Appia Deploys Third Drill at PCH Ionic Clay

Project in Brazil

Toronto, Ontario--(Newsfile Corp. - August 31, 2023) -

Appia Rare Earths & Uranium Corp.

(CSE:

API) (OTCQX: APAAF) (FSE: A0I0)

(the "Company" or "Appia")

Appia is pleased to announce the

deployment of a third drill on-site to investigate a significant geophysical anomaly at depth below Target

IV at Appia's PCH Ionic Adsorption Clay Project, Goias State, Brazil.

Summary:

Appia is currently using three (3) drills - one RC, one Auger, and one Diamond drill.

A comprehensive geophysical investigation has led to the identification of a significant magnetic

anomaly at over 300 metres and open at depth.

The initial target will be drilled to 250 metres depth to test both the ionic clay and hardrock

mineralization below Appia's priority ionic clay structures which reach an average depth from

surface of +/- 12 metres.

This program is designed to expand on the diamond drilling that was completed by the Vendor in

prior seasons.

"A study by a Brazilian Geographer/Geophysicist Master's student from the University of Brasilia was

conducted on Target IV of the PCH Project, where an induced polarization (IP) program as well as

detailed ground magnetics, and gamma surveys were carried out, inverted, and subsequently analyzed

by senior University, and Appia, geologists and geophysicists. This comprehensive investigation led to

the identification of a significant magnetic anomaly at over 300 metres and open at depth," commented

Stephen Burega, President.

"The arrival of the diamond drill marks a pivotal advancement in our exploration initiative. It underscores

our commitment to investigating not only the potential genesis of Ionic Adsorption Clay but also the

exciting opportunity for REE mineralization in hard rock formations," Burega continued.

The ongoing diamond drill hole operation aims to extend the investigation below the known ionic clay

through saprolite structures to greater depths of up to 250 metres to test the continuation of

mineralization at depth.

Furthermore, Appia's ongoing Reverse Circulation (RC) and auger drilling program of 300 holes is in full

swing. (See

). The Company's primary objective is to

accurately delineate the extent of the mineralized zone and to assess its economic significance.

To achieve this, a rigorous sampling procedure is being employed, including one-meter samples that will

be carefully collected and subsequently shipped to SGS Geosol laboratory. Assays from this program

are expected to be received within 2 months of being submitted.

Background on the PCH Project

The PCH Ionic Adsorption Clay Project is located within the Tocantins Structural Province in the Brasília

Fold Belt, more specifically, the Arenópolis Magmatic Arc. The PCH Project is 17,551.07 ha in size and

located within the Goiás State of Brazil. It is classified as an alkaline intrusive rock occurrence with highly

anomalous REE and Niobium mineralization. This mineralization is related to alkaline lithologies of the

Fazenda Buriti Plutonic Complex and the hydrothermal and surface alteration products of this complex

by supergene enrichment in a tropical climate. The positive results of the recent geochemical exploration

work carried out to date indicates great potential for REEs and Niobium within lateritic ionic adsorption

clays.
