Anchorage Alaska, Oct. 14, 2025 (GLOBE NEWSWIRE) -- Nova Minerals Limited ("Nova" or the "Company") (NASDAQ:NVA) (ASX: NVA) (FRA: QM3) ) is pleased to announce that it has been approached by His Excellency The Hon Dr Kevin Rudd AC, Australian Ambassador to the United States, to provide a comprehensive update on its Estelle Gold and Critical Minerals Project in Alaska. This briefing is in preparation for the upcoming meeting between Australian Prime Minister Anthony Albanese and U.S. President Donald Trump, scheduled for Thursday, October 20, 2025, in Washington DC, where critical minerals and strategic resource cooperation will be key discussion points.

Highlights

Nova has been requested by His Excellency The Hon Dr Kevin Rudd AC, Australian Ambassador to the United States, to provide a briefing on its Estelle Gold and Critical Minerals Project ahead of the meeting between Australian Prime Minister Anthony Albanese and U.S. President Donald Trump on October 20, 2025 in Washington DC.
The briefing follows a site visit by the Australian Consular-General, Tanya Bennett in August this year which recognized the Estelle Project as a leading example of the deepening Australia–United States collaboration in critical minerals and strategic resource development.
Recent US$43.4 million award from the U.S. Department of War (DoW) and robust government backing at federal, state and local levels, highlights the strategic importance of Nova's antimony production plans, targeting military-spec antimony by 2026/27.
Nova's planned antimony refinery at Port MacKenzie, with secured land use permits, further strengthens its position as the leading emerging fully integrated antimony producer in the U.S.
The inclusion of antimony on the U.S. Critical Minerals List, coupled with growing global demand, underscores the Estelle Project's strategic importance in supporting U.S. defense and industrial supply chains.

Nova CEO, Mr Christopher Gerteisen, commented: "Being invited to brief the Australian Government for this high-level meeting between Prime Minister Albanese and President Trump is a testament to the strategic importance of the Estelle Project. With antimony recognized as a critical mineral and our gold resources adding significant value, Nova is well-positioned to contribute to both U.S. and Australian critical minerals strategies. The US$43.4 million DoW award and our secured land at Port MacKenzie underscore our commitment to building a secure, domestic supply chain for antimony and supporting U.S. defense and industrial needs. We look forward to continued collaboration with both governments as we advance the Estelle Project toward production."

Strategic Engagement with Australian and U.S. Governments

As part of the briefing, Nova has been requested to provide details on its U.S. investments, including an overview of the Estelle Project, the key minerals identified, planned expansion activities, and the Company's engagement with U.S. government agencies. This request highlights the growing strategic importance of the Estelle Project, located in Alaska's prolific Tintina Gold Belt, which hosts significant gold and antimony assets. The Project's antimony prospects are of particular significance given antimony's recent inclusion on the U.S. Department of the Interior's Draft 2025 Critical Minerals List and its vital role in the defense, energy, and advanced manufacturing sectors.

Nova's recent US$43.4 million award from the U.S. Department of War (DoW) to its wholly-owned subsidiary, Alaska Range Resources LLC, further validates the project's importance. The funding supports the accelerated development of a fully integrated U.S. antimony supply chain, targeting production of military-spec antimony by 2026/27. Additionally, Nova's secured land use permit for a proposed antimony refinery at Port MacKenzie positions the Company as a first-mover in establishing a domestic antimony production hub.

Estelle Project Overview

The Estelle Project, spans 514 km² of State of Alaska mining claims, located 150 km northwest of Anchorage in the Tintina Gold Belt. The project contains one of the world's largest undeveloped gold deposits with over 20 advanced gold and antimony prospects across a 35 km long mineralized corridor, including two defined multi-million ounce gold resources and several drill-ready antimony prospects with significant outcropping stibnite vein systems.

The project's potential is further enhanced by its proximity to world-class infrastructure and its alignment with regional development initiatives, such as the West Susitna Access Road. Nova's proposed antimony refinery at Port MacKenzie, supported by a 42.81-acre land use permit, will produce a range of antimony products, including antimony trisulfide (Sb₂S₃), antimony trioxide (Sb₂O₃), and antimony metal, for both military and industrial applications.

Antimony and Gold Market Context

Antimony, a critical mineral for defense and high-tech applications, has seen growing demand due to its use in munitions, semiconductors, and energy systems. The U.S. Government's support for domestic critical minerals projects, including advanced permitting and funding, highlights the strategic importance of Nova's antimony production plans. Gold, a key component of the Estelle Project, continues to benefit from strong market prices, further enhancing the project's economic value.
