About Us

CSA Mine is one of Australia’s longest operating copper mines with a history stretching back almost 150 years. At 1.9 kilometers deep, CSA is the second deepest copper mine in Australia and the third highest copper grade in the world. Located near the NSW town of Cobar, CSA Mine employs around 550 people and produces approximately 40,000 tonnes of copper concentrate per year. The ore is mined and processed on site and then transported by rail 700km to the Port of Newcastle for export. CSA Mine was acquired by Metals Acquisition Limited in June 2023.
