    Tivan mobilises for Molyhil tungsten drilling: design and data notes for engineers

    First reported on Australian Mining

    30 Second Briefing

    Tivan has begun mobilisation for its 2026 fieldwork campaign in central Australia, preparing a drilling program at the Molyhil tungsten project to advance resource definition and project feasibility. The work follows earlier studies on Tivan’s Speewah vanadium–titanium–iron project in Western Australia, signalling a renewed focus on critical minerals assets across multiple jurisdictions. Geotechnical and drilling contractors should expect demand for tungsten-focused core drilling, structural logging and updated geometallurgical data to refine mine design and processing flowsheets ahead of potential development decisions.

    Technical Brief

    • Mobilisation phase likely includes establishing drill pads, access tracks and temporary core handling facilities.
    • Central Australian setting implies arid conditions, so water supply and drilling fluid logistics will be a key constraint.
    • Tungsten mineralisation at Molyhil will require oriented diamond core for structural logging and vein geometry definition.
    • Core-derived geotechnical parameters will feed pit slope design, haul ramp geometry and waste dump stability assessments.
    • Detailed geometallurgical sampling from new holes will refine grind size, liberation and gravity/flotation circuit design.
    • Similar tungsten projects increasingly front-load structural and geometallurgical drilling to de-risk feasibility-stage mine design.

    Our Take

    Our database shows Tivan’s 2026 fieldwork at the Molyhil tungsten project follows its January 2026 acquisition of the asset, signalling a relatively rapid move from transaction to on-ground drilling compared with many Australian critical minerals deals.

    Linking Molyhil in central Australia with the planned central Australian critical minerals hub referenced in the January 2026 piece likely allows Tivan to leverage shared infrastructure and processing for both tungsten and its fluorite assets such as Speewah.

    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.
