    Victory Metals’ dual revenue HREE flowsheet at North Stanmore: design notes for engineers

    First reported on Australian Mining

    30 Second Briefing

    Victory Metals has reported a metallurgical breakthrough at its North Stanmore project in Western Australia, achieving a globally significant heavy rare earth element (HREE) result from clay-hosted mineralisation. Testwork indicates the ore can support dual revenue streams, with both HREEs and additional payable products recoverable from the same feed, improving project economics compared with single-commodity ionic clay deposits. The development positions North Stanmore for flowsheet design focused on selective leaching and impurity control, critical for scaling commercial rare earth production in WA’s Mid West.

    Technical Brief

    • Metallurgical testwork at North Stanmore used clay-hosted mineralisation from near-surface drill intercepts.
    • Bench-scale leach trials were conducted on composited samples rather than isolated high-grade intervals.
    • Test programme focused on identifying impurity deportment to optimise downstream purification stages.
    • Selective leaching conditions were tuned to minimise dissolution of gangue elements from the clay matrix.
    • Results support a flowsheet concept where multiple payable products are recovered from a single leach circuit.
    • Victory Metals plans further variability testwork across different clay domains to confirm flowsheet robustness.
    • Data from the current programme will feed into preliminary plant design and capital cost estimation.

    Our Take

    Recent coverage of North Stanmore highlights heavy rare earths, yttrium and hafnium test work, so a ‘dual revenue stream’ at this Western Australian project likely refers to monetising both primary REE output and a high-value by-product such as hafnium.

    Within our mining-projects coverage for Western Australia, North Stanmore stands out as one of the few clay-hosted heavy rare earth systems being advanced with a dedicated rare earths leadership team, signalling Victory Metals’ intent to move quickly from test work to development decisions.

    Schlam installation kit programme: interface control and uptime gains for mines

    Schlam has launched a new in-house engineered installation kit programme for mining truck bodies and excavator buckets, giving sites a standardised, end-to-end package covering attachment supply and fit-out. Developed under a three-year product development effort, the kits are designed to integrate with Schlam’s load and haul attachments, reducing the need for bespoke on-site fabrication and ad hoc hardware selection. For maintenance and asset teams, this points to more predictable installation times, simplified spares management and tighter control of attachment interface geometry.

    Integra’s 74% reserve lift at Florida Canyon: project economics for mine planners

    Integra Resources’ updated feasibility study for the Florida Canyon heap leach mine in Nevada lifts proven and probable reserves 74% to 1.1 million oz at 0.31 g/t, raises planned output to 82,000 oz gold per year over eight years, and boosts the 5% NPV to US$601 million using a US$4,200/oz price. All-in sustaining costs climb 43% to US$2,331/oz with recovery steady at 62%, but post-tax free cash flow is projected at US$800 million, averaging US$90 million annually. Integra is drilling 42,500 metres around the existing operation to grow resources and fund its DeLamar gold-silver project in Idaho.

    DRC critical minerals strategy: price-setting and supply risks for mine planners

    Democratic Republic of Congo has shifted from price-taker to price-setter in cobalt by imposing ARECOMS-managed export quotas and planning state stockpiles of cobalt, coltan and germanium. Cobalt prices have climbed from about $21,000/t in early 2025 to just over $56,000/t, with Kinshasa forecasting $2.3 billion in fiscal revenues this year versus an estimated $617 million without intervention. Advisory input from Vectus Global and new investment moves such as Virtus Minerals’ acquisition of Chemaf signal tighter supply discipline and a push for higher value-added partnerships.
