Slide 11: Oban Uranium Deposit
Oban Uranium Deposit Initial drilling confirms shallow, high-grade mineralisation Potential to expand the resource base through step out drilling and discovery. • Significant results from Koba’s maiden drill program in 2024 include: • 3.9m @ 805ppm eU3O8 from 87.0m; including • 1.3m @ 1,261ppm eU3O8
Slide 12: Oban Uranium Deposit: Significant results from previous drilling
Oban Uranium Deposit Significant results from previous drilling Consistent and contiguous high- grade mineralisation. • Contiguous drill results from a single section include: • 2.12m @ 2,236ppm eU3O8; • 2.65m @ 1,174ppm eU3O8; 2.12m @ 2,236ppm eU3O8 • 2.20m @ 1,502ppm eU3O8; and • 1.80m @ 1,306ppm

Berber and Chivas Prospects High-grade uranium discoveries from step out exploration drilling Strong potential for resource expansion confirmed by these discoveries. • High-grade results from new discoveries include: • the Berber Prospect. • 1.6m @ 1,026ppm eU3O8 from 91.5m. • The Chivas Prospect. •
Slide 14: Berber Prospect
Berber Prospect High-grade results - open in all directions Sparsely drilled 1500m corridor between Berber and the Oban Deposit. • Berber was first identified in the 1990s when ten holes were drilled. • Koba has discovered thicker and higher-grade mineralisation >350m further east, with significant
Slide 15: Chivas Prospect
Chivas Prospect High-grade mineralisation remains open to the east Discovered with step out drilling 700m east of the Oban Deposit. • Significant uranium mineralisation identified in the initial step out drilling at the Chivas Prospect, 700m east of the Oban Deposit including: • 1.0m @ 629ppm eU3O8
Slide 16: Significant Regional Potential
Significant Regional Potential 250km of palaeochannels to explore across 5,000km2 Numerous prospects to follow-up. • Previously identified prospects with limited and only broad-spaced drilling that have returned significant intercepts include: • Yarramba North – 2.0m @ 530ppm eU3O8. • Bingelly – 1.0

Slide 23: In-Situ Recovery (ISR)
In-Situ Recovery (ISR) Accounts for ~ 60% of global uranium production • Discoveries within the Yarramba Project will potentially be amenable to ISR mining like the neighbouring Honeymoon Mine. • Well understood and proven technology. • Low-cost mining method. • Reverses the natural process of urani
Slide 24: Nuclear Energy is a Clean Energy Source
Nuclear Energy is a Clean Energy Source Uranium spot price has gained 200% Uranium Spot Price $US/lb over 5 years, despite recent pullback As at 1 May 2025 $120 • Nuclear energy, using uranium as fuel, helps fight climate change by providing low-carbon power as an alternative to $100 fossil fuels. •
Slide 25: Growth in Nuclear Energy is driving increased demand for uranium
Growth in Nuclear Energy is driving increased demand for uranium Nuclear is a well-established industry with a supply demand gap • Approximately 440 nuclear reactors operate globally. • Countries are turning back to “clean” nuclear power with: • 60 nuclear reactors under construction; and • 110 nucl
