• Heavy Rare Earths granted two exploration licenses comprising the Perenjori REE project in WA
  • Perenjori is one of four rare earths projects in company’s portfolio
  • The project has not previously been explored for rare earths
  • Soil and rock chip sampling is planned


Special Report: Heavy Rare Earths has been granted the Perenjori rare earths project by the WA Department of Mines, Industry Regulation and Safety, adding yet another REE project to its portfolio.

The company already holds the Cowalinya and Merino projects in WA, and Duke in the NT.

Notably, Cowalinya is a clay-hosted rare earth project with an inferred resource of 159Mt at 870 ppm TREO and a desirable rare earth composition where 28% are the valuable magnet rare earths and 23% the strategic heavy rare earths.

Cowalinya also features an Exploration Target of 280-1390Mt at 330-1330 ppm TREO.

At the Perenjori project, Heavy Rare Earths (ASX:HRE) is targeting heavy rare earths (HREE) enriched ion-adsorption clay-hosted deposits similar to those found in southern China and Myanmar which supply most of the world’s HREEs.

The Perenjori and nearby Merino area have both ranked very highly in an internal study targeting this style of mineralisation in Western Australia’s palaeochannels.

No historic exploration for rare earths

The Perenjori project is around 185km from Geraldton and covers an area of 329 km2 in two adjacent exploration licences, E70/6397 and E70/6398.

Chemical analysis by the Geological Survey of WA shows that granitic intrusions immediately north of the project contain between 363-889ppm TREE (total rare earths), however no samples were analysed within HRE’s tenements.

Palaeochannels are inferred to occur beneath most of the project area but owing to the complete absence of exploration drilling on HRE’s tenements, the precise location and depth of these palaeochannels remains uncertain.

Both Perenjori and the nearby Merino have received minimal exploration attention and neither area has previously been explored for rare earths.
