APPIA ANNOUNCES DRILLING UPDATES ON ULTRA HARD ROCK TARGET AND AUGER DRILLING ON ULTRA IAC TARGET IN GOIAS, BRAZIL

Ultra Rare Earth Inc. is continuing with the diamond drill program, announced by Appia Rare Earths & Uranium Corp. in its press release dated Oct. 22, 2025, on the high-grade zone on the project formerly known as the PCH project. Ultra acquired a 50-per-cent interest in the PCH project on Oct. 31, 2025 (see press release dated Nov. 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-per-cent interest in the Ultra Hardrock and Ultra IAC projects, which is 42,932.24 hectares in size and located within the state of Goias in Brazil.

Highlights

• Ultra Hard Rock -- 7,000 metres drilling campaign under way with three diamond drill rigs;
• Ultra Hard Rock -- seven new drill holes 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 drill holes of this campaign are an extension of the three drill holes PCH-DDH-002, PCH-DDH-003, PCH-DDH-004 executed in 2024 that intercepted 150 m at 1.34 per cent TREO (total rare-earth oxides), 0.13 per cent Nb2O5 from surface; 147 m at 2.00 per cent TREO, 0.23 per cent Nb2O5 from surface; 153 m at 1.32 per cent TREO, 0.20 per cent Nb2O5 from surface respectively (see press release dated March 10, 2025);
• Ultra Hard Rock -- carbonatite was intercepted at 300 metres true vertical depth and remains open at depth;
• Ultra IAC -- 244 auger drill holes completed.

Tom Drivas, chief executive officer and director of Appia, commented: "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-[late]-January, 2026."

The new drill holes 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 drill holes on the Ultra Hard Rock carbonatite target intercepted only carbonatitic breccial similar to the ones already tested. Assay results are pending, and initial results are expected by the end of the year.

Auger drilling on the IAC zones is progressing well with results on the Gaia sector showing similar grades and desorption characteristics to those found on the Merope and Taygeta sectors (Table 1). The auger drilling is now expanding the Taygeta sector and will be followed by auger drilling on the Merope sector. Assay results from the latest auger drilling on the Taygeta sector are pending.
