    Victory Metals’ North Stanmore pilot: 60x TREO upgrade and flowsheet lessons for engineers

    Victory Metals’ North Stanmore pilot: 60x TREO upgrade and flowsheet lessons for engineers

    First reported on Australian Mining

    30 Second Briefing

    Victory Metals has achieved a near-60-fold upgrade in rare earth concentration at its Perth continuous pilot plant for the North Stanmore project in Western Australia, upgrading feed grading 1195ppm total rare earth oxides (TREO) to a high‑grade concentrate. The pilot‑scale campaign validates the flowsheet at continuous operation rather than batch scale, a key step before full‑scale plant design and capital estimates. For process and project engineers, the result materially improves the potential economics of North Stanmore’s clay‑hosted rare earths by sharply reducing downstream mass pull.

    Technical Brief

    • Continuous pilot-scale testing was conducted at Victory Metals’ Perth facility rather than on-site at North Stanmore.
    • Feed material for the campaign came directly from the North Stanmore clay-hosted rare earths deposit in WA.

    Our Take

    The near-60-fold concentration upgrade at the North Stanmore pilot plant follows Victory Metals’ earlier metallurgical breakthrough reported on 29 April 2026, signalling that the flowsheet for these clay-hosted rare earths is maturing unusually quickly compared with most early-stage REE projects in our database.

    With North Stanmore already accepted into the US Defense Industrial Base Consortium, demonstrable high upgrade factors for total rare earth oxides materially strengthen Victory Metals’ case for future offtake or strategic support linked to defence supply chains, especially for heavy rare earths.

    Recent coverage shows multiple North Stanmore milestones in rapid succession (Native Title Mining Agreement, PFS progress, DIBC acceptance and now pilot-plant performance), which suggests Victory Metals is deliberately de-risking both permitting and processing in parallel to compress the project’s development timeline in Western Australia.

    PLS Pilgangoora 22-sorter TOMRA contract: process design notes for engineers

    TOMRA Mining has secured a contract from Pilgangoora Operations Pty Ltd, a PLS Group subsidiary, to supply 22 sensor-based ore sorters for the P2000 Expansion Project at the Pilgangoora lithium operation in Western Australia. The installation is part of PLS’ pre-Final Investment Decision early works, signalling commitment to large-scale sorting ahead of full project sanction. For process engineers, the move points to increased reliance on front-end sensor-based separation to upgrade run-of-mine feed and manage lithia grade variability before downstream concentration.

    Macmahon’s 42‑month Telfer Gold Mine extension: planning notes for project teams

    Macmahon Contractors has secured a 42‑month extension to provide contract mining services at Greatland Resources’ Telfer Gold Mine in Western Australia, valued at A$485 million over the term. The deal locks in a multi‑year mining services pipeline at one of the state’s major gold operations, supporting continuity of fleet deployment, workforce planning and site-based maintenance. Contractors and suppliers can expect sustained demand for open-pit and underground support services, consumables and rebuilds tied to Telfer’s existing mine plan.

    Metso–Valmet Flowrox pump deal: slurry circuit implications for mine engineers

    Metso has agreed to acquire Valmet’s Flowrox™ peristaltic hose pump and progressive cavity pump technologies, including associated spare parts and service capabilities, targeting abrasive and chemically aggressive slurry duties in mining and minerals processing. The deal adds positive displacement options alongside Metso’s existing slurry and submersible pump lines, enabling tighter process control in applications such as thickener underflow, filter feed and reagent dosing. For operators, the integration should simplify lifecycle support and parts standardisation across critical slurry handling circuits.
