    Sunrise US critical minerals reserve bid: offtake and HPAL notes for engineers

    Sunrise US critical minerals reserve bid: offtake and HPAL notes for engineers

    First reported on Australian Mining

    30 Second Briefing

    Sunrise Energy Metals is positioning its Sunrise nickel–cobalt–scandium project in New South Wales to supply the newly announced US strategic critical minerals reserve, targeting long-term offtake into the American defence and clean energy supply chain. The laterite project is designed around high-pressure acid leach (HPAL) processing of nickel and cobalt, with scandium oxide as a key by-product for high-strength aluminium alloys in aerospace and automotive applications. Any US reserve participation would likely require binding offtake contracts, compliance with US sourcing rules, and investment in export logistics from eastern Australia.

    Technical Brief

    • HPAL flowsheet selection drives requirements for high-pressure autoclaves, acid plants and residue storage facilities.
    • Laterite ore characteristics necessitate detailed geometallurgical modelling to optimise leach conditions and acid consumption.
    • Similar HPAL laterite projects show that commissioning risk and ramp-up timelines are critical to offtake reliability.

    Our Take

    Sunrise Energy Metals’ interest in the US critical minerals reserve aligns with Canberra’s push outlined in the recent Australian Critical Minerals Prospectus, which mapped 49 mining and 29 midstream proposals, signalling that Australian-listed players are positioning to plug both US and domestic supply gaps.

    With both Australia and the United States flagged in this piece, Sunrise’s move suggests it is trying to straddle dual policy frameworks – US strategic stockpiling on one side and Australian critical minerals promotion on the other – which can de-risk offtake but may complicate permitting and funding timelines.

    Critical minerals items in our database often feature Iluka Resources’ Australian projects; Sunrise appearing alongside this theme indicates a widening field of Australian operators seeking to convert policy momentum into concrete contracts, particularly where US-backed reserves or incentives are in play.

    Boliden Somincor–EDP–Greenvolt solar UPAC: integration notes for Neves‑Corvo mine engineers

    Boliden Somincor has partnered with EDP and Greenvolt to build Portugal’s largest self‑consumption solar generation unit (UPAC) near the Neves‑Corvo zinc mine at Castro Verde, supplying power directly to mine operations. The distributed solar plant will sit adjacent to one of Europe’s largest zinc orebodies, reducing grid dependence for high‑load processes such as hoisting, ventilation and paste backfill plants. For mine planners and electrical engineers, the project signals growing integration of large‑scale on‑site renewables into base‑metal underground operations in southern Europe.

    Aramine AutoNav Tele loader at Reward Gold mine: design and safety notes for planners

    RCT – Powered by Epiroc’s AutoNav Tele automation has been fitted to an Aramine L350D loader to support narrow vein stoping at Vertex Minerals’ Reward Gold mine at Hill End, after the unit was commissioned through Epiroc’s Orange Service Centre in New South Wales. The compact L350D, designed for ultra-narrow headings, is now operated via tele-remote AutoNav control rather than line-of-sight, allowing tramming and loading in constrained drives. For geotechnical and mine planners, this enables extraction in thinner ore lenses while keeping operators out of unsupported ground.

    Bosch Rexroth–MEDATech off‑highway electrification: integration notes for mine engineers

    Bosch Rexroth is partnering with MEDATech Engineering to deliver end‑to‑end electrification packages for off‑highway and mining mobile equipment, combining Rexroth’s mobile hydraulics, inverters and controls with MEDATech’s EV drivetrain integration capability. The collaboration targets full systems from componentry and software through to application‑specific design and build, aimed at OEMs and retrofit projects for haul trucks, loaders and other heavy units. For mine operators, this points to more standardised electric powertrain architectures and a clearer route to integrating high‑voltage drivetrains with existing hydraulic and control systems.
