Mineral Resource Estimate doubles contained scandium metal at Sunrise Energy Metals' Australian rare earths deposit

Upward revision to Estimate comes amidst reported supply shortages of rare earth elements

Feasibility Study to be completed later this month

Highlights:

• Measured and Indicated Mineral Resource materially increases following a step out drilling campaign at the Syerston Scandium Project, which now comprises: 
  • a global resource of 19,007 tonnes of contained scandium  (at a 300 g/t Sc cut-off) at an average grade of 414 g/t (a 98% increase in contained metal, with over 90% of the global resource now in Measured and Indicated categories); and
  • a high-grade resource of 1,155 tonnes of contained scandium (at a 600 g/t Sc cut-off) at an average grade of 665 g/t (a 161% increase in contained metal, with over 99% of the high-grade resource now in Measured and Indicated categories).
• Recent negotiations with scandium traders in North America indicate a significant tightening of scandium supply, and a marked increase in scandium prices since the imposition of China's export licensing restrictions on the metal in April 2025.
• The Syerston Feasibility Study is due for completion in late September and will support the Company's on-going discussions regarding financing and offtake.

MELBOURNE, Australia, Sept. 9, 2025 /PRNewswire/ -- Sunrise Energy Metals Limited ("Sunrise" or the "Company") (ASX:SRL; OTC:SREMF) Co-Chairman Robert Friedland, and Chief Executive Officer Sam Riggall, announce today an update to the Mineral Resource Estimate for the Syerston Scandium Project in NSW, Australia. 

Sunrise Energy Metals CEO, Sam Riggall, commented: "Global scandium supply remains tight since China's export controls were imposed in April 2025, positioning Syerston as a strategically important source for future scandium supply.  Our focus now turns to completing the Feasibility Study and evaluating various financing options for the Project."

Mr Friedland also commented: "The Syerston Scandium Project will bolster the supply of one of the most important rare earth metals at a time when supply disruptions are becoming the norm. The world we knew - built on globalized and integrated supply chains for strategic metals - is past, perhaps forever. Geopolitical competition over key technologies using these metals requires a complete rebuilding of the world's metal supply chains.  This is not just an industrial imperative.  It is an imperative that strives for a safer and more balanced approach to world affairs, one built on diversified and reliable supply chains stretching back to the mines that have, for millennia, produced the metals that are catalysts for human progress."
