Strategic positioning and market context

• Positioned as a U.S.-based supplier of critical magnet rare earth elements, supporting national security and industrial needs.

• U.S. law will ban Chinese-origin rare earth magnets in defense systems from January 2027, increasing domestic demand.

• China dominates global rare earth mining, refining, and magnet production, controlling over 90% of key supply chain stages.

• Export restrictions from China on key rare earths heighten the urgency for domestic supply.

Halleck Creek project highlights

• Halleck Creek in Wyoming is a world-class, multi-generational rare earth deposit with a JORC resource of 2.63 billion tonnes.
