Toronto, Ontario--(Newsfile Corp. - August 20, 2024) - Appia Rare Earths & Uranium Corp. (CSE: API) (OTCQX: APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0) (the "Company" or "Appia") 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.

Highlights

  • Discrete desorption interval samples from auger drillholes located on Ipora Granite lithology (see Map 1) returned recoveries up to:

  • The most significant recovered desorption intercepts for the main mineralized zone were:

    • PCH-AH-202 5m@59% TREO; 63% HREO; 85% NdPr; 72% TbDy from 3m.

    • PCH-AH-204 4m@54% TREO; 59% HREO; 71% NdPr; 56% TbDy from 2m.

    • PCH-AH-190 4m@47% TREO; 47% HREO; 61% NdPr; 55% TbDy from 1m.

    • PCH-AH-194 3m@40% TREO; 38% HREO; 68% NdPr; 36% TbDy from 3m.

    • PCH-AH-097 4m@34% TREO; 46% HREO; 55% NdPr; 48% TbDy from 2m.

    • PCH-AH-036 7m@37% TREO; 44% HREO; 63% NdPr; 47% TbDy from 3m.

  • The results of the main mineralized zone and from the full auger drillhole length from all tested drillholes are presented in Table 1 below. The full set of results are available through this LINK. The auger hole coordinates are presented in Table 2 below.

  • Desorbability tests were conducted by ALS using an Ammonium Sulfate solution at 0.5M, pH2, for 20 minutes at room temperature.
