Name of the Project
Bankan gold project.

Location
Siguiri basin, in the north-east of Guinea.

Project Owner/s
Explorer and developer of gold reserves in West Africa Predictive Discovery.

Project Description
A definitive feasibility study (DFS), completed in June 2025, has provided greater confidence in development and operating plans, reaffirming the project’s large scale, long mine life and compelling financials.

The DFS proposes openpit mines at NEB, Gbengbeden (GBE) and BC, with associated waste-rock dumps at NEB and BC, and an underground mine beneath the NEB pit, with access from the GBE pit and the associated ventilation, cooling and paste plant infrastructure.

Average production over the 12.2-year life-of-mine (LoM) is about 250 000 oz/y from mill feed of 54.5-million tonnes at 1.86 g/t containing 3.26-million ounces of gold. Openpit mining will be used as a conventional drill, blast, truck and shovel operation, which is considered appropriate for the style of the deposits. The mining method is based on three pit stages in NEB and a single pit stage each in GBE and BC.

The NEB openpit will be mined in three stages to prioritise access to higher-grade ore and allow for material movements to be balanced over the LoM. Prestripping at NEB will be initiated three months prior to the start of production and mining will continue throughout the LoM.

The GBE pit will be mined and stockpiled over the first nine months of the construction period to allow for a portal to establish underground access to fresh rock at the base of the pit. Underground development will take about 15 months to access the first stope ore, with development ore stockpiled during this period.

The BC openpit will be mined in years 9 to 11, deferring the additional capital cost required to establish mining operations at the deposit.

The underground mining method is a combination of transverse and longitudinal longhole stoping with engineered paste fill.

The process plant design has been based on a throughput of 4.5-million tonnes a year and will use conventional carbon-in-leach technology with upfront gravity recovery.

The project has shown excellent potential for the mine life to be extended through additional drilling and exploration. The NEB deposit is open at depth beneath the existing underground mineral resources, while the BC and GBE deposits have the potential to be expanded through additional targeted drilling. There is also significant exploration potential at near-resource and regional exploration targets.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The DFS notes that, at a consensus gold price assumption of $2 400/oz, the project delivers an after-tax net present value, at a 5% discount rate, of $1.64-billion and an internal rate of return of 46%, achieving payback in 1.9 years.

Capital Expenditure
Total preproduction costs are estimated at $463-million.

Planned Start/End Date
Construction is scheduled over a two-year period, which is expected to start in the second quarter of 2026, following execution readiness activities and selected early works, consequently allowing for the start of commercial production in the second quarter of 2028.
