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
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.”

Heavy Rare Earths
Overview
Demand for rare earth elements (REEs) is rapidly increasing. These minerals are necessary to manufacture permanent magnets, auto and fluid cracking catalysts, and are also used in emerging technologies. Much of the world’s REE comes from China, making countries investing in clean energy largely reliant on Chinese supply. However, Australia is quickly ramping up production and was the fourth-largest REE miner in 2021, providing the market with 22,000 tonnes. The country also has the fifth largest reserves globally, with 4 million tonnes.
Heavy Rare Earths Limited (ASX:HRE) is committed to supporting the transition to sustainable technologies by providing new sources of these critical minerals. HRE has 100 percent ownership of two REE projects in Australia. The flagship Cowalinya Project is located in the premier mining jurisdiction of Western Australia and has demonstrated potential for a significant rare earth resource with an ideal composition. The company raised AU$6 million in its IPO, indicating foundation investor confidence and funding campaigns to advance its assets.The Cowalinya Project has a JORC-compliant inferred mineral resource of 28 million tonnes at 625 parts per million (ppm) total rare earth oxides (TREO). The resource has an ideal composition of 25 percent magnet REEs and 23 percent heavy REEs, and importantly also contains low concentrations of radioelements.
The company has also confirmed a substantial new body of rare earth mineralisation at Cowalinya. Assays from 215 holes from HRE’s 441-hole rare earth exploration and resource expansion drilling program in 2022 have revealed multiple high-grade REE intercepts (up to 7222 ppm TREO) and the project’s thickest mineralised intercept to date at 42 meters @ 790 ppm TREO from 12 meters in hole AC226 – within a substantial new Western Zone of rare earth mineralisation.
Heavy Rare Earths’ second project, Duke, is located in the Northern Territory and close to both road and rail. The Company plans to commence exploring the asset for heavy REE-enriched deposits similar to the Browns Range project in Western Australia in the middle of 2023.
A management team with extensive experience in the natural resources sector leads the company, with expertise in rare earth exploration and development, financial management and corporate administration. HRE’s leadership team creates confidence in its ability to bring new REEs to market to support the energy transition.
Company Highlights
- Heavy Rare Earths is an Australian exploration and development mining company focusing on rare earth assets to support the clean energy transition.
- The company has 100 percent mineral rights ownership of two assets in premier mining jurisdictions, Western Australia and the Northern Territory.
- The flagship Cowalinya Project has a JORC-compliant inferred resource of 28 million tonnes at 625 ppm TREO with the highly sought-after composition of 25 percent magnet rare earths and 23 percent heavy rare earths.
- Heavy Rare Earths has confirmed a substantial new body of rare earth mineralisation at Cowalinya in 2023.
- An experienced management team leads Heavy Rare Earths with a range of expertise throughout the mining sector, including project management, corporate administration, and rare earth exploration and development.
Key Projects
The Cowalinya Project
The clay-hosted Cowalinya Project’s three tenements cover 250 square kilometers in Western Australia and is located 110 kilometers from the Port of Esperance. The project's clay-hosted mineralisation is shallow, flat-lying supergene concentrations of REEs similar to the world’s primary source of heavy rare earths in southern China. Drilling is ongoing to define the extent of rare earth resources in the company’s tenements.
Metallurgical test work on these deposits delivered encouraging results, indicating high proportions of sought-after REEs can be isolated and recovered.
Project Highlights:
- Strong Mineral Resource Estimate: The 2021 drilling program was followed by an independent estimate of mineral resources that outlined 28 million tonnes at 625 ppm TREO in inferred resources. The estimate demonstrates a composition of 25 percent magnet rare earths and 23 percent heavy rare earths.*
- Thickest mineralised intercept at Cowalinya to date – The 2022 drill program reported assays from 215 air core holes with the thickest mineralised intercept of 42 meters @ 790 ppm TREO from 12 meters in hole AC226 – within a substantial new Western Zone of rare earth mineralisation.
