Appia drilling Ultra Hard Rock, IAC targets in Brazil

Executive Summary

• Appia Rare Earths & Uranium Corp. reports ongoing drilling updates on its 25% interest in the Ultra Hard Rock and Ultra IAC targets in Goias, Brazil, operated by Ultra Rare Earth Inc.
• The Ultra Hard Rock diamond drilling campaign has completed 7 new holes (1,513.5 meters) intercepting carbonatite, with the program expanded to 7,000 meters using three rigs.
• Auger drilling on the Ultra IAC target has completed 244 holes, confirming expansion of ionic adsorption clay (IAC) rare-earth elements across the Taygeta, Merope, and Gaia sectors.

Key Details

• Ultra Hard Rock Project (Diamond Drilling):
  • Campaign size: 7,000 meters under way with three diamond drill rigs.
  • Progress: Seven new drill holes completed, totaling 1,513.5 meters.
  • Intercepts: All new holes intercepted carbonatite on their extensions; carbonatite intrusion remains open in all directions and at depth (intercepted at 300 meters true vertical depth).
  • Historical Context: Current holes are an extension of 2024 holes (PCH-DDH-002, 003, 004) which intercepted:
    • 150 m at 1.34% TREO, 0.13% Nb2O5 from surface.
    • 147 m at 2.00% TREO, 0.23% Nb2O5 from surface.
    • 153 m at 1.32% TREO, 0.20% Nb2O5 from surface.
  • Future Plan: Two additional rigs mobilized to expedite 20 more holes (6,000 m) to complete the expanded program by mid-to-late January 2026.
  • Objective: Delineate dimensions of the carbonatitic intrusion and confirm grade continuity.
  • Status: Assay results pending; initial results expected by end of year.
• Ultra IAC Project (Auger Drilling):
  • Progress: 244 auger drill holes completed.
  • Targets: Taygeta, Merope, and Gaia sectors (formerly Taygeta, Merope, and Gaia targets).
  • Results: Gaia sector shows similar grades and desorption characteristics to Merope and Taygeta sectors.
  • Future Plan: Auger drilling expanding the Taygeta sector, followed by the Merope sector.
  • Status: Assay results from latest Taygeta sector drilling are pending.
• Project Ownership & Location:
  • Appia holds a 25% interest in the Ultra Hardrock and Ultra IAC projects.
  • Total project size: 42,932.24 hectares.
  • Location: State of Goias, Brazil.
  • Operator: Ultra Rare Earth Inc. (acquired 50% interest in the PCH project on Oct 31, 2025).

Notable Quotes

• "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." — Tom Drivas, CEO and Director of Appia
