This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. The total resource to be mined is 18,715,000 tonnes. Ore is hauled 1,068 meters to an ore stockpile. Waste is hauled 535 meters to a waste rock dump. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material.
