Name and Location
Yaramoko – 55 Zone gold project, Burkina Faso.

Client
Roxgold.

Project Description
Yaramoko is an underground mine that benefits from a small surface footprint, as well as existing infrastructure on the permit. It is one of the highest-grade gold mines in the world.

The mine plan is based on a 4.9 g/t cutoff at a minimum width of 1.6 m. A 750 t/d extraction rate is forecast from the underground mine, with a life-of-mine of 7.4 years at 99 500 oz/y of gold for a total of 735 430 oz of gold contained within an estimated two-million tonnes of ore at a grade of 11.8 g/t. The typical planned stope has a 25 m strike length, a vertical height of 34 m and the full vein width.

The processing facility is sized for a throughput of 750 t/d and will include single-stage jaw crushing, semiautogenous milling, gravity recovery, leaching and adsorption circuits, gold recovery and thickening.

The design philosophy incorporates a requirement that the processing facility be amenable to expansion with minimum capital requirements. The facility will be able to readily increase throughput in the event that the extraction rate at the 55 Zone is higher than forecast or addi-tional sources of ore feed are developed.

Net Present Value/Internal Rate of Return
The project has a pretax net present value, at a 5% discount rate, of $300-million and an internal rate of return of 53.7%, with a 1.5-year payback on initial capital.

Value
$106.5-million.

Duration
The company expects to ramp up to commercial production in the third quarter of 2016.

Latest Developments
Roxgold poured its first gold at the Yaramoko gold project in May. The initial gold pour totalled 1 020 oz.

Plant practical completion and processing performance tests confirming nameplate throughput and recovery assumptions were completed over a month ahead of schedule and mine development remains ahead of plan in the year to date.

In the underground operation, four sublevels are fully developed to the eastern end of the resource and ore development is continuing to the western end of the first mining block on three levels.

Ore development is expected to increase further when development starts in Block 2 on the western side of the deposit. Stoping operations in Block 1 are expected to start this month, further increasing the mine’s productivity.

Currently, there are about 30 000 t of mill feed grade ore on the run-of-mine pad. Key Contracts and Suppliers
None stated.

On Budget and on Time?
The Yaramoko mine was built on budget, ahead of schedule.
