Critical Metals (CRML) has begun a 10,000m diamond drilling programme at its fully owned Tanbreez Rare Earth Project in southern Greenland.
The company is carrying out the drilling as part of efforts to support resource growth, geological modelling, mine planning and future development at the project.

Recent weeks have seen the completion of essential accommodation and operational support infrastructure at the site.
This infrastructure is intended to support both the current drilling activity as well as ongoing work towards Tanbreez project development.
Contractors and support staff have arrived at the location, with drill rigs positioned across target areas following equipment inspections and readiness assessments.
Field teams will spend the next two to three weeks verifying ground conditions and marking out blast sites for planned access and development works.
This phase aims to confirm final drill collar locations, improve site access routes and help ensure the safe implementation of the drilling work.
Other ongoing tasks include geological mapping, surface verification, finalisation of drill pads and access routes, collar surveys, and environmental, health and safety monitoring.
The initial drilling is targeting key mineralised zones identified in earlier exploration and technical reviews.
Outcomes from these activities are expected to contribute to resource expansion, mine planning and infrastructure decisions.
Tanbreez is described by CRML as one of the largest undeveloped rare earth projects globally, with significant concentrations of heavy rare earth elements.
The company states that these elements are used in permanent magnets, electric vehicles, defence systems and advanced manufacturing.
Data generated from the 2026 drilling campaign is intended to underpin future resource updates, feasibility studies and other development works.
The programme is also expected to improve the company’s geological understanding of the project area.
CRML chairman Tony Sage said: “The start of our 10,000m drilling campaign marks another important step in the advancement of the world-class Tanbreez rare earth project. Following a successful mobilisation effort, drilling is now under way across priority target areas.
“The information generated from this programme is expected to support resource expansion, geological modelling, mine planning and other activities aimed at advancing Tanbreez toward production.”
In April this year, CRML signed a letter of intent to acquire all outstanding shares of European Lithium in a transaction valued at approximately $835m (A$1.19bn).
