Five-Fold Increase in Mineral Resources to 159 Mt @ 870 Ppm Total Rare Earth Oxides at Cowalinya Project in Western Australia

Heavy Rare Earths Limited (“HRE” or “the Company”) is pleased to report a very substantial growth in Mineral Resources at its 100 per cent-owned Cowalinya rare earth project in the Norseman-Esperance region of Western Australia.


Highlights
  • JORC (2012 Edition) Inferred Mineral Resources for the Cowalinya rare earth project now estimated to be 159 million tonnes @ 870 ppm TREO at a cut-off grade of 400 ppm TREO-CeO2
  • This result represents an increase of:
    • 468% in resource tonnes
    • 39% in grade
    • 690% in contained rare earths

on the project’s maiden 2022 Mineral Resources of 28 million tonnes @ 625 ppm TREO at the lower cut-off grade of 300 ppm TREO-CeO2

  • Total contained rare earths of 138,290 tonnes (on a TREO basis)
  • Significantly, the valuable magnet rare earth component of Cowalinya has increased from 25% to 28%
  • Resource upgrade achieved by grid drilling 14,438 metres in 509 holes on 19% of HRE’s total land position
  • Resource excludes multiple rare earths-rich drill intercepts up to 14 kilometres from the resource
  • Maiden Exploration Target for Cowalinya in advanced preparation
  • Downstream metallurgical flowsheet development in progress to produce Mixed Rare Earth Carbonate (MREC) product samples for customer engagement


Cowalinya Mineral Resource Estimate


TREO = La2O3+CeO2+Pr6O11+Nd2O3+Sm2O3+Eu2O3+Gd2O3+Tb4O7+Dy2O3+Ho2O3+Er2O3+Tm2O3+Yb2O3+Lu2O3+Y2O3

Magnet REOs = Pr6O11+Nd2O3+Tb4O7+Dy2O3

Reported above a cut-off grade of 400 ppm TREO-CeO2


HRE Executive Director Richard Brescianini said, ”Today, we have delivered the first key milestone for our Cowalinya rare earth project just 13 months since Heavy Rare Earths listed on the ASX.

“Mineral Resources for Cowalinya now stand at 159 million tonnes, and pleasingly we have seen a 39% grade increase to 870 parts per million of rare earth oxides. This has been achieved on just 19% of our total land position. We have also intersected thick rare earth- rich horizons in drilling up to 14 kilometres from our resource zone1 and very much look forward to presenting the project’s maiden Exploration Target in the near future.

“I also note a material increase in the valuable magnet rare earth component of the resource to 28%. This is best in class amongst clay-hosted resources in Australia.

“Today’s exceptional result sets a solid foundation in demonstrating the potential for a long- life rare earth development project at Cowalinya.”

Rare Earths Stocks: 9 Biggest Companies in 2024

Rare earth elements (REEs) are crucial for technologies like smartphone cameras and defense systems.

A select few from the group of 17 are also vital to the expanding electric vehicle industry — neodymium and praseodymium are used in permanent magnet synchronous motors used in EV drive trains.

China's dominance in rare earth production and reserves has prompted countries like the US, Canada and Australia to boost their own mining and processing efforts to secure their supply chains. The pressure on these nations to establish strong supply chains is likely to grow when a US tariff on imports of Chinese rare earth magnets begins in 2026.

DY6 Metals CEO Lloyd Kaiser Touts Africa's Rising Role in Global Rare Earths Supply Chains

The geopolitical landscape is shifting, and African nations, particularly resource-rich countries like Malawi, are becoming vital to the global supply chain of rare earth metals, according to Lloyd Kaiser, CEO of Australia-based DY6 Metals (ASX:DY6).

Countries such as the US are aiming to diversify their sources of critical minerals and reduce their reliance on China by enhancing relations with African countries.

“Africa offers a lot — it's rich in critical materials and could also help secure supply," Kaiser said, commenting on calls for the US government to build stronger trade relationships with African nations to align with America’s broader objective to ensure a stable and secure supply of essential raw materials.
