The high grade paleo-channel is situated over an area measuring 1.6km long and 120m wide identified following the recent drilling program at the Bennet Well east area.
All of the holes drilled to date at the Yanrey project had intersected uranium, with 11 of 15 holes intersecting high grade ore.
Results from drilling reported 3,706ppm eU3O8 and 2156 ppm eU3O8.
The drilling will also test for potential extensions to the Bennet Well deposit and explore other identified palaeochannels within the project.
Cauldron operations head Simon Youds said the results emphasize that the new high grade paleo-channel is significant in terms of its grade and its length.
"To be clear, this is a new discovery of a high grade uranium channel that extends for some kilometres, all within Cauldron tenements, and one that has everyone involved in the company genuinely excited," he added.
According to the company, the area hosts over 90km² of untested target areas with favorable uranium mineralization.
