Results further expand Mineralisation at Manyingee South

• Drilling results extend mineralization ~650m southwest, ~600m east, and ~1,000m southeast
• Significant high-grade intersections up to 750.8 ppm eU3O8 over 1.78m
• Mineralization remains open in multiple directions with potential for resource expansion

Cauldron Energy has received results for an additional 23 drillholes (25YRAC011 to 25YRAC033) completed at the Manyingee South deposit within its Yanrey Uranium Project. The results have extended the known mineralization significantly, with the deposit now defined over a 650m southwest, 600m east, and 1,000m southeast of the previous drilling. Significant high-grade intersections were encountered, including 1.78m at 750.8 ppm eU3O8, 4.17m at 313.6 ppm eU3O8, and 2.79m at 537.1 ppm eU3O8. The drilling has demonstrated that the Manyingee South palaeochannel is more substantial than initially interpreted, with the mineralization remaining open in multiple directions. The company plans to continue drilling at Manyingee South as well as testing the high-priority Manyingee North prospect, with the aim of further expanding the resource during 2026.

Cauldron plans to continue drilling at Manyingee South to further expand the known mineralization, as well as test the high-priority Manyingee North prospect. The company expects to update the resource model for Manyingee South during Q1 2026 once the full drill program is completed.
