    Kathleen Valley expansion: early works and procurement lessons for mine planners

    April 29, 2026|

    Reviewed by Tom Sullivan

    First reported on International Mining – News

    30 Second Briefing

    Early works and long‑lead procurement have started for Liontown Limited’s planned expansion of the Kathleen Valley Lithium Operation in Western Australia, ahead of a formal Final Investment Decision targeted for the end of Q1 FY2027. The programme covers critical items and packages whose fabrication and delivery times could otherwise delay ramp‑up of the underground mine and processing plant. Early commitment to these components signals a push to lock in key OEM capacity and manage schedule risk in a tight lithium project pipeline.

    Technical Brief

    • OEM engagement is being advanced under pre-FID arrangements to secure manufacturing slots and delivery windows.
    • Procurement strategy is structured to allow deferral or reallocation if FID timing or scope changes.
    • Contracting for early works is expected to use discrete packages to maintain competitive tension and flexibility.

    Our Take

    Our database shows multiple recent items on Liontown’s Kathleen Valley Lithium Operation, including a 150,000 wmtpa 2027–28 offtake with Canmax Technologies, signalling that the current expansion works are being sequenced against already-contracted downstream demand rather than purely speculative capacity growth.

    With lithium among the more frequently tagged commodities in our recent Mining/Projects coverage, Kathleen Valley’s expansion out to end of Q1 FY2027 positions Liontown as one of the few developers still committing to a defined growth timetable despite price volatility, which may pressure higher-cost or less-advanced hard‑rock projects.

    The earlier report on ball mill procurement for Kathleen Valley highlights that long‑lead grinding equipment is being locked in ahead of broader construction, reducing schedule risk but also front‑loading capex exposure if lithium market conditions soften before FY2027 ramp‑up.

    Metals Australia’s $2.05B Baie‑Comeau graphite refinery: project and IRR lens for engineers

    Metals Australia plans a C$2.05 billion high‑purity graphite refinery near Baie‑Comeau, Quebec, designed to process 75,000 tonnes per year of flake graphite concentrate into 51,000 tonnes of battery‑grade products over a 25‑year life, with a projected 25.6% internal rate of return and 227 permanent jobs. Feedstock will come from its Fermont project averaging 10.2% graphite, about 2.4 times higher grade than publicly reported for Nouveau Monde Graphite, and the site leverages rail‑ferry links plus a deep‑water port. The company will bypass a traditional PFS, moving directly to final feasibility while running parallel community and Indigenous engagement to meet Canada’s 2040 graphite mine and refinery targets.

    Ur-Energy’s Shirley Basin uranium start-up: ISR project metrics for mine planners

    Ur-Energy has begun in situ recovery uranium production from Mine Unit 1 at its Shirley Basin project in Wyoming, capturing uranium-bearing solution following completion of wellfield installation, processing circuits and permitting. The project has licensed annual wellfield and toll-processing capacity of up to 2.0 million lb U₃O₈ equivalent, with 9.1 million lb U₃O₈ in Measured and Indicated resources at an average 0.22% eU₃O₈ and an anticipated nine-year mine life across three shallow units. Uranium is loaded onto ion exchange resin on site and is expected to be trucked to the Lost Creek plant for final processing, drying and packaging from this summer, pending a further regulatory inspection.

    Kodiak–Teck Arizona copper explorer: project scale, funding and drill-readiness for engineers

    Kodiak Copper and Teck Resources are combining their Mohave and Copper Hill Arizona porphyry projects into Kay Copper via a three-cornered amalgamation, each receiving 20 million Kay Copper shares at C$0.25 and ending with 28% ownership apiece of an expected 70.3 million-share vehicle. Kay Copper plans a TSXV listing backed by a C$4 million subscription receipt financing at C$0.25 and a C$830,000 private placement at C$0.10, leaving legacy Kay shareholders with 9% and new investors with 35%. Mohave (17 km², last drilled 2011) and Copper Hill (35 km², three mapped porphyry centres) are both drill-ready with multiple untested geochemical and geophysical targets.
