Murrin Murrin Mine


The Murrin Murrin Mine 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 initiated as a 60/40 joint venture between Murrin Murrin Holdings, a subsidiary of Anaconda Nickel and Glenmurrin, a subsidiary of Glencore. In 2003 Anaconda changed its name to Minara Resources. In November 2011, Minara Resources was acquired by Glencore. The mine opened in 1999.

Geology

Murrin Murrin mines a laterite nickel ore formed by deep weathering of a peridotite ultramafic rock.

Problems with the process plant

Significant problems and delays were encountered in the design, construction and commissioning of the ore process plant at Murrin Murrin.
The designers, Fluor Daniel eventually had to pay the joint venture partners $155 million in an out-of-court settlement. It was the second successful claim against Fluor, Murrin Murrin owners having been awarded $147 million from the first phase of their claim against Fluor, a sum which ultimately was reduced to $39.8 million. The Murrin Murrin project's original cost estimate of $1 billion had $1.6 billion. In December 1998, Anaconda Nickel terminated Henry Walker as mining contractor.
