Industry Context

The Brook Mine project directly addresses the critical national need for a secure, domestic supply chain of rare earth elements (REEs) and critical minerals, particularly given the U.S.'s 100% reliance on imports for scandium, primarily from China. This initiative is strategically important for advanced technologies and national defense, aligning with government efforts to reduce foreign dependency. The project's unconventional deposit type, hosted in coal seams, offers a potentially more accessible, cost-effective, and environmentally responsible alternative to traditional hard-rock mining, which often faces challenges with elevated radioactive elements and lower recovery rates. The high 'basket price' of the Brook Mine's REE and critical mineral mix, significantly exceeding industry trends for similar TREO grades, positions it competitively against deposits dominated by lower-value elements like lanthanum and cerium.

Comparison to Industry Standards

• The Brook Mine distinguishes itself from traditional hard rock mining by potentially offering a more accessible, cost-effective, and environmentally responsible pathway to rare earth element (REE) recovery.
• Unlike hard rock deposits that are often accompanied by elevated radioactive elements, the Brook Mine's REEs are hosted in soft carbonaceous strata and coal seams with minimal radioactive content.
• Comparing the Brook Mine's basket price on an NdPr equivalent grade, it is more than 10X higher than the industry trend for its ppm TREO, indicating a superior value proposition.
• Typical higher ppm TREO deposits are often dominated by low-value lanthanum (La) and cerium (Ce) (70% to more than 80% La and Ce), which require significant cost to remove, a challenge less pronounced for the Brook Mine.
• Hard rock deposits often lose 35-45% of rare earths to tails prior to extraction, resulting in lower overall recoveries compared to the Brook Mine's expected flowsheet, which aims for higher recovered value per TREO grade.
• The Department of War's Defense Logistics Agency (DLA) signed an offtake to purchase scandium at over $6.2 million a ton, which is two-thirds higher than the $3.75 million level used in current economic modeling, highlighting a premium market valuation for this specific critical mineral compared to internal estimates and general market trends.
