Worley secures BHP EPCM mandate for Copper South Australia expansion
Worley Limited (ASX: WOR) has been awarded contracts by BHP to provide study and engineering, procurement and construction management (EPCM) services for expansion projects at Olympic Dam and Carrapateena, part of BHP’s Copper South Australia growth plans.
Announced on 7 September 2026, the mandate covers two of BHP’s key copper assets. Critically, both projects remain subject to final investment decision (FID) by BHP, a qualifier that tempers near-term certainty on full project value.
Worley has confirmed that initial EPCM services have already commenced for early-phase activities. The award positions the company deeper into copper, a market it identifies as a priority within the energy transition.
Neither the contract value nor the duration was disclosed in the announcement.

What the contracts cover
Worley will deliver study and EPCM services concurrently across multiple project phases. The scope spans two workstreams:
-
Olympic Dam — study and EPCM services for potential block cave development and associated infrastructure.
-
Carrapateena — potential expansion of underground operations and processing infrastructure.
The company will provide full delivery and technical expertise through the following model:
-
An Australia-based team leading delivery.
-
Support from industry-leading specialist engineering service providers.
-
Worley’s Global Integrated Delivery team.
-
Additional support from China and Chile.
The award reinforces Worley’s capability in major-project delivery across underground mining and processing.
Why copper matters for the Worley investment case
EPCM stands for engineering, procurement and construction management. Under this model, a company manages the design, sourcing of materials, and oversight of construction across a project’s lifecycle. Because the work is delivered across multiple phases rather than as a single handover, it tends to generate service-based revenue over an extended period rather than a one-off payment.
BHP’s expansion plans are driven by growing copper demand, which the company attributes to electrification and the energy transition. Worley continues to position itself around energy transition materials as a priority growth market, and exposure to copper ties a portion of its revenue to this structural demand theme.
CEO commentary
Chris Ashton, Chief Executive Officer, Worley
“This contract reflects Worley’s continued focus on energy transition materials, such as copper, as a priority growth market. We are pleased to provide ongoing support for BHP’s ambition to grow its copper production in South Australia.”
“Our team brings experience in underground mining, processing and major project delivery, and we look forward to working with BHP and the local businesses in South Australia to progress these mega projects.”
What it means for investors and what comes next
The award presents a two-sided picture for investors. On one side, EPCM work has already commenced for early-phase activities, providing near-term engagement. On the other, full project value remains contingent on BHP reaching final investment decisions on the expansions.
| Factor | Detail |
|---|---|
| Contract awarded | Study + EPCM, Olympic Dam & Carrapateena |
| Status | Subject to BHP final investment decision |
| Work underway | Initial EPCM for early-phase activities |
| Strategic theme | Copper / energy transition materials growth |
| Value / term | Not disclosed |
The key milestone to watch is BHP’s final investment decisions on the Olympic Dam and Carrapateena expansions, which would determine the extent of Worley’s involvement. For now, the award deepens Worley’s alignment with the copper and energy-transition thesis it has flagged as a growth priority.

A final investment decision by the project owner is the pivotal conversion event that transforms preliminary EPCM work into committed, large-scale execution; Worley experienced this directly when Venture Global’s FID on the CP2 LNG project in March 2026 converted planning services into full project execution.
