Critical Metals Corp. (Nasdaq: CRML) announced the start of a 10,000-meter diamond drilling campaign at its wholly owned Tanbreez Rare Earth Project in southern Greenland, according to a company press release dated June 17, 2026.

The company said drilling contractors and support teams have mobilized to site, with drill rigs positioned across priority target areas. Initial drilling will focus on mineralized zones identified through historical exploration, recent technical reviews, and geological modeling.

Accommodation and operational support facilities have been completed ahead of the 2026 field season. Equipment inspections, safety reviews, and operational readiness assessments have also been completed.

Chairman Tony Sage said in a statement: "The start of our 10,000-meter drilling campaign marks another important step in the advancement of the world-class Tanbreez rare earth Project. Following a successful mobilization effort, drilling is now underway across priority target areas. The information generated from this program is expected to support resource expansion, geological modelling, mine planning and other activities aimed at advancing Tanbreez toward production."

Over the next two to three weeks, field teams plan to complete ground verification activities and blast mark-outs for site access. The company said it will also advance geological mapping, finalize drill pads and access routes, conduct collar surveys, and carry out environmental, health, and safety monitoring.

The company said drilling results are expected to support resource expansion, mine planning, feasibility studies, and infrastructure design. Critical Metals Corp. said it will provide additional updates as drilling progresses and assay results become available.
