CSA Mine is an underground copper mine located in Cobar, Central Western NSW.

Employing over 350 people, CSA Mine is operated by Cobar Management Pty Ltd (CMPL) - a wholly owned Australian subsidiary of Glencore International AG (Switzerland).

CSA Mine extracts over 870,000. tonnes of copper ore and produces in excess of 150,000 tonnes of copper concentrate per annum. This concentrate is exported to smelters around the world.  

Copper is used in mobile phones, computers, cars, electronic goods such as radios and televisions as well as air conditioners, electrical generators and wiring.

Copper ore is extracted by underground mining methods using open stopes with backfill. Ore is hoisted to the surface treatment plant where it is processed using semi-autogenous grinding and froth flotation to produce a high quality concentrate. The operation is highly mechanised and uses the latest technology to mine and process ore in the most productive and cost effective manner.
