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.

Key developments during FY2018

The major smelter maintenance upgrade in August 2017 was the largest planned shutdown ever undertaken at Olympic Dam and ran for more than 100 days. Other major upgrade work was carried out on the refinery, concentrator and site technology to ensure the ongoing reliability and safety of the Olympic Dam operation.

Guidance for Olympic Dam was reduced to approximately 135 kilotonnes (kt) following a slower than planned ramp-up after completion of the major smelter maintenance campaign.

However, Olympic Dam slightly exceeded the revised guidance for the full FY2018 at 137 kt.

First ore from the higher-grade Southern Mine Area was extracted in early FY2018 with development continuing.

Looking ahead

Following the key infrastructure upgrade in FY2018, Olympic Dam will see a gradual increase in copper production with continued development into the Southern Mine Area.

There are other expansion plans for Olympic Dam, such as the Brownfield Expansion Project, which is expected to be considered by the Board in CY2020, and could see production grow to approximately 330 kilotonnes per annum (ktpa).
