Gold mine

McArthur River Mine

Northern Territory, Australia

53 MW

The McArthur River Mine in the Gulf of Carpentaria, Northern Territory of Australia, is one of the world’s largest providers of zinc in bulk concentrate form. Operated by McArthur River Mining Pty Ltd (MRM), a wholly-owned subsidiary of the international Glencore group, the mine produces approximately 3 percent of the world’s total zinc resources each year. The mine’s processing plant was doubled in size in 2014, which created the need for a new power source.

Wärtsilä has an established track record of delivering high quality. We were impressed by Wärtsilä’s proposal to supply an efficient power plant solution on a fast-track basis. This was an important consideration in choosing Wärtsilä as our engine supplier for this project.
