Cauldron Energy has intersected uranium mineralisation over a strike length of approximately 2,500 metres upstream beyond existing resource polygon limits at the Manyingee South deposit within its Yanrey project in Western Australia.

Assay results from 19 drillholes at Manyingee South returned notable intercepts, including drill hole 26YRAC064, which returned 4.56 metres at 346.3 ppm eU3O8 from 75.16 metres. Drill hole 26YRAC065 intersected 1.74 metres at 276.8 ppm eU3O8 from 75.7 metres and 2.46 metres at 234.7 ppm eU3O8 from 77.54 metres, while drill hole 26YRAC055 yielded 1.74 metres at 454.1 ppm eU3O8 from 66.18 metres.

Infill drilling at the D roll-front zone encountered well-developed mineralisation downstream of the closure, extending the high-grade zone approximately 200 metres north and 300 metres west. Results from a further 21 drillholes at Manyingee North also demonstrated continuous mineralisation extending north for several kilometres, though drilling in that area has reached the limit of current heritage clearance.

Cauldron has defined in excess of 55 million pounds of uranium oxide in Mineral Resources across three separate deposits at Yanrey, comprising Bennet Well, Manyingee South, and Manyingee North.

To facilitate further drilling at both Manyingee South and Manyingee North, the company has recently undertaken a second heritage clearance this calendar year, alongside testing new targets identified by a recently completed passive seismic survey.

The 2026 drill program continues to be highly productive. We have moved on from expanding mineralisation at Manyingee North, where we have reached the limit of our existing heritage clearance, to expanding mineralisation at Manyingee South, with these latest results demonstrating that the mineralisation extends ~2.5 kms upstream, which is clearly a fabulous result.

Our focus is on maximising the size potential of our MRE polygons (subject to independent confirmation) at Manyingee North and Manyingee South before we test potential new discovery areas. We look forward to publishing MRE updates for each of Manyingee North and Manyingee South in due course.

Cauldron Energy plans to publish Mineral Resource Estimate updates for the Manyingee North and Manyingee South deposits.
