Appia Confirms Outstanding Desorption Results From Its Ionic Adsorption Clay Targets Maia, Electra, Taygeta and Merope in Goias, Brazil
Appia Rare Earths & Uranium Corp. (CSE: API | OTCQX: APAAF)
A publicly traded Canadian company in the rare earth element and uranium sectors.
TORONTO, ON, August 20th, 2024, Appia Rare Earths & Uranium Corp. (the “Company” or “Appia”) (CSE: API) (OTCQX: APAAF) (FWB: A0I0) (MUN: A0I0) (BER: A0I0) announced today the initial desorption test results from the Ionic Adsorption Clay (IAC) rare earth elements (REE) targets Maia, Electra, Taygeta and Merope at the PCH project. A total of 89 samples from 13 auger drillholes were sent to ALS Laboratories in Lima, Peru (ALS), and the results consistently confirmed the REE IAC mineralization style on all targets developed over the Ipora Granite. The results show very good recoveries of Magnet Rare Earth Oxides (MREO) and Heavy Rare Earth Oxides (HREO)..
Stephen Burega, President, said, “The four (4) new targets are showing higher levels of heavy rare earths as we continue to explore to the East of the property, with excellent Dy and Tb recovery values at Merope and Taygeta targets, representing a significant increase in desorption levels. These are important results that demonstrate further that we have discovered a notable ionic clay rare earths deposit. Our project has many superior characteristics including its hosting in easy to dig clays, a desirable diversity of metals including the “rare” rare earths, the high grades encountered and the large scope of the project. Industry has a growing need for rare earths in a stable and western jurisdiction and we are committed to offer a solution.”
Drill crews are working daily in order to expand the IAC mineralization over this significant project area. The Company continues to see very favourable kinetics across all of the ALS desorption testing. With these increases in Dysprosium (Dy) and Terbium (Tb) recoveries, the PCH project continues to demonstrate its potential as a future source for these extremely important minerals for the permanent magnet industry.

Andre Costa, VP Exploration for Brazil, commented, “These exciting results confirm the potential for REE Ionic Desorption Clay mineralization on all tested new targets. All of them over the Ipora Granite. We are on the right path in characterizing the Maia, Electra, Taygeta and Merope targets in the PCH Project and we will continue to focus drilling on these new targets to determine recoverability and delineate their extension since they remain open on all directions.”
On March 1st, 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 16th, 2024. (Click here for the Press Release )

QAQC
Auger drillholes are vertical and reported intervals are true thickness. The material produced from auger 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 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 two standard, one duplicate and one blank, introduced in each batch which comprises full-length hole(s). 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 RC 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). Desorption analysis with ME-MS19 analytical method with samples being leached with a solution of Ammonium Sulphate at 0.5 molar, pH 2, room temperature for 20 minutes. The leached solution content was analysed using ICP-AES/ICP-MS.
