• Drilling at RPM Valley confirms high-grade gold mineralization and resource growth potential
• Korbel Main deposit drilling defines higher-grade core zone for potential starter pit
• Surface sampling identifies new gold-copper anomalies across the Estelle corridor
• Progressing antimony production plans with equipment mobilization and winter road construction

Nova Minerals Limited (ASX: NVA) provided an update on its activities at the Estelle Gold and Critical Minerals Project in Alaska for the March 2026 quarter. Drilling at the RPM Valley target continued to demonstrate the scale and continuity of the gold mineralization, including a project-record intercept of 0.5m @ 364 g/t Au. These results support the potential for both large-scale bulk-tonnage mineralization and higher-grade zones within the broader RPM deposit. At the Korbel Main deposit, shallow RC drilling defined a higher-grade core zone with grades up to 1.2 g/t Au, highlighting the potential for a starter pit scenario. Surface sampling programs across the Estelle corridor identified several new gold and gold-copper anomalies, further demonstrating the district-scale potential of the project. Nova also advanced its plans to establish a U.S. domestic antimony supply chain, with successful winter road construction and equipment mobilization to the Estelle site. The company is fully funded to progress the antimony opportunity, with a US$43.4 million non-dilutive award from the U.S. Department of War. Ongoing Pre-Feasibility Study work is integrating these results to support the development pathways for Estelle's gold and antimony assets.

Nova Minerals is targeting the commencement of antimony production in late 2026 to early 2027, supported by a US$43.4 million funding award from the U.S. Department of War.

Nova Minerals is focused on integrating the latest exploration and development results into the ongoing Pre-Feasibility Study for the Estelle Gold Project, progressing the antimony production opportunity, and completing the planned redomiciliation to the United States to better align with its U.S. shareholder base and capital markets.
