    Perpetua’s tungsten find at Stibnite: pit expansion and resource notes for mine planners

    First reported on MINING.com

    30 Second Briefing

    Perpetua Resources has reported a new gold‑tungsten discovery and multiple high‑grade gold intercepts between the Yellow Pine and West End reserve pits at its Stibnite gold‑antimony project in central Idaho, including scheelite-bearing intervals in the Clark Tunnel Fault Zone on the southeastern edge of the proposed Yellow Pine pit. Widely spaced drilling at the adjacent Huckleberry Fault Zone has outlined over 100 metres in width and 0.5 km of strike of gold mineralisation, while Hangar Flats drilling returned additional high‑grade gold plus antimony‑tungsten intercepts. The company aims to use these targets to extend pit limits and potentially grow beyond the current 3.1 Moz indicated and inferred gold and 99.8 Mlb antimony resources outside reserves, though work beyond the permitted plan may trigger further regulatory review.

    Technical Brief

    • Perpetua is targeting extensions within three already permitted open pits at the Stibnite Gold project.
    • CEO states drilling is sequenced to align with the current mine plan, not greenfield step-outs.
    • Company aims to sustain or exceed 463,000 oz/y gold beyond the first four production years.
    • Tungsten identification is via scheelite occurrences, implying potential by-product recovery from existing pit envelopes.
    • HFZ mineralisation is defined by widely spaced drilling plus surface sampling over a 0.5 km strike.
    • Hangar Flats NDMEA drilling is explicitly split between high-grade gold targeting and critical-mineral (Sb-W) targeting.
    • Any mining or drilling outside the currently permitted project scope will trigger additional regulatory review processes.

    Our Take

    Perpetua Resources’ new tungsten angle at Stibnite in Idaho slots into our 431 keyword‑matched pieces on gold and tungsten, but it is one of very few US‑based items combining both commodities at a single asset, which may strengthen its case as a multi‑critical‑mineral hub in permitting and funding discussions.

    With China accounting for 80% of global tungsten production and the US Army already backing Perpetua’s antimony pilot plant at Idaho National Laboratory (30 July 2026 article), any economically viable tungsten at Stibnite would likely deepen US defence‑sector interest in the project’s offtake and processing routes.

    McEwen’s $55M Ontario asset sale: production growth lens for mine planners

    McEwen has agreed to sell its Fuller and Paymaster gold properties in Ontario’s Timmins district to Discovery Mining for $55 million in cash and stock, freeing capital to push a production target of 250,000–300,000 gold-equivalent ounces per year by 2030. The deal covers 210 hectares at Fuller, a 60% stake in the 179-hectare Paymaster property, and associated surface rights, consolidating Paymaster under Discovery’s Dome Mine subsidiary. Proceeds will be reinvested into the Fox Complex (Froome, Stock, Grey Fox), Nevada’s Gold Bar Complex, and Mexico’s El Gallo build, with Stock Mine slated for first ore in Q4 2026 and commercial output in Q1 2027.

    Lithium Triangle extraction hurdles: hydrogeological insights for project teams

    South America’s Lithium Triangle holds about 64 million tonnes of identified lithium resources (43% of the global 150 million tonnes), yet geologist José Cabello’s review of 43 salt flats across Argentina, Bolivia and Chile shows that variable brine chemistry, impurities and groundwater behaviour make recovery and costs highly site-specific. Salar de Atacama benefits from ultra‑dry climate, relatively clean brines and strong logistics, while other basins such as Altoandinos, Pedernales, Hombre Muerto Oeste, Rincón, Sal de los Ángeles and Sal de Vida face tighter water and hydrogeological constraints. Direct lithium extraction (DLE) could unlock lower‑grade or impurity‑rich brines, but Cabello stresses that trade‑offs between brine withdrawal and freshwater consumption mean technology selection must be tailored to each basin’s hydrology and ecosystem.

    KGHM’s $2.4bn copper projects fast-tracked: CRMA implications for mine planners

    EU regulators have granted strategic status under the Critical Raw Materials Act to KGHM’s 9.5‑billion‑zloty ($2.44bn) Retków‑Grodziszcze mine and Legnica smelter conversion, unlocking faster permitting, streamlined administration and access to preferential financing. Retków‑Grodziszcze is planned to deliver over 100 million tonnes of ore by 2055, yielding about 1.5 million tonnes of copper and 5,000 tonnes of silver, while Legnica’s recycling line targets 135,000 tonnes of electrolytic copper and 250 tonnes of nickel per year. The move materially boosts EU copper and nickel recycling capacity, central to the CRMA’s 25% recycling target.
