Nova Minerals Highlights Strategic Alignment with U.S. Defense Supply Chain Priorities Under White House Executive Order

Anchorage, Alaska, July 24, 2026 - Nova Minerals Corp (“Nova Minerals” or the “Company”) (NYSE American: NVA | ASX: NVA), a first mover currently developing a modern, fully integrated and secure U.S. domestic antimony supply chain spanning mining through to refining in Alaska, welcomes the Executive Order, ‘Securing America’s Defense Supply Chains and Ensuring Domestic Acquisition of Critical Materials’ (Executive Order), signed by U.S. President Donald J. Trump on July 20, 2026. The Company believes the Executive Order represents a significant policy milestone supporting the development of U.S. domestic critical minerals capacity and highlights the strategic relevance of its integrated antimony project.

The United States remains heavily reliant on imports for many critical minerals, including antimony, which is essential to the nation’s economic resilience and defence capabilities. The Executive Order reinforces the U.S. Government’s commitment to resilient domestic and allied critical mineral supply chains for defence by establishing a policy that military equipment and the critical materials required to manufacture, maintain and sustain it should be sourced from the United States or trusted allied nations. The Executive Order also mandates end-to-end supply chain traceability, including verification of raw material origin and assessment of foreign ownership and supply risks, while restricting materials sourced from entities linked to designated foreign adversaries. These measures will require defense contractors to rapidly qualify alternative U.S. domestic and allied suppliers, increasing demand for secure, compliant sources of critical minerals.

A Fully Secure Integrated U.S. Antimony Supply Chain

Nova Minerals is already building the kind of secure fully integrated U.S. domestic critical minerals supply chain the Executive Order is designed to encourage, with first antimony production from its pilot plant targeted for 2027. In October 2025, the Company was awarded a US$43.4 million Defense Production Act Title III award by the U.S. Department of War to support the development of an antimony mine at its Estelle Gold and Critical Minerals Project, and a downstream refinery at Port MacKenzie, both located in Alaska. Engineering and design for the Port MacKenzie pilot plant facility have been completed, with the scalable processing hub designed to treat concentrate from Estelle as well as potential third-party domestic and allied feedstocks. Process plant equipment procurement is underway, with key components delivered or in transit and construction expected to commence in the coming months. Upon completion, Port MacKenzie is expected to provide a strategic U.S. processing and toll-treatment capability, providing defense contractors with access to compliant military-grade antimony products and supporting a more secure and resilient U.S. domestic and allied supply chain.

Nova Minerals CEO, Mr. Christopher Gerteisen, commented:

“This Executive Order reflects the direction of U.S. policy on critical minerals sourcing that has informed our work at the Estelle Gold and Critical Minerals Project and our planned processing infrastructure at Port MacKenzie. It aligns directly with our vision to develop responsible, world-class mining and refining operations that contribute to U.S. resource security and national defense priorities. With the support of the U.S. Department of War, we remain focused on delivering a U.S. domestic antimony supply chain, targeting production in 2027.”
