Toronto, Ontario--(Newsfile Corp. - June 5, 2024) - Appia Rare Earths & Uranium Corp. (CSE: API) (OTCQX: APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0) (the "Company" or "Appia") is pleased to announce the beginning of their summer uranium exploration season for 2024. To start, Appia recently completed a ground reconnaissance and exploration program for their uranium-bearing Eastside property located in the Peter Lake Domain, east of Wollaston Lake. Appia followed up on several uranium, rare earth element, and platinum group element targets brought to light during the company's Mineral Prospectivity Map Analysis conducted in 2023 (Figure 1). As a result, the company collected:

• Sixty-three (63) hand samples, five (5) of which read 10,000 - 53,000 counts per second (cps) from two (2) main uranium-bearing pegmatite-hosted mineralization trends, with additional potential for rare earth elements (REE) and platinum group metals (PGM),

• 403 geological stations for lithological study.

Stephen Burega, President stated: "This is an excellent start to the 2024 summer exploration season. Our ground crew discovered several new uranium-hosting targets with potential for REE and PGM elements, allowing us to gain the insight we need for future programs. Appia's 2024 Eastside exploration program signifies its commitment to the exploration and development of its four (4) Saskatchewan uranium properties and highlights the Company's commitment to participating in this surging uranium market."

Appia now awaits lab assay results to confirm the exact contents of each sample, which are being shipped to the SRC Geo-Analytical Lab in Saskatoon for analysis. Once acquired, these results will be promptly released to the public.
