DRILLING AT S-BEND PROSPECT CONFIRMS URANIUM EXTENSIONS

HIGHLIGHTS
• Successful Reverse Circulation drilling completed at the S-Bend prospect, with 452 drill holes
completed for 3,361 m
• The S-Bend prospect is located within the Exclusive Prospecting Licence 34G7 and situated
adjacent to the flagship Tumas Project on Mining Licence 237
• Drilling identified mineralisation with thicknesses up to 8 m from surface, with best
intersections including:
• SB0247: 8 m at 332 ppm eU3O8 from 1 m
• SB0560: 2 m at 1,217 ppm eU3O8 from surface
• SB0147: 5 m at 407 ppm eU3O8 from 1 m
• SB0156: 5 m at 367 ppm eU3O8 from 1 m
• SB0282: 4 m at 378 ppm eU3O8 from 1 m

• Higher-grade mineralisation identified at the S-Bend prospect is isolated to four main clusters,
with further detailed drilling required to delineate a resource base associated with these
clusters
• Importantly, potential to add to the Tumas resource and extend beyond the current 30-year Life
of Mine is further enhanced with discoveries being made such as the S-Bend prospect
