    Brightstar’s new Sandstone gold targets: corridor focus and design notes for planners

    Brightstar’s new Sandstone gold targets: corridor focus and design notes for planners

    First reported on Australian Mining

    30 Second Briefing

    Brightstar Resources has defined 11 priority gold targets along the Two Mile Hill–Bull Oak corridor within its 3.6-million-ounce Sandstone project in Western Australia, with drilling scheduled to start in November. The targets were generated by integrating geological mapping with geophysical datasets to pinpoint mineralisation analogous to the existing Two Mile Hill system. For geologists and mine planners, the work concentrates exploration along a specific structural corridor, potentially extending known ore shoots and influencing future resource modelling and mine design at Sandstone.

    Technical Brief

    • Corridor work focuses on the Two Mile Hill–Bull Oak structural trend within the Sandstone tenure.
    • Targeting is explicitly analogue-based, seeking repetitions of the known Two Mile Hill intrusive-hosted system.
    • Geological mapping has been integrated with multiple geophysical datasets rather than relying on drilling alone.
    • Similar analogue-driven targeting along defined structural corridors is now common on mature Archaean goldfields in WA.

    Our Take

    The 3.6Moz resource at Brightstar’s Sandstone gold project now sits alongside the recently reported 1.45Moz at Two Mile Hill–Shillington, signalling that Western Australian ounces are consolidating across multiple deposits rather than a single flagship pit.

    Our database shows several recent Brightstar items focused on deep drilling at Two Mile Hill–Shillington and thick mineralised intercepts at Bull Oak, so the 11 new priority targets along the Two Mile Hill–Bull Oak corridor likely aim to stitch these discoveries into a continuous, multi-decade mining corridor.

    With Brightstar also advancing the Laverton Goldfields development towards first gold in 2027, incremental discoveries at Sandstone in Western Australia could materially influence how the company sequences feed between Sandstone and the new Laverton processing hub.

    TAKRAF–FSI FILTRACIÓN deal: filtration design and tailings takeaways for engineers

    TAKRAF Group has acquired Madrid-based FSI FILTRACIÓN SL, an engineering company specialising in liquid/solid separation and filtration technologies, with the transaction closing on 3 November 2026. FSI FILTRACIÓN will be integrated into TAKRAF’s DELKOR filtration portfolio but continue serving its existing customer base, adding proprietary filter designs and process know-how for mining and industrial slurries. The deal signals further consolidation in high-capacity filtration, relevant for tailings dewatering, concentrate filtration and water recovery in new and brownfield plants.

    Cat D11 XE electric drive dozer: efficiency and control insights for mine engineers

    Caterpillar has launched the Cat D11 XE, a 100‑plus‑tonne high‑drive electric drive dozer that scales its D6 XE and D8 XE electric architecture up to flagship mining and bulk earthmoving duties. The D11 XE replaces torque converters, multi‑speed transmissions and drop boxes with a generator–motor powertrain, keeping the diesel engine in its optimal speed band to cut fuel use per tonne moved and reduce mechanical complexity. Continuous electric torque to the tracks reduces gear‑shift interruptions, track slip and undercarriage wear while improving fine blade control in variable ground conditions.

    Fluor EPCM for Sierra Gorda grinding line: integration and civil works lens

    Fluor Corporation has received full notice to proceed as EPCM contractor for the Fourth Grinding Line Expansion Project at Sierra Gorda Sociedad Contractual Minera’s large open-pit copper-molybdenum operation, 60 km south of Calama in Chile’s Antofagasta Region. The brownfield project adds a new grinding line to the existing concentrator, requiring integration with operating crushing, conveying and process water systems. For geotechnical and civil teams, key tasks will centre on foundations, earthworks and tie-ins around an active plant with constrained layouts and ongoing production.
