    Bellevue’s Deacon North first ore: mine plan and geotechnical notes for engineers

    Bellevue’s Deacon North first ore: mine plan and geotechnical notes for engineers

    First reported on Australian Mining

    30 Second Briefing

    Bellevue Gold has delivered first ore from the high-grade Deacon North zone at its Bellevue underground gold mine in Western Australia, marking a key step in ramping up the new operation. The Deacon North orebody, part of the broader Bellevue system north of Kalgoorlie, is being accessed via underground development targeting narrow, high-grade lodes typical of the district. Early stoping performance and grade reconciliation from this area will be critical for confirming the mine plan, production schedule and geotechnical assumptions for subsequent development fronts.

    Technical Brief

    • Underground haulage and materials handling now need to integrate Deacon North ore into the central processing stream.
    • Geotechnical domains at Deacon North are expected to be structurally controlled, consistent with Bellevue-style lode geometries.
    • Early ground response in Deacon North headings will influence support patterns for subsequent mining panels.
    • Lessons from Deacon North performance are likely to inform sequencing of other high-grade satellite lodes at Bellevue.

    Our Take

    Deacon North’s first ore follows Bellevue Gold’s decision earlier in 2026 to build a paste backfill plant for the Deacon/Deacon North areas, signalling a long-life, high-recovery underground mining strategy rather than short-cycle stoping.

    Our database shows multiple recent items on Bellevue Gold’s strong cash flow and rising grades at its Western Australian operation, so ore from Deacon North is likely being integrated into an already optimised mill and cash-generative asset base.

    2026 Australian Mining Prospect Awards: networking and project angles for engineers

    Tickets are now on sale for the 2026 Australian Mining Prospect Awards gala dinner, to be held on 16 September 2026 at Fraser’s Kings Park in Perth. The event will bring together mining professionals, contractors, OEMs and executives from across Australia to recognise finalists across multiple operational, innovation and ESG-focused award categories. Attendance offers operators, engineers and suppliers a concentrated networking opportunity with project decision-makers ahead of 2027 investment and tender cycles.

    FireFly’s Green Bay project economics: NPV, IRR and capex lens for mine planners

    FireFly Metals’ Green Bay copper-gold project in Newfoundland now carries an after-tax NPV of A$2.2 billion (C$2.1 billion) at a 7% discount rate and a 42% IRR, with initial capital of A$513 million, giving more than four times NPV-to-capex leverage and planned throughput of 1.8 million tonnes per year over 32 years. Updated measured and indicated resources stand at 60.2 million tonnes grading 1.9% Cu, 0.5 g/t Au and 4.2 g/t Ag, containing 1.1 million tonnes Cu, 908,000 oz Au and 8.1 million oz Ag after 69,539 metres of underground drilling. A feasibility study is targeted for Q1 2027, with a final investment decision in H2 2027 and first concentrate potentially in mid-2029, backed by a proposed A$180 million equity raise split between an ASX institutional placement and a Canadian bought deal.

    Waratah’s new shallow high-grade Consols gold zone: pit design notes for planners

    Waratah Minerals has extended the Consols gold system at its Spur project in New South Wales by 75m to the east and down-plunge, while identifying a new shallow high-grade zone. Step-out hole SPD074 intersected 12.7m at 1.35g/t gold from 44m downhole, defining a near-surface target with open extensions. For mine planners and geotechnical teams, the shallow geometry and incremental strike extension suggest potential for low-strip open-pit designs and simplified access for infill drilling and geotechnical characterisation.
