Name of the Project 
Kiniero gold project.

Location
Conakry, Guinea.

Project Owner/s
Canadian mining company Robex Resources Inc. 

Project Description
An updated feasibility study completed in 2024, using a base case gold price of $1 800/oz, demonstrated the project’s ability to produce an average of 139 000 oz/y of gold over a nine-year life-of-mine, compared with 90 000 oz in the 2023 feasibility study. Average gold production is estimated at 154 000 oz/y in the first six years. 

The feasibility study notes that the mine plan optimisation efforts prioritise a stable, long mine life, rather than peak upfront production.

Mining is expected to be undertaken by conventional owner-operated truck-and-excavator openpit mining in the SGA, Jean, SGD, Sabali South, Mansounia, Sabali North and Central pits.

Mining in upper oxide layers will be free-dig, with drill-and-blast required in areas that mine through the transitional material into fresh rock. 

Ore will be processed on site, at a centrally located six-million-tonne-a-year processing facility near the mining areas. The gold will be recovered in a beneficiation plant designed to process a blend of oxide, laterite, transition and fresh ores from various ore deposits.

The flowsheet includes two crushing circuits, semiautogenous (SAG)/ball grinding, and pebble crushing milling, dual carbon-in-leach circuits, split Anglo-American Research Laboratories elution and gold electrowinning, as well as carbon regeneration, which are well proven in the industry.

Existing mining infrastructure will be refurbished, with minimal additional infrastructure required.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
Using a base case gold price of $1 800/oz, the project has a pretax net present value, at a 5% discount rate, of $480-million and an internal rate of return of 47%, with a payback of 2.1 years.

Capital Expenditure
Preproduction capital is estimated at $243-million (2023: $160-million).

Planned Start/End Date
First gold pour is on track for the fourth quarter of 2025.

Latest Developments
Robex reported in January 2025 that the updated feasibility study was on track for the first quarter of 2025.
