In 2006, concentrator throughput was 18.5t and 21.9t of waste rock was removed. At feed grades of 0.4% for copper, 0.25g per tonne for gold and 2.72g per tonne of silver in 2006, the mine produced 240,000t of copper concentrate. This concentrate contains 66,100t of copper, 35,700kg of silver and 2,340kg of gold. Aitik contractors
