Appia Reports Extraordinary Assay Drill Results From Its PCH Ionic Clay Project, Brazil

Reverse Circulation Drill Hole Returns 24 Metres Of Mineralization Averaging 27,188 ppm or 2.72% Total Rare Earth Oxides From Surface

TORONTO, October 31st, 2023 - Appia Rare Earths & Uranium Corp. (the “Company” or “Appia”) (CSE: API) (OTCQX: APAAF) (Germany: “A0I0.F”, “A0I0.MU”, “A0I0.BE”) is thrilled to announce a groundbreaking discovery of an exceptional high-grade Total Rare Earth Oxides (TREO) intersection extending the known area of Target IV. Hole PCH-RC-063 contains unique high grades and depth of mineralization, spanning an impressive 24 metres from top to bottom, and remains open at depth.

Summary:

27,188 parts per million (ppm) or 2.72% TREO over 24 metres
Including 6,293 ppm or 0.63% Magnet Rare Earth Oxides (MREO)
Including 1,369 ppm or 0.14% Heavy Rare Earths Oxides (HREO)
PCH-RC-63 totalled 24 metres depth and is mineralized throughout the entire hole from surface, and remains open at depth.
Notably, several elements surpassed the upper detection limit of the assay method being used, and updated results will be reported once received.

“These drill results are the highest TREO grades detected on the PCH property to date,” commented Tom Drivas, CEO. “The data released today reveals an unprecedent concentration of TREO over the entire hole, and even more impressive is that the hole remains open at depth, suggesting significant potential for further mineralization.”

“This extraordinary RC hole confirms the extension of the initial Target IV area to the West and has increased the average thickness and total depth of the highly mineralized PCH ionic clay horizon,” said Stephen Burega, President. “These high concentrations of TREO are very uncommon, and may be the first indications of a larger high-grade mineralized zone. Lastly, we have not yet tested the total thickness of this zone as the RC drilling was stopped at the water table.”

“The consistency of grades is truly spectacular. At the bottom one metre of the hole, in sample F485895, we observed grades of 26,882 ppm of TREO, 5,897 ppm of MREO, and 1,245 ppm of HREO,” stated Carlos Bastos, Geology Manager and Appia’s Brazilian Qualified Person. “The assay results from PCH-RC-063 are highly promising, revealing sustained mineralization of essential elements including Terbium (Tb), Dysprosium (Dy), Neodymium (Nd), and Praseodymium (Pr). Notably, several elements surpassed the upper detection limit of the assay method being used, and updated results will be reported once received.”

In light of these findings, Appia has commissioned a comprehensive analyses for each rare earths oxide using the methods IMS95RS and ICP95A from SGS Geosol Lab to further understand the potential implications that this level of mineralization could have on the project.

Appia will provide timely updates to shareholders and the general public as assay results are received from the remaining 129 RC, 106 Auger, and 1 diamond drill holes.
