    Alkane extends gold–antimony system at Nagambie: design and geotech notes for mine planners

    Alkane extends gold–antimony system at Nagambie: design and geotech notes for mine planners

    First reported on Australian Mining

    30 Second Briefing

    Alkane Resources has extended the known gold–antimony mineralised system at its Nagambie project in Victoria, with initial drilling intersecting high-grade mineralisation 115m below the previously defined limit. The latest holes confirm vertical continuity of the system and identify broader mineralised zones with estimated true widths up to 32m, suggesting thicker, potentially bulk-mineable intervals. For resource modellers and geotechnical planners, the deeper, wider zones will affect pit–underground transition assumptions, stope design and ground support requirements as drilling advances.

    Technical Brief

    • Diamond drilling at Nagambie targets the gold–antimony system at depth beneath existing workings.
    • High-grade intersections are associated with sulphidic, structurally controlled zones typical of orogenic gold–stibnite systems.
    • Broader mineralised intervals imply potential for wider stopes, affecting dilution assumptions and ground support layouts.
    • Deeper intercepts will require updated geotechnical domains, including stress regime and rock mass characterisation at new levels.
    • Antimony association introduces metallurgical complexity, influencing processing route selection and concentrate marketing strategy.
    • Step-out drilling geometry will drive future drill platform locations, collar spacing and underground access development concepts.
    • For similar Victorian orogenic systems, such depth extensions often trigger re-optimisation of pit shells and underground cut-off grades.

    Our Take

    Alkane Resources is emerging as one of the more active Australian gold–antimony players in our database, with Nagambie in Victoria complementing its work on a new high‑grade zone at the Costerfield gold–antimony mine reported on 24 August 2026, suggesting a deliberate build‑out of expertise in this specific metal pairing.

    The extension of the Nagambie system in Victoria gives Alkane geographic diversification from its deeper gold–copper drilling at Peak Hill in New South Wales (15 October 2026 article), which can help balance exploration risk between shallow, structurally complex antimony‑rich systems and very deep copper–gold targets.

    With Larvotto Resources restarting Hillgrove as a gold–antimony operation in New South Wales (1 September 2026), Alkane’s Nagambie work adds to a small but growing cluster of Australian gold–antimony projects in our coverage, which may strengthen the case for shared processing know‑how and potentially regional offtake interest in antimony from Victoria and NSW combined.

    Vulcan Elements–North Carolina rare earth magnets: design and supply notes for engineers

    Vulcan Elements has partnered with the North Carolina Collaboratory and UNC-Chapel Hill chemist Yosuke Kanai to use quantum-mechanical simulations to predict how atomic-level changes affect rare earth magnet properties, backed by a $600,000 research award. The work feeds directly into Vulcan’s 1.1 million-square-foot Benson, North Carolina plant, designed for 10,000 t/y of magnet production and billed as the largest rare earth magnet factory outside China. Vulcan claims its material, technology, software, IP and ownership are fully decoupled from Chinese supply chains, aligning with its existing $1.4 billion US government-backed partnership with ReElement Technologies.

    Northern Star KCGM expansion: commissioning timeline and capacity cues for engineers

    Northern Star Resources has completed the tie-in of its expanded KCGM processing plant in Western Australia, with commissioning of the integrated circuit now under way ahead of a planned production ramp-up in the second half of FY27. Early commissioning is focused on achieving stable, sustained operating conditions across the enlarged plant, rather than immediate throughput gains. For plant and process engineers, the timeline signals when additional milling, crushing and gold recovery capacity at KCGM is expected to start contributing materially to output and unit cost performance.

    Regis Resources and McPhillamys: funding optionality and schedule signals for engineers

    Regis Resources ended the September quarter with $1.28 billion in cash and bullion after generating $265 million in operating cash flow and collecting a $51 million break fee from Vault Minerals, following its decision not to match Genesis Minerals’ competing offer. The strengthened balance sheet gives Regis substantial optionality on funding the McPhillamys gold project in New South Wales, rather than relying heavily on project finance or equity. For mine planners and project engineers, this signals potential acceleration of McPhillamys approvals, early works and long-lead procurement once a final investment decision is made.
