The thermal material that outperforms copper and aluminium.
Pure Resources Limited (ASX: PR1) is building a sovereign-aligned multi-material platform for AI data centres, advanced electronics and AUKUS defence — anchored by Garnet Hills (WA), the Oak Ridge National Laboratory Strategic Partnership and the Rice University CNTF thermal management IP collaboration.
CNTF vs Copper & Aluminium
On a like-for-like conductivity basis, CNTF is approximately 1.5× copper and ~2.5–3× aluminium.

- Copper~400 W/m·KIndustry reference (~385–400 W/m·K)
- Aluminium~235 W/m·K~205–235 W/m·K

One orebody. Two world-class partners. Three defence-aligned streams.
A vertically integrated strategy linking the source of critical carbon and rare-earth feedstocks to the high-value materials and systems that AI and defence depend on.
Garnet Hills (M80/416)
100%-owned, granted Mining Lease at Reedy Creek (Halls Creek, WA). Premium andradite abrasive garnet on a NAVSEA qualification pathway, large-to-jumbo flake graphite, and HREE+Y potential under the ORNL programme.
Rice University · CNTF
Funded R&D collaboration with Rice University on Carbon Nanotube Fibre — confirmed thermal conductivity ~600 W/m·K, approximately 1.5× copper and 2.5–3× aluminium.
ORNL SPP Agreement
Strategic Partnership Projects Agreement with UT Battelle, LLC operating ORNL under US DoE prime contract — heavy rare earth recovery from Garnet Hills industrial garnet.
Sovereign-aligned. Mission-critical.
Pure Resources is positioned as a sovereign-aligned multi-material supplier into US and AUKUS defence supply chains. Each Garnet Hills stream sits squarely on the United States critical minerals priority list.

Thermal management for AI accelerators, radar power loads, directed-energy weapons and autonomous platforms.
Heavy rare earths critical to F-35, Virginia/Columbia-class submarines, AESA phased-array radar and EW suites.

Five decades of fixed performance from copper and aluminium.
AI accelerator power density has grown roughly 18× since 2010. Conventional metal cooling has not. CNTF emerges as the next-generation thermal conductor.
