    Alkane’s Kendal antimony-gold hits: mine planning and geotechnical notes

    Alkane’s Kendal antimony-gold hits: mine planning and geotechnical notes

    First reported on Australian Mining

    30 Second Briefing

    Alkane Resources has reported multiple high‑grade antimony–gold intercepts at the Kendal prospect, adjacent to the Youle lode at its Costerfield operation in central Victoria, signalling a potentially significant extension of the narrow-vein system. The discovery targets antimony, a critical mineral used in advanced military and defence applications, alongside high-value gold grades typical of Costerfield-style mineralisation. For mine planners and geotechs, the proximity to existing Youle infrastructure suggests scope for incremental underground development and resource expansion rather than a greenfield build.

    Technical Brief

    • Antimony association implies complex metallurgy, likely requiring continued use or adaptation of existing Costerfield processing flowsheet.
    • High antimony content flags possible deleterious-element constraints for conventional gold circuits if not carefully managed.

    Our Take

    Antimony appears in only a small subset of the 359 keyword-matched pieces in our database, so Alkane Resources’ Kendal results stand out in Australia, where most recent precious-metal coverage is dominated by gold-only plays.

    High-grade antimony-gold intersections comparable to those at Mandalay’s Costerfield operation typically underpin narrow-vein underground mining with complex metallurgy, which can favour smaller but very high-margin operations if processing routes are optimised.

    Within the 1088 Mining stories and 1995 Projects-tagged pieces, Australian antimony projects are relatively scarce, suggesting that any economically robust antimony-gold resource at Kendal could attract strategic interest from offtakers looking to diversify supply away from China-dominated sources.

    EGA–Century Aluminium US smelter JV: capacity, schedule and risks for engineers

    Emirates Global Aluminium and Century Aluminum will build Oklahoma Primary Aluminum, a 750,000‑tonne‑per‑year smelter at Inola that will more than double current US primary aluminium output and be the first new US smelter since 1980. EGA will hold 60% of the joint venture and Century 40%, with construction targeted to start by end‑2026 and first metal by around 2030, creating 4,000 construction and 1,000 permanent jobs. US Aluminum is separately evaluating a co‑located fabrication plant to convert liquid metal into products for electrical, defence, aerospace, automotive and machinery applications.

    WA Mining 2026: programme focus and planning notes for mine engineers

    Tickets are now on sale for the 2026 WA Mining Conference & Exhibition in Perth, following a record 2025 event that drew strong attendance from mine operators, OEMs and METS suppliers across Western Australia’s iron ore, gold and battery minerals sectors. The 2026 program is expected to again focus on automation, decarbonisation and electrification of haulage and processing fleets, alongside data-driven mine planning and remote operations. For engineers, the event offers concentrated access to equipment demonstrations, brownfield upgrade case studies and regulatory updates relevant to WA’s large-scale open-pit and underground operations.

    Aeris profit jumps 62%: Tritton copper output and capex signals for mine planners

    Aeris Resources has reported a 62 per cent jump in first-half FY26 net profit to $25.6 million, with cash on hand rising to $87.9 million, driven by stronger copper output and prices from its Tritton operations in New South Wales. Group copper production reached 13,000–14,000 tonnes for the half, with all-in sustaining costs held near prior-period levels despite higher development spend at Tritton’s Budgerygar and Avoca Tank underground mines. The stronger balance sheet gives Aeris more room to fund mine-life extension drilling and incremental plant upgrades without relying on new debt.
