Appia Announces Drilling Updates on ULTRA HARD ROCK Targets in Brazil

Appia Rare Earths & Uranium Corp. (CSE: API) (OTCQB: APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0) is pleased to announce that Ultra Rare Earth Inc. is continuing with the diamond drill program, announced by Appia in its press release dated October 22, 2025, on the High Grade Zone on the project formerly known as the PCH Project. Ultra acquired a 50% interest in the PCH Project on October 31, 2025 (see Press Release dated November 3, 2025).

Ultra is now the Operator of the PCH project. The High-Grade Zone has been renamed the ULTRA HARD ROCK carbonatite Target. The diamond drilling program under the supervision of Ultra continues to intercept carbonatitic breccia from surface to the end of hole.

Ultra is continuing with the auger drilling commenced by Appia in August on the Taygeta, Merope and Gaia targets, which have been renamed the ULTRA IAC target and comprise the Taygeta, Merope and Gaia sectors respectively, confirming expansion in the area of the Ionic Adsorption Clay (IAC) Rare Earth Elements (REE). Appia holds a 25% interest in the ULTRA Hardrock and ULTRA IAC Projects, which is 42,932.24 ha. in size and located within the state of Goiás in Brazil.

Highlights

• ULTRA HARD ROCK – 7,000 metres drilling campaign underway with three diamond drill rigs.
• ULTRA HARD ROCK – 7 new drillholes already completed (1,513.5 metres) intercepting the carbonatite on all their extensions.
• ULTRA HARD ROCK – Carbonatite intrusion remains open in all directions.
• ULTRA HARD ROCK – The drillholes of this campaign are an extension of the three drillholes PCH-DDH-002, PCH-DDH-003, PCH-DDH-004 executed in 2024 that intercepted 150m @ 1.34% TREO, 0.13% Nb2O5 from surface; 147m @ 2.00% TREO, 0.23% Nb2O5 from surface; 153m @ 1.32% TREO, 0.20% Nb2O5 from surface respectively (see Press Release dated March 10^th 2025).
• ULTRA HARD ROCK – Carbonatite was intercepted at 300 metres true vertical depth and remains open at depth.
• ULTRA IAC – 244 auger drillholes completed.

“The drill core results from the first three diamond drill holes of the October 2025 drill program were visually very similar to the results from the 2024 drill campaign; prompting Ultra to mobilize two additional drill rigs to site to expedite the drilling of an additional 20 holes (6,000 m) to complete the expanded drilling program by mid-to-January 2026,” Tom Drivas, CEO & Director of Appia, commented.

The new drillholes are planned to reach up to 300 metres with the main goal being to delineate the dimensions of the carbonatitic intrusion and confirm the continuity of the grades already identified in the previous program. All the new drillholes on the ULTRA Hard rock carbonatite Target intercepted only carbonatitic breccial similar to the ones already tested (Figure 1). Assay results are pending, and initial results are expected by the end of the year.
