Appia Announces Outstanding Total Rare Earth Oxide (TREO) Results From Its Diamond Drilling Program at PCH Project in Goias, Brazil

Rhea-AI Summary

Appia Rare Earths & Uranium Corp (APAAF) has announced exceptional results from its diamond drilling program at the PCH project in Goias, Brazil. The program revealed significant Total Rare Earth Oxide (TREO), Niobium Oxide, and Phosphate Oxide concentrations in three drillholes from a brecciated carbonatite intrusion.

Key findings include:

• PCH-DDH-002: 150m@1.14% TREO from surface
• PCH-DDH-003: 147.7m@1.69% TREO from surface
• PCH-DDH-004: 153m@1.08% TREO from surface

All three drillholes ended in mineralization, suggesting potential for extension. The discovery indicates the presence of high-grade carbonatitic style rare earths in addition to Ionic Adsorption Clay deposits. The project benefits from favorable location with easy access to road and power infrastructure.

Positive

• Exceptional drilling results ranking 2nd, 3rd, and 4th among best REE intercepts of 2024
• High-grade mineralization from surface to bottom in all three drillholes
• Mineralization remains open at depth and in multiple directions
• Strategic location with existing infrastructure access
• 97 samples exceeded measurement limits, suggesting potential for even better results

Negative

• None.

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 2^nd, 3^rd, and 4^th on 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."

Highlights:

• Hole PCH-DDH-002 150 metres@1.14% TREO; 0.12% Nb2O5; 2.76% P2O5 from Surface

  • including 12 metres@2.54% TREO; 0.21% Nb2O5; 9.52% P2O5 from 37 metres

  • including 20 metres@1.75% TREO; 0.13% Nb2O5; 2.8% P2O5 from 81 metres

  • including 18 metres@2.03% TREO; 0.14% Nb2O5; 2.29% P2O5 from 132 metres

• PCH-DDH-003 147.7 metres@1.69% TREO; 0.18% Nb2O5; 3.26% P2O5 from Surface

  • including 58 metres@2.19% TREO; 0.26% Nb2O5; 5.18% P2O5 from Surface

  • including 17 metres@1.87% TREO; 0.11% Nb2O5; 1.44% P2O5 from 117 metres

• PCH-DDH-004 153 metres@1.08% TREO; 0.15% Nb2O5; 2.31% P2O5 from Surface

  • including 10 metres@2.16% TREO; 0.24% Nb2O5; 3.22% P2O5 from 10 metres

  • including 9 metres@3.08% TREO; 0.24% Nb2O5; 7.37% P2O5 from 42 metres

  • including 18 metres@1.01% TREO; 0.26% Nb2O5; 3.15% P2O5 from 135 metres

• 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.

QAQC

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.
