• Maiden JORC Mineral Resource Estimate (MRE) at Manyingee North of 9.8 Mlbs
• Upgraded MRE at Manyingee South of 14.9 Mlbs (previously 11.1 Mlbs)
• Total uranium resources at Yanrey now 55.6 Mlbs, a 32% increase

Cauldron Energy Limited (ASX: CXU) has announced a maiden Mineral Resource Estimate (MRE) for the Manyingee North deposit of 14.9 Mt @ 297 ppm eU3O8 for 9.8 Mlbs, as well as an upgraded MRE for the Manyingee South deposit of 21.2 Mt @ 319 ppm eU3O8 for 14.9 Mlbs. These new resources, which are entirely in the Inferred category, represent a 32% increase in Cauldron's total uranium resources at the Yanrey Project, now totaling 55.6 Mlbs. The Manyingee North deposit is located approximately 8 km northeast of the Manyingee South deposit and 2.5 km northeast of Paladin's Manyingee Deposit. Exploration drilling in 2025 discovered extensive uranium mineralization at Manyingee South, located about 2.5 km northeast of Paladin's Manyingee Deposit. The Manyingee South and Manyingee North deposits, as well as the surrounding regions, will be the focus of further exploration drilling in 2026 to expand Cauldron's defined uranium resources. The new MREs place the Yanrey Uranium Province among the world's larger uranium precincts, making it a globally significant uranium province.

The company has not provided any high-importance, price-sensitive forward-looking financial metrics or guidance.

Cauldron will focus on further exploration and resource expansion at the Manyingee South and Manyingee North deposits, as well as the Cosgrove prospect, during the 2026 drill program. The company has identified over 20 high-priority targets within its tenement holdings, each with the potential to host additional uranium mineralization.
