    Terrain Minerals’ Lightning gold system: drilling takeaways for project teams

    Terrain Minerals’ Lightning gold system: drilling takeaways for project teams

    First reported on Australian Mining

    30 Second Briefing

    Terrain Minerals has reported strong reverse circulation drilling results at its Lightning gold prospect in Western Australia, indicating the mineralised system extends beyond the previously defined footprint. The company is testing multiple stacked lodes along strike and at depth, with recent holes intersecting continuous sulphide-bearing quartz veining and visible gold in several zones. Results will guide follow-up step-out drilling to refine the geometry of the high-grade shoots and support an initial resource model for the broader Bundarra project area.

    Technical Brief

    • For similar Archaean prospects, such stacked lode geometries often favour underground extraction once depth continuity is confirmed.

    Our Take

    Gold projects in Western Australia feature heavily in our 1203 Mining stories, signalling that Terrain Minerals’ Lightning prospect is competing for capital and contractor attention in a very crowded regional exploration pipeline.

    With Australian Mining also covering issues like long lead times for crusher and drill components (see MASPRO piece, 24 March 2026), any move from drilling success at Lightning towards development will likely hinge on how Terrain manages equipment procurement risk.

    Recent coverage of battery-electric fleets and haul-road sensing in Australian mines (e.g. XCMG and Kal Tire/Decoda items from March 2026) suggests that, if Lightning advances to an open-pit operation, there will be strong pressure to factor low-emission and data-rich mobile equipment into early mine planning in Western Australia.

    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.
