    Larvotto’s Blockade copper mine option: resource and processing lens for engineers

    First reported on Australian Mining

    30 Second Briefing

    Larvotto Resources has exercised its option over the historical Blockade copper mine northeast of Mount Isa after confirmatory reverse circulation drilling beneath the old open pit returned 31m at 1.16 per cent copper from 63m. Eight RC holes were completed to validate historical data before proceeding, with resource definition drilling scheduled to start in the September quarter. A maiden JORC resource estimate is planned, signalling potential for near-surface sulphide mineralisation that could be integrated with existing Mount Isa processing infrastructure.

    Technical Brief

    • Drilling targeted mineralisation directly beneath the existing Blockade open pit, indicating potential pit-deepening scenarios.
    • Historical status of the Blockade mine suggests existing surface disturbance and partial mining infrastructure for potential reuse.
    • RC drilling beneath a legacy pit reduces sterilisation risk and focuses spend on confirmed mineralised trends.

    Our Take

    With only a handful of copper‑tagged items in our recent mining coverage featuring both near‑surface grades above 1% and brownfields settings like Mount Isa, Blockade could offer Larvotto a relatively low‑capex, quick‑turn addition to its Queensland copper pipeline.

    Larvotto’s existing mine‑gate offtake with Glencore from Hillgrove suggests that, if Blockade advances, the company may be able to leverage established relationships with major processors in the region to de‑risk future copper concentrate marketing from Mount Isa.

    Geopolitical risk and private capital flows: gold price signals for mine planners

    Growing geopolitical tensions are pushing capital out of sovereign bonds and into private assets, a rotation market-cycle analyst Martin Armstrong links to a potential renewed gold rally from Q1 next year. Armstrong sees Europe as particularly exposed, arguing EU states face rising war-related borrowing costs and inflation as “war drums” lift long-term rates, while bond markets “give us the real story”. He warns that if gold closes below $4,000/oz weekly it could test $3,500–$3,700, but expects elections in the US, Israel and Ukraine to keep geopolitical risk elevated and ultimately drive prices higher.

    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.
