The Murrin Murrin Joint Venture is a major nickel-cobalt mining operation being conducted in the North Eastern Goldfields, approximately 45 km east of Leonora, Western Australia. The Project was a joint venture between Murrin Murrin Holdings Pty Ltd, a wholly owned subsidiary of Minara Resources Ltd (whose share is 60%) and Glenmurrin Pty Ltd, a wholly owned subsidiary of Glencore International AG, which had a 40% share but also owned 70% of Minara. As of November 2011, Minara Resources was fully acquired and is now wholly owned by Glencore International. The mine opened in 1999.
