• Drill results include the highest-grade intercept drilled at RPM - and over the greater Estelle Project - to date of 0.5m @ 364 g/t Au
• Broad gold intersections continue at RPM Valley with the 2025 closely spaced infill results expected to support a maiden Measured and Indicated Mineral Resource
• Mineralization remains wide open with numerous holes extending below the current pit shells

Nova Minerals Ltd announced further drill results from the RPM Valley deposit within its flagship Estelle Gold and Critical Minerals Project in Alaska. The 2025 closely spaced infill drilling returned multiple broad intercepts greater than 1 g/t Au, with visible gold observed, including the highest-grade intercept drilled at RPM - and over the greater Estelle Project - to date of 0.5m @ 364 g/t Au. The new results confirm the continuity of mineralization at RPM Valley, where previous drilling had also returned significant intersections. The drilling is expected to support a maiden Measured and Indicated Mineral Resource at the valley deposit, in support of the Pre-Feasibility Study. Mineralization remains wide open with numerous holes extending below the current pit shells. Highlights include 65m @ 3.6 g/t Au, 155m @ 0.9 g/t Au, 172m @ 0.8 g/t Au, and 289m @ 0.7 g/t Au. The company also completed 10 reverse circulation holes in the RPM glacial till, returning a notable intercept of 33m @ 0.3 g/t Au from surface, indicating the till material may be at least 30m thick over a large area and remain a high-priority target. Pre-feasibility level studies are ongoing, including additional metallurgical test work, mining studies, and optimization.

Nova remains focused on advancing RPM toward development while continuing to grow the resource base. With a number of near-term milestones ahead and a strong pipeline of exploration targets across the broader project area, RPM Valley continues to demonstrate its potential as a key growth asset for the company.
