APPIA REPORTS EXTRAORDINARY ASSAY DRILL RESULTS FROM ITS PCH IONIC CLAY PROJECT, BRAZIL

Appia Rare Earths & Uranium Corp. has made 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 per cent TREO over 24 metres;
  • Including 6,293 ppm or 0.63 per cent magnet rare earth oxides (MREO);
  • Including 1,369 ppm or 0.14 per cent 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;
• Previously announced drill results -- press release Oct. 16, 2023.

"These drill results are the highest TREO grades detected on the PCH property to date," commented Tom Drivas, chief executive officer. "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 reverse circulation holes, 106 auger holes and one diamond drill hole.

Background on the PCH project

The PCH project is located within the Tocantins structural province in the Brasilia fold belt, more specifically, the Arenopolis magmatic arc. The PCH project is 17,551.07 hectares in size and located within the Goias state of Brazil. It is classified as an alkaline intrusive rock occurrence with highly anomalous rare earth element 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 recent geochemical exploration work carried out to date indicate the potential for REEs within lateritic ionic adsorption clays and niobium.

Quality assurance/quality control

Reverse circulation (RC) drill holes are sampled at one-metre intervals, resulting in higher average sample sizes of five to 25 kilograms. A small representative specimen was taken from each sample bag and placed into a chip tray for visual inspection and logging by the geologist. Quartering was performed at Appia's logging facility using a riffle splitter and continued splitting until a representative sample weighing approximately 500 grams each was obtained, bagged in a resistant plastic bag, labelled, photographed and stored for shipment.

The samples were sent to the SGS laboratory in Vespasiano, Minas Gerais. In addition to the internal QA/QC of the SGS lab, Appia has used its own control samples in each batch sent to the laboratory.

Quality control samples, such as blanks, duplicates and standards (certified reference materials), were inserted into each analytical run. For all analysis methods, the minimum number of QA/QC samples is one standard, one duplicate and one blank, introduced every batch which comprise a full-length hole. The rigorous procedures implemented during the sample collection, preparation and analysis stages underscore the robustness and reliability of the analytical results obtained.

All analytical results reported herein have passed internal QA/QC review and compilation. All assay results of RC samples were provided by SGS Geosol, an ISO/IEC 17025:2005 certified laboratory, which performed its measure of the concentration of rare earth elements (REE) analyses by inductively coupled plasma mass spectrometry (ICP-MS) analytical methods.
