Australian Critical Minerals maps out future plans for WA projects 

Australian Critical Minerals (ASX:ACM) is currently assessing a suite of follow-up work programs for its portfolio of critical minerals projects in Western Australia. 

As highlighted in the company’s quarterly report released today (29 April 2024) future work programs at the Cooletha Project include systematic soil sampling programs, geochemical analysis, surface investigation, and a reverse circulation drilling program. 

Soil programs will be planned on a regional scale across the Goldilocks Zone to identify and rank anomalous Cooletha Pegmatite Fields (CPFs). 

Geochemical analysis of soil and rock chip data will also be undertaken to determine the fertility of CPFs and to vector towards areas of higher fractionation. 

The company is also lining up further investigation into the rare earth mineralogy at its Rankin Dome Rare Earth Element (REE) Project, where there is an opportunity to improve REE recoveries through beneficiation and concentration prior to applying more aggressive lower pH leach conditions. 

More recently, preliminary leachability testing of selected reverse circulation drill samples completed by Australia’s Nuclear Science and Technology Organisation demonstrated the magnetic rare oxides comprise 21% to 23% of total rare earth oxides (TREO).

Results from Rankin Dome coincide with further, post-quarter assays from the Beverley Project, which returned grades up to 2,119 parts per million (ppm) TREO from moderately weathered granitic drill samples. 

The company announced last week that it was considering drilling beyond the kaolin zones at Beverley to test for REE mineralisation.  

During the previous quarter, Australian Critical Minerals uncovered pegmatites at surface, which the company says contributes to the ongoing development of the geological exploration model from rock sampling programs at Cooletha.

The samples returned head grades between 1,148 and 1,674ppm TREO, respectively.  

Australian Critical Minerals, which had $2.853 million in cash at hand at the end of the quarter, is an exploration company focused on developing a quality portfolio of critical minerals projects in Western Australia. 

The key projects are the Cooletha (Pilbara) Lithium Project and the Rankin Dome (Southern Cross) Rare Earth Project.
