    Greatland’s March 2026 Havieron quarter: design and planning notes for mine teams

    Greatland’s March 2026 Havieron quarter: design and planning notes for mine teams

    First reported on Australian Mining

    30 Second Briefing

    Greatland Resources posted a strong March 2026 quarter from its 30 per cent stake in the Havieron gold–copper project in Western Australia’s Paterson Province, partnered with Newmont on a decline-access underground mine. Development has focused on the South East Crescent and Breccia zones, with continued infill and step-out drilling to refine the high-grade mineralisation envelope and support an updated resource and mine plan. For geotechs and mine planners, the results point to sustained underground development, ventilation and paste backfill requirements in competent but variably fractured Proterozoic host rocks.

    Technical Brief

    • For similar Proterozoic underground mining projects, the case reinforces early integration of paste, drilling and decline schedules.

    Our Take

    Greatland Resources’ recent feasibility study work at the Havieron gold–copper project in Western Australia’s Paterson Province suggests that any strong March 2026 quarter likely reflects a transition from pure study phase towards early execution and mine integration planning with nearby operations.

    The addition of a Cat 6060 hydraulic mining shovel to the Telfer gold–copper mine fleet earlier in 2026 indicates Greatland is already committing capital to higher-productivity loading equipment, which typically precedes or accompanies throughput increases and mine-life extension strategies.

    Within our 1216 Mining stories, Western Australia gold–copper items linked to Greatland Resources often centre on long-life underground bulk stoping concepts, so a ‘shining’ quarter here likely signals that the company is consolidating a multi-asset position in the Paterson Province rather than relying on a single flagship project outcome.

    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.
