Garnet Hills — three streams, one orebody.
The 100%-owned Garnet Hills Project (Reedy Creek tenement package M80/416, E80/3906, E80/4732, E80/3864) is the upstream anchor of Pure Resources' Defence Materials Platform Strategy. A high-grade andradite garnet skarn outcrops over ~3.3 km of strike, hosting large-to-jumbo flake graphite and providing a structurally favourable host for heavy rare earth elements plus yttrium (HREE+Y).
High-grade andradite garnet skarn.
Mapped garnet skarn outcrops over ~3.3 km of strike within a granted mining lease, 90 km north of Halls Creek and adjacent to the Great Northern Highway. Wyndham port is approximately 280 km by road.
One orebody. Three defence-aligned revenue streams.
Each stream is being progressed with direct line of sight to United States and AUKUS-aligned demand, qualification pathways and customer pull.
Defence Abrasive Garnet
Premium andradite garnet for high-specification jet cutting, precision abrasive blasting, and naval shipbuilding and maintenance — including aircraft carrier and submarine hull preparation and surface treatment prior to coating application.
Jumbo Flake Graphite → CNTF
Confirmed large-to-jumbo flake graphite (200–300 µm category) — the precursor class sought for next-generation Carbon Nanotube Fibre. Feedstock focus of the Rice University thermal management IP collaboration.
HREE+Y Recovery
Strategic Partnership Projects Agreement (No. NFE 25 10985) executed with UT Battelle, LLC operating Oak Ridge National Laboratory under US DoE Prime Contract DE AC05 00OR22725, to develop an economical recovery method for Heavy Rare Earth Elements plus Yttrium from Garnet Hills industrial garnet.
Sovereign-aligned multi-material supplier.
Garnet Hills is no longer a single-commodity industrial minerals asset. Each end market — defence-grade abrasives, thermal management for AI hardware and weapons cooling, and heavy rare earths — sits squarely on the United States critical minerals priority list. By aligning the project with US demand-side policy and customer pull, Pure Resources is materially de-risking the development pathway and diversifying away from the conventional dig-and-ship model.

Path to integrated multi-material supply.
- Phase 1ORNL Tasks 1 & 2
Mobilise representative Garnet Hills feedstock to ORNL for characterisation and digestion. Initiate formal US DoD engagement leveraging the ORNL relationship as the technical anchor.
- Phase 2ORNL Tasks 3 & 4
Separation and purification protocols, final reporting. Develop downstream processing capability. Progress Rice University thermal management collaboration. Expand supply and offtake relationships.
- Phase 3Integrated supply
Establish integrated multi-material supply (garnet, graphite and, if validated, HREE+Y) into United States and AUKUS aligned defence, energy and advanced manufacturing markets.
