Appia Announces Corrected Target IV Total Area

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. (CSE: API) (OTCQX: APAAF) (FSE: A0I0.F) (FSE: A0I0.MU) (FSE: A0I0.BE) (the ‘Company’ or ‘Appia’) is pleased to announce that, further to the press release issued earlier today, the total area shown for Target IV has been updated to 193 hectares, and 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. (See Oct. 31st, 2023 Press Release). The Press Release issued earlier today erroneously listed the total area shown for Target IV as 1,702 hectares, rather than 193 hectares.

Highlights:

High-Grade SW Extension Zone:

10 Reverse Circulation (RC) holes with a total weighted average of 7,578 ppm or 0.76% Total Rare Earth Oxide (TREO), including:

1,744 ppm or 0.17% Magnet Rare Earth Oxide (MREO), and 416 ppm or 0.04% Heavy Rare Earth Oxide (HREO); 7,162 ppm or 0.71% Light Rare Earth Oxide (LREO)

The SW Extension Zone currently spans approximately 0.5 km2 with average hole depths of 19 metres – all open at depth.

Highest-Grade RC and Auger (AH) Intercepts:

PCH-RC-067 from 0 to 11m EOH:

24,309 ppm or 2.43 % TREO, 5,717 ppm or 0.57% MREO, 1,452 ppm or 0.15% HREO, and 22,857 ppm or 2.29% LREO.

PCH-RC-066 from 0 to 13m EOH:

12,858 ppm or 1.29% TREO, 2,789 ppm or 0.28% MREO, 524 ppm or 0.05% HREO, and 12,334 ppm or 1.23% LREO.

PCH-RC-063 from 0 to 24m EOH:

27,188 ppm or 2.72% TREO, 6,293 ppm or 0.63% MREO, 1,369 ppm or 0.14% HREO, and 25,819 ppm or 2.59% LREO.

2 AH holes have a total weighted average of 10,249 ppm or 1.02% TREO, including:

PCH-AH-29 from 0 to 7m EOH:

4,122 ppm or 0.41% TREO, 1,066 ppm or 0.11% MREO, 361 ppm or 0.04% HREO, and 3,762 ppm or 0.38% Light Rare Earth Oxides (LREO).

PCH-AH-30 from 0 to 7m EOH:

16,375 ppm or 1.64% TREO, 2,955 ppm or 0.30% MREO, 457 ppm or 0.05% HREO, and 15,918 ppm or 1.59% Light Rare Earth Oxides (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%, 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, CEO.

‘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 +1% TREO over 7m 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 24m and PCH-RC-067 with a total depth of 11m, each yielded grades exceeding 24,000 ppm or 2.4% TREO and over 5,000 ppm or 0.5% 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 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 193 hectares, with the Southwest extension zone occupying about 50 hectares. In total, the PCH project spans 17,551 hectares across 10 claims.

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 November 9, 2023). 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.

QA/QC

Reverse circulation (RC) drill holes are vertical and reported intervals are true thicknesses. Each are sampled at one metre intervals, resulting in average sample sizes of 5-25 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 500g each was obtained, bagged in a resistant plastic bag, labeled, 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) 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.
