    Sandfire drilling ramp-up at Kalkaroo: pit design and PFS insights for mine planners

    First reported on Australian Mining

    30 Second Briefing

    Sandfire Resources has begun a major drilling campaign at the Kalkaroo copper–gold project in South Australia, targeting one of the country’s largest undeveloped open-pit copper–gold deposits ahead of a planned pre-feasibility study. The programme starts with a first drill rig already on site and additional rigs to follow, aimed at tightening resource definition and testing extensions around the proposed pit shell. Results will directly inform geotechnical design parameters, pit slope optimisation and mine scheduling for the forthcoming PFS.

    Technical Brief

    • Sandfire Resources is operator, progressing Kalkaroo as a large-scale open-pit copper–gold asset.
    • Site is located in South Australia, implying design under that jurisdiction’s mining and environmental regulations.
    • Early drilling mobilisation via a single rig suggests staged ramp-up and progressive data acquisition.
    • LinkedIn was used for disclosure, indicating near real-time communication of drilling progress and key intercepts.
    • Characterisation of Kalkaroo as “one of Australia’s largest undeveloped” deposits flags potential multi-decade mine life planning.
    • Scale of the undeveloped resource implies future requirements for large pit slope heights and complex geotechnical zoning.

    Our Take

    Our database shows Sandfire Resources has been advancing copper assets on three continents – Motheo in Botswana, Black Butte in the US and now Kalkaroo in South Australia – signalling a portfolio strategy that balances jurisdictional risk across Africa, North America and Australia.

    The earlier definitive agreements with Havilah Resources giving Sandfire a pathway to 80 per cent of Kalkaroo suggest this ramp‑up in drilling is likely aimed at quickly converting and optimising the copper–gold resource base ahead of any major development decision.

    Sandfire’s use of a 21 MW leased solar plant at Motheo indicates that any eventual development concept at Kalkaroo in South Australia may face internal pressure to incorporate similar low‑carbon power solutions to keep operating costs and emissions competitive with its other copper operations.

    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.
