Resource Growth Hinges on Further Drilling as Manyingee South Remains Open
Cauldron Energy’s 2025 drilling campaign at Manyingee South has intersected significant high-grade uranium mineralisation, expanding the deposit’s footprint and reinforcing the Yanrey Project’s potential amid rising global uranium demand.
- First 10 drill holes confirm and extend high-grade uranium mineralisation
- Deposit expanded by 200m in width and 150m in length, defining a crescent-shaped zone
- Eight of ten holes exceed 150ppm uranium oxide cut-off grade
- Mineralisation remains open to the south and southeast for further expansion
- Efficient drilling operations improve cost-effectiveness and data turnaround
Strong Start to 2025 Drilling Campaign
Cauldron Energy Limited (ASX, CXU) has announced promising initial results from its 2025 drilling campaign at the Manyingee South uranium deposit, part of the broader Yanrey Uranium Project in Western Australia. The first 10 air-core drill holes have intersected high-grade uranium mineralisation, extending the known deposit by approximately 200 metres in width and 150 metres in length. This expansion defines a distinctive crescent-shaped high-grade zone associated with the lower “D” roll-front, a key geological feature indicative of uranium accumulation.
Expanding the Mineralised Footprint
The drilling results reveal that eight out of the ten holes returned uranium concentrations above the 150ppm eU3O8 cut-off grade, underscoring the robustness of the mineralised system. Notably, drill hole 25YRAC005 recorded an impressive 1.52 metres at 2,766.8ppm eU3O8, while 25YRAC010 intersected 5.04 metres at 827.9ppm eU3O8. These grades are consistent with roll-front style uranium deposits, similar to the adjacent Manyingee deposit owned by Paladin Energy, which is known for its high-grade uranium mineralisation.
Strategic Location and Project Scale
The Yanrey Uranium Project spans over 80 kilometres of ancient sedimentary coastline, hosting multiple palaeochannels prospective for uranium mineralisation. The Manyingee South channel, where the current drilling is focused, is one of more than 20 identified palaeochannels within Cauldron’s tenement area. The project already boasts a combined Mineral Resource exceeding 40 million pounds of uranium oxide, with the Bennet Well deposit contributing 30.9 million pounds and Manyingee South adding 11.1 million pounds.
Operational Efficiency and Future Plans
Cauldron’s CEO Jonathan Fisher highlighted the operational improvements in the current campaign, noting that changes implemented have increased drilling metres per shift, enabling faster and more cost-effective access to results. The high-grade zone remains open to the south and southeast, with ongoing drilling planned to further delineate the deposit. Additionally, Cauldron intends to commence drilling at the high-priority Manyingee North prospect in the coming weeks, aiming to unlock further uranium potential within the Yanrey Project.
Context Amid Global Uranium Demand
These exploration advances come at a time when the global nuclear energy sector is experiencing renewed interest, driven by concerns over energy security and decarbonisation. The anticipated tightening of uranium supply underpins the strategic importance of discoveries like Manyingee South. Cauldron’s expanding resource base positions it well to benefit from this market dynamic, though further drilling and resource updates will be critical to fully realise the project’s value.
Bottom Line?
As Cauldron pushes its drilling further south and southeast, the Manyingee South deposit could become a cornerstone asset in Australia’s uranium resurgence.
Questions in the middle?
- How will upcoming drilling at Manyingee North influence the overall resource potential?
- What are the timelines and plans for advancing from exploration to development?
- How might evolving uranium market conditions impact Cauldron’s project financing and partnerships?
