U.S. and Australia Support for Nova’s Estelle Project

Strong support shown for the Estelle Project following meetings with Alaska State officials and site visit by the Australian Consular-General

Highlights

• Alaska State Governor, Mike Dunleavy (Figure 1) continues to show strong support for the Estelle Project in a meeting with Nova CEO Christopher Gerteisen, and reinforces the strategic alignment between its expansive resource base and district-scale potential, and Alaska’s key infrastructure development plans.

• Site visit by the Australian Consular-General, Tanya Bennett (Figure 3) recognizes the Estelle Project as a leading example of the deepening Australia–United States collaboration in critical minerals and strategic resource development.

• Builds on momentum from the recent Nova Board of Directors’ Alaska visit (ASX Announcement: 24 July 2025), where Alaska’s Congressional Delegation, including offices of U.S. Senators Lisa Murkowski and Dan Sullivan, Representatives Nick Begich and Kevin McCabe, and Matsu Borough Mayor Edna DeVries, all expressed broad support for Estelle’s development, and critical infrastructure such as the West Susitna Access Road and Port MacKenzie.

Nova CEO, Mr Christopher Gerteisen commented: “Momentum continues to build as the Estelle Gold and Critical Minerals Project gains significant strategic recognition. My recent meeting with Alaska Governor Mike Dunleavy confirmed that our long-term vision for Estelle is well aligned with the State’s infrastructure and economic development goals — particularly regarding the West Susitna Access Road, Port MacKenzie, and Alaska LNG. These initiatives, reinforced by recent U.S. Presidential Executive Orders, position Estelle as a potential key contributor to strengthening domestic resource security. With the February 2025 RFC Ambrian report naming Estelle as one of only nine global projects with near-term antimony production potential, alongside our rapidly expanding gold resource, we believe Estelle is emerging as a rare and valuable dual-commodity asset.

We are also encouraged by growing interest from the U.S. Department of Defense and the Australian Government. As an active member of the Defense Industrial Base Consortium, Nova is advancing applications for potential non-dilutive funding that could significantly accelerate development. While we’re not in a position to share full details just yet, the discussions underway extend far beyond traditional exploration support. Estelle is evolving from a single project into a strategic mineralized district — potentially critical to Western efforts to secure supply chains and reduce reliance on foreign sources of critical minerals. With all key elements now appearing to converge, we believe a major inflection point is approaching.”

Nova Minerals Limited ( Nova or Company ) ( ASX: NVA, NASDAQ: NVA, FRA: QM3 ) is pleased to provide an update where both Alaska State government officials and the Australian Consular-General have shown strong support for the Estelle Gold and Critical Minerals Project in recent meetings with Nova.

Meeting with Alaksa State Governor

Nova’s CEO, Christopher Gerteisen, was invited to meet with Alaska Governor Mike Dunleavy to discuss the Estelle Project’s progress and key infrastructure requirements (Figure 2) for it including:

• West Susitna Access Road – Alaska Industrial Development and Export Authority (AIDEA)supported infrastructure project which when completed will provide year round all weather road access to the Estelle Project. AIDEA, recently submitted a permit application for its 78.5 miles of proposed public and industry road (see AIDEA’s news release here) which will connect Estelle with existing road, rail, port, and energy infrastructure.

• Port MacKenzie Upgrade and Economic Zone - Enhancements to logistics and export capacity critical for scaling Estelle.

• Alaska LNG (AKLNG) - A vital energy infrastructure component to support mineral processing and sustainable project development.

Alaska Governor Mike Dunleavy has provided strong support for the West Susitna Access Road previously stating, “AIDEA’s West Susitna Road holds significant value for Alaskans, especially local residents seeking better access to hunting, fishing, recreation, and potential opportunities in mining, processing, and manufacturing. My administration and AIDEA are continually exploring ways to boost our economy and create well-paying jobs for families. This project presents a fantastic opportunity for Alaska to expand and generate revenue. I am dedicated to this initiative and to unlocking resources that will benefit all Alaskans.”

These initiatives are directly aligned with two pivotal Presidential Executive Orders , which prioritize domestic mineral supply chains and Alaska’s resource potential:

• Unleashing Alaska’s Extraordinary Resource Potential” (Jan 2025)

• Immediate Measures to Increase American Mineral Production” (Mar 2025)

Nova continues close collaboration with state and federal partners with a goal of fast-track permitting, infrastructure integration, and project development toward large-scale production.
