APPIA DISCOVERS AN UNPRECEDENTED HIGH-GRADE MINERALIZED ZONE: TOTAL WEIGHTED AVERAGE GRADE OF 7,578 PPM OR 0.76% TOTAL RARE EARTH OXIDE ACROSS 10 REVERSE CIRCULATION DRILL HOLES AT ITS PCH IONIC CLAY PROJECT, BRAZIL

Appia Rare Earths & Uranium Corp. has further delineated 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 (see the Oct. 31, 2023, press release).

Highlights:

• High-grade SW extension zone:
  • 10 reverse circulation (RC) holes with a total weighted average of 7,578 parts per million (ppm) or 0.76 per cent total rare earth oxide (TREO), including:
    • 1,744 ppm, or 0.17 per cent, magnet rare earth oxide (MREO), 416 ppm, or 0.04 per cent, heavy rare earth oxide (HREO) and 7,162 ppm, or 0.71 per cent, light rare earth oxide (LREO);
    • The SW extension zone currently spans approximately 0.5 square kilometre with average hole depths of 19 metres -- all open at depth.
• Highest-grade RC and auger hole (AH) intercepts:
  • PCH-RC-067 from surface to 11 m EOH (end of hole):
    • 24,309 ppm, or 2.43 per cent, TREO, 5,717 ppm, or 0.57 per cent, MREO, 1,452 ppm, or 0.15 per cent, HREO and 22,857 ppm, or 2.29 per cent, LREO.
  • PCH-RC-066 from surface to 13 m EOH:
    • 12,858 ppm, or 1.29 per cent, TREO, 2,789 ppm, or 0.28 per cent, MREO, 524 ppm, or 0.05 per cent, HREO and 12,334 ppm, or 1.23 per cent, LREO.
  • PCH-RC-063 from surface to 24 m EOH:
    • 27,188 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, LREO.
  • Two auger holes have a total weighted average of 10,249 ppm, or 1.02 per cent, TREO, including:
    • PCH-AH-29 from surface to seven m EOH:
      • 4,122 ppm, or 0.41 per cent, TREO, 1,066 ppm, or 0.11 per cent, MREO, 361 ppm, or 0.04 per cent, HREO and 3,762 ppm, or 0.38 per cent, LREO.
    • PCH-AH-30 from surface to seven m EOH:
      • 16,375 ppm, or 1.64 per cent, TREO, 2,955 ppm, or 0.30 per cent, MREO, 457 ppm, or 0.05 per cent, HREO and 15,918 ppm, or 1.59 per cent, LREO.

"We believe that the high-grade nature of the SW extension zone, which contains magnet rare earth oxides sample values of up to 13,212 ppm, or 1.32 per cent, places this discovery on a global stage. The fact that all of these holes are still open at depth creates an opportunity to discover additional mineralization at depth," stated Tom Drivas, chief executive officer.

"Appia's work with exploratory auger drilling has delivered compelling results, particularly when the 2023 auger holes PCH-AH-29 and PCH-AH-30 are included, which returned a total weighted average of over 10,000 ppm, or plus-1-per-cent TREO over seven m of depth," noted Stephen Burega, president. "Follow-up RC drilling successfully expanded the overall total depth of the high-grade mineralization to an average of approximately 19 metres across this zone, and we've observed mineralization throughout the length of all RC and auger holes. For instance, holes PCH-RC-063 with a total depth of 24 m and PCH-RC-067 with a total depth of 11 m, each yielded grades exceeding 24,000 ppm, or 2.4 per cent, TREO and over 5,000 ppm, or 0.5 per cent, MREO at the bottom of each drill hole."

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 seven 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 SW 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 (see press release dated Nov. 9, 2023). The company will provide timely updates to investors as assay results are received from the remaining 85 RC, 128 auger and one 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 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 high-grade REEs and niobium mineral resources within the lateritic ionic adsorption clays.

Quality assurance/quality control (QA/QC)

Reverse circulation drill holes are vertical and reported intervals are true thicknesses. Each are sampled at one-metre intervals, resulting in average sample sizes of five kilograms to 25 kg. 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, and labeleld, 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 included its own control samples in each sample batch sent to the laboratory.

Quality control samples, such as blanks, duplicates and standards (CRM (certified reference materials)) were inserted into each analytical run. For all analytical 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 their measure of the concentration of rare earth elements (REE) analyses by inductively coupled plasma mass spectrometry (ICP-MS) analytical methods.
