Appia Rare Earths & Uranium Corp. announced the further delineation of the SW Extension Zone, a significant high- grade Rare Earth Elements (REE) mineralized zone located in the Southwest (SW) corner of the Target IV zone. This discovery spans an area of over 1,000 metres by 500 metres, with an average thickness of approximately 19 metres, and builds on the previously announced remarkable PCH-RC- 63 results.

The lateral extension and the depth of the SW Extension high-grade zone has not been fully tested, and the Company eagerly awaits results from the remaining 7 RC holes drilled within this new zone, in addition to the numerous RC drill holes to the south located outside of the Target IV boundary. Target IV encompasses 1,702 hectares, with the Southwest extension zone occupying about 50 hectares. In total, the PCH project spans 17,551 hectares.

Appia has previously provided details on a total of 57 RC drill holes, showcasing an extraordinary overall total weighted average grade of 2,287 ppm TREO. The Company will provide timely updates to investors as assay results are received from the remaining 85 RC, 128 Auger, and 1 diamond drill holes which are located both within Target IV and from various extension zones outside of the main Target IV zone. Background on the PCH Project The PCH Project is located within the Tocantins Structural Province in the Brasília Fold Belt, more specifically, the Arenópolis Magmatic Arc.

The PCH Project is 17,551.07 ha in size and located within the Goiás State of Brazil. It is classified as an alkaline intrusive rock occurrence with highly anomalous REE and Niobium mineralization. This mineralization is related to alkaline lithologies of the Fazenda Buriti Plutonic Complex and the hydrothermal and surface alteration products of this complex by supergene enrichment in a tropical climate.

The positive results of the geochemical exploration work carried out to date indicates the potential forhigh-grade REEs and Niobium mineral resources within the lateritic ionic adsorption clays.
