Work on the Tumas Project (Tumas) and associated off-site infrastructure continues to progress as planned and is on track for targeted first production in Q3 CY2027 (refer to Figure 1*).

HIGHLIGHTS Tumas Project

- Detailed engineering on the Tumas Project along with off-site power and water infrastructure finalisation is continuing to advance

- Focus continues on finalising detailed design for the process plant, completing the agreements for power and water supply and undertaking bulk earthworks at site

- Subsequent to quarter end, successful completion of a shallow reverse circulation drill program at the S-Bend prospect, which comprised of 452 holes for 3,361 m

o Drilling identified 4 clusters of higher-grade mineralisation worthy of follow-up drilling to increase the uranium resource base on the Tumas Project

o Best intersections include:

- SB0247: 8 m at 332 ppm eU3O8 from 1 m
- SB0560: 2 m at 1,217 ppm eU3O8 from surface

o 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

- Mini-pilot resin testwork on samples from the Ambassador and Princess deposits is successfully demonstrating recovery of uranium, base metals and rare earth elements

- Progress on the revised Definitive Feasibility Study entailing process engineering, capital and operating cost estimates, mining plan and schedules is being advanced

Alligator River Project

- Field work has been completed with results pending

- Reverse circulation and diamond drill program underway

Corporate

- Group cash balance on 30 September 2025 was A$203.5 million
