    AXT’s ECORE LIBS at Hillgrove: rapid core scanning insights for mine planners

    First reported on International Mining – News

    30 Second Briefing

    AXT has supplied Larvotto Resources with Australia’s first onsite Elemission ECORE LIBS rapid core scanner, installed at the Hillgrove antimony-gold project in New South Wales after trials in AXT’s Automated Mineralogy Incubator. The ECORE system provides near real-time, laser-induced breakdown spectroscopy analysis of drill core, enabling faster geochemical characterisation than traditional laboratory assays. For geologists and mine planners, this should tighten turnaround on resource modelling and metallurgical domaining, particularly for complex antimony-gold mineralisation.

    Technical Brief

    • LIBS scanning supports spatially continuous geochemical profiles along core, improving resolution over discrete sample intervals.
    • Immediate elemental data can be integrated with structural logging to refine antimony–gold vein and alteration models.
    • Onsite scanning enables rapid feedback into drill targeting, potentially shortening decision loops between drill phases.
    • For complex polymetallic systems, similar LIBS platforms could reduce dependency on long-turnaround multi-element assay suites.

    Our Take

    Antimony appears in only a small subset of the 112 keyword-matched pieces in our database, so Larvotto Resources deploying advanced core scanning at Hillgrove positions this as one of the more technology-forward antimony-gold projects in Australia.

    Among the 360 Mining stories, onsite analytical tools like LIBS are more commonly reported at large gold operations; seeing this at a project stage asset suggests juniors are now using high-resolution geomet data earlier to tighten drilling spend and shorten study timelines.

    For Australian antimony-gold projects, rapid core characterisation can be strategically important because antimony metallurgy and deleterious element control often drive processing route selection and permitting narratives, not just headline gold grades.

    Suncor Cat AHS at Mildred Lake and Komatsu Mud Mode: integration notes for mine planners

    Suncor has commissioned its first Autonomous Operating Zone at Syncrude’s Mildred Lake oil sands mine, extending its autonomous haulage system deployment beyond the existing fleet of about 140 autonomous trucks already running at other Suncor sites. The new zone uses Cat AHS fleets under Suncor control (since late 2021) and is complemented by Komatsu AHS trucks at Base Plant operating with a dedicated “Mud Mode” to maintain traction and control in soft ground. For mine planners, this signals wider-scale AHS integration across multiple pits and variable ground conditions.

    Central Nevada Gold’s Mule Canyon acquisition: project and risk lens for engineers

    Central Nevada Gold has completed a US$20 million acquisition of Newmont’s past‑producing Mule Canyon mine in Nevada, targeting a prefeasibility study and key permits in H2 2027 ahead of a potential 2028 construction decision. Mule Canyon previously produced about 500,000 oz gold at an average head grade of 3.8 g/t with ~94% metallurgical recovery, and comes with a database of 2,149 drill holes totalling over 335,000 metres across six mineralised zones over 2.5 km. The company plans an IPO as early as 2027 after a 20‑hole metallurgical and infill drilling programme to upgrade inferred resources and de‑risk the project.

    Greenland Mines’ Sarfartoq licence: key project and offtake notes for mine planners

    Greenland Mines has secured government approval under the Greenland Mineral Activities Act for the indirect transfer of the Sarfartoq carbonatite complex exploration licence, clearing a key condition in its US$35 million acquisition from Neo Performance Materials, which retains offtake rights to up to 60% of future ore or concentrate. The Nd-Pr-enriched project, about 60 km from Kangerlussuaq, carries a historic NI 43-101 resource with 5.88 Mt indicated at 1.77% TREO and 2.46 Mt inferred at 1.59% TREO, based on 23,000 m of drilling. The news sent Greenland Mines’ NASDAQ-listed shares up more than 22%, giving the company a market capitalisation of US$31.4 million.
