McArthur River zinc mine
The McArthur River mine is one of the world's largest zinc, lead and silver mines, situated about 70 kilometres southwest of Borroloola, near the Gulf of Carpentaria in the northeastern Northern Territory, Australia. It is operated by McArthur River Mining (MRM), a subsidiary of the Swiss mining company Xstrata. Although discovered in the 1950s, when it was originally called the HYC ("Here's Your Chance") deposit, it only opened as a mine in 1995. Initially an underground mining operation, the mine has been converted to open-cut.
==Economic benefits==
2.5 million tonnes of ore containing 383kt of zinc, 93kt of lead and 110t of silver are currently mined per year〔
〕
. Following a comprehensive 16-month study of the environmental impact, a new development project will increase production to 5.5 million tonnes per year. The workforce will increase to 735 by 2020 with a high level of Indigenous participation. The mine will operate until 2038 and will contribute $8.4 billion to the Northern Territory economy and $9.3 billion nationally.
