These results are in addition to the previously announced RIB North Discovery, where the maiden drillhole, RIBN-DD-001, returned assays with 34.7 m of total composite uranium mineralization1, including 13.6 m grading 0.53% U₃O₈, 1.1 m grading 4.81% U₃O₈, and grades up to 8.16% U₃O₈ over 0.5 m (See November 20th, 2025, RIB North Assay Release);RIB East DiscoveryLocated on the 4.5 km long Eastern Limb of the MRC, ~1.4 km south of the significant RIB North Discovery (Figures 2 & 3);Currently defined by eight diamond drillholes over a 750 m strike length that remains open in all directions, with drilling highlighted by:RIBE-DD-003 assays returned total composite uranium mineralization1 of 8.6 m encompassing four zones from 101.4 m to 374.1 m (Figure 4), including a high-grade intersection2 from 276.2 m to 277.3 m with 2.69% U3O8 over 1.1 m, including 5.55% U3O8 over 0.5 m;RIBE-DD-007 assays returned total composite uranium mineralization1 of 8.7 m encompassing six zones from 174.0 m to 215.3 m (Figure 5), including a higher-grade intersection from 207.2 m to 211.3 m with 0.236% U3O8 over 4.1 m, including 1.15% U3O8 over 0.5 m;RIB West DiscoveryLocated on the 4.0 km long Western Limb of the MRC, ~1.8 km southwest of the significant RIB North Discovery (Figures 2 & 3);Currently defined by three diamond drillholes over a 2.2 km strike length that remains open in all directions, with drilling highlighted by:RIBW-DD-001 assays returned total composite uranium mineralization1 of 1.7 m from 393.5 m to 395.2 m (Figure 6) with an average grade of 0.78% U3O8, including a high-grade intersection2 with 1.36% U3O8 over 0.6 m;RIBW-DD-003 assays returned total composite uranium mineralization1 of 2.0 m from 234.2 m to 236.2 m (Figure 7) with an average grade of 0.291% U3O8, including a high-grade intersection2 of 1.07% U3O8 over 0.5 m;RIB South Dis...
