Cauldron Energy Uncovers Expansive High-Grade Uranium at Manyingee North

Expanding Uranium Horizons at Manyingee North

Cauldron Energy Limited (ASX – CXU) has announced compelling new results from its Manyingee North prospect, part of the broader Yanrey Uranium Project in Western Australia. The recent drilling campaign, comprising seven additional air-core holes, has intersected broad zones of high-grade uranium mineralisation in all 12 holes drilled to date, confirming the prospect's potential as a significant new uranium discovery.

Located approximately 2.5 kilometres northeast of Paladin Energy’s Manyingee Deposit, Manyingee North lies within a largely unexplored extension of the Manyingee palaeochannel. The mineralisation extends from around 90 metres depth down towards bedrock, spanning over 800 metres in width and 700 metres along strike, with the deposit remaining open in all directions. This suggests a sizeable and continuous uranium system that could materially add to Cauldron’s resource base.

Context Within the Yanrey Uranium Province

The Yanrey Uranium Project covers approximately 1,340 square kilometres of highly prospective Cretaceous-age sedimentary basins, hosting multiple palaeochannels known to contain uranium mineralisation. Cauldron’s existing Mineral Resources at Yanrey exceed 40 million pounds of uranium oxide, anchored by the Bennet Well deposit (30.9 million pounds) and the recently defined Manyingee South deposit (11.1 million pounds).

Manyingee North’s discovery complements these assets and reinforces the Yanrey province’s status as a globally significant uranium province. The geological setting, characterised by sedimentary-hosted uranium deposits within palaeochannels, is analogous to other prolific uranium provinces, enhancing the prospectivity of Cauldron’s tenements.

Drilling Highlights and Technical Insights

The standout drill results include intercepts such as 4.80 metres at 1,016.5 ppm uranium oxide from 88.89 metres, and 2.79 metres at 710.9 ppm from 98.74 metres, demonstrating both thickness and grade that are encouraging for future resource development. The mineralisation is hosted within carbonaceous coarse sand units, although it lacks the typical bright yellow to orange oxidised sands seen at Manyingee South, indicating some geological variability within the palaeochannel system.

Cauldron’s CEO Jonathan Fisher expressed optimism about the results, highlighting the thick and high-grade nature of the mineralisation and the prospect’s open-ended potential. The company’s use of passive seismic and airborne electromagnetic surveys has been instrumental in identifying over twenty targets within the Yanrey Project, with Manyingee North now emerging as a key focus area.

Next Steps and Market Implications

Drilling is ongoing at Manyingee North, with a further ten holes planned to delineate the extent and continuity of the mineralisation. While a formal Mineral Resource Estimate for Manyingee North is yet to be completed, these results lay the groundwork for a potential resource upgrade in the near future.

Given the proximity to Paladin’s Manyingee Deposit, which contains an estimated 25.9 million pounds of uranium oxide, Cauldron’s discovery could enhance the strategic value of the Yanrey Project in the competitive uranium sector. Investors and analysts will be watching closely as Cauldron advances its exploration and moves towards resource definition and potential development pathways.
