A hefty increase to its Tampu high purity alumina (HPA) project in WA’s Wheatbelt places Corella as a major force in the critical mineral HPA markets.

The team over at Corella Resources (ASX:CR9) are chuffed with their MRE upgrade to Tampu, and so they should be after bringing total resources up 21% to a huge 24.7Mt kaolin deposit suitable for HPA feedstock.

The project now has an average yield of ~50% for 12.2Mt @ 36.5% Al2O3 of <45μm very high quality HPA feedstock specification while making a significant reduction in iron oxide (Fe203) top cut to just 0.9%.

Corella said for the MRE it used an Fe2O3 cut-off of <0.5%, lower than some peers are reporting their resources at.

Yet another bonus, Corella says its test work shows that the remaining 50% is suitable for the high-purity silica market which is used to make solar PV cells.

Corella sees a strong HPA market in the future as it feeds into the production of lithium-ion batteries and other high-end technologies.

Corella MD Tony Cormack says when the numbers are this good, they do all the talking.

“Having been part of many discoveries and mine start-ups over a long period, it’s fair to say this HPA focussed project at Tampu is shaping up as the best,” Cormack says.

“HPA is all about purity. The upgrade of the MRE at Tampu has delivered precisely what we set out to achieve as we press on towards production.

“Firstly, we have defined Australia’s best specification deposit of feedstock for HPA and secondly, we have defined a deposit that will support a substantial project over a long duration which will be better defined with our upcoming scoping study.

“HPA is all about purity and … to the unique and consistent nature of the Tampu mineralisation as defined in the upgraded MRE is a significant development for the project.

“Tampu is clearly the best deposit in Australia for HPA feedstock and the resource will support a long term HPA project.”
