Olympic Dam

Olympic Dam

Underground copper mine, also producing uranium, gold and silver

Explore our global locations

Located 560 kilometres north of Adelaide, Olympic Dam is one of the world’s most significant deposits of copper, gold, silver and uranium.

Olympic Dam is made up of underground and surface operations and operates a fully integrated processing facility from ore to metal.

The underground mine is made up of more than 450 kilometres of underground roads and tunnels. Ore mined underground is hauled by an automated train system to crushing, storage and ore hoisting facilities.

The processing plant consists of two grinding circuits in which high-quality copper concentrate is extracted from sulphide ore through a flotation extraction process. Olympic Dam has a fully integrated metallurgical complex with a grinding and concentrating circuit, a hydrometallurgical plant incorporating solvent extraction circuits for copper and uranium, a copper smelter, a copper refinery and a recovery circuit for precious metals.

It’s an exciting time to be part of the #OlympicDamSquad – hear from our team about why they love it!

Key developments during FY2020

Olympic Dam achieved solid underground mine performance in FY2020 with strong development metres, as well as record annual gold production. Underground development into the Southern Mine Area progressed to plan over the year, and provided access to higher copper grade ore. Preparatory work was undertaken in the September 2019 quarter related to the replacement of the refinery crane with the physical replacement and commissioning expected to be completed in the March 2021 quarter.

Looking ahead

Preparations are well advanced for the next Smelter Campaign Maintenance to be executed early in FY2022. Olympic Dam has a range of future growth options under consideration as part of its sustained, long-term growth strategy, from incremental debottlenecking through to large scale investments. A third phase of exploration drilling on the Oak Dam project has been completed with additional geotechnical and geo-metallurgical data collected to assist in the understanding of the deposit. Further drilling will be conducted in FY2021, which will inform our next steps with the project.
