Drilling Confirms the Carbonatitic Breccia High Grade Zone Mineralization
Toronto, Ontario--(Newsfile Corp. - January 22, 2025) - Appia Rare Earths & Uranium Corp. (CSE: API) (OTCQB: APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0) (the "Company" or "Appia") is excited to announce the geochemical assay results of its diamond drilling program on the high grade carbonatitic breccia located on the PCH project in the State of Goias, Brazil. The three drillholes (see Map 1) intercepted substantial Total Rare Earth Oxide (TREO), Niobium Oxide (Nb2O5) and Phosphate Oxide (P2O5) from the brecciated carbonatite intrusion identified in the Southwest Extension Zone of Target IV.
Tom Drivas, CEO stated: "The results from the first diamond drill holes are exceptional and would rank 2nd, 3rd, and 4thon the list of the best intercepts of the past year when compared to the recently reported results by MinerDeck, which highlighted the top REE intercepts of 2024. (Please Click Here) For all 3 drill holes to be mineralized with high grade rare earths from top to bottom highlights the enormous potential of the SW Extension zone. There is a strong case to be made that these results indicate that the PCH project could contain substantial high grade carbonatitic style rare earths in addition to Ionic Adsorption Clay (IAC) rare earth deposits. Mineralization is open at depth, northeast, northwest and southwest. We are currently developing plans for an expansion/resource-definition drilling program, and preliminary mineralogical-metallurgical test work on the diamond drill core from this program. These results exceed our expectations and increase our confidence in the success of our project."

97 intervals from the total of 516 presented samples resulted in 'overlimit readings' for La, and/or Ce, and/or Pr, and/or Nd, and/or Nb. These samples will go through new analysis methods and are likely to improve the overall results already achieved to date.
All three (3) Diamond Drillholes (DDH) ended in mineralization indicating a potential to extend the zone at depth, northeast, northwest and southwest.
The full set of results are available through this LINK. The diamond drillhole coordinates are available using this LINK.
Drivas continued: "When Appia's team originally identified the SW Extension zone boasting exceptionally high grade assay results (See press release dated November 28, 2023 - Click Here), we were operating under the assumption that the clay material we were sampling was similar to the mineralization found across the rest of Target IV's Ionic Adsorption Clay (IAC) zone. Upon further analysis and following the review of the hard rock assay results from our recent diamond drilling campaign released today, we are now confident that we are dealing with a separate style of mineralization akin to a high grade carbonatitic breccia and the results are stellar."
The location of the PCH project is extremely favorable with easy access to road and power infrastructure, and the Company enjoys a very friendly and supportive relationship with the local cattle farming community.

The grades by interval of TREO and Nb2O5 - P2O5 for the three drillholes are presented in Figures 2 and 3 below, respectively. Tracking Niobium and Phosphate is important because they represent key pathfinders in the identification of carbonatites.

Drillholes are inclined and reported intervals are apparent thickness. The material produced from the diamond drillholes are sampled at one metre intervals splitting the core in half, resulting in average sample sizes of 2-3 kg. The other Half core is kept in storage for further tests. The original core was logged and photographed.
The bagged samples are sent to the ALS laboratory in Goiânia, Goias for initial preparation and sent to Lima Peru for final analysis. In addition to the internal QA/QC of the ALS 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 three standard, one duplicate and one blank, introduced in each batch. Several batches were used to comprises the 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 DDH samples were provided by ALS, a Certified Laboratory, which performed their measure of the concentration of rare earth elements (REE) with the ME-MS81 analytical method that uses lithium borate fusion prior acid dissolution and Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Major Element Oxides were done using ME_ICP06 analytical method using lithium borate fusion and inductively coupled plasma atomic emission spectroscopy (ICP-AES). Au, Pt and Pd samples were analysed using the fire assay method PGM-ICP27. Desorption analysis with ME-MS19 analytical method was executed for the initial 35 metres of each drillholes with samples being leached with a solution of Ammonium Sulphate at 0.5 molar, pH 4, room temperature for 20 minutes. The leached solution content was analysed using ICP-AES/ICP-MS.
