    DevEx drilling strikes uranium at Nabarlek: restart signals for mine planners

    First reported on Australian Mining

    30 Second Briefing

    DevEx Resources has intersected shallow uranium mineralisation at the Nabarlek uranium project in the Northern Territory, with first-pass drilling returning up to 1.7m at 1116ppm uranium equivalent and 2.3m at 920ppm at the Nabarlek North prospect. The intersections come from a 40‑hole, 11,050m reverse circulation and diamond drilling campaign across four priority targets around the historic Nabarlek mine. Results suggest continuity of mineralisation along key structures, signalling follow‑up step‑out drilling and closer‑spaced resource definition work for potential restart studies.

    Technical Brief

    • Mineralisation was intersected at shallow depths, implying relatively short drill hole lengths for key hits.
    • Structural continuity of uranium-bearing zones was observed along mapped faults and shear corridors.
    • First-pass programme layout focused on step-out holes from known historical workings and anomalies.
    • Diamond tails provide core for structural logging, alteration mapping and density / geotechnical measurements.
    • RC pre-collars accelerate penetration through cover sequences before entering prospective basement lithologies.
    • Results set up tighter-spaced follow-up drilling needed for JORC-compliant resource definition and restart studies.

    Our Take

    DevEx Resources’ recent leadership change and A$7.5 million move on Alligator Energy, noted in our uranium coverage, suggests the Nabarlek uranium project drilling in the Northern Territory is part of a broader push to scale a multi-asset uranium portfolio rather than a single-asset play.

    Within our 42 uranium-tagged pieces, most Australian stories centre on regulatory and market dynamics rather than early-stage drill intervals, so these 1.7–2.3 m mineralised hits at Nabarlek North position DevEx among the more technically advanced junior explorers in the domestic uranium space.

    The 40-hole, four-target drilling program at Nabarlek North indicates a relatively tight, hypothesis-driven campaign; in our database, similar-scale uranium programs in Australia often precede either a focused resource-definition phase or strategic farm-in discussions if follow-up results hold up.

    Finsch Diamond Mine mobile fleet sale: asset value and fit for hard-rock operators

    Large-scale underground and surface equipment from Finsch Diamond Mine (Pty) Ltd near Lime Acres in South Africa’s Northern Cape is being sold through a structured asset disposal process run by Park Village Auctions as part of business rescue proceedings. The package includes a substantial mobile mining fleet, processing plant components and supporting infrastructure, with the process explicitly geared to maximising realisable value. For operators in hard-rock underground mining, the sale offers a rare opportunity to acquire compatible diamond-mine-grade assets without greenfield lead times.

    BME’s smarter explosive supply for African mining: logistics and safety notes for engineers

    BME, part of Omnia Holdings, is rolling out modular, containerised emulsion plants to give remote African mines secure on-site explosive manufacture instead of relying on long-haul bulk deliveries. Production and Logistics General Manager Dirk Voogt says the units are designed for regions such as West Africa where poor road infrastructure, border delays and port congestion frequently disrupt ammonium nitrate and emulsion supply. The plug-and-play plants allow mines to stabilise blasting schedules and stock levels, with process control and security integrated into the container footprint.

    ABB power conversion at Fortescue’s North Star: grid‑stability lessons for mine power

    Fortescue is installing an ABB power conversion system at its North Star Junction hub in the Pilbara to stabilise its emerging high‑voltage power network for large‑scale iron ore operations. The PCS will manage bidirectional power flows between grid, renewables and storage, providing fast frequency and voltage support to maintain quality supply for heavy mining loads and long overland conveyors. For engineers, the project signals growing demand for grid‑scale PCS integration in remote mines transitioning away from diesel generation.
