Critical Metals Corp. (Nasdaq: CRML) has released final assay results from its 2025 drilling campaign at the Tanbreez Rare Earths Project in Greenland, reporting multiple extensions to known mineralisation and new high‑grade rare earth intervals across Area B and the Fjord Deposit.
The company said broad‑spaced drilling at Area B, located immediately east‑northeast of the Hill Zone, has outlined a 1.75km corridor of continuous rare earth mineralisation. Intervals from the 2025 programme returned TREO+Y grades typically ranging from 0.35% to 0.61%, with heavy rare earth oxides averaging approximately 25–27% of the total. Notable intercepts include 132m at 0.46% TREO+Y in hole 25‑D10 and 128m at 0.43% TREO+Y in hole 25‑D13, with strong concentrations of strategic metals such as gallium, hafnium, niobium, and cerium.
At the Fjord Deposit, new results from holes 25‑D14 and 25‑D15 confirmed mineralisation remains open along strike at the northeastern margin of the system. Intervals included 55.5m at 0.41% TREO+Y with 26% HREO. These results are expected to support updates to the Mineral Resource Estimate and future mine planning studies.
Tony Sage, CEO of Critical Metals Corp., commented, “I am very encouraged by the 2025 deep diamond drilling results, which continue to demonstrate meaningful extensions to our known Mineral Resource and confirm consistent rare earth mineralisation across the Fjord, Upper Fjord, Hill and now, Area B zone. These results enhance our confidence in the broader REE potential of the Tanbreez Deposit.”
He added that the latest assays are expected to contribute additional mineralised tonnage to the Hill and Fjord Deposits, supporting a potential uplift in scale for the larger Tanbreez footprint. The company plans to advance infill and extensional drilling during the 2026 field season, focusing on optimising future pit designs and progressing Mineral Resource studies.
Critical Metals noted that TREO+Y grades across both Area B and the Fjord system range from 0.35% to 0.77%, with consistent enrichment in high‑value heavy rare earths, underscoring Tanbreez’s position as a globally significant peralkaline‑hosted rare earth system. A detailed review of optimisation strategies for the 2026 season is currently underway.
