Zinc, Lead, Silver mine with trucks

Zinc, Lead and Silver

The Northern Territory is a major zinc producer, with the McArthur Basin forming part of the Carpentaria Zinc Belt, the world’s most productive zinc province that extends to Mount Isa in Queensland.

The one operating mine is McArthur River, the world’s fourth largest zinc mine, which is also a major producer of lead and silver. The McArthur Basin also contains the 2013 Teena zinc discovery, which is Australia’s largest zinc discovery this century.

The Pine Creek Orogen, Aileron Province and Bonaparte Basin also have known resources and high potential for polymetallic zinc, lead and silver deposits. The Lawn Hill Platform, which hosts the Century zinc mine in Queensland, also extends into the Northern Territory.

Remaining JORC Resources: 172 Mt at 9.8% Zn, 4.6% Pb and 47 g/t Ag

The McArthur River mine has been in operation since 1995, and has a remaining mine life of 30 years. The ‘Sedex’-style deposit occurs as fine-grained thinly bedded sulfide ore hosted in the 1640 million year old Barney Creek Formation of the McArthur Basin.

The open cut mining operation produces zinc and zinc-lead concentrate, which is exported from the Port of Bing Bong on the Gulf of Carpentaria.
