APPIA CLOSES NON-BROKERED PRIVATE PLACEMENT, COMPLETES AUGER DRILLING AT GAIA, SHIPS SAMPLES TO THE LAB, AND ADVANCES A NEW AUGER PHASE AT TAYGETA - PCH PROJECT (GOIAS, BRAZIL)

Appia Rare Earths & Uranium Corp. has completed the auger drilling campaign at the Gaia target and the advancement of a new auger phase at the Taygeta target, both within the PCH rare earths project (ionic-adsorption clay (IAC)) in Goias state, Brazil.

At Gaia, Appia completed 90 auger drill holes, and all samples have been shipped to an accredited laboratory for geochemical and desorption analyses; the company is awaiting analytical certificates to guide upcoming technical decisions. In parallel, the program at Taygeta remains under way, with 42 auger drill holes completed to date, prioritizing near-surface horizons selected using geological, geomorphological and detailed magnetometry criteria consistent with IAC systems. The program employs two recently acquired auger rigs to accelerate area coverage and enhance model resolution.

Based on the project's technical record, the company will apply to Gaia the same desorption protocol that has delivered excellent performance at the Taygeta target -- an (NH4)2SO4 0.5 M solution at pH 4, under ambient temperature -- enabling direct comparability of results and supporting IAC-focused target prioritization.

"We successfully wrapped up the auger program at Gaia and have already shipped the samples for analysis. At the same time, we continue to progress efficiently at Taygeta, expanding coverage over areas that exhibit favourable signatures for ionic-adsorption clay mineralization within the PCH project," said Tom Drivas, chief executive officer and director.

Next steps

The company will release the Gaia results -- covering geochemistry and pH 4 desorption using (NH4)2SO4 0.5 M when available -- and integrate them into the project's geological-geometallurgical model, while continuing auger drilling at Taygeta with infill and stepouts guided by terrain morphology, drainage and magnetic response.
