BHP Awards $40 Million Design and Supply Contract for Olympic Dam Expansion, another Step in South Australia's Copper Growth

BHP has awarded a $40 million engineering, procurement and construction management contract to a Fluor-Hatch joint venture for the proposed expansion of its copper smelter and refinery at Olympic Dam, progressing the company's vision to increase South Australian copper production to more than 500,000 tonnes a year by the early 2030s.

BHP is moving forward with its South Australian growth plans. The mining giant has awarded a contract worth more than $40 million to a joint venture between Fluor Australia and Hatch for engineering, procurement and construction management services for the proposed expansion of its copper smelter and refinery facilities at Olympic Dam.

The contract will be executed in stages as BHP progresses towards a final investment decision, currently expected in the first half of financial year 2027. The first stage will focus on overall strategy and planning through the project's study phases.

The expansion is part of BHP's broader strategy to lift copper production in South Australia to more than 500,000 tonnes of refined copper cathode a year by the early 2030s, and up to 650,000 tonnes from the mid-2030s. The company produced approximately 322,000 tonnes last financial year.

The project involves upgrading the existing smelter and refinery at Olympic Dam to a two-stage smelter with extended refinery capacity. BHP Copper SA Asset President Anna Wiley described the contract award as "another step forward in our strategy to increase the production of SA's high-quality copper resources."

"BHP has established a world-scale copper province in South Australia and we are working at pace to progress our plans to lift production further over the coming decade," Wiley said.

The expansion is underpinned by strong demand forecasts. Global copper demand is projected to increase by around 70 per cent by 2050, driven by the global transition to electric vehicles, renewable energy, data centre growth, and traditional uses like housing construction .

South Australia is home to approximately 70 per cent of Australia's economic copper reserves and copper exports reached $3.1 billion in 2025, up 16 per cent from the previous year. The state recently received a record $25.6 million royalty payment from BHP's Olympic Dam operation for the month of April.

Here is the question this contract award raises. BHP is investing more than $40 million just to plan the expansion, with a final investment decision still more than a year away. South Australia is pushing to modernise its regulatory framework and secure billions in future investment. When the state is betting its economic future on a 70 per cent demand surge and the miner is spending millions to design an expansion it hasn't yet approved, who is taking the bigger risk?

As BHP awards the design and supply contract for its Olympic Dam expansion and moves closer to unlocking South Australia's copper potential, The Silicon Review asks a final question. When the world needs copper to electrify, and South Australia holds two-thirds of the nation's reserves, is this beginning of a new mining era or just another cycle of hope before the next delay?
