CRML Commences a 10,000 Meter Drilling Campaign at Tanbreez Rare Earth Project, Greenland

NEW YORK, June 17, 2026 (GLOBE NEWSWIRE) — Critical Metals Corp. (Nasdaq: CRML) (“Critical Metals Corp” or the “Company”), a leading critical minerals mining company, today announced the commencement of its planned 10,000-meter diamond drilling campaign at the Company’s wholly owned Tanbreez Rare Earth Project in Southern Greenland.

The drill program represents a significant milestone in the advancement of the Tanbreez Project and is designed to support resource expansion, geological modeling, mine planning, and future development activities across the project area.

Operational Progress and Mobilization Update

Over the past several weeks, the Company has made substantial progress in preparing for the 2026 field season. Construction and commissioning of the initial project infrastructure, including accommodation and operational support facilities, have been completed, supporting both the 2026 drilling program and the continued advancement of the Tanbreez Project toward development.

Drilling contractors and support teams have successfully mobilized to site, with drill rigs arriving and being positioned across priority target areas. Following the completion of equipment inspections, safety reviews, and operational readiness assessments, the Company’s 2026 diamond drilling program is now underway.

Tony Sage, Chairman of CRML, commented:

“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.”

Next Two to Three Weeks of Activity

Over the coming two to three weeks, field teams will focus on final ground verification activities and the completion of blast mark-outs associated with planned site access and development works. These activities are designed to validate drill collar locations, optimize access corridors and support the safe and efficient execution of the 2026 drilling program.

The Company will also continue:

• Advancing geological mapping and surface verification activities;
• Finalizing drill pads, access routes and supporting site infrastructure;
• Completing detailed collar surveys and positioning;
• Conducting ongoing environmental, health and safety monitoring programs;
• Expanding geological and technical data collection to support future resource updates, mine planning and project development activities.

Initial drilling will focus on priority mineralized zones identified through historical exploration, recent technical reviews, and geological modeling. The results of the program are expected to support resource expansion, mine planning, infrastructure design and other workstreams associated with advancing Tanbreez toward production.

Advancing a Strategic Rare Earth Asset

Tanbreez is one of the world’s largest undeveloped rare earth projects and contains significant concentrations of heavy rare earth elements that are critical to permanent magnets, electric vehicles, defense systems and advanced manufacturing technologies.

The 2026 drilling campaign is expected to generate important geological and engineering data that will support future resource updates, mine planning, feasibility studies and broader project development activities. The program will also further enhance the Company’s understanding of the mineralization and geological characteristics across the project area.

The Company expects to provide additional operational updates as drilling progresses and assay results become available.
