Critical Metals Corp.’s Releases First S-K 1300 Report on the Tanbreez 4.7 Billion Metric Ton Kakortokite Host Rock

Rhea-AI Summary

Critical Metals Corp (NASDAQ: CRML) has released its first S-K 1300 technical report for the Tanbreez Project, revealing a Maiden Mineral Resource Estimate of 45 million metric tons at 0.4% Total Rare Earth Oxides (TREO), including approximately 27% Heavy Rare Earth Elements. The deposit is hosted within 4.7 billion metric tons of kakortokite hard rock, making it the world's largest published rare earth hard rock deposit.

The company plans to begin its next phase of verification work in Q2 2025, including further resource drilling and an Independent Preliminary Economic Assessment (PEA). Critical Metals aims to complete its definitive feasibility study by year-end 2025. The initial MRE will be expanded upon through analysis of over 400 drill holes and 350,000 samples previously undertaken by Tanbreez Mining Greenland.

Positive

• World's largest published rare earth hard rock deposit with 4.7B metric tons of host rock

Negative

• Project still in early development phase requiring additional studies
• Several months needed before completion of definitive feasibility study
• Relatively low grade of 0.4% TREO

Insights

Mining Industry Analyst

Critical Metals Corp's release of its first S-K 1300 report marks a significant milestone in the development of the Tanbreez Project. The report confirms an initial Mineral Resource Estimate of 45 million metric tons at 0.4% Total Rare Earth Oxides, with a notable 27% consisting of Heavy Rare Earth Elements - typically the more valuable and scarcer rare earth components.

What makes this announcement particularly significant is the scale of the overall deposit - positioned within a massive 4.7 billion metric ton kakortokite host rock unit that the company describes as the world's largest published rare earth hard rock deposit. This suggests substantial potential for resource expansion beyond the initial estimate.

The company's accelerated timeline is ambitious but demonstrates confidence in the project's viability. Their plan to begin verification work in Q2 2025, followed by additional resource drilling and completion of a definitive feasibility study by year-end 2025, indicates an aggressive development strategy.

This independent verification represents a important de-risking step for Tanbreez. With over 400 drill holes and 350,000 samples already collected, the company has extensive data to support further resource definition. The commissioning of a Preliminary Economic Assessment in the coming quarter will be a critical next step in establishing project economics and development parameters.

As rare earth elements are essential for electrification and next-generation technologies, this resource could position Critical Metals as a significant Western supplier of these strategically important materials.

Maiden Mineral Resource Estimate of 45 million metric tons resource at 0.4% Total Rare Earth Oxides (“TREO”), including ~27% of Heavy Rare Earth Elements, hosted by the world’s largest currently published rare earth hard rock deposit

NEW YORK, March 12, 2025 (GLOBE NEWSWIRE) -- Critical Metals Corp. (Nasdaq: CRML) (“Critical Metals Corp” or the “Company”), a leading mining development company focused on critical metals and minerals and producing strategic products essential to electrification and next generation technologies for Europe and its western world partners, today announced that the Company has released its first S-K 1300 technical report summary (the “S-K 1300 Report”) on the Tanbreez Project, one of the largest rare earth deposits in the world hosted within - 4.7 billion metric tons of a kakortokite hard rock unit. The full S-K 1300 report can be viewed by visiting: https://www.criticalmetalscorp.com/projects/project-tanbreez. Agricola Mining Consultants Pty Ltd compiled the S-K 1300 Report.

“The release of our first S-K 1300 report for Tanbreez is a significant milestone for Critical Metals Corp as we are quickly advancing the development strategy for this game-changing rare earth deposit," said Tony Sage, CEO and Chairman of Critical Metals Corp. "The initial Mineral Resource Estimate (MRE) shows Tanbreez containing more than 45 million metric tons of resource of total rare earth and rare metal material, We now have independent verification of what makes this asset truly exceptional, and we believe that the S-K 1300 Report's findings will help accelerate our discussions with strategic partners and government agencies focused on establishing secure, western supply chains for these critical materials. We expect to begin our next phase of verification work in Q2 2025, with further resource drilling, an Independent Preliminary Economic Assessment (PEA) and end goal of completing our definitive feasibility study by year-end 2025."

Mr Sage also added:

“Due to the Company’s unique ownership structure, Critical Metals Corp must report all technical reports under the requirements set forth in Regulation S-K 1300 and the JORC Code as required by the U.S. Securities and Exchange Commission and ASX simultaneously. In the coming weeks this initial MRE is expected to be expanded upon by further analysis and announcements of the over 400 drill holes and 350,000 samples undertaken by Tanbreez Mining Greenland.

Due to the huge volumes of data already available, Critical Metals Corp has commissioned a PEA which is expected to be finalised and published in the next quarter.

The Company also intends to finalise the drilling results from the campaign that was completed late in 2024 and finalizing the 2025 exploration program.”
