Decmil builds lithium sector with Covalent, Talison

Latest News

Decmil has won two construction contracts to expand its footprint in the Western Australian lithium sector, securing a combined £34 million with Covalent Lithium and Talison Lithium. Wesfarmers subsidiary Covalent will see Decmil design and construct its non-process infrastructure buildings for the Mount Holland lithium project. Talison Lithium requires Decmil to construct a technical services building at the Greenbushes lithium operation.

The Greenbushes construction will include office facilities and a fleet mine control room for truck haulage optimisation. Decmil chief executive officer Dickie Dique said these contracts allowed the company to show off its speciality. "Decmil has a proven track record of successfully delivering non-process infrastructure and building construction contracts in regional areas, and securing these contracts is a reflection of our expertise in this area," he said.

As the lithium price continues to rise, having gained around 80 per cent in 2022, Dique said it was important for Decmil to maintain a presence in this space. "These contracts strategically position Decmil to capture the burgeoning opportunities in the lithium mining and processing sector," he said. "Lithium plays a crucial role in the manufacture of lithium batteries which are so integrsl to the decarbonisation of the global economy, and Decmil is well positioned to support Australia's lithium producers."

Both contracts will begin immediately and will be completed in the first half of 2023. Early mining operations began at Mount Holland in early-2022, courtesy of Thiess, and full production is expected by the second half of 2024. Greenbushes contains the world's largest known and highest grade deposit of lithium mineral spodumene.

The mine's chemical grade plant 2 was restarted in July which took the operation's processing capacity to 1.34 million tonnes per annum of lithium concentrate.
