APPIA ANNOUNCES ENCOURAGING INITIAL RESULTS FROM THE NEWLY IDENTIFIED TAYGETA AND MEROPE EXPLORATION TARGETS AT PCH PROJECT, BRAZIL

Appia Rare Earths & Uranium Corp. has released 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 kilometres east from target IV and the Buriti zone.
• 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 -- four m at 1,848 ppm TREO, 1,138 ppm HREO, 106 ppm Dy+Tb and 205 ppm Nd+Pr from one m;
  • PCH-AH-193 -- five m at 1,254 ppm TREO, 270 ppm HREO, 29 ppm Dy+Tb and 217 ppm Nd+Pr from one m;
  • PCH-AH-194 -- two m at 1,175 ppm TREO, 274 ppm HREO, 31 ppm Dy+Tb and 257 ppm Nd+Pr from four m;
  • PCH-AH-199 -- two m at 1,131 ppm TREO, 276 ppm HREO, 30 ppm Dy+Tb and 209 ppm Nd+Pr from two m;
  • PCH-AH-201 -- four m at 1,022 ppm TREO, 245 ppm HREO, 28 ppm Dy+Tb and 211 ppm Nd+Pr from two m;
  • PCH-AH-202 -- eight m at 1,696 ppm TREO, 1,070 ppm HREO, 101 ppm Dy+Tb and 172 ppm Nd+Pr from surface;
  • PCH-AH-204 -- five m at 1,267 ppm TREO, 754 ppm HREO, 75 ppm Dy+Tb and 168 ppm Nd+Pr from one m;
  • PCH-AH-207 -- six m at 1,025 ppm TREO, 262 ppm HREO, 29 ppm Dy+Tb and 196 ppm Nd+Pr from three m.
• The grade distribution signature found at depth in the auger drill holes is compatible with the pattern commonly found on IAC REE deposits.
• The Taygeta and Merope targets cover an area of 546 hectares 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 the table entitled "Intercepts from all auger holes on targets Taygeta and Merope." The full set of results are available on-line.

Tom Drivas, chief executive officer, 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, vice-president of 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 plus-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 favourable desorption results."

On March 1, 2024, the company announced its maiden mineral resource estimate on target IV and the Buriti zone, and the companion National Instrument 43-101 technical report on the PCH project was filed on April 16, 2024.

Quality assurance/quality control (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 five kilograms to 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 500 grams (g) each was obtained, bagged in a resistant plastic bag, labelled, 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, 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 ensure 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 its measure of the concentration of rare earth elements with the IMS95R analytical method that uses lithium metaborate fusion prior acid dissolution and inductively coupled plasma mass spectrometry (ICP-MS).

The technical information in this news release, including the information related to geology, drilling and mineralization, has been reviewed and approved by Mr. Costa, Appia's vice-president of exploration for Brazil, with more than 29 years of relevant experience. Mr. Costa is a fellow of the Australian Institute of Geoscientists (FAIG) and is a qualified person (QP) as defined by National Instrument 43-101 -- Standards of Disclosure for Mineral Projects.
