BHP awards Olympic Dam expansion contract

Olivia Thomson February 3, 2025

BHP has awarded a contract worth approximately $40 million to support the proposed expansion of its Olympic Dam copper smelter and refinery facilities in South Australia.


A joint venture between Fluor Australia and Hatch have been granted the engineering, procurement and construction management (EPCM) contract following engagement with BHP’s major projects, procurement, commercial and Copper South Australia teams.

The contract will be executed in stages as BHP progresses towards a final investment decision on the smelter and refinery expansion, which is expected in the first half of the 2026–27 financial year (FY27).

“Fluor and Hatch are experienced global EPCM partners with significant shared experience in delivering mega projects, who will bring the right level of scale and expertise to help BHP progress its copper growth plans in South Australia,” BHP Group procurement officer Rashpal Bhatti said.

“The growth potential for Copper SA is exciting and this first stage of EPCM works will be key as we progress the proposal for an expanded copper smelter and refinery at the heart of South Australia’s growing copper province towards a final investment decision.”

Last September, BHP outlined how it plans to potentially double its copper production in South Australia over the next decade.

The Big Australian would introduce a phased approach to increase refined copper cathode production to 500,000 tonnes (t) annually by the early 2030s, with a possible boost to 650,000t by the mid-2030s. This would be a significant jump from the approximately 322,000t produced in FY24.

Phase one of the strategy would involve upgrading the existing copper smelter and refinery at Olympic Dam to a two-stage smelter and extension of refinery facilities, with a capacity to produce more than 500,000t per year.

“It is critical that we prudently manage our spending to achieve the vision that BHP shares with many others to grow copper production in South Australia, and we have worked closely with Fluor and Hatch on a contract structure that supports this,” Bhatti said.

BHP’s Copper South Australia business comprises Olympic Dam, the Carrapateena and Prominent Hill mines, and the Oak Dam deposit, the latter of which has 13 rigs currently carrying out exploration in a bid to advance its studies.

“BHP is building momentum in South Australia, and this is another step forward in our strategy to increase the production of SA’s high-quality copper resources to support the global energy transition,” BHP asset president Copper SA Anna Wiley said.

“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.”

La géologie de la mine de de Olympic Dam est très particulière, avec de l'Uranium dans le cuivre et l'or, ce qui est rare sur la planète.

Cuivre : Méga fusion à venir entre les géants miniers Anglo American et Teck

Les géants miniers Anglo American et Teck ont annoncé, mardi 9 septembre dans la matinée, une «fusion entre égaux» visant à créer l'un des plus grands producteurs de minerai de cuivre du monde. L'opération vient après de nombreuses tentatives de giga-rachat dans le secteur sur fond de ruée vers le métal rouge, star de la transition énergétique.

Anglo American, Teck Resources to merge in second-largest mining deal ever

By Clara Denina September 9, 2025

London-listed miner Anglo American (AAL.L), opens new tab and Canada's Teck Resources (TECKb.TO), opens new tab plan to merge, the two companies said on Tuesday, marking the sector's second-biggest M&A deal ever and forging a new global copper-focused heavyweight.
Under the proposed deal, which will require regulatory approvals, Anglo American shareholders would own 62.4% of new company Anglo Teck, while shareholders in Teck would hold 37.6%.
Anglo Teck will be headquartered in Canada but have a primary stock listing in London, said the two companies, whose combined market capitalisation exceeds $53 billion.

The deal to form the world's fifth-largest copper company is also a big bet on copper by Anglo. Glencore's (GLEN.L), opens new tab $90 billion merger with Xstrata in 2013 remains the largest mining deal in history.
Copper, used in the power and construction sectors, is set to benefit from burgeoning demand spurred by electric vehicles and artificial intelligence.
Miners have raced to develop new projects and there have been a flurry of takeover bids, though no major acquisition has so far succeeded.
