Toronto, Ontario--(Newsfile Corp. - May 14, 2024) - Appia Rare Earths & Uranium Corp. (CSE: API) (OTCQX: APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0) (the "Company" or "Appia") announced today the results from the newly identified exploration targets Taygeta and Merope. A total of 111 samples from 18 auger drill holes were assayed by SGS-GEOSOL Laboratories in Vespasiano, Brazil. The results confirm that the regolith developed over the Ipora Granite presented significant enrichment of Heavy Rare Earth Oxides (HREO), characteristic of the Ionic Adsorption Clay (IAC) rare earth elements (REE) deposits identified at other PCH target zones.

Stephen Burega, President, commented, "These initial results from the auger drill program are very promising, and provide us with a strong indication that the PCH project can host multiple new IAC REE mineralized areas in addition to the resource already identified in our maiden Mineral Resource Estimate (MRE) completed by SGS Canada. Additionally, these new target zones are considerably larger in total area as compared to the Target IV. Desorption test results will be reported once received."

Highlights

• The new targets are in the Eastern portion of the PCH claims, approximately 15 km East from Target IV and the Buriti Zone (see Figure 1).
• Selected intercepts for Heavy Rare Earth Oxide (HREO), Total Rare Earth Oxide (TREO), Dysprosium plus Terbium oxides (Dy+Tb) and Praseodymium plus Neodymium oxides (Nd+Pr) grades in Parts Per Millions (ppm):
  • PCH-AH-190 - 4m@1848ppm TREO, 1138ppm HREO, 106ppm Dy+Tb, 205ppm Nd+Pr from 1m.
  • PCH-AH-193 - 5m@1254ppm TREO, 270ppm HREO, 29ppm Dy+Tb, 217ppm Nd+Pr from 1m.
  • PCH-AH-194 - 2m@1175ppm TREO, 274ppm HREO, 31ppm Dy+Tb, 257ppm Nd+Pr from 4m.
  • PCH-AH-199 - 2m@1131ppm TREO, 276ppm HREO, 30ppm Dy+Tb, 209ppm Nd+Pr from 2m.
  • PCH-AH-201 - 4m@ 1022ppm TREO, 245ppm HREO, 28ppm Dy+Tb, 211ppm Nd+Pr from 2m.
  • PCH-AH-202 - 8m@1696ppm TREO, 1070ppm HREO, 101ppm Dy+Tb, 172ppm Nd+Pr from 0m.
  • PCH-AH-204 - 5m@1267ppm TREO, 754ppm HREO, 75ppm Dy+Tb, 168ppm Nd+Pr from 1m.
  • PCH-AH-207 - 6m@1025 ppm TREO, 262ppm HREO, 29ppm Dy+Tb, 196ppm Nd+Pr from 3m.
• The grade distribution signature found at depth in the auger drill holes is compatible with the pattern commonly found on IAC REE deposits (see Figures 2 and 3).
• The Taygeta and Merope targets cover an area of 546 and 1,134 hectares respectively.
• These first phase auger drill holes average 6.22 metres in depth, and most ended in mineralization leaving the interval open at depth.
• Intercepts of all auger drill holes are presented in Table 1. The full set of results are included in this LINK.

Tom Drivas, CEO, stated, "Building on our recent news confirming the presence of IAC mineralization through desorption testing, I am extremely excited by the identification of new, large scale targets across the PCH project which are underlain by the IAC mineralization produced by these weathered Ipora granites. We have a lot of work to do over the coming months to fully delineate these new target zones, and to assess the implications of their addition to our maiden MRE, and true value to the marketplace."

Andre Costa, VP Exploration for Brazil, commented, "The confirmation of these new targets opens the prospect of finding new exploration targets associated with the Ipora Granite across the entirety of the PCH project area which covers an impressive +40,000 hectares. Auger samples for desorbability testing are being prepared to corroborate the IAC REE mineralization in Taygeta and Merope targets. Delineation drilling will follow upon favorable desorption results."

On March 1^st, 2024, the Company announced its maiden Mineral Resource Estimate (MRE) on Target IV and the Buriti Zone (Click here for the Press Release), and the companion NI 43-101 technical report on the PCH Project was filed on April 16^th, 2024. (Click here for the Press Release)

QA/QC

Auger drill holes are vertical and reported intervals are true thickness. The material produced from drill holes are sampled at one metre intervals, resulting in average sample sizes of 5-10 kg. Quartering of the material 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 bagged samples are sent to the SGS laboratory in Vespasiano, Minas Gerais. In addition to the internal QA/QC of the SGS Lab, Appia includes its own control samples in each batch of samples sent to the laboratory.

Quality control samples, such as blanks, duplicates, and standards (CRM) 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 in each batch which comprise a full-length hole. The rigorous procedures are implemented during the sample collection, preparation, and analytical stages to insure the robustness and reliability of the analytical results.

All analytical results reported herein have passed internal QA/QC review and compilation. All assay results of Auger 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) with the IMS95R analytical method that uses lithium metaborate fusion prior acid dissolution and Inductively Coupled Plasma Mass Spectrometry (ICP-MS).
