Victory’s hafnium at North Stanmore: flowsheet and revenue notes for engineers
Reviewed by Tom Sullivan
First reported on Australian Mining
30 Second Briefing
Victory Metals has reported metallurgical test work at its North Stanmore rare earths project near Cue in Western Australia confirming a high-value hafnium by-product alongside its clay-hosted REE mineralisation. The company is advancing flowsheet development to selectively recover hafnium from leach solutions already designed for rare earth extraction, positioning the metal as a potential “game-changer” revenue stream. For process and project engineers, the key issue will be integrating hafnium separation into existing hydrometallurgical circuits without materially increasing reagent consumption or capital intensity.
Technical Brief
- Hafnium reports in the same leach liquor as rare earths from North Stanmore clay-hosted mineralisation.
- Metallurgical work indicates hafnium is selectively recoverable without materially altering existing leach conditions.
- Test work is being completed on bulk composite samples representative of current resource domains.
- Victory is assessing additional solvent extraction stages to split hafnium from zirconium and other high-field-strength elements.
- Integration studies focus on maintaining rare earth recovery while adding a hafnium bleed stream from loaded solutions.
- Project economics are being remodelled to include a hafnium by-product credit alongside rare earth revenue.
- Flowsheet options under review include separate hafnium precipitation versus co-precipitation followed by downstream refining.
- Outcome will influence sizing of hydrometallurgical plant equipment, particularly mixer-settlers and impurity removal circuits.
Our Take
Hafnium appears in only a handful of keyword-matched pieces in our database, signalling that Victory Metals is moving into a niche, high-specification metals space rather than the bulk commodities that dominate Western Australian project coverage.
For a Western Australia project like North Stanmore, positioning around hafnium could open doors to defence, aerospace and advanced electronics supply chains, which typically involve longer qualification cycles but can support premium pricing and offtake stability.
Within our 955 Mining stories, most Australian project items centre on iron ore, gold and battery metals, so a hafnium-focused development may face fewer direct domestic competitors but also a thinner local service and processing ecosystem to draw on.
