    Newcore Gold’s 24% Enchi resource lift: project economics and pit design lens

    Newcore Gold’s 24% Enchi resource lift: project economics and pit design lens

    First reported on MINING.com

    30 Second Briefing

    Newcore Gold has increased the Enchi project’s pit-constrained resource in southwestern Ghana by 24% to 2.13 million oz., including 1.5 million oz. indicated and 626,000 oz. inferred, supported by a 60,000-metre drilling campaign across a 248-sq.-km land package on the Sefwi-Bibiani belt. Resource pits currently average only 85 metres deep, with most drilling to about 125 metres, and all four deposits remain open along strike and at depth, signalling scope for further expansion. A 2024 PEA outlined a nine-year open-pit, heap-leach operation producing ~122,000 oz./year, with initial capex of $106 million, after-tax NPV of $371 million and 58% IRR at $1,850/oz., ahead of a June prefeasibility study.

    Technical Brief

    • Resource growth derives from a 60,000-metre drill campaign focused on both conversion and expansion.
    • Indicated ounces have more than doubled over three years, materially improving input confidence for mine design.
    • All four pit-constrained deposits remain open along strike and down-dip, implying further pit pushback potential.
    • Current resource shells average only 85 m depth, with drilling typically to ~125 m, leaving untested deeper mineralisation.
    • Enchi lies on Ghana’s Sefwi-Bibiani belt, ~50 km south of Asante Gold’s Chirano mine, benefiting from established regional infrastructure.
    • Location is ~300 km from Accra, implying haulage and logistics planning over a relatively long but fully onshore route.

    Our Take

    With an after-tax NPV of $371 million against initial capital of $106 million, Enchi in southwestern Ghana screens as a relatively high-margin, low-capex open-pit gold project in our database, which could make it competitive for funding even against larger African gold developments.

    The shallow average drilling and pit depths at Enchi, combined with a 248 sq.-km land package on the Sefwi-Bibiani belt near Chirano, suggest meaningful upside from deeper and step-out drilling that could extend the current nine-year mine life without materially changing the project’s infrastructure footprint.

    Endurance Gold Reliance step-outs: resource and metallurgy lens for mine planners

    Endurance Gold’s 2026 drilling at the Reliance project in southern British Columbia has returned high-grade step-outs outside the current resource, including 14.7 metres at 7.67 g/t gold and 0.13% antimony from 75.9 metres in DDH26-128 and 12 metres at 3.07 g/t gold from 98.2 metres in DDH26-129, a 60-metre step-out along the Eagle trend. The 8,000-metre diamond programme, with seven holes (1,899 metres) already completed at southern Eagle and two deep tests at Imperial, targets conversion of near-surface ounces and deeper Royal Shear extensions. Reliance currently hosts 19.6 million inferred tonnes at 2.3 g/t gold (1.45 million oz), with metallurgical work aiming to improve recoveries beyond earlier 84.7% gold to concentrate.

    Caterpillar 794 AC at Quellaveco 500 Mt milestone: haul design notes for engineers

    Caterpillar’s autonomous 794 AC haul truck fleet at Anglo American’s Quellaveco copper mine in Moquegua, Peru has passed 500 Mt of material moved, with Ferreyros supporting the deployment as Caterpillar’s local representative. The fully autonomous trucks operate on steep, high-altitude pit ramps typical of Andean copper operations, integrating with digital fleet management and high-precision guidance systems. The milestone signals growing confidence in large-scale autonomous haulage for greenfield copper projects, with implications for haul road design, traffic management rules, and maintenance planning.

    Los Bronces–Andina JV: integrated mine plan implications for planners and geotechs

    Anglo American, via its 50.1%-owned Anglo American Sur SA, and Codelco have finalised a definitive agreement to run a joint mine plan for the adjacent Los Bronces and Andina copper operations in central Chile, after securing all competition and regulatory approvals. The integrated planning covers two large-scale open pits sharing the same Andean district, enabling coordinated sequencing of ore bodies, waste dumps and tailings storage across property boundaries. For mine planners and geotechnical teams, this opens scope for shared slope design, haul road rationalisation and potentially consolidated infrastructure for high-altitude water and power supply.
