC0278 from 33m (2m true width). Additional intersections >0.1 g/t Au also occur and are considered highly anomalous (refer to Table 6 in attachments).
Page 8
Poseidon acknowledges that Focus Minerals' exploration at the Beasley Creek Gold Mine (particularly along the Thompson Well Fault) runs in a northwest line some 1,900m to the northeast of the intersections at Crazy Diamond. Poseidon's recent mapping has noted a similar, parallel trend of shearing and quartz veining occurring through the prospect, particularly at the contacts between the basal chert and the Corridor Ultramafic, and then again between the Upper Ultramafic and the overlying Basalts. This compares favourably with the Beasley Creek geology and structural setting (see Figure 6).
Additional assaying of the RC samples will be undertaken based upon a detailed structural interpretation with more of a focus on potential gold mineralisation. This will then be augmented with Poseidon's existing gold geochemical dataset to assist further exploration.

SECTION 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
JORC Code explanation | Commentary |
Sampling techniques
Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling.
Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
Aspects of the determination of mineralisation that are Material to the Public Report.
In cases where 'industry standard' work has been done this would be relatively simple (e.g. 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information.
Reverse circulation drilling was used to obtain samples. The drill rig was an Atlas-Copco H8, specifically built to collect grade-control samples in an open pit environment and utilises the latest technology to ensure sample integrity and quality. Samples were collected every metre by a cyclone and splitter with reject material and samples being placed separately on the ground. 98% of the samples were dry.
All samples and sample numbers were checked for integrity prior to shipping for assay.
Drilling techniques
Drill type (e.g. core, reverse circulation, open-hole hammer, rotary | Reverse Circulation, see item above. |
air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, | |
triple or standard tube, depth of diamond tails, face-sampling bit or | |
other type, whether core is oriented and if so, by what method, | |
etc.). | |
Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed.
Measures taken to maximise sample recovery and ensure representative nature of the samples.
Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.
Recoveries were good with the exception of the first metre due to the loose, sandy cover.
Logging
Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.
Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography.
The total length and percentage of the relevant intersections logged.
All RC samples are geologically logged prior to shipment to the lab.
Sub-sampling techniques and sample preparation
If core, whether cut or sawn and whether quarter, half or all core taken.
If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry.
For all sample types, the nature, quality and appropriateness of the sample preparation technique.
Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.
Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling.
Whether sample sizes are appropriate to the grain size of the material being sampled.
RC samples were collected by use of a cone splitter.
No field sample duplicates or standards were used as the drilling was intended for geological purposes. Duplicate samples were performed by the laboratory along with internal standards and blanks. All QAQC samples exceeded industry standards.
Quality of assay data and laboratory tests
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.
For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors
Pulps were prepared by acid digest and analysed for the nickel suite of elements by ICP-OES using standard laboratory practices. Gold assays were prepared from the same pulps where a 50g charge was digested for fire assay. The laboratory's internal QAQC was used. No external lab checks were necessary at this stage.

applied and their derivation, etc.
Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.
Verification of sampling and assaying
The verification of significant intersections by either independent or alternative company personnel.
The use of twinned holes.
Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.
Discuss any adjustment to assay data.
Logging and assay data is electronically captured and up loaded into excel for processing as per industry standards and best practise.
Location of data points
Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.
Specification of the grid system used. Quality and adequacy of topographic control.
All collar surveys were completed to an accuracy of 3-5m using a handheld Garmin GPS. Holes were gyro surveyed upon completion and no significant deviation was reported over the short hole lengths drilled.
Data spacing and distribution
Data spacing for reporting of Exploration Results.
Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.
Whether sample compositing has been applied.
Samples were collected every meter. Hole spacing was determined by geology and holes were located where deemed necessary, maintaining a maximum 20m hole spacing.
Orientation of data in relation to geological structure
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.
If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.
Drill hole orientation was perpendicular to known and mapped geological continuity.
Sample security
The measures taken to ensure sample security.
Samples were collected by Poseidon personnel and loaded onto a truck for direct shipment to the lab.
Audits or reviews
The results of any audits or reviews of sampling techniques and data.
Internal sample audits revealed no issues with sample numbering or collection.
Section 2 Reporting of Exploration Results
Section 2: Reporting of Exploration Results
Mineral Tenement and Land Tenure Status
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.
The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.
The Crazy Diamond Prospect and Cerberus Deposit along with the Mt Windarra and South Windarra Mines are located on Special Act Lease MSA261, wholly owned by Poseidon Nickel Limited. The tenement is in good standing.
The Black Swan and Silver Swan deposits are situated on M27/200, wholly owned by Poseidon Nickel Limited. The tenement is in good standing.
Exploration Done by Other Parties
Acknowledgment and appraisal of exploration by other parties.
Newexco geological consultants continue to take an active part in Poseidon's exploration programs at Windarra, Lake Johnston and Black Swan, and their assistance and advice is appreciated. Newexco supply advice, geological and geophysical support and interpretation. Newexco has a long history of involvement in exploration at the Black Swan Project.
Geology
Deposit type, geological setting and style of mineralisation.
The exploration results relate to mineralisation encountered in a known Kambalda-style nickel environment dominated by high-MgO komatiite lava flows. Northwest orientated shears are thought to be the source of

If the exclusion of this information is justified on the basis that the | |
information is not Material and this exclusion does not detract from the | |
understanding of the report, the Competent Person should clearly | |
explain why this is the case. | |
Data Aggregation Methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated.
Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.
The assumptions used for any reporting of metal equivalent values should be clearly stated.
Grades have been aggregated using the length weighted average. SG information is not available due to the type of drilling and sampling employed.
See Table 2 and Table 3 for individual sample grades..
Relationship Between Mineralisation Widths and Intercept Lengths
These relationships are particularly important in the reporting of Exploration Results.
If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.
If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg 'down hole length, true width not known').
True widths are noted above where appropriate.

SILVER SWAN RESERVE ESTIMATE
Section 3 Estimation and Reporting of Ore Reserves
JORC Code explanation | Commentary | |
Mineral Resource estimate for conversion to Ore Reserves |
Description of the Mineral Resource estimate used as a basis for the conversion to an Ore Reserve.
Clear statement as to whether the Mineral Resources are reported additional to, or inclusive of, the Ore Reserves.
The Silver Swan Mineral Resource used as the basis of this Ore Reserve were estimated by Optiro Pty Ltd and was announced to market in August 2019.
Mineral Resources are reported inclusive of the Ore Reserves
Site visits
Comment on any site visits undertaken by the Competent Person and the outcome of those visits.
If no site visits have been undertaken indicate why this is the case.
The Competent Person (Mr Matthew Keenan) visited the site on 7th June 2016. The visit included inspection of the Silver Swan underground workings and surface infrastructure.
The site visits did not give the Competent Person any reason to believe that any portion of the Reserve Estimate will not be mineable.
Study status
The type and level of study undertaken to enable Mineral Resources to be converted to Ore Reserves.
The Code requires that a study to at least Pre-Feasibility Study level has been undertaken to convert Mineral Resources to Ore Reserves. Such studies will have been carried out and will have determined a mine plan that is technically achievable and economically viable, and that material Modifying Factors have been considered.
A Definitive Feasibility Study was completed in 2017 for the Silver Swan material being converted from Mineral Resource to Ore Reserve ("2017 FS").
Modifying factors accurate to the study level have been applied based on detailed stope design analysis. Modelling indicates that the resulting mine plan is technically achievable and economically viable.
Cut-off parameters
The basis of the cut-off grade(s) or quality parameters applied. | Cut-off grade parameters for the underground ore were determined based on |
the 2017 FS financial analysis and an underground contractor tender process | |
carried out in late 2018 for mining costs. The Silver Swan material was assumed | |
to be processed at the Black Swan Operations processing plant located at the | |
site. The fully costed stoping cut-off grade applied for the Silver Swan | |
underground was 2.9% Ni, and the incremental stoping cut-off grade was 2.5% | |
Ni. | |
A nickel price of $US7.00/lb and a USD:AUD exchange rate of 0.69 was used to | |
determine the cut-off grades.. | |
Mining factors or assumptions |
The method and assumptions used as reported in the Pre- Feasibility or Feasibility Study to convert the Mineral Resource to an Ore Reserve (i.e. either by application of appropriate factors by optimisation or by preliminary or detailed design).
The choice, nature and appropriateness of the selected mining method(s) and other mining parameters including associated design issues such as pre-strip, access, etc.
The assumptions made regarding geotechnical parameters (e.g. pit slopes, stope sizes, etc.), grade control and pre-production drilling.
The major assumptions made and Mineral Resource model used for pit and stope optimisation (if appropriate).
The mining dilution factors used.
The mining recovery factors used.
Any minimum mining widths used.
The manner in which Inferred Mineral Resources are utilised in mining studies and the sensitivity of the outcome to their inclusion.
The infrastructure requirements of the selected mining methods.
Detailed mine designs were carried out on the Silver Swan underground, and these were used as the basis of the Reserve estimate.
The Silver Swan Ore Reserve is planned to be mined using a bottom-up modified Avoca method with cemented rock backfill. This mining method has been selected based on detailed dynamic geotechnical modelling. Diesel powered trucks and loaders will be used for materials handling. Diesel-electric jumbo drill rigs will be used for development and ground support installation, and diesel- electric longhole rigs used for production drilling.
The mining methods chosen are well-known and widely used in the local mining industry and production rates and costing can be predicted with a suitable degree of accuracy. Suitable access is available through the existing workings, which have been kept pumped dry during care and maintenance.
Re-entry and refurbishment of capital development was costed in the Silver Swan mine plan based on detailed independent expert inspection.
Independent geotechnical consultants MineGeotech Pty Ltd and Beck Engineering Pty Ltd contributed appropriate geotechnical analyses to a suitable level of detail. These form the basis of mine design, ground support and mining method selection for the Reserve estimate.
Underground stopes were designed inclusive of minimum mining width of 2.5 m plus dilution volumes determined by independent geotechnical analysis and dynamic modelling. A global unplanned waste dilution of 7% was applied. An extra 2% of waste dilution at zero grade was applied to allow for overbog of fill. Non-fill dilution was assumed to carry a grade of 0.35% Ni, based on Mineral Resource information provided by Poseidon. Sub-level intervals are 25 m based on geotechnical advice. Maximum stope spans opened prior to filling are 5 m along strike. A mining recovery of 95% has been applied to all stopes. Ore development had an assumed 100% mining recovery, based on historical
Page 24
JORC Code explanation | Commentary |
experience and industry standards.
Only the Indicated portion of the Mineral Resource was used to estimate the Ore Reserve. All Inferred material has had grade set to waste for the purposes of evaluation. The Ore Reserve is technically and economically viable without the inclusion of Inferred Mineral Resource material. No Measured material was contained within the Mineral Resource
Most of the infrastructure required for the operations is already in place and has been under care and maintenance for approximately 11 years, including a processing plant and associated infrastructure, access roads, offices and ablutions, connections to the Western Power grid, power reticulation, and borefields. Allowance has been made for refurbishment of this infrastructure where required based on quotes provided by reputable independent vendors to an appropriate standard of detail.
Metallurgical factors or assumptions
The metallurgical process proposed and the appropriateness of that process to the style of mineralisation.
Whether the metallurgical process is well-tested technology or novel in nature.
The nature, amount and representativeness of metallurgical test work undertaken, the nature of the metallurgical domaining applied and the corresponding metallurgical recovery factors applied.
Any assumptions or allowances made for deleterious elements.
The existence of any bulk sample or pilot scale test work and the degree to which such samples are considered representative of the orebody as a whole.
For minerals that are defined by a specification, has the ore reserve estimation been based on the appropriate mineralogy to meet the specifications?
The Silver Swan Reserve estimate has been determined based on processing the material at the Black Swan Operations processing plant, in parallel with material from the Black Swan open pit and surface stockpiles. This processing plant is a conventional sulphide flotation concentrator consisting of a crushing circuit, grinding circuit, flotation circuit, thickening circuit and concentrate storage and handling facilities.
The Black Swan concentrator was successfully operated at throughput rates up to 2.2Mtpa during previous operations. All Reserve ore is expected to be processed through this concentrator at a nominal production rate of 1.1 Mtpa (inclusive of all ore sources). Suitable associated infrastructure is in place including power, water supply and storage, reagents storage, and tailings disposal and storage systems.
Extensive historical data exists on metallurgical characteristics of the Reserve orebodies.
Allowance has been made for the presence of deleterious elements (As and MgO) in the concentrate, based on historical realised penalties during sales from previous operations.
The metallurgical process is conventional, well understood and has many years of operational data to support the flotation responses of the Silver Swan ores. A metallurgical recovery of 92.5% has been applied to the Silver Swan ore material for economic analysis, based on this data.
The mineral value is not defined by a specification
Environmental
The status of studies of potential environmental impacts of the mining and processing operation. Details of waste rock characterisation and the consideration of potential sites, status of design options considered and, where applicable, the status of approvals for process residue storage and waste dumps should be reported.
Geochemical characterisation studies have been conducted that indicate that the rock mass is non-acid forming.
Poseidon has advised that most required approvals already issued under the Mining Act and Environmental Protection Act from previous operations remain current.
An additional geochemical study was conducted by MBS Environmental to assess the potential implications of storing tailings from the proposed ore blend on top of existing material in the tailings storage facility (TSF).
Works for the Stage 5 lift of the TSF commenced prior to the project being placed in care and maintenance. These works were incomplete and, as such, certification of the works by the Department of Environmental Regulation (DER) could not be obtained. The Works Approval authorising construction of the new embankment raise has since lapsed. A new Works Approval will be required prior to completing the lift. Under current approvals tailings cannot be deposited above RL11378.5 m.
Based on current approvals, it is estimated that there is currently 4 years of storage capacity in the TSF. This is sufficient to cover storage of tailings generated by processing the estimated Reserve ore.
At this point in time the Competent Person sees no reason permitting will not be granted within a reasonable time frame.
Infrastructure
The existence of appropriate infrastructure: availability of land for plant development, power, water, transportation (particularly for bulk commodities), labour, accommodation; or the ease with which the infrastructure can be provided, or
The project site is already developed and on care and maintenance. The underground workings are powered and kept dry through the installed pumping system.

JORC Code explanation | Commentary |
accessed. | All required surface infrastructure is already in place and requires only minor |
refurbishment. | |
Most required underground infrastructure is in place to commence mining | |
including primary ventilation fans, escapeways, high voltage power reticulation, | |
service water and compressed air. Allowance has been made for refurbishment | |
and recommissioning of this infrastructure based on inspections and detailed | |
quotes. Allowance has also been made for installation and hire of a refrigeration | |
plant for cooling of air flowing into the workings | |
As the site is 53 km from Kalgoorlie along well maintained gazetted roads, a | |
residential workforce will commute to site daily. | |
The mine is connected to the Western Power grid through two lines, one feeding | |
the concentrator and one feeding the other surface infrastructure and | |
underground workings. Allowance has been made for additional diesel | |
generated power to supplement this underground feed. | |
The existing water supplies from the Black Swan borefield, Silver Swan | |
underground dewatering system, Black Swan pit dewatering and the Federal pit | |
are sufficient to operate the plant at a throughput of 1.1Mtpa | |
Costs |
The derivation of, or assumptions made, regarding projected capital costs in the study.
The methodology used to estimate operating costs. Allowances made for the content of deleterious elements. The source of exchange rates used in the study. Derivation of transportation charges.
The basis for forecasting or source of treatment and refining charges, penalties for failure to meet specification, etc.
The allowances made for royalties payable, both Government and private.
The cost of plant refurbishment and site restart has been determined to an FS standard of accuracy. The Silver Swan ore will be processed in conjunction with the Black Swan open pit and therefore these costs were assumed to be shared between the ore sources.
The Silver Swan DFS capital and operating mining costs are based on detailed quotes from suppliers and mining contractors gathered as part of a contract tender process involving four reputable and experienced underground contractor firms carried out in May 2018. These were also benchmarked against similar operations in the WA Goldfields and historical data from previous operations at Silver Swan.
Operating costs for the processing plant were estimated from a combination of first principles, 2008/2009 historic operating costs and recent contractor quotations. They were also benchmarked against similar sized concentrators.
Allowance has been made for the presence of deleterious elements (As and MgO) in the concentrate, based on historical realised penalties during sales from previous operations.
The USD:AUD exchange rate assumed for the cost modelling was 0.69 based on recent market conditions.
Road and sea transport charges for concentrate are based on quotes from suppliers.
Treatment and refining charges are included in the payability factors determined from detailed discussions with potential offtake partners.
WA state royalties of 2.5 % and a third-party royalty of 1% have been applied to gross concentrate nickel revenues.
Revenue factors
The derivation of, or assumptions made regarding revenue factors including head grade, metal or commodity price(s) exchange rates, transportation and treatment charges, penalties, net smelter returns, etc.
The derivation of assumptions made of metal or commodity price(s), for the principal metals, minerals and co-products.
Forecasts for head grade delivered to the plant are based on detailed mine plans and mining factors.
A global payability has been applied to the Silver Swan Reserve Ore concentrate based on detailed discussions with potential offtake partners
A flat USD:AUD exchange rate of 0.69 was used in the financial model based on recent market conditions
A flat nickel price of US$7.00/lb has been assumed for the financial analysis, based on recent market pricing.
No value was assigned to any co-products as the forecast concentrate grades for these elements will not be sufficient to trigger payability.
Market assessment
The demand, supply and stock situation for the particular commodity, consumption trends and factors likely to affect supply and demand into the future.
A customer and competitor analysis along with the identification of likely market windows for the product. Price and volume forecasts and the basis for these forecasts.
Poseidon is currently reviewing offtake agreements with several potential offtake partners.
The volume of concentrate produced by processing the estimated Reserve will be too small to have an impact on the global market of nickel sulphide concentrate.

For industrial minerals the customer specification, testing and | The product is not an industrial mineral. |
acceptance requirements prior to a supply contract. | |
Economic |
The inputs to the economic analysis to produce the net present value (NPV) in the study, the source and confidence of these economic inputs including estimated inflation, discount rate, etc.
NPV ranges and sensitivity to variations in the significant assumptions and inputs.
The Silver Swan underground Ore Reserve has been assessed in a detailed financial model assuming cost and revenue factors described above.
The Reserve plan is economically viable and has a positive NPV at a 10% discount rate at the stated commodity price and exchange rate. Inflation has not been applied to the model.
Sensitivity analysis shows that the project is most sensitive to commodity price/exchange rate movements. The mine plan is still NPV positive at negative commodity price/exchange rate movements of 10%.
Social
The status of agreements with key stakeholders and matters leading to social licence to operate.
A compensation agreement exists between the Black Swan Nickel Operations and Mt Vetters Pastoral Station. This has been updated periodically as the operation has changed. Compensation previously paid under this agreement has been adequate to address all impacts of the project. No further compensation is required under the terms of this agreement. However, previous practice may have resulted in an expectation of additional compensation if significant additional land clearance is proposed. Significant land clearance is not required under the current Reserve estimate plan.
Poseidon will continue to communicate and negotiate in good faith with key stakeholders
Other
To the extent relevant, the impact of the following on the project and/or on the estimation and classification of the Ore Reserves:
Any identified material naturally occurring risks.
The status of material legal agreements and marketing arrangements.
The status of governmental agreements and approvals critical to the viability of the project, such as mineral tenement status, and government and statutory approvals. There must be reasonable grounds to expect that all necessary Government approvals will be received within the timeframes anticipated in the Pre-Feasibility or Feasibility study. Highlight and discuss the materiality of any unresolved matter that is dependent on a third party on which extraction of the reserve is contingent.
A formal process to assess and mitigate naturally occurring risks will be undertaken prior to execution. Currently, all naturally occurring risks are assumed to have adequate prospects for control and mitigation.
No marketing agreement has been signed but it is expected that such an agreement is highly likely to be arrived upon. Interest has been expressed by various potential offtake partners for the concentrate and it was successfully marketed during previous operations.
Based on the information provided, the Competent Person sees no reason all required approvals will not be successfully granted within the anticipated timeframe
Classification
The basis for the classification of the Ore Reserves into varying confidence categories.
Whether the result appropriately reflects the Competent Person's view of the deposit.
The proportion of Probable Ore Reserves that have been derived from Measured Mineral Resources (if any).
The Probable Ore Reserve is based on that portion of the Indicated Mineral Resource within the mine designs that may be economically extracted and includes an allowance for dilution and ore loss.
None of the Probable Ore Reserves have been derived from Measured Mineral Resources.
The result appropriately reflects the Competent Person's view of the deposit.
Audits or reviews
The results of any audits or reviews of Ore Reserve estimates.
The Ore Reserve estimate, along with the mine design and life of mine plan, has been peer-reviewed by Entech internally.
Discussion of relative accuracy/confidence
Where appropriate a statement of the relative accuracy and confidence level in the Ore Reserve estimate using an approach or procedure deemed appropriate by the Competent Person. For example, the application of statistical or geostatistical procedures to quantify the relative accuracy of the reserve within stated confidence limits, or, if such an approach is not deemed appropriate, a qualitative discussion of the factors which could affect the relative accuracy and confidence of the estimate.
The statement should specify whether it relates to global or local estimates, and, if local, state the relevant tonnages, which should be relevant to technical and economic evaluation. Documentation should include assumptions made and the procedures used.
Accuracy and confidence discussions should extend to specific
The Silver Swan design, schedule, and financial model on which the Ore Reserve is based has been completed to a Definitive Feasibility study standard, with a corresponding level of confidence.
Considerations in favour of a high confidence in the Ore Reserves include:
- The mine plan assumes a low complexity mechanised mining method that has been successfully implemented at various sites in the local area;
- The mine has been successfully operated previously and has been kept dry and accessible during the care and maintenance period, allowing detailed inspection of the workings and infrastructure;
- Material from the SS area has previously been successfully processed through the BSN plant and sufficient historical data exists to forecast metallurgical performance with a high degree of accuracy;
- Concentrate generated from SS ore has previously been successfully
