Appia Successfully Concludes Diamond Drilling Program Intercepting Potential Highgrade Mineralization on all three Drillholes in Goias, Brazil

Toronto, Ontario--(Newsfile Corp. - November 12, 2024) - Appia Rare Earths & Uranium Corp. (CSE: API) (OTCQB: APAAF) (FWB: A0I0) (MUN: A0I0) (BER: A0I0) (the "Company" or "Appia") is excited to announce the conclusion of its diamond drilling program in the SouthWest Extension Zone of Target IV at its Ionic Adsorption Clay (IAC) project in the State of Goias, Brazil. The three drillholes (see Map 1) were completed for a total of 450.7 metres, and successfully intercepted the anticipated carbonatitic breccia and highly altered hardrock zones in all three drillholes, indicating the continuation of the highgrade mineralization first identified in previously completed reverse circulation drill holes (See press releases dated October 31^st, 2023 and January 16, 2024).

Highlights:

• Hole PCH-DDH-002, total depth of 150.0metres - Regolith fom 0 to 37.4m, Breccia from 37.4 to EOH
• Hole PCH-DDH-003, total depth of 147.7metres - Regolith fom 0 to 49.9 m, Breccia from 49.9 to EOH
• Hole PCH-DDH-004, total depth of 153.0metres - Regolith fom 0 to 45.0 m, Breccia from 45.0 to EOH
• The three drillholes presented substantial hydrothermal alteration and local sulfidation within the breccia.

Stephen Burega, President, stated, "The program successfully identified carbonatitic breccia below the previously reported highgrade clay material with up to 92,758 ppm or 9.3% and averaging over 27,000 ppm or 2.7% Total Rare Earth Oxide (TREO) over 0-24 metres. (See press release January 16, 2024) And we anticipate a continuation of similar grades below this zone in the hardrock mineralization at depth. This presents an exceptional opportunity to further showcase Target IV and the entire PCH project, for both IAC and primary mineralization potential."

The preliminary geological interpretation is presented in Figure 1 showing the extent of the Hydrothermalized Carbonatitic Breccia, which remains open at depth. Sampling is under way and assay results are expected in +/- 30 days.
