Yaramoko Gold Heading for June Production Start

The Yaramoko project is designed to produce an average of 99,500 oz/y of gold over a mine life of 7.4
years. The plant, shown here during construction, has a nominal throughput capacity of 270,000 mt/y.

Roxgold Inc. reported in early April that construction was 84% complete at its high-grade Yaramoko gold project in western Burkina Faso and that the fi rst gold pour was scheduled for June. Plant commissioning was under way, and ore development in the underground mine was progressing well on four levels. More than 23,000 metric tons (mt) of ore had been placed on the run-of-mine pad.

Yaramoko is designed to produce an average of 99,500 ounces per year (oz/y) of gold over a mine life of 7.4 years based on probable reserves of 2 million mt grading 11.83 g/mt gold and containing 759,000 oz of gold. As of the end of March, Roxgold had spent approximately $78 million on Yaramoko project development and expected to complete the project within its budget of $110.8 million.

The Yaramoko process plant has designed throughput capacity of 270,000 mt/y. The fl owsheet includes primary crushing, grinding through a singlestage SAG mill, gravity concentration, classifi cation, leaching and adsorption, tailings thickening, electro-winning, and smelting.

The company said underground development is advancing well, with contractor African Underground Mining Services delivering better than expected development rates in ore and waste. As of early April, the access ramp had advanced to 610 m from the portal and opened up four levels for development of ore.

Endeavour said it is encouraged by what it has observed in the ore drives, with the orebody profi le and thickness consistent with the block model. Initial face sampling of crosscuts indicates that ore grades are consistent with expectations. Stoping activities are scheduled to begin in the third quarter.

Roxgold has initiated an 11,000-m diamond drilling program, including resource defi nition and expansion drilling, with expectation that the results will be incorporated into an updated life-of-mine plan in late 2016.
