    Bellevue Gold paste plant: engineered backfill implications for mine planners

    Bellevue Gold paste plant: engineered backfill implications for mine planners

    First reported on Australian Mining

    30 Second Briefing

    Bellevue Gold has approved construction of a paste backfill plant to service the Deacon and Deacon North underground mining areas at its namesake project in Western Australia, aiming to increase ore recovery from pillars and narrow stopes. The plant will use tailings-based paste to fill voids, improving ground support and allowing tighter stope spacing and higher extraction ratios compared with cemented rockfill. For geotechnical and mine planners, the move signals a shift towards engineered backfill to control dilution, manage seismicity and extend mine life in deep, high-grade zones.

    Technical Brief

    • Paste plant will be located on surface adjacent to existing Bellevue process plant footprint.
    • Design will utilise tailings from the current processing circuit, avoiding separate dedicated backfill milling.
    • Plant approval follows recent ramp-up of underground production at Deacon and Deacon North.
    • Backfill strategy is integrated into the updated Bellevue mine plan and long-term scheduling.
    • Capital for the paste plant has been approved within Bellevue’s existing project funding envelope.
    • Adoption of tailings paste aligns with sector move away from surface tailings storage-only strategies.

    Our Take

    Bellevue Gold Limited’s work at Deacon and Deacon North slots into the ‘Projects’ and ‘Sustainability’ cluster that makes up a sizeable portion of the 1989 tag-matched pieces, signalling that Australian underground operators are increasingly framing backfill and tailings decisions as ESG as well as productivity levers.

    Within our 1052 Mining stories, Australian items often highlight paste plants as a way to both stabilise underground stopes and reduce surface tailings footprints, so any recovery uplift at Deacon and Deacon North is likely to be evaluated alongside reduced closure liabilities and permitting risk.

    For Western Australian goldfields operations like Deacon and Deacon North, paste backfill typically enables tighter stope spacing and higher extraction ratios in remnant or narrow-vein areas, which can extend mine life and defer capital for new ore sources even when no headline resource upgrade is announced.

    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.
