    US lithium miner’s $571M SPAC deal: McDermitt project economics for engineers

    First reported on MINING.com

    30 Second Briefing

    US lithium developer HiTech Minerals will go public on Nasdaq via a $571 million merger with SPAC Constellation Acquisition Corp. I, creating US Elemental, with parent Jindalee Lithium expected to retain about 80% ownership and the new ticker “ULIT”. The key asset is the McDermitt project on the Oregon–Nevada border, holding 21.5 million tonnes LCE and scoped in a 2024 PFS for 47,500 t/y output in the first decade, 63-year mine life, $3.2 billion post-tax NPV (8%), 17.9% IRR and roughly $3 billion capex. Designated under FAST‑41 and backed by a planned $20–30 million raise, the listing aims to secure US capital and partners for McDermitt and the Clayton North project in Nevada amid a lithium price rebound of nearly 40% this year.

    Technical Brief

    • McDermitt resource is stated at 21.5 Mt lithium carbonate equivalent, supporting a 63‑year mine plan.
    • 2024 pre‑feasibility work indicates first‑decade production averaging 47,500 t/y of lithium carbonate equivalent.
    • Project economics quote a post‑tax NPV8 of $3.2 billion and an internal rate of return of 17.9%.
    • Initial development capital for McDermitt is estimated at about $3 billion, excluding later sustaining capital.
    • US Elemental will also consolidate the Clayton North lithium project in Nevada under the same corporate vehicle.
    • Antarctica Capital plans to contribute $4 million into a broader $20–30 million project advancement equity raise.

    Our Take

    With lithium prices up nearly 40% this year in the article’s timeframe, long‑life US assets like McDermitt in Oregon/Nevada tend to attract strategic offtake or JV interest in our database, particularly from OEMs seeking IRA‑compliant supply rather than pure financial investors.

    Jindalee’s expected ~80% rollover ownership in US Elemental after the SPAC deal is unusually high compared with other mining M&A items in our coverage, signalling that the listing is more about accessing US capital pools for a domestic lithium project than about ceding control.

    Integrated Pump Technology in Central Africa: dewatering design notes for mine engineers

    Integrated Pump Technology is expanding dewatering support in Central Africa’s mines as more erratic, climate-driven rainfall increases pit flooding and sump inflows, deploying Grindex submersible units and Godwin diesel-driven surface pumps for both open-pit and underground operations. The company is pairing high-solids, high-head pump selections with local distributor partnerships and on-site application audits to match pump curves to specific shaft depths, static heads and slurry loadings. For mine operators, the focus is on maintaining pumping capacity during peak storm events and reducing unplanned downtime from flooded haul roads, declines and pump chambers.

    Sandvik Rock Processing Reborn in Africa: retrofit economics for mine engineers

    Sandvik Rock Processing’s Reborn programme is gaining uptake at African mines and quarries seeking higher throughput from existing primary and secondary crushers while limiting capex. The scheme replaces ageing crusher cores with new Sandvik units in the original frames and foundations, allowing plants to retain chutes, civils and conveyors while upgrading to current crusher technology and automation. PC Kruger, Business Line Manager Crushing, positions Reborn as a step beyond standard refurbishment, targeting faster installation, reduced downtime and predictable lifecycle costs.

    Cementation Africa in deep underground mining: design and risk insights for engineers

    Africa’s push into deeper, more complex underground orebodies is driving demand for specialist contractors such as Cementation Africa, which combines shaft sinking and raiseboring capability with in‑house engineering and risk management. The contractor is focusing on technically challenging work, including high-stress rock mass conditions, complex ground support regimes and critical‑path access infrastructure for new critical minerals projects. For mine owners, the key shift is from pure construction procurement to integrated delivery models where design, construction methodology and risk allocation are tightly coupled.
