Tanami Project and tenement location
- The project area sits in the Western Tanami Desert within the Birrindudu basin of North Australia, within Western Australia.
- The project is 30km from known hydrothermal unconformity-related rare earth element (HURREE) deposit, Northern Minerals (ASX:NTU) Browns Range mine (10.81 Mt @ 0.76% Total Rare Earth Oxide (TREO) with 81,450 tonnes of contained TREO).
- The project is also 4km from Black Cat Syndicates (ASX:BC8) Coyote Operations (3.7mt @ 5.5 g/t Au for 645,000 oz).
- Significant Au and REE mineralisation have been determined within PVW Resources’ Tanami Project.
- REE anomalism is distinguished by high HREO/TREO (60–93% within the Pargee Sandstone) due to the presence of xenotime mineralisation, related to a Hydrothermal Unconformity-Related Rare Earth Element (HURREE) system.

Key ingredients for discovery success
An unconformity-related HREE deposit must have:
The right stratigraphic setting
- Unconformity between the Pargee Sandstone and the Killi Killi Formation on the Watts Rise-Castella trend is analogous to the unconformity between Gardiner Sandstone and Browns Range Metamorphics at Browns Range.
The right style of mineralisation
- Extensive surface mineralisation includes HREE in Xenotime, confirming the right ore-forming system (the same mineral host as Browns Range).
The right plumbing system
- Significant structures (faults and folds) are present offsetting and deforming the unconformity, providing fluid flow for the hydrothermal system.
- The Pargee Sandstone and the Killi Killi Formation both host mineralisation with breccia zones, potentially providing an analogous setting to the Browns Range Wolverine deposit.
