Cauldron Energy Limited (ASX: CXU) has released the results of its 2026 passive seismic survey program conducted at its wholly-owned Yanrey Uranium Project in Western Australia. Cauldron Energy is an ASX-listed uranium-focused company that wholly owns the Yanrey Uranium Project, which covers approximately 1,493 square kilometers of mineral-rich territory in Western Australia. The recently completed survey, consisting of 29 lines for a total of 153.3 line km, was intended to build on previous geophysical work by accurately locating and extending the margins of the Meninge, Meninge South, Meninge North, and Cosgrove paleochannels to facilitate the initial schedule of Drill 20 and the start of 2000. 2027.
The survey yielded important insights in several areas. In Meningi South and Southeast, new data have confirmed a buried bedrock island and detailed the eastern arm of the Meningi South paleochannel, extending its top by at least three kilometres. Importantly, the previously suspected western tributary was defined, extending two kilometers upstream into a vast 2 x 2.5 km lake, now identified as a high priority exploration target. Similarly, surveys at Ashburton East have revealed the Ashburton Paleochannel leading to a strong lake before it reaches a steep incised gorge, a feature considered highly probable and similar to the Bennettwell East deposit.
Additionally, surveys at the Cosgrove Prospect described a distinct, smaller paleochannel, about 1.5 km wide and 3.5 km long. Recent exploration drilling at Cosgrove has already confirmed strong channel development, reaching a maximum depth of 125 metres. These latest geophysical results are being integrated with Cauldron’s 2025 passive seismic survey data, contributing to a more comprehensive understanding of the Yanrey region’s complex palaeochannel uranium system.
Cauldron Energy plans further air core or rotary mud exploration drilling through downhole geophysical surveys within the Yanrey Uranium Project to define new mineralization and expand existing mineral resource estimates. The company has been systematically exploring these palaeochannels as its finances allow, with newly identified high-priority targets expected to become the focus of incoming heritage approvals and subsequent drilling campaigns.
