Richard Brescianini, Heavy Rare Earths Limited on Cowalinya project and what drives REE Economics

Richard Brescianini, Executive Director of Heavy Rare Earths Limited (ASX: HRE) updates us on the Cowalinya project in Western Australia

HRE's Cowalinya project in Western Australia is located 100km north east of Esperance and only 40km east of a sealed highway and rail line that links Kalgoorlie with the port at Esperance.

This Cowalinya strategic location was meticulously selected based on promising historical drilling results, showcasing the presence of rare earths anomalies in pristine bedrock. Even more enticingly, higher grade supergene concentrations of rare earths have been discovered in the overlying in-situ weathered saprolite profile.

HRE resource appears to be headed for a substantial upgrade, boasting a higher grade than initially projected. Remember, the REE business is a long-term endeavor, and wise investors should conduct thorough research and adopt a strategic approach for sustained success.

Looking ahead, a potential partnership in non-China-based downstream operations could propel HRE to new heights. Collaborations in the Esperance region present an ideal location, especially for non-China economies seeking to bolster their REE supply and manufacturing capabilities. The Australian government's support for value-adding industries in this area would undoubtedly make perfect sense.

About Cowalinya Project - Western Australia

Cowalinya, a rare earth project in Western Australia, features a 230 km2 exploration license. Targeting supergene concentrations of rare earths over granitic basement, it shows similarity to Chinese ionic clay deposits, a key source of heavy rare earths. Initial drilling has already revealed significant rare earth concentrations in Cowalinya South and North areas. The project's maiden Inferred Mineral Resource estimates 28 Mt @ 625 ppm TREO, with 25% valuable magnet rare earths and 23% strategic heavy rare earths. Metallurgical tests exhibit >90% recoveries for some rare earths using a weak hydrochloric acid leach. Exciting potential lies ahead as the resource remains open in all lateral directions.
