Cauldron Energy Uncovers Thick High-Grade Uranium at Manyingee North Prospect

A New Chapter in Uranium Exploration

Cauldron Energy Limited has revealed a promising new uranium discovery at the Manyingee North prospect, part of its expansive Yanrey Uranium Project in Western Australia. The initial results from five air-core drillholes have intersected broad zones of uranium mineralisation, with some intervals exhibiting notably high grades. This discovery not only adds to Cauldron’s growing resource base but also positions the company alongside established players like Paladin Energy, whose Manyingee Deposit lies just 2.5 kilometres to the southwest.

Significant Drilling Results and Geological Context

The drilling campaign at Manyingee North has returned encouraging results, with mineralisation starting from around 90 metres depth and extending downwards towards bedrock. The mineralised zone spans over 600 metres in width along the initial drill line and extends a further 250 metres southwards, with mineralisation remaining open in all directions. Noteworthy intercepts include a 2.72-metre section grading 887.2 parts per million uranium oxide equivalent (eU3O8) and multiple other intervals exceeding 150 ppm eU3O8 over significant thicknesses.

Geologically, the mineralisation is hosted within a largely unexplored northeast-trending extension of the Manyingee palaeochannel system. This sedimentary environment is known for hosting roll-front style uranium deposits, similar in character to the adjacent Manyingee Deposit owned by Paladin Energy. The discovery at Manyingee North thus reinforces the prospectivity of the Yanrey Uranium Province, which stretches over 80 kilometres and contains multiple palaeochannels with uranium potential.

Advanced Exploration Techniques Driving Success

Cauldron’s exploration methodology, which integrates passive seismic surveys and airborne electromagnetic (EM) surveying, has been instrumental in pinpointing these mineralised zones. According to Exploration Manager John Higgins, this approach has proven effective in the past 18 months, leading to two new discoveries including Manyingee North. The company’s ability to interpret geophysical data and target drilling accordingly highlights the underexplored nature of the Yanrey Uranium Province and its potential for further resource growth.

Resource Base and Future Plans

Cauldron’s Yanrey Project already boasts a substantial uranium inventory, with over 40 million pounds of uranium oxide defined across its Bennet Well and Manyingee South deposits. Bennet Well alone contains nearly 31 million pounds of uranium oxide, while Manyingee South adds over 11 million pounds. The new discovery at Manyingee North promises to augment this resource base significantly.

The company plans to continue its 2025 drilling program with up to 18 holes targeted at Manyingee North, alongside ongoing drilling at Manyingee South. Additionally, diamond core drilling is scheduled for 2026 to further delineate the mineralisation and support resource estimation. These efforts aim to better define the extent and grade continuity of the uranium mineralisation, potentially enhancing the project’s economic prospects.

Strategic Positioning in a Growing Market

With global interest in uranium rising amid the energy transition and nuclear power’s role in low-carbon electricity generation, discoveries like Manyingee North are timely. Cauldron’s expanding footprint in the Yanrey Uranium Province, combined with its proven exploration techniques, positions it well to capitalize on this market momentum. The proximity to Paladin’s established deposit also offers potential synergies and comparative benchmarks for development.
