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 flowsheet includes primary crushing, grinding through a single-
stage SAG mill, gravity concentration, classification, 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 profile 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 definition and expansion drilling, with expectation that the results will be incorporated into an updated life-of-mine plan in late 2016.
