    Tivan nears 37km drilling at Speewah: resource and pit design notes for engineers

    Tivan nears 37km drilling at Speewah: resource and pit design notes for engineers

    First reported on Australian Mining

    30 Second Briefing

    Tivan is close to completing a roughly 37,000‑metre drilling campaign at its Speewah fluorite project in Western Australia’s Kimberley, including 12,809 metres drilled in the 2026 programme with about 1275 metres remaining. The work is aimed at delivering an updated JORC mineral resource estimate and the project’s first ore reserve ahead of a final investment decision. For geotechnical and mine planning teams, the expanded drill density should tighten grade continuity models and support more detailed pit designs and geotechnical domains.

    Technical Brief

    • Fluorite (fluorspar) focus suggests potential downstream use in acid-grade and metallurgical-grade products.
    • Kimberley climatic conditions mean drilling and future open-pit operations must accommodate intense wet-season rainfall.
    • Remote WA setting points to likely reliance on long-haul road transport for reagents and concentrate.
    • Project scale and remoteness indicate early need to assess on-site power mix (diesel, gas, renewables).
    • Fluorite’s role in steelmaking and chemicals links project economics to steel and HF market volatility.
    • Similar fluorite projects often require careful pit-wall control due to veining and variable rock mass quality.
    • For comparable mining projects, such early drilling density typically de-risks slope design and haul-road geometry.

    Our Take

    Speewah in Western Australia and Sandover in the Northern Territory now give Tivan two advanced fluorite fronts in our database, which suggests the company is positioning itself as a multi-asset CaF₂ supplier rather than relying on a single flagship deposit.

    The earlier appointment of ICA Natural Resources as debt finance adviser for the Speewah fluorite project indicates that near-complete drilling here is likely feeding directly into bankable studies and financing models, rather than just early-stage exploration.

    With only a handful of fluorite‑keyword pieces in our coverage compared with 1276 Mining stories overall, Tivan’s repeated appearances across fluorite, tungsten and critical minerals items signal it as one of the more active Australian juniors in niche industrial minerals and specialty metals.

    Allied Gold’s Kurmuk mine grid tie-in: commissioning lessons for project engineers

    Allied Gold Corporation has connected its Kurmuk gold mine in Ethiopia to the national power grid and run first ore through the primary crushing circuit, key steps in final commissioning. Grid connection removes reliance on temporary diesel generation and enables full energisation of processing, dewatering and mine services infrastructure. Kurmuk is expected to become one of Allied Gold’s premier assets, with ramp-up now focused on stabilising the crushing–grinding line, validating ore throughput assumptions and finalising operating procedures ahead of commercial production.

    Redpath Africa underground expansion: integrated shaft-to-ore services for mine teams

    Redpath Africa Limited is broadening its underground mining proposition beyond its core raiseboring specialism, adding full-scope development, construction and contract mining services across sub-Saharan operations. The company is integrating shaft sinking, lateral development and underground infrastructure installation with its established raiseboring fleet, enabling single-contractor delivery of hoisting shafts, ventilation raises and ore passes. For mine owners, this consolidated offering reduces interface risk on deep-level projects and allows tighter coordination of ground support, excavation sequencing and services installation in complex geologies.
