    Sunday Creek shallow antimony: design and sequencing notes for mine planners

    Sunday Creek shallow antimony: design and sequencing notes for mine planners

    First reported on Australian Mining

    30 Second Briefing

    Drilling at Southern Cross Gold Consolidated’s Sunday Creek project in Victoria has intersected high‑grade antimony directly above the planned exploration decline at the Golden Dyke prospect, confirming shallow critical mineral potential in the upper epizonal system. Six recent holes targeted the upper structural levels where antimony is expected to concentrate, complementing existing gold mineralisation and supporting a combined gold–antimony development concept. For mine planners and geotechnical teams, shallow antimony zones above decline infrastructure may influence decline alignment, ground support design and sequencing of early development headings.

    Technical Brief

    • New intersections confirm antimony-rich zones are vertically stacked above previously defined gold-dominant mineralisation.
    • Structural targeting focused on upper-level vein and breccia systems interpreted from earlier deeper drilling and mapping.
    • Geometry of the antimony lodes will now be modelled explicitly to refine three-dimensional resource wireframes.
    • Shallow intercepts allow potential early antimony development without materially extending decline length or depth.
    • Geotechnical domains in the upper system may differ from deeper gold zones, requiring separate design parameters.
    • Metallurgical flowsheet studies must now consider optimising recoveries for a combined gold–antimony concentrate.

    Our Take

    Sunday Creek appears multiple times in our database as one of the few Victorian projects explicitly framed around both gold and antimony, signalling that Southern Cross Gold Consolidated is positioning it as a critical minerals play rather than a pure gold story.

    The earlier coverage of PYBAR Mining Services starting the exploration decline at Sunday Creek suggests these six new holes at Golden Dyke can be rapidly followed up from underground, shortening the cycle between surface targeting and high-confidence resource definition.

    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.
