The area was mined by Homestake Mining and then Barrick Gold Corporation. The geology is considered by most workers to be a volcanogenic massive sulfide ore deposit containing gold, silver, copper, zinc, arsenic, antimony and mercury.[1] The mine produced 3.3 million ounces of gold and 160 million ounces of silver at average grades of 45 g/t gold and 2,224 g/t silver from 1994 -2008.[2]
