OZ Minerals is an Australian mining company engaged in copper and gold production, operating primarily in South Australia and international regions. The company develops underground and open-pit mining projects supported by concentrator facilities. OZ Minerals contributes to base metal supply chains serving industrial and infrastructure markets.

OZ Minerals was formed in 2008 through the merger of Oxiana and Zinifex.

The company developed the Prominent Hill copper-gold mine in South Australia, expanding operations during the 2010s.

In 2023, OZ Minerals was acquired by BHP, integrating assets into a larger global mining group.

Primary Mining Regions
OZ Minerals operated primarily in South Australia, with major assets including the Prominent Hill and Carrapateena copper gold mines. These projects are located within the Gawler Craton, a well known mineral province with significant copper resources. The region benefits from stable regulatory frameworks and established mining development infrastructure.

Infrastructure and Processing Facilities
Operations included underground mining systems supported by on site concentrator plants that processed ore into copper concentrate. Road transport linked mine sites to rail networks and onward to export terminals in South Australia. Integrated processing and logistics systems ensured steady concentrate shipment to international smelters.

Strategic Geographic Advantage
South Australia provides strong infrastructure reliability and direct access to export corridors. Proximity to established ports strengthens integration into global copper supply chains serving industrial and renewable energy markets.

In 2024, OZ Minerals assets operated under integrated management structures, maintaining steady copper and gold output in South Australia. Operational programs focused on underground efficiency and concentrator optimization.

Infrastructure reliability initiatives and digital monitoring systems supported production consistency and logistics coordination to export terminals.

In 2025, emphasis remains on disciplined production planning and continued integration within broader global copper supply operations.
