Progress of Projects Including the Catalys Ridge Gold-Antimony Ore Mine in the US

Great Northern Minerals has delineated a 1-kilometer-long antimony ore vein at its Catalyst Ridge project in the US, with sampling results showing a grade of up to 7.1%. Old mining works were discovered during the operation.

This quartz-antimony ore vein shares a similar geological setting to Dateline Resource's nearby Colosseum deposit, indicating gold potential at depth.

The company has applied to expand the project area to 20.48 square kilometers.

PTR Minerals has completed resource delineation drilling at its Rosewood prospect in South Africa. Key intersections include:

◎ 31 meters at 13.5% heavy minerals from 8 meters depth, including a 10-meter interval grading 24.1% heavy minerals;

◎ 29 meters at 13.8% heavy minerals from 7 meters depth, including a 7-meter interval grading 29.7% heavy minerals.

The first resource estimate is expected by mid-2026.

PTR holds a 100% interest in Rosewood East and an 80% interest in Rosewood West, with the remaining 20% held by Narryer Company.
