CSA Mine is located near Cobar, Central Western NSW. It is operated by Cobar Management Pty Ltd (CMPL) – owned by Glencore Xstrata.
The mine initially started in 1871 with an erratic production history until 1964, when Broken Hill South Ltd began large scale production. The mine passed to CRA in 1980 and then to Golden Shamrock Mines in 1992. The mine was closed in 1997/8 following its acquisition by Ashanti Goldfields and was reopened in 1999 by Glencore.
Since 1965 the mine has extracted substantial quantities of zinc, lead, silver and copper, but today, CSA Mine focuses on mining copper, with a silver co-product.
The underground mine produces over 1.1 million tonnes of copper ore and in excess of 185,000 tonnes of copper concentrate per annum.
