Anchorage Alaska, Aug. 25, 2025 (GLOBE NEWSWIRE) -- Nova Minerals Limited ("Nova" or the "Company") (NASDAQ:NVA) (ASX: NVA) (FRA: QM3) ) is pleased to report further momentum following senior U.S. Senator from Alaska Lisa Murkowski's recent site visit to the Estelle Gold and Critical Minerals Project in Alaska (Figures 1 and 2).

Highlights

In line with the strategic push for U.S. critical minerals independence.
Estelle independently identified as one of nine projects globally, and one of two in the U.S., with near term antimony production capability.

The Senator's visit and support underscores the project's strategic significance in potentially bolstering U.S. domestic mineral production and securing critical supply chains for essential commodities like antimony and gold. This support helps position Nova Minerals as a potential key player in the future of America's resource independence.

The Senator's visit underscores broader U.S. federal support — demonstrated through recent Presidential Executive Orders — to revitalize U.S. domestic rare earth and critical minerals production, and reduce reliance on foreign imports.

"A Strategic Priority for America's Mineral Security"

During a recent site visit to the Estelle Project, Senator Murkowski saw the scope and potential of Nova's operation. Her presence at the site appears to reflect the growing federal recognition of Alaska's potential role in bolstering America's mineral independence and supporting strategic projects that directly contribute to national and economic security.

In a public statement on March 21, 2025, Senator Murkowski addressed the urgent need for U.S. mineral security:

"Our lack of mineral security is our nation's Achilles' heel — a vulnerability that leaves us at the mercy of politically unstable and often adversarial nations for the basic building blocks of modern society. We import a wide array of minerals from those nations instead of producing minerals here at home, and we do it despite the potentially catastrophic threats that creates for our security, economy, and competitiveness," Murkowski said. "China knows this. Russia knows this. But, importantly, so do President Trump and his team. I appreciate their recognition of this major vulnerability and their immediate steps to tackle it. This new order is the most robust effort we have seen in some time — with more agencies directed to make greater use of their authorities to strengthen our domestic mineral security for the long-term."

Nova cautions that the above photos containing images of Stibnite are for illustrative purposes only showing what the Senator reviewed during her site visit. Visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. Visual estimates also potentially provide no information regarding impurities or deleterious physical properties relevant to valuations.

Broad-Based Support Builds Momentum

Senator Murkowski's visit adds to recent high-level governmental interest in Estelle including:

Alaska Governor Mike Dunleavy meeting with Nova's CEO, Christopher Gerteisen, reaffirming alignment with infrastructure priorities like the West Susitna Access Road, Port MacKenzie logistics enhancements, and Alaska LNG — critical elements to Estelle's development (ASX Announcement: 14 August 2025).
Australian Consul General Tanya Bennett visiting the site, further validating Estelle as a symbol of deepening U.S.–Australia collaboration in strategically vital minerals (ASX Announcement: 14 August 2025).
Members of Alaska's Congressional Delegation — including Senator Dan Sullivan, Representatives Nick Begich and Kevin McCabe, and Matsu Borough Mayor Edna DeVries —also expressed broad support following Nova's recent Alaska board visit (ASX Announcement: 24 July 2025).
Independent research firm RFC Ambrian identifying the Estelle Project as one of only nine projects globally, and one of only two in the U.S., of which the other one was Perpetua Resources (market cap ~ A$2.93 billion as of 22 August 2025) Stibnite project, with near-term antimony production capability in its critical minerals commodity report "Antimony - A Market Under Severe Stress" released in February 2025

Estelle: Dual Commodity Asset with Strategic Momentum

Nova CEO, Mr Christopher Gerteisen commented: "We're witnessing a convergence of policy, diplomacy, and local support around Estelle. Recognized for its significant gold and antimony potential — and highlighted in the RFC Ambrian report as one of only two U.S. projects with near-term antimony production capability — Estelle is emerging as a strategic asset. Growing interest from both the U.S. Department of Defense and the Australian government underscores momentum far beyond routine exploration. Notably, Nova has already accumulated surface stibnite stockpiles potentially capable of producing antimony trisulfide for U.S. strategic purposes. While the material requires modest further concentration to meet military specifications, this positions Nova as a potential critical contributor to national defense supply chains."

In Line with Executive Orders

Estelle's advancement is in line with recent Presidential executive orders:

These executive orders were intended to accelerate domestic mineral project development to underpin economic and national security objectives.
