Critical Metals Corp Reports Extremely High-Grade Drilling Results From its 2024 Program: 103 PPM Gallium & rare earth elements of 27.0% HREO & TREO Range 0.48% to 0.55% & Zirconium Oxide of 1.99% From Tanbreez in Greenland

  • Superior drilling results continue to exceed the Company’s expectations and are expanding Tanbreez at vast scale and build upon very successful past Tanbreez drilling results.
  • Consistent uniformity across the deposits intersecting ultra high-grade rare earth element mineralisation intersected in all four reported holes, with total rare earth oxide (TREO) grades between 0.48% and 0.55%.
  • High proportion of heavy rare earth oxides (HREO) 27.0% of HREO, reinforcing the deposit’s strategic value.
  • Significant zirconium oxide (ZrO₂) grades of 1.86–1.99% across all holes.
  • Gallium oxide (Ga₂O₃) assays between 90–100 ppm, providing a potential additional economic credit.
  • All holes drilled vertically (-90°) through sub horizontal, stratiform kakortokite layers, intersecting mineralisation at approximately true thicknesses.
  • Mineralisation remains open at depth in all reported holes.
  • Drilling confirms continuity of grade and mineralogy across multiple sections of the Fjord Deposit, consistent with historical data.
  • The holes are part of the ongoing 2024–2025 Fjord Resource Upgrade program, with over 1,500 m drilled to date in 2025 and further assays pending (due late Aug–Oct 2025).

NEW YORK, Aug. 18, 2025 (GLOBE NEWSWIRE) — Critical Metals Corp. (NASDAQ:CRML) (“Critical Metals Corp” or the “Company”), a leading critical minerals mining company, is pleased to publish the assay results from the Tanbreez Project in Greenland from its 2024 drilling program.
