Highlights

Cauldron completed 100 air-core drill holes totalling 10,506 metres at Yanrey during 2026.
The company reported 55.6 million pounds of uranium oxide in Yanrey Mineral Resources.
Cash at 30 September 2026 was AUD 2.43 million, with an updated Mineral Resource assessment underway.
Cauldron Energy (ASX:CXU) closed at AUD 0.056 on 5 November 2026, rising 12.00%.

Cauldron Energy Limited (ASX:CXU) is a mineral exploration company focused on uranium, particularly its Yanrey project in Western Australia. During 2026, the company completed an extensive air-core drilling campaign across the project and began assessing how new results could change its reported Mineral Resources. Cauldron Energy (ASX:CXU) closed at AUD 0.056 on 5 November 2026, a gain of 12.00% during the session. Its exploration findings and funding position should be considered independently of that one-day market movement.

Yanrey Project and Reported Resources

Yanrey includes the Bennet Well, Manyingee South and Manyingee North uranium deposits. A February 2026 resource update added a maiden estimate for Manyingee North and revised the estimate for Manyingee South. The company reported a combined 55.6 million pounds of uranium oxide in Mineral Resources across the three deposits. The reported categories, estimation assumptions and cut-off grades determine how those quantities should be interpreted. Inferred resources have a lower level of geological confidence than measured or indicated resources, and are not equivalent to reserves. Cauldron Energy (ASX:CXU) also controls exploration areas where drilling has not yet demonstrated sufficient geological evidence for inclusion in a Mineral Resource.

Results from the 2026 Drilling Program

The company’s October 2026 Quarterly Report recorded 100 air-core holes covering 10,506 metres over a 76-day campaign. At Manyingee North, reported mineralisation extended approximately 2,500 metres north and 550 metres south of the previously delineated area. At Manyingee South, drilling traced mineralisation approximately 2,500 metres farther upstream. These extensions concern the location and continuity of mineralisation, not a quantified addition to the resource estimate. Cauldron Energy (ASX:CXU) initiated modelling to incorporate the new results into a revised JORC Mineral Resource statement. The company also used passive seismic data to interpret buried palaeochannel systems and target drilling. Geological interpretation, assay or radiometric validation and resource modelling must be completed before a revised quantity can be stated reliably.

Cash Position and Project Expenditure

Cauldron reported AUD 2.43 million cash as at 30 September 2026, compared with approximately AUD 3.68 million at the end of June. The quarterly cash-flow report recorded AUD 1.25 million of net cash used in operating activities, including AUD 845,000 on exploration and evaluation. The company disclosed an estimated 1.94 quarters of funding based on the Appendix 5B calculation, while noting that the completed drilling program could reduce near-term outgoings. Cauldron Energy (ASX:CXU) may nevertheless need further Capital for future exploration and studies. The difference between a project’s geological scale and the cash needed to progress it is material for an exploration Business without producing uranium operations.

Regulatory Conditions and Project Relationships

Western Australia’s prohibition on uranium Mining remains a critical constraint on any eventual development of the Yanrey deposits. Exploration results cannot remove that policy barrier or establish a development timetable. Cauldron also reported a technical visit to Yanrey by representatives of organisations from Uzbekistan in October 2026. The visit related to cooperation and technical assessment, but should not be confused with a binding development or financing agreement. For Cauldron Energy (ASX:CXU), further developments to monitor include the revised Mineral Resource estimate, proposed drilling or study programs, cash funding arrangements and any material change in the regulatory framework. Uranium market conditions are relevant, but commercial assumptions require a project-specific assessment.

Key Insights

Cauldron Energy (ASX:CXU) completed its 2026 Yanrey drilling program and documented extensions to mineralised areas at Manyingee North and South. The updated resource assessment will determine whether those results change the reported inventory. Cash availability and Western Australia’s uranium policy remain important constraints alongside exploration progress.
