• The briefing will occur before a meeting between President Trump and Australian Prime Minister Anthony Albanese on October 20, 2025, in Washington, D.C.

Nova Minerals shares jumped 110% on Tuesday following news that the Australian Ambassador to the U.S. requested a briefing on the company’s Alaska mining project.

The request came from Dr. Kevin Rudd, Australian Ambassador to the U.S. He asked Nova to provide an update on its Estelle Gold and Critical Minerals Project.

The briefing is scheduled before a meeting between Australian Prime Minister Anthony Albanese and President Donald Trump on October 20, 2025, in Washington, D.C.

Nova’s U.S.-listed ADRs closed up 110.30% but fell about 16% in after-hours trading. The Australia-listed shares gained over 80% during local trading.

The Estelle Project sits roughly 100 miles northwest of Anchorage, Alaska. Nova describes it as among the world’s largest undeveloped gold assets.

Gold and Antimony Holdings

The mining site is projected to hold more than 9.9 million ounces of gold across its four most promising deposits. At Tuesday morning’s gold price of $4,140 per troy ounce, that’s worth approximately $41 billion.

The site also contains antimony, a critical mineral used in defense applications and battery technology.

In early October, the Department of Defense announced a $43.4 million investment in a Nova Minerals subsidiary. The funding targets development of domestic antimony sources.

The Australian Consul-General visited the Estelle site in August. That visit highlighted the project as a key part of U.S.-Australia collaboration on critical minerals.

Mining Sector Rally

Other Australian mining companies traded higher following Nova’s announcement. Fortescue Metals Group and Australian Mines saw gains, along with Rio Tinto.

The Trump administration has increased focus on domestic supply chains for critical minerals and metals. This has benefited several mining companies operating in the U.S.

MP Materials operates the only functional rare earth mine in the U.S. The stock is up more than 500% year-to-date.

Trilogy Metals holds a 50% stake in a major mineral mining project under development in Alaska. Shares have gained more than 490% this year.

Lithium Americas is developing what could be the largest lithium mine in the Western Hemisphere. The stock has risen over 180% in 2025.

Support from U.S. federal, state, and local agencies has strengthened Nova Minerals’ strategic position. Government backing has brought increased attention to the company’s Alaska operations.

The formal request for a briefing ahead of the Trump-Albanese meeting marks a step forward in U.S.-Australia efforts to secure critical mineral supply chains.

Nova Minerals was asked to prepare materials on both its gold and critical minerals operations at the Estelle site. The briefing will inform discussions between the two leaders later this month.
