HIGHLIGHTS
SCOPING STUDY CONFIRMS ROBUST LOW-COST GOLD PROJECT AT DIAMBA SUD
STUDY HIGHLIGHTS1
• Post-tax NPV5 A$419M (US$301M) and IRR 59% at a US$1,800/oz gold price
• Payback 1.25 years from commercial production
• 7.5-year Project life producing 704koz gold at an average AISC of US$820/oz
• First two years of gold production totals 244koz at an average AISC of US$545/oz
• Total Project mining inventory of 14.7Mt at an average grade of 1.6g/t gold (70% from Indicated Resources) containing 750koz of gold at a strip ratio of 2.8
• Ore mined and processed in first two years of operations @ an average grade of 2.0g/t gold (83% from Indicated Resources) containing 257koz of gold at a strip ratio of 1.9
• Pre-production capital cost of US$159M including US$23M contingency
• Industry standard 2Mtpa CIL processing circuit with average gold recoveries of 94%
• Significant Resource upside - Areas A and D remain open and new discovery at Karakara with drilling underway
• ESIA baseline activities have commenced
• Board approval to commence a Definitive Feasibility Study
• Diamba Sud represents a potential long life, technically simple, low risk and highly profitable mining operation that will generate significant benefits to all stakeholders
The Scoping Study results clearly demonstrate the very significant potential value from a future mine development at Diamba Sud. Importantly the study does not include any potential Mineral Resources from the new discovery at Karakara or any further resource additions that might result from the current 15,000m to 20,000m drilling program all of which would further enhance the value of the Diamba Sud Project.
BONDALA AND MOURICHOU EXPLORATION LICENSES GRANTED
The grant of the new tenements significantly adds to the Company's land position in Senegal and covers some highly prospective geological terrains especially the Bondala license which contiguous to the north of the Diamba Sud tenement.

The Company is not aware of any new information or data that materially affects the production targets and financial forecasts derived from the production targets in the referenced ASX announcement and confirms that all material assumptions and technical parameters underpinning those production targets and financial forecasts continue to apply and have no materially changed. All Scoping Study results are approximate. Cost estimates are subject to Scoping Study level of accuracy of +/- 35%.
STRONGLY SUPPORTED $12M PLACEMENT
On the 31 March 2022 the Company received firm commitments for a $12.1 million private placement (115,238,096 shares at an issue price of $0.105 per share) which was subsequently completed on the 8 April 2022.
The placement received very strong support from existing shareholders and a number of new domestic and offshore institutional and sophisticated investors. Directors subscribed for 3 million shares which are subject to shareholder approval at a future General Meeting of shareholders.
CORPORATE
• Cash at the end of the quarter totalled A$3.9 million.
• Subsequent to the end of the quarter approximately $11.5 million was received from the placement net of fees.
UPCOMING ACTIVITIES
• An extensive 15,000 to 20,000m drill program is well underway with a total of 5,464m of drilling completed during the quarter (31 RC holes for 3,651m and 8 Diamond holes for 1,813m) mainly from the Karakara discovery area and Area A NE. No assays results were returned during the period
• The drill program is aimed at adding Karakara to the Resource inventory, extending Resources at Areas A and D and to systematically explore other prospective targets on the Diamba Sud exploration tenement
• The first assay results will be from the new discovery area at Karakara and are expected to be received in April and to continue throughout the June quarter
• Baseline environmental and ESIA work has commenced over the Project area
• Definitive Feasibility Studies to commence
• Initial reconnaissance exploration of the newly granted tenements, Bondala and Morichou

Chesser Resources Limited ("Chesser" or the "Company", ASX:CHZ) is pleased to present its Quarterly Activities Report for the three months ended 31 March 2022. The Company's primary focus during the reporting period continued to be the advancement of its Diamba Sud gold Project in Senegal.
SCOPING STUDY CONFIRMS ROBUST LOW-COST GOLD PROJECT AT DIAMBA SUD
The Scoping Study details the potential for an open pit mining operation and gold processing plant at Chesser's Diamba Sud Gold Project in Eastern Senegal.
The Scoping Study is based on the 781koz gold maiden Mineral Resource inventory covering Area A and Area D, released to the market on the 16 November 2021, summarised in Table 1. Resources do not include mineralisation from the new discovery at Karakara, located 1.2km from the Area D pit, Figure 1.

A standard 2Mtpa CIL SAG/Ball circuit gold processing plant was considered to be appropriate for the Scoping Study. Tailings from the CIL will undergo cyanide detox and report to a tailings storage facility. Raw water for processing will be sourced by seasonal pumping from the Falémé River, approximately 7km to the east, to a water storage dam.
Mining from three open pits (Area D, Area A and Area D South) is assumed to be undertaken by a mining contractor utilising standard truck and shovel open pit mining methods.
The project will include an on-site accommodation village housing part of the workforce, with the balance residing in adjacent communities. Power will be generated on site.
The cash flow and economic analysis has been prepared on a 100% of project, constant first quarter calendar 2022 US dollar basis. Cost estimations are considered to be at a scoping study level of accuracy of +/-35%.
The Scoping Study demonstrated the technically simple and low risk nature of the Project and the very significant potential economic value that would result from a future development at Diamba Sud. There remains significant upside both in exploration to add to the Mineral Resource inventory and from future Project optimisation studies. A summary of the initial physical and financial evaluation of the Project is shown in Table 2.

PRODUCTION PROJECTIONS
The production profile of the Diamba Sud Gold Project demonstrates annual production of up to 136koz in year two, with an average production of 94koz per year over the current 7.5 year Project life. 70% of the gold production is sourced from Indicated Resources and the remainder from Inferred Resources. During the first two years of production which includes the payback period, gold production is sourced 83% from Indicated Resources, mainly from the Area D pit.

SENSITIVITY ANALYSIS
Sensitivity analysis shows the Project to be resilient to changes in both capital and operating costs. Like most mining projects the economics are most sensitive to changes in revenue parameters such as the commodity price.
