Open-pit mining progressed from the 1042 bench to the 1012 bench during the year with mine production averaging 1,250 tonnes per day (ore and waste). In addition to the ore shipped to the mill, a lower grade stockpile was established on-site, containing approximately 150,000 tonnes of material at an estimated gold grade of 0.75 gpt Au.
Waste rock is hauled to waste rock dumps. Rock that contains oxidized copper mineral ore is hauled out of the pit to a stockpile. Processing: Crushed ore is conveyed into the mill at a rate of ~85,000 tonnes per day. The ore first enters the ball mill circuits which pulverize the ore to sand.
