    BMC’s $1B Kudz Ze Kayah zinc-copper project: design and risk lens for engineers

    BMC’s $1B Kudz Ze Kayah zinc-copper project: design and risk lens for engineers

    First reported on MINING.com

    30 Second Briefing

    Drilling at BMC Minerals’ Kudz Ze Kayah project in Yukon has intersected thick, high-grade massive sulphides in the Krakatoa zone, with hole K26-560 cutting 25.1 metres at 180 g/t silver, 9.7% zinc, 1 g/t gold, 0.3% copper and 3.4% lead from 327.5 metres, confirming 2016 intercepts such as 20.8 metres at 218 g/t silver and 8.6% zinc. The project now has positive Yukon and federal decision documents, a 2023 feasibility study outlining a US$835 million pre-tax NPV (7%), 42% IRR, nine-year mine life and US$492 million pre-production capex, but faces continued opposition from Kaska Nation groups over caribou and environmental impacts as BMC targets a final investment decision in late 2027.

    Technical Brief

    • Kudz Ze Kayah’s 2025 indicated resource totals 18.3 Mt at 148 g/t Ag, 6.3% Zn, 1.4 g/t Au, 0.9% Cu, 1.9% Pb.
    • Inferred resources add 0.8 Mt at 143 g/t Ag, 7.2% Zn, 1.2 g/t Au, 1.0% Cu, 1.7% Pb.
    • ABM’s 2023 probable reserve stands at 15.7 Mt grading 138 g/t Ag, 5.8% Zn, 1.3 g/t Au, 0.9% Cu, 1.7% Pb.
    • Contained metals in indicated resources include 87 Moz Ag, 1.1 Mt Zn, 827 koz Au, 164 kt Cu, 346 kt Pb.
    • The 2023 reserve-based estimate for ABM alone contains 70 Moz Ag, 915 kt Zn, 666 koz Au, 136 kt Cu, 266 kt Pb.
    • Current campaign is a 20,000 m drill programme targeting resource and reserve growth around the ABM–Krakatoa area.
    • KZK is permitted through Yukon and federal decision documents following YESAB’s 2020 recommendation and subsequent 2022, 2024 decisions.

    Our Take

    BMC Minerals’ current A$468 million market capitalisation versus the Kudz Ze Kayah pre-tax NPV of US$835 million suggests equity markets are still applying a steep Yukon and permitting discount, leaving room for a potential re-rating if the late-2027 development timeline firms up.

    The A$100 million oversubscribed IPO noted in our December 2025 coverage of BMC Minerals indicates that investors have already signalled strong appetite for Yukon zinc-copper exposure, which may ease future equity raises needed to fund the US$492 million pre-production capex at KZK.

    With Kudz Ze Kayah and Fireweed Metals’ Macpass both zinc-rich projects in Yukon, the combined indicated resources and contained metal in our database point to this territory emerging as one of the more substantial undeveloped zinc districts in recent Mining–Projects coverage.

    MAX Power Mining–Moose Jaw hydrogen MOU: subsurface and capex notes for engineers

    MAX Power Mining has signed an MOU with the City of Moose Jaw, Saskatchewan, to advance natural hydrogen commercialisation in the Regina–Moose Jaw Industrial Corridor, centred on the Lawson Natural Hydrogen system near Central Butte, about 80 km northwest of the city. Core desorption tests from nine samples in Cambrian Basal sands above the Basement Complex discovery returned helium values up to 8.7%, averaging 4.4%, indicating a potentially valuable hydrogen–helium system. The partners aim to leverage existing regional infrastructure and policy support to move the project towards commercial validation.

    Water shortages and mining projects: schedule and design takeaways for engineers

    Water scarcity and multi‑year permitting delays—often two to four years for discharge and dewatering approvals in the western US—are increasingly stalling otherwise bankable mines, with water risk now affecting project schedules, financing and national credit profiles. Consultants such as Woodard & Curran report that “credible water stories” are becoming as critical as ore grades, pushing operators towards closed‑loop recycling and non‑traditional sources. US firms Genesis Systems and Atoco are deploying atmospheric water generation units, including Genesis’ containerised WaterCube systems producing over 1,000 gallons per day off‑grid, now trialled at mine sites.

    Nouveau Monde’s Matawinie graphite mine: capex, schedule and offtake lens for engineers

    Nouveau Monde Graphite has approved construction of the Matawinie open-pit mine in Saint-Michel-des-Saints, Quebec, designed to produce about 106,000 tonnes per year of graphite concentrate over more than 25 years and powered by the provincial hydroelectric grid. The company has secured roughly $644.5 million in equity and debt, with total capex for Matawinie and the Bécancour battery material plant now estimated at about $634 million after downsizing the plant from the 2025 feasibility study. A 30‑month build is planned to reach full production by end‑2028, with 75% of output under offtake, including a seven‑year, 30,000‑t/y fixed‑price contract with the Government of Canada.
