Nova Minerals Secures Final Permits for Alaska Antimony Project, Clearing Path to 2027 Production

Anchorage, Alaska, October 27, 2026 – Nova Minerals Corp (“Nova Minerals” or the “Company”) (NYSE American: NVA | ASX: NVA) today announced it has received final approvals from the Alaska Department of Natural Resources for the Plan of Operations and Reclamation Plan for its Department of War funded Alaska antimony project, completing the Project’s permitting process and clearing the way for construction and development activities targeting production in 2027.

Highlights

• Final permits secured: Nova has secured all required permits within approximately three months of submission clearing the way for Phase 1 of its Alaska antimony development and advancing the establishment of the first modern, fully integrated U.S. domestic antimony supply chain in decades.

• Three-stage project approval from mining to refining: Permits cover stibnite mining at the Styx and Stibium prospects, ore sorting and processing at the Whiskey Bravo concentration site within the Estelle Project, and downstream processing and refining at Port Mackenzie.

• $43.4 million in Department of War funding: Phase 1 is fully funded through the Company’s existing award to support development of domestic production capacity for military-grade antimony trisulfide.

• Critical equipment delivered: All major long-lead and critical mining and processing equipment has been procured and delivered to project locations.

• Engineering and metallurgy completed: Process plant engineering and metallurgical test work have established a flowsheet designed to produce military-grade antimony trisulfide and standard grade II antimony metal (>99.65% Sb).

• Targeting 2027 production: With permitting complete, funding secured, engineering completed and equipment delivered, Nova is focused on advancing construction and executing its development schedule.

Nova Minerals CEO, Mr. Christopher Gerteisen, commented:

“Securing our final permits is a major milestone for Nova, moving our Alaska antimony project from development planning toward construction and targeted production in 2027.

“In a relatively short period, we have secured $43.4 million in Department of War funding, completed the permitting process, advanced engineering and metallurgical test work, and delivered critical equipment to our project locations.

“With these key milestones achieved, our focus is now on execution. We believe the Project has the potential to contribute to a more secure U.S. domestic antimony supply chain, while creating a meaningful new growth opportunity for Nova and our shareholders.”

From Permitting to Project Execution

The final approvals authorize construction and operating activities over an initial three-year term across the Project’s integrated development pathway. This includes stibnite mining at the Styx and Stibium prospects, intermediate-stage ore sorting and processing at the Whiskey Bravo concentration site within the Estelle Project, and downstream processing and refining at Port Mackenzie, Alaska.

The Company’s Phase 1 development program is supported by a $43.4 million award from the U.S. Department of War to advance domestic antimony production capacity. Metallurgical test work and process plant engineering have been completed, with the process flowsheet designed to support production of military-grade antimony trisulfide and standard grade II antimony metal (>99.65% Sb).

All major long-lead and critical mining and processing equipment has been procured and delivered to project sites, enabling Nova to accelerate construction and advance project development.

With final regulatory approvals secured and major development milestones already achieved, Nova is transitioning to the next phase of execution as it advances toward targeted antimony production in 2027.
