APPIA ACQUIRES TWO NEW AUGER DRILLS AND LAUNCHES NEW DRILL PROGRAM AT GAIA TARGET ADJACENT TO TAYGETA AND MEROPE, PCH REE PROJECT, BRAZIL

Appia Rare Earths & Uranium Corp. has acquired two auger drill rigs and initiated phase 1 of a new 241-hole auger campaign, which will begin with the first 100 holes. These first holes will test the newly defined Gaia target, located adjacent to the Taygeta and Merope zones within the PCH rare earth element (REE) project in Goias state, Brazil. This area was selected for its strong geological and geophysical similarities to Taygeta and Merope, where previous drilling identified high-grade, shallow ionic-adsorption clay (IAC) mineralization. Drilling is scheduled to begin by Aug. 1, 2025.

"With this drilling phase, we aim to evaluate the newly identified Gaia target, which shares the same geological and geophysical characteristics as the Taygeta and Merope zones. Our objective is to complete infill drilling to confirm the rare earth potential of the area and further define additional mineralized zones to support the project's continued advancement," said Tom Drivas, chief executive officer and director.

The auger drilling campaign will now focus on the Gaia target, aiming to evaluate whether it hosts comparable rare earth element potential. While no geochemical analyses have yet been conducted in Gaia, its striking resemblance in terrain, lithology and magnetic response to Taygeta and Merope -- zones that returned excellent TREO grades with highly favourable desorption characteristics -- make it a priority for phase 1 exploration (see news release dated Feb. 4, 2025).

The PCH property sits on gently rolling terrain with convenient infrastructure just 15 minutes from a nearby mining town.

Appia's PCH project hosts two distinct styles of critical rare earth element (CREE) mineralization: ionic adsorption clays (IAC) and high-grade carbonatitic breccia.

Rare earths contained in IAC are typically more easily extractable, offering significantly lower operating (opex) and capital costs (capex). This is due to the simple extraction process, which avoids blasting, crushing and milling -- eliminating the generation of tailings and the need for a tailings storage facility. Instead, the material is amenable to leaching using ammonium sulphate, a common and cost-effective fertilizer.

The PCH project contains significant amounts of heavy rare earths needed to meet the increasing demand for permanent magnets used in electric vehicles and other application in the clean energy transition.

About Appia Rare Earths & Uranium Corp.

Appia is a publicly traded Canadian company in the rare earth element and uranium sectors. The company holds the right to acquire up to a 70-per-cent interest in the PCH ionic adsorption clay project (see June 9, 2023, press release) which is 42,932.24 hectares in size and located within the Goias state of Brazil (see Jan. 11, 2024, press release). The company is also focusing on delineating high-grade critical rare earth elements and gallium on the Alces Lake property, and exploring for high-grade uranium in the prolific Athabasca basin on its Otherside, Loranger, North Wollaston and Eastside properties. The company holds the surface rights to exploration for 94,982.39 hectares in Saskatchewan.
