    Thacker Pass capex up to $1.6B: schedule and design notes for mine planners

    First reported on MINING.com

    30 Second Briefing

    Lithium Americas plans 2026 capex of US$1.3–1.6 billion on Phase 1 of the Thacker Pass lithium project in Nevada, with US$1.2–1.5 billion directed to construction and peak on-site employment of about 1,800 skilled workers by year-end. Detailed engineering is 93% complete and procurement 60%, backed by a US$2.23 billion US Department of Energy loan and equity stakes including 38% ownership by General Motors. Phase 1 is scheduled to start producing 40,000 t/y of battery-grade lithium carbonate from late 2027, with full ramp-up through 2028.

    Technical Brief

    • DOE loan of US$2.23 billion is the largest facility the Department has extended to a miner.
    • Loan structure is intended to cover a planned three‑year buildout of Thacker Pass Phase 1.
    • Remaining 2026 capex beyond direct construction is allocated to other capitalised development and DOE interest payments.
    • US government has taken a 5% equity stake in Lithium Americas and 5% directly in Thacker Pass.
    • General Motors holds a 38% equity interest, aligning mine output with downstream EV battery demand.
    • Thacker Pass is positioned as the Western Hemisphere’s largest lithium source, exceeding Albemarle’s Silver Peak output.
    • Nameplate 40,000 t/y lithium carbonate capacity equates to supply for roughly 800,000 electric vehicles per annum.
    • Strengthening lithium market conditions are timed with late‑2027 commissioning and 2028 production ramp‑up, reducing price risk.

    Our Take

    With Albemarle idling its Kemerton lithium hydroxide plant in Western Australia, Thacker Pass in Nevada stands out in our database as one of the few large-scale lithium builds advancing in an environment where some incumbents are curbing conversion capacity.

    The combined 5% US government stake in Lithium Americas and in Thacker Pass, alongside the DOE’s multi‑year loan, effectively anchors this Nevada lithium project within US industrial policy in a way not seen in other recent lithium items in our coverage, which more often feature Chilean or Australian state involvement.

    General Motors’ 38% project stake gives an automaker unusually deep exposure to upstream lithium in North America, contrasting with other lithium stories in our database where OEMs typically rely on offtake or supply agreements rather than embedded project ownership.

    Thiess adds fourth Liebherr R 9800 at Lake Vermont: fleet and productivity notes for engineers

    Thiess has mobilised a fourth Liebherr R 9800 hydraulic excavator to Jellinbah Group’s Lake Vermont coal mine in Queensland, expanding a fleet already built around ultra-class loading units. The R 9800, typically paired with 220–300 t class haul trucks and capable of 40–80 m³ bucket capacities depending on configuration, is being deployed to meet rising production requirements and tighten truck–shovel match. The move signals continued capital commitment to high‑productivity primary loading assets and supports longer-term planning for efficient strip mining and overburden removal.

    Finning–McCloskey 10,000th Cat engine: fleet planning notes for plant engineers

    Finning UK & Ireland has supplied its 10,000th Cat® industrial engine to McCloskey International, extending a supply partnership that began in 2006 when McCloskey established manufacturing in Northern Ireland. The engines power McCloskey’s mobile crushing, screening and material handling equipment, which is seeing rising global demand in aggregates and mining applications. For plant operators, the milestone signals long-term parts and service continuity for Cat-powered McCloskey units, an important factor in lifecycle planning and fleet standardisation.

    Glencore Sudbury INO mine rescue win: training takeaways for deep nickel operations

    Glencore’s Sudbury Integrated Nickel Operations (INO) mine rescue team has taken the 2026 Ontario Mine Rescue overall champion title in Sudbury, outperforming seven other regional winners in a province-wide final. The team completed a complex mock underground emergency scenario designed by Ontario Mine Rescue (OMR), typically involving live-fire suppression, casualty extrication and use of closed-circuit breathing apparatus under time and communication constraints. For mine operators, the result reinforces the value of rigorous, scenario-based training regimes and standardised emergency procedures across multi-level, deep nickel operations.
