Appia Reports Diamond Drilling on ULTRA HARD ROCK Carbonatite Target Intercepts 300m at 2.55% Total Rare Earth Oxide from Surface Including 1.7m at 14.27% TREO in Goias, Brazil
API · Price
Executive Summary
- Ultra Rare Earth completed a 26‑hole, 7,347 m diamond drilling program on the Ultra Hard Rock carbonatite target in Goiás, Brazil.
- Preliminary assays from 13 holes show multiple high‑grade intervals, including a standout 1.7 m intercept grading 14.27 % TREO at 95.3 m depth.
- Results confirm extensive carbonatite intrusion dimensions, low uranium/thorium levels, and support the upcoming mineral resource estimate for the Hard Rock project.
Key Details
- Total drilling: 26 holes, 7,347.1 m total length.
- Appia holds a 25 % interest in the Ultra Hard Rock and Ultra IAC Projects (42,932 ha).

- Magnet Rare Earth Oxides (MREO) are expressed as the sum of Nd₄O₇, Pr₂O₃, TbO₁₁, and Dy₂O₃.
- Uranium and thorium concentrations are low: 7.46 ppm U and 66.48 ppm Th on average.
- Drilling reached depths up to 300 m, delineating most of the carbonatitic intrusion and confirming continuity of grades identified in prior work.
- Ongoing work: two RC rigs currently drilling the Ultra IAC target; two additional rigs expected early March for a total plan of 952 RC holes. Initial IAC assay results due in coming weeks. Two auger rigs also operating.
Quality Assurance / Quality Control
- Core split at 2 m intervals, ~4‑5 kg per sample; half retained for future testing.
- Samples processed by ALS laboratory (Goiânia) and final analysis in Lima, Peru using ME‑MS81h (ICP‑MS) for REE and ME‑ICP06h (ICP‑AES) for major oxides.
- QA/QC includes blanks, duplicates, standards (minimum 3 standards, 1 duplicate, 1 blank per batch).
Notable Quotes
Tom Drivas, CEO & Director, Appia Rare Earths & Uranium Corp.:
“These latest drill results continue to demonstrate the impressive scale and grade of the Ultra Hard Rock carbonatite mineralized system… particularly notable is the exceptional high‑grade interval of 1.7 m grading 14.27 % TREO at 95.3 m, which highlights the strength of the system.”
