Perpetua Resources has signed an agreement with Idaho National Laboratory, operated by Battelle Energy Alliance, to host, commission and run a flexible, modular pilot plant to recover critical and defence-related minerals, including antimony, from Perpetua’s orebodies. The pilot is expected to test flowsheets for selective antimony recovery alongside other strategic elements, using containerised process modules that can be reconfigured for different ore types and chemistries. Outcomes will inform full‑scale processing design for the Stibnite Gold Project and potential US domestic supply chains for military‑grade antimony products.

Aurecon has been appointed Engineering Program Partner for Rio Tinto Iron Ore’s Sustaining Capital teams in Western Australia from October 2025 to October 2028, extending its long-running role on Pilbara brownfield projects. The mandate covers multi‑disciplinary engineering for fixed plant, rail and port assets across RTIO’s iron ore network, including structural upgrades, materials handling improvements and life‑extension works on existing processing infrastructure. For geotechnical and civil teams, the partnership signals continued demand for staged upgrades, brownfield tie‑ins and asset integrity assessments rather than major greenfield expansions.

Iron Mine Contracting has secured a 39‑month mining services contract with Covalent Lithium to deliver drill, blast, load and haul, and run‑of‑mine management at the Mt Holland hard‑rock lithium operation in Western Australia’s Goldfields. The scope covers full open‑pit production support for Covalent’s Mt Holland mine and concentrator, which will feed spodumene concentrate to the company’s Kwinana Refinery now in commissioning. The deal signals long‑term third‑party involvement in both production drilling and material movement at one of Western Australia’s key lithium projects.
