The Plutonic Gold Mine is a gold mine located 82 km east-northeast of Peak Hill, Western Australia.

It is owned and operated by Canadian miner Superior Gold Inc. and located in the Plutonic Well Greenstone Belt. 5.5 million ounces of gold have been produced from both open pit and underground operations at Plutonic, since it opened in 1990.[2]

History

Gold mines in the Mid West region

In 1988, Great Central Mines discovered the deposit which was to become Plutonic, which it sold for A$50 million in 1989,[3] to Plutonic Resources, then a major Australian gold mining and exploration company, who commenced production in 1990.[4][5] Homestake Mining Company purchased Plutonic in April 1998 for more than $1.0 billion,[6] and, in turn, Homestake was acquired by Barrick Gold at the end of 2001.[7]

The mine was acquired by Superior Gold from Northern Star Resources in September 2016 who acquired it from Barrick Gold in February 2014.[8][9][10]
