    Greatland’s March 2026 Havieron quarter: design and planning notes for mine teams

    First reported on Australian Mining

    30 Second Briefing

    Greatland Resources posted a strong March 2026 quarter from its 30 per cent stake in the Havieron gold–copper project in Western Australia’s Paterson Province, partnered with Newmont on a decline-access underground mine. Development has focused on the South East Crescent and Breccia zones, with continued infill and step-out drilling to refine the high-grade mineralisation envelope and support an updated resource and mine plan. For geotechs and mine planners, the results point to sustained underground development, ventilation and paste backfill requirements in competent but variably fractured Proterozoic host rocks.

    Technical Brief

    • For similar Proterozoic underground mining projects, the case reinforces early integration of paste, drilling and decline schedules.

    Our Take

    Greatland Resources’ recent feasibility study work at the Havieron gold–copper project in Western Australia’s Paterson Province suggests that any strong March 2026 quarter likely reflects a transition from pure study phase towards early execution and mine integration planning with nearby operations.

    The addition of a Cat 6060 hydraulic mining shovel to the Telfer gold–copper mine fleet earlier in 2026 indicates Greatland is already committing capital to higher-productivity loading equipment, which typically precedes or accompanies throughput increases and mine-life extension strategies.

    Within our 1216 Mining stories, Western Australia gold–copper items linked to Greatland Resources often centre on long-life underground bulk stoping concepts, so a ‘shining’ quarter here likely signals that the company is consolidating a multi-asset position in the Paterson Province rather than relying on a single flagship project outcome.

    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%.
