    Brixton’s 5,015 g/t silver at Langis: resource and mine-planning notes for engineers

    Brixton’s 5,015 g/t silver at Langis: resource and mine-planning notes for engineers

    First reported on MINING.com

    30 Second Briefing

    Brixton Metals has reported an exceptional intercept of 20 m averaging 5,015 g/t silver from 165 m downhole in hole LM-26-377 at the brownfield Langis project near Cobalt, including 14 m at 7,150 g/t from 169 m, in ground with no historic stoping. Follow-up holes LM-26-353 and LM-26-352 returned 13 m at 287.8 g/t and 7 m at 275 g/t silver respectively, as part of a 2026 campaign totalling 24,017 m in 105 holes, with up to 60,000 m planned. Mineralisation occurs both in veins and disseminated through host rocks, potentially expanding targets beyond the narrow native-silver veins that characterised historic Cobalt camp mining.

    Technical Brief

    • Mineralisation has been traced for at least 100 m along strike at Shaft 6 Southeast.
    • Shaft 6 Southeast and Shaft 6 South are being drilled to understand structures controlling the highest silver grades.
    • The current 2026 Langis campaign has already completed 24,017 m of core drilling in 105 holes.
    • Brixton plans to extend drilling to as much as 60,000 m at Langis before initial resource definition.
    • Historic Langis mine produced 10.4 Moz silver between 1908–1989 at 20–25 oz/t head grades.
    • Past Langis operators developed over 10 km of underground workings with reported 88–98% silver recoveries.
    • Brixton’s conceptual exploration target is 1–2 Mt grading 400–800 g/t Ag, pending sufficient drilling.
    • Separate drilling of 261 m into historic tailings aims to support a first tailings resource and metallurgical testwork.

    Our Take

    In our database of 1,251 mining stories, very few silver-focused juniors in Canada show conceptual targets as high as the 400–800 g/t range cited for Langis, which signals that Brixton Metals is positioning this as a potential high-margin, small-tonnage underground opportunity rather than a bulk-tonnage play.

    The historic 10 km of underground workings and 88–98% reported recoveries at Langis mean a restart scenario could leverage existing geometry and metallurgical knowledge, shortening study timelines compared with greenfield silver projects in Ontario that lack this level of legacy data.

    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.
