HIGHLIGHTS Preliminary results from the final seven diamond drillholes (See July 9th and September 8th , 2026 news releases for other preliminary results) completed along the Mineralized RIB Corridor ("MRC") at the RIB North Discovery (Figure 1 & 2) - as part of the now concluded 2026 Angilak Exploration Program; 2026 drilling has now connected the RIB North and RIB East Discoveries, expanding the mineralized strike length from 1.45 km to 3.4 km, along the Eastern Limb of the MRC; Identification of a higher-grade, a thicker sub-zone of uranium mineralization proximal to RIBN-DD-001 was identified with drillholes found in Table 1. The sub-zone currently has an approximate 300 m strike length and 300 m down-dip extent intersecting similar thicknesses, apparent grades, and multiple stacked mineralized structures.
