    Rincon’s Telfer South expansion: deeper targets and design notes for mine planners

    Rincon’s Telfer South expansion: deeper targets and design notes for mine planners

    First reported on Australian Mining

    30 Second Briefing

    Exploration activity is ramping up across Australia, with Rincon Resources expanding gold–copper targets at its Telfer South project, Hillgrove Resources progressing work at the Kanmantoo copper mine, and Auravelle Metals advancing its battery metals portfolio. Rincon is extending drilling and geophysics south of Newcrest’s Telfer operations, targeting deeper intrusive-related mineralisation, while Hillgrove focuses on resource growth and underground potential at the existing open pit. For geotechs and mine planners, the work signals more near-mine drilling, deeper targets and potential future cutbacks or underground access designs.

    Technical Brief

    • Near-mine exploration intensity around existing pits suggests future requirements for wall stability reviews and cutback optimisation.

    Our Take

    Rincon Resources, Hillgrove Resources and Auravelle Metals appear together in other recent Australian exploration coverage in our database, signalling that all three are in an active capital deployment and drilling phase rather than just holding ground.

    With Australia dominating the 1219 Mining stories in our coverage, incremental target expansion at projects like Telfer South tends to be a precursor to more substantial resource definition campaigns once early contract work de-risks access and logistics.

    Hillgrove Resources’ recent profit uplift from the Kanmantoo underground copper mine suggests it may have more internal cash flow to allocate to Australian exploration work, which could indirectly support or benchmark activity levels around projects such as Rincon’s Telfer South.

    US DOE $10M critical minerals R&D: process insights for mining engineers

    The US Department of Energy has awarded $10 million via the Critical Materials Innovation Hub to seven early-stage R&D projects targeting more efficient recovery and refining of rare earth elements, gallium, copper and other critical materials. Funded work includes chloride-based molten salt electrolysis for heavy rare earth production at Case Western Reserve, hydro and bio-hydrometallurgical copper extraction at Colorado School of Mines, and nanobubble–surfactant–reactive oxygen leaching of copper sulphides at the University of Arizona. FAST Metals, Indium Corporation, Oak Ridge National Laboratory and the University of Illinois will trial solid-phase extraction, advanced ion-exchange resins and redox-adsorbents to recover gallium and mixed rare earth oxides from bauxite-alumina circuits, zinc refinery residues and industrial byproduct streams.

    Maglut Heavy Industries rare earth strategy: ARC-1 process insights for mine planners

    Maglut Heavy Industries is developing a chromatography-based rare earth processing platform at its pilot-scale Long Beach, California facility, reporting 99.9%+ purity for individual rare earth oxides using its ARC-1 water-based separation process. The company designs and manufactures its own resin and ligand systems, aiming for globally competitive costs versus conventional solvent extraction as US defence contractors face January 2027 rules to eliminate Chinese rare earth magnets. A demonstration-scale plant is planned to be fully operational by August 2027, producing commercial rare earth oxides and potentially expanding to other critical minerals.

    Gold price retreats from three‑month high: risk notes for mine planners

    Gold retreated from a three-month high after July US PCE inflation printed at 3.7% headline and 3.3% core, with Comex December futures down 1% to $4,649.10/oz and spot off 1.4% at $4,592.53 by late morning in New York. The pullback follows a 14% August surge in bullion, driven by US Treasury bond-market intervention and a 28-tonne weekly inflow into gold-backed ETFs, ahead of Kevin Warsh’s first Jackson Hole speech as Fed chair. Gold and silver miners still post outsized August gains, with Eldorado up 55%, Equinox 53% and Newmont 41%.
