In Australia, the McArthur River Mine is a sizable zinc, lead, and silver mine situated in the Northern Territory, close to the Gulf of Carpentaria, approximately 970 kilometres southeast of Darwin. McArthur River Mining (MRM), a division of the Swiss mining corporation Glencore, is in charge of running it. In order to take advantage of one of the biggest and richest sedimentary stratiform ore bodies in the world, the mine was converted from an underground operation in 1995 to an open-pit mine in 2009.
Known as “HYC” (Here’s Your Chance), the deposit was found in the 1950s, but transportation expenses and practicality concerns caused the initial development to be postponed. Plans for mine expansion called for rerouting roughly 5.5 km of the McArthur River to access the ore body, which is partially beneath the river itself. Environmental organisations and traditional owners filed legal challenges against this contentious diversion.
With recent expansions aiming to increase throughput to 5.5 million tonnes per year, the mine currently produces about 2.5 million tonnes of ore annually, with notable amounts of zinc, lead, and silver. The Bing Bong loading facility on the Gulf of Carpentaria ships the processed concentrates to international markets, primarily in China, Japan, and Europe.
About 259,700 tonnes of zinc, 51,800 tonnes of lead, and more than 1.7 million ounces of silver were produced at the McArthur River Mine in 2024. With roughly 1,320 workers and contractors, as well as large purchases of goods and services, it makes a substantial economic contribution to the Northern Territory.
The mine is regarded as one of Glencore’s most isolated operations in Australia.
The Gudanji people’s traditional lands are where the site is situated, and the environmental impact and river diversion have caused controversy among Indigenous groups and environmental advocates.
Overall, McArthur River Mine is a world-class zinc and lead operation with a complex history of development, environmental considerations, and significant economic impact in northern Australia.
