Appia Acquires Two New Auger Drills and

Launches New Drill Program at Gaia Target

Adjacent to Taygeta and Merope, PCH REE

Project, Brazil

Toronto, Ontario--(Newsfile Corp. - July 29, 2025) - Appia Rare Earths & Uranium Corp.

(CSE: API)

(OTCQB: APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0)

(the "

Company

" or "Appia")

is pleased to

announce it 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 Goiás

State, Brazil (Figure 1). 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 August 1st, 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, CEO & 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 favorable desorption characteristics—makes it a

priority for Phase 1 exploration (see

News Release

dated February 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 sulfate, 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 EVs and other application in the clean energy transition.
