LONDON, Oct 31 (Reuters) - Glencore's Black Star Open Cut mine in Queensland, part of the Mount Isa Mines complex, has been put on care and maintenance after mining out its existing reserve, the company said in a statement on Monday.
The mine had produced around 40 million tonnes of ore and 1.75 million tonnes of contained zinc since opening in 2004, Glencore GLEN.L said.
Zinc CMZN3 , already one of this year's strongest performing commodities, rallied to a five-year high after the announcement on Monday.
