Victory Metals’ dual revenue HREE flowsheet at North Stanmore: design notes for engineers
Reviewed by Tom Sullivan

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.
