    McEwen’s expanded high-grade Froome mine zone: resource and scheduling notes for engineers

    McEwen’s expanded high-grade Froome mine zone: resource and scheduling notes for engineers

    First reported on MINING.com

    30 Second Briefing

    McEwen Mining reports that new drilling at the Froome mine in northern Ontario has increased the high-grade gold zone by about 45%, with hole 25PR-G467 returning 31 metres at 7.7 g/t from 298 metres and 25PR-G478 cutting 15 metres at 6.1 g/t from 328 metres. Mineralisation has been extended 100 metres vertically and up to 50 metres west in the Froome West zone, remains open at depth, and is being tested by four active surface diamond rigs. Continued success could support concurrent mining at Froome and the planned Stock mine from mid-2026, ahead of an updated Froome West resource due in February.

    Technical Brief

    • Hole 25PR-G454 returned 7 metres at 6.4 g/t Au from 169 metres downhole.
    • Deeper hole 25PR-G487 intersected 8.1 metres at 4.6 g/t Au from 358 metres.
    • The Fox complex hosts 18.6 Mt measured and indicated at 3.64 g/t Au (2.18 Moz contained).

    Our Take

    The reported 7–8 g/t gold intercepts at Froome West sit well above the 3.64 g/t measured and indicated grade for the broader Fox complex, which suggests scope to upgrade near-mine feed quality or extend mine life without materially increasing haul distances.

    With McEwen’s market value around C$1.4 billion and Fox holding 2.18 million oz of contained gold, incremental high-grade additions at Froome could be disproportionately value-accretive compared with greenfield ounces, especially given the mid-2026 planning horizon for the complex.

    Among the 54 keyword-matched gold pieces in our database, relatively few involve established Ontario camps like Timmins; McEwen’s results therefore reinforce the narrative that mature Canadian districts can still yield meaningful grade gains through focused underground drilling (four rigs active here).

    CITIC HIC semi-mobile crusher at Duobaoshan: design and throughput notes for mine planners

    A PSZ3000-B semi-mobile gyratory crushing station, independently designed and built by CITIC Heavy Industries in Luoyang, has completed no-load and load commissioning at Zijin Mining’s Phase II expansion of the Duobaoshan copper-molybdenum mine in Heilongjiang, with all performance indicators meeting design standards. The semi-mobile unit is configured as a primary crusher station for the expanded open pit, allowing truck-fed in-pit crushing with conveyor transfer to downstream processing. For mine planners and plant engineers, the successful commissioning confirms Chinese-built large semi-mobile gyratory technology as a viable option for high-throughput greenfield and brownfield expansions.

    LEEA GLAD procurement survey: compliance and lifecycle insights for mine teams

    LEEA has launched a procurement-focused survey to feed into a new white paper scheduled for release on Global Lifting Awareness Day (GLAD) on 2 July 2026, with details hosted on the updated campaign site globalliftingawarenessday.com. Targeted at stakeholders who specify or purchase cranes, hoists, slings and other lifting accessories, the initiative centres on the theme “Not all lifting equipment is…”, aiming to capture how compliance, whole‑life cost and inspection regimes are currently weighted in buying decisions. Mining owners, EPCMs and contractors can use the findings to benchmark procurement practices against industry expectations and tightening safety standards.

    Hitachi EH5000 100,000‑hour milestone at Lumwana: capex and fleet life notes for planners

    Three 296 t class Hitachi EH5000 rigid dump trucks at Barrick’s Lumwana copper mine in Zambia have each passed 100,000 operating hours, an unusually high lifecycle for ultra-class haulage equipment in hard-rock copper operations. The milestone, marked at a joint Barrick–Hitachi recognition ceremony, points to effective component rebuild strategies, condition-based maintenance and strong dealer support for the EH5000 fleet. For mine planners and maintenance teams, it signals potential to extend truck life beyond typical replacement cycles, with implications for capex timing and fleet renewal strategies.
