Further drill results from the Caralue Bluff regolith hosted REE – Kaolin Prospect return thick, high-grade intervals of REE mineralisation in the clay rich weathering profile, consolidating and expanding the area of REE mineralisation
Intersections at Caralue Bluff include:
• CBAC22-071 – 12m @ 2,343 ppm TREO from 9m
• CBAC22-074 – 17m @ 1,774 ppm TREO from 4m
• CBAC22-068 – 12m @ 1,326 ppm TREO from 6m
• CBAC22-013 – 16m @ 776 ppm TREO from 2m
• CBAC22-064 – 12m @ 784 ppm TREO from 11m
• CBAC22-055 – 15m @ 747 ppm TREO from 4m
These results infill and expand the thick, high-grade nature of clay hosted REE mineralisation in the south-east of the prospect
Results from a further 27 drill holes are reported here with over 100 drill holes still to be reported
All drill results are expected by the end of July
Exploration Results for Rare Earth Element Projects can be a bit more complicated than for projects targeting metals like Gold and Copper. WATCH iTech Minerals Managing Director Mike Schwarz explains what you need to know and what to look out for.
iTech Minerals (ASX: ITM,) completed a 478-hole drill program, in April 2022, across four prospects on the Eyre Peninsula in South Australia. The aim of the program was to test the potential for regolith hosted ion adsorption clay (IAC) REEs and high purity kaolin mineralisation. The fourth batch of drill results, from Caralue Bluff, show that significant intersections of REEs occur within the kaolin (clay) rich weathered horizon over larger areas (Figures 1 & 2). Metallurgical work on 60 mineralised samples from Caralue Bluff are currently undergoing leaching test work with results due within the next 4 weeks. Further samples are being prepared for leaching test work as drill results become available.
Caralue Bluff Prospect
The Caralue Prospect was initially established as a high purity kaolin prospect with the identification of thick intervals of bright white kaolin, close to surface, in several historical drill holes. Having identified significant REEs in the kaolin rich intervals at Ethiopia, Burtons and Bartels Prospects, iTech geologists suspected that Caralue Bluff might also be prospective for regolith hosted REE mineralisation. The latest results extend and infill the areas of thick, high-grade REEs, particularly in the south-east of the prospect area. A total area of 12 km x 12 km was tested by drilling of 260 holes, the results of which will determine the continuity of mineralisation within this already extensive area.
