Executive Summary

  • Ultra Rare Earth continues an expanded diamond drilling campaign on the ULTRA HARD ROCK carbonatite target, with 7 new drillholes (1,513.5 m) completed and all intercepting carbonatitic breccia.
  • Prior 2024 drill holes intercepted significant grades (e.g., 150 m @ 1.34% TREO, 0.13% Nb₂O₅). New holes aim to delineate intrusion dimensions; assay results are pending with expectations by year‑end.
  • Auger drilling on the ULTRA IAC target has completed 244 holes, with ongoing work in Taygeta, Merope and Gaia sectors; average grades remain consistent with earlier releases.

Key Details

  • Project Ownership: Appia holds a 25% interest in both ULTRA HARD ROCK and ULTRA IAC projects (total 42,932.24 ha) located in Goiás, Brazil. Ultra Rare Earth owns 50% and is the operator.
  • Diamond Drilling – ULTRA HARD ROCK
  • Campaign: 7,000 m total planned; three rigs deployed.
  • Completed: 7 new drillholes totaling 1,513.5 m, all intersecting carbonatite breccia to surface and extending to depth.
  • Historical intercepts (2024):
    • PCH‑DDH‑002: 150 m @ 1.34% TREO, 0.13% Nb₂O₅ from surface.
    • PCH‑DDH‑003: 147 m @ 2.00% TREO, 0.23% Nb₂O₅ from surface.
    • PCH‑DDH‑004: 153 m @ 1.32% TREO, 0.20% Nb₂O₅ from surface.
  • Carbonatite encountered at ~300 m true vertical depth; intrusion remains open in all directions.

  • Additional drilling planned: 20 holes (~6,000 m) to be completed by mid‑January 2026.

  • Auger Drilling – ULTRA IAC

  • Total auger holes completed: 244.
  • Sectors: Taygeta, Merope, Gaia (renamed ULTRA IAC target).
  • Current status: Expanding Taygeta sector; next phase will target Merope sector.

  • Grade summary (average) – see Table 1 in release (consistent with Jan 22 2025 press release).

  • Assay Results: All drill core samples from the new diamond holes are pending; initial assay data expected by end of 2025.

  • Operational Timeline: New drillholes targeted to reach up to 300 m depth; program completion anticipated early January 2026.

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‑January 2026.” – Tom Drivas, CEO & Director, Appia Rare Earths & Uranium Corp.
