Name of the Project
Sabodala-Massawa gold mine expansion.

Location
Senegal.

Project Owner/s
Endeavour Mining.

Project Description
The Sabodala-Massawa mine comprises two mining licences, the Sabodala and Massawa exploitation permits, and two other exploration permits.

The project has proven and probable reserves of 66.4-million tonnes grading 2.08 g/t gold for 4.44-million ounces of gold. Measured and indicated resources, including reserves, are estimated at 110.1-million tonnes grading 1.94 g/t gold for 6.88-million ounces of gold. Indicated resources are estimated at 24.3-million tonnes grading 2.16 g/t of gold and 1.68-million ounces of gold.

A definitive feasibility study (DFS) has recommended the expansion of the Sabodala-Massawa complex by supplementing the current 4.2-million-tonne-a-year carbon-in-leach plant with a 1.2-million-tonne-a-year BIOX plant to process the high-grade refractory ores from the Massawa Central Zone and Massawa North Zone deposits.

Total production over the project’s estimated 14-year mine life is estimated at 3.95-million ounces, with average production estimated at 282 000 oz/y.

The project presents significant upside potential, as the DFS does not include the conversion of the previously announced discovery of 709 000 oz of measured and indicated resources.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The project has a pretax net present value, at a 5% discount rate and $1 700/oz gold price, of $1.13-million and an internal rate of return of 83%, with a payback of 1.3 years.

Capital Expenditure
The project is estimated at $290-million.

Planned Start/End Date
First gold pour from the BIOX plant expected in early 2024.

Latest Developments
Endeavour has reported that its Sabodala-Massawa expansion project is progressing well, with the project being on time and within budget.
