Name of the Project
Diamba Sud gold project.

Location
The 53.2 km² Diamba Sud exploration licence, in eastern Senegal.

Project Owner/s
Boya SAU, a wholly owned Senegalese subsidiary of Chesser Resources. The Senegalese government is entitled to a 10% free carried interest in the project upon granting the mining licence.

Project Description
Diamba Sud comprises the Area A, Area D and Area D South openpits.

The project mining inventory has increased by 17%, to 13.9-million tonnes at 1.7 g/t gold for 762 000 oz of contained gold.

The project is expected to produce 715 000 oz of gold over the 7.5-year mine life, averaging at about 100 000 oz/y at an all-in sustaining cost (AISC) of $849/oz.

During the first two years of production, Diamba Sud is expected to produce 223 000 oz of gold at an average AISC of $612/oz.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The March 2022 scoping study estimated a pretax net present value (NPV), at a 5% discount rate, of $402-million and an internal rate of return (IRR) of 69% at a $1 800/oz gold price, with a payback of 1.25 years from commercial production.

The project’s NPV, at a gold price of $1 800/oz, has now been estimated at $296-million while its IRR is estimated to be 55%, with the payback period now estimated at 17 months from commercial production.

Capital Expenditure
Capital cost estimates are estimated at $149-million.

Planned Start/End Date
Not stated.

Latest Developments
Chesser MD and CEO Andrew Grove has said the project’s economics continue to improve as the company refines the project, and discovers and then converts additional mineralisation into higher-confidence mineral resources.

Based on the drilling under way at Area D and other prospective targets, Chesser expects resource growth to continue at Diamba Sud and the adjacent Bondala tenement. Mineral resources have increased at Area D with the extension of mineralisation to the west, which remains open in that direction.
