Appia Rare Earths & Uranium Corp. reported significant assay results from its discovery Diamond Drill Hole (DDH) PCH-F01, located within the highly prospective Target IV zone at its PCH ionic adsorption clay project in Brazil. Appia has re-assayed the entire hole PCH-F01 as part of its due diligence, and assay results from surface to 18 metres include 9,445 parts per million (ppm) Total Rare Earth Oxide (TREO), 2,786 ppm Magnet Rare Earth Oxide (MREO), 787 ppm Heavy Rare Earth Oxide (HREO), and 8,658 ppm Light Rare Earth Oxide (LREO).

DDH PCH-F01, originally drilled vertically to 100 metres depth during the vendors' exploration campaign in 2021, has been re-assayed and updated with the nomenclature DDH PCH-F1R. This hole intercepted a high-grade mineralized weathered profile to bedrock, spanning from the surface to 18 metres. The re-assaying confirmed the presence of continued high-grade mineralization throughout the intercepted hard rock zone, with the mineralization continuing until the end of drill hole at 100 metres depth.

Highlights: Composite results across 100 metres: 3,577 ppm or 0.36% TREO including 968 ppm or 0.10% MREO, 293 ppm or 0.03% HREO, and 3,284 ppm or 0.33% LREO. Including 1.5 metres at 30,642 ppm or 3.06% TREO, 11,219 ppm or 1.12% MREO, 2,434 ppm or 0.24% HREO, and 28,208 ppm or 2.82% LREO from 2m to 3.5m.
