    Bellevue gold ramp-up: mine design and production lessons for engineers

    Bellevue gold ramp-up: mine design and production lessons for engineers

    First reported on Australian Mining

    30 Second Briefing

    Bellevue Gold has reported record underlying free cash flow for the March 2026 quarter at its Bellevue operation in Western Australia, driven by higher head grades and stronger mill performance as the project moves through ramp-up. The underground mine, targeting more than 200,000oz per annum at nameplate, is increasing stoping tonnage from the Armand and Deacon lodes while continuing development of new high-grade panels. Management is prioritising accelerated decline advance and ventilation upgrades to support higher ore production rates and sustain the improved grade profile.

    Technical Brief

    • Additional high-grade stoping panels are being developed in parallel to existing production areas.
    • Decline advance is being accelerated to open up deeper mining fronts and shorten future haul distances.
    • Ventilation upgrades are planned to increase airflow capacity and support higher diesel equipment utilisation.
    • Mill performance improvements are being driven by better plant availability and tighter operating control, not expansion.
    • Development ore continues to supplement stoping tonnes, maintaining plant feed while new panels are established.

    Our Take

    Bellevue Gold’s move to ramp up its Western Australian operation follows the earlier decision (February 2026) to build a paste backfill plant for the Deacon and Deacon North areas, signalling a shift from early production into a more fully optimised, long-life underground mining configuration.

    The combination of record renewable power penetration flagged in November 2025 coverage and the current ramp-up at the Bellevue Gold operation means this Western Australian mine is likely to feature in ESG-focused gold supply discussions, especially for offtakers seeking lower-carbon ounces from established jurisdictions.

    Integrated Pump Technology in Central Africa: dewatering design notes for mine engineers

    Integrated Pump Technology is expanding dewatering support in Central Africa’s mines as more erratic, climate-driven rainfall increases pit flooding and sump inflows, deploying Grindex submersible units and Godwin diesel-driven surface pumps for both open-pit and underground operations. The company is pairing high-solids, high-head pump selections with local distributor partnerships and on-site application audits to match pump curves to specific shaft depths, static heads and slurry loadings. For mine operators, the focus is on maintaining pumping capacity during peak storm events and reducing unplanned downtime from flooded haul roads, declines and pump chambers.

    Sandvik Rock Processing Reborn in Africa: retrofit economics for mine engineers

    Sandvik Rock Processing’s Reborn programme is gaining uptake at African mines and quarries seeking higher throughput from existing primary and secondary crushers while limiting capex. The scheme replaces ageing crusher cores with new Sandvik units in the original frames and foundations, allowing plants to retain chutes, civils and conveyors while upgrading to current crusher technology and automation. PC Kruger, Business Line Manager Crushing, positions Reborn as a step beyond standard refurbishment, targeting faster installation, reduced downtime and predictable lifecycle costs.

    Cementation Africa in deep underground mining: design and risk insights for engineers

    Africa’s push into deeper, more complex underground orebodies is driving demand for specialist contractors such as Cementation Africa, which combines shaft sinking and raiseboring capability with in‑house engineering and risk management. The contractor is focusing on technically challenging work, including high-stress rock mass conditions, complex ground support regimes and critical‑path access infrastructure for new critical minerals projects. For mine owners, the key shift is from pure construction procurement to integrated delivery models where design, construction methodology and risk allocation are tightly coupled.
