APPIA REPORTS NEW ASSAY RESULTS INCREASING THE TOTAL WEIGHTED AVERAGE TO 2,287 PPM TREO ACROSS 57 RC DRILL HOLES AT ITS PCH IONIC CLAY PROJECT, BRAZIL

Appia Rare Earths & Uranium Corp. has released the outstanding assay results from the latest 39 drill holes, part of a comprehensive 147-hole reverse circulation (RC) drilling program. The total weighted average across 57 RC drill holes reported to date is 2,287 parts per million (ppm) or 0.23 per cent total rare earth oxides (TREO). The PCH ionic clay project continues to showcase impressive distribution, width and grades, underscoring its significant potential.

Summary:

• Overall grade:
  • Total weighted average of 2,287 parts per million (ppm) or 0.23 per cent total rare earth oxides (TREO) across 57 RC drill holes reported to date, including:
    • 542 ppm or 0.054 per cent magnet rare earth oxides (MREO);
    • 167 ppm or 0.017 per cent heavy rare earth oxides (HREO).
• Highest-grade intercepts:
  • PCH-RC-051 from zero to 11 metres end of hole (EOH):
    • 9,279 ppm or 0.93 per cent TREO, and 2,138 ppm or 0.21 per cent MREO, and 464 ppm or 0.046 per cent HREO, including:
      • 14,166 ppm or 1.42 per cent TREO across four m (from three m to seven m) with 3,217.05 ppm or 0.32 per cent MREO, and 662 ppm or 0.066 per cent HREO;
      • 10,098 ppm or 1.01 per cent TREO across three m (from eight m to 11 m EOH) with 2,483 ppm or 0.25 per cent MREO and 550 ppm or 0.05 per cent HREO;
  • PCH-RC-063 from zero to 24 m EOH:
    • 27,189 ppm or 2.72 per cent TREO, 6,293 ppm or 0.63 per cent MREO, 1,369 ppm or 0.14 per cent HREO, and 25,819 ppm or 2.59 per cent light rare earth oxides (LREO) (previously reported; see Oct. 31, 2023, press release).

"Appia has doubled the average depth of the mineralized zones to over 13 metres, and we now have a total weighted average of 2,287 ppm TREO across all reported drill holes each with significant magnet elements present," commented Stephen Burega, president. "With this set of results, we can see that the potential of Target IV in terms of distribution, grade and thickness of mineralization is well beyond our initial expectations."

"Results from holes like PCH-RC-063 and PC-RC-051 with very high-grade mineralization further validate our understanding and excitement of the project's geology," commented Carlos Bastos, geology manager and Appia's Brazilian qualified person.

"It is very encouraging for Appia to see more high-grade results occurring within the Target IV area," stated Tom Drivas, chief executive officer. "Appia will be working with SGS Geological Services to complete a comprehensive NI 43-101 technical report and mineral resource estimate (MRE) on Target IV over the coming months, capitalizing on the promising results we are getting from our recent drilling."

Appia will provide timely updates to shareholders and the general public as assay results are received from the remaining 90 RC holes, 106 auger holes and one diamond drill hole. The attached tables exclude results from the pending six RC holes yet to be received by the company -- RC-PCH-053, 054, 057, 058, 061 and 062.

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 vertical and reported intervals are true widths. Each 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.
