Allup Silica Restricted (ASX: APS) (“Allup” or “Firm”) is happy to announce current exploration outcomes from its Pink Bark Challenge in southern WA has demonstrated the undertaking’s potential for uncommon earth components (REE), uranium, graphite and kaolin mineralisation.
Key factors
Additional evaluation carried out on samples from Allup’s 2023 drilling program has been returned with the next outcomes:
- Vital uranium outcomes as much as 232ppm U3O8 and REE as much as 980ppm for complete TREE of 1,212ppm.
- Highest grade of 1,985ppm complete uncommon earth oxide (TREO) in contemporary bedrock from drill gap PB019, 21 to 22m
- Vital REE anomalism found in supergene and bedrock over a 7km x 7km space.
- Kaolin sampling confirms ISO Brightness, grainsize, and XRD mineralogy in 4 places at Pink Bark Challenge.
- Uncooked insitu kaolin from Pink Bark is similar to Australian kaolin deposits presently in manufacturing and demonstrates a marketable product with doable co-product silica.
- Graphite-rich bedrock intersected within the south of E63/2371, particularly in drill gap PBAC058.
APS carried out extra evaluation from samples taken throughout its November 2023 drilling program at Pink Bark to check the underlying clays of licence E63/2138 for REE potential, and for thick kaolin accumulations over massive areas. The holes have been drilled to contemporary bedrock (blade refusal) the place doable, and the bedrock samples have been assayed for multi-element geochemistry.
The Albany Fraser Province has recorded a number of uranium occurrences. The mixed uncommon earth and uranium mineralisation at Pink Bark may be very important. Additional drilling is required to check the mineralisation for dimension and grade potential.
This launch focuses on the Kaolin, Uranium and Uncommon Earth potential of the Pink Bark Challenge following the outcomes of an air core drilling program that was accomplished in November 2023.
Introduction
The Pink Bark Challenge, contains three granted Exploration Licences and one pending software space, and is situated within the Albany Fraser Province’s Biranup zone, north of Esperance. The tenement was acquired to discover and develop silica sand, however quite a few current close by discoveries of REE clay- hosted deposits prompted Allup to think about the potential for such deposits on its tenement holdings.
The Biranup zone has been proven to be wealthy in worthwhile REE by the Geological Survey of Western Australia (GSWA) and fashionable explorers. Quite a few ASX-listed corporations have reported large areas of saprolitic clay enriched in uncommon earths overlying the Biranup late-stage granite intrusive rocks.
These deposits have been in comparison with China’s clay-hosted REE deposits, which have been a significant supply of REE for the nation’s battery trade. Within the Albany Fraser Province various carbonatites with uncommon earth potential have been reported and explored for uncommon earth mineralisation, and the Biranup granites are additionally quickly rising as a spotlight for exploration for clay and carbonatite-hosted uncommon earth deposits.

Kaolin
Allup’s earlier work on kaolin at Pink Bark was reported in ASX Launch dated 7 Might 2024, the place a major Exploration Goal was introduced. Further work to outline different traits have been really helpful and these are mentioned beneath.
Allup engaged Unbiased Metallurgical Operations Pty Ltd to finish additional mineralology, brightness and yellowness testing on 10 samples from 10 totally different drill holes.
Primarily based on the check work carried out on the ten samples from the Pink Bark Challenge, IMO concludes that the share passing 45 µm ranged from 22.7% to 62.4%, averaging 36.7%.
