On 28 August 2026, Mr. Gerteisen attended a roundtable in Fairbanks, Alaska, alongside DoE officials, U.S. Secretary of Energy Chris Wright, Senior Advisor Audrey Barrios, and Acting Principal Deputy Assistant Secretary Andy Rapp. The invite-only roundtable also included representatives from the Alaska Miners Association and other Alaska-based mining companies.

Secretary Wright reiterated the importance Nova Minerals’ antimony production from Estelle will have in supporting the U.S. Government’s domestic critical minerals objectives.

To underpin mining, processing, and refining operations across Alaska, Secretary Wright discussed the DoE’s incoming initiatives to improve power generation capability and transmission in the state. These DoE initiatives are expected to ensure sufficient power supply for Nova’s phase 2 expansion plans for its vertically integrated military-grade antimony trisulfide production strategy.

Following Secretary Wright’s opening remarks, Nova CEO Mr. Gerteisen provided officials with an update on Estelle, where the 2026 field season is underway, with three diamond drill rigs operating on site 24 hours a day, seven days a week, for the season.

In parallel, a barge containing almost 500 tons of crushing, ore sorting, milling, flotation, and refining equipment is expected to arrive early next month at Nova Minerals’ planned antimony trisulfide processing and refinery site at Port MacKenzie, Alaska. Construction will commence once the barge arrives, with phase 1 antimony trisulfide production scheduled for 2027.

Phase 1 of Nova Minerals’ planned antimony trisulfide production is fully funded by a US$43.4 million DoW award supporting the establishment of a domestic antimony supply chain. Upon completion, the DoW-funded phase 1 antimony refinery is expected to serve as a strategic U.S. processing and toll-treatment facility capable of producing refined antimony products for defense, industrial, and critical technology supply chains.

Nova Minerals CEO, Mr Christopher Gerteisen, commented:

“Nova Minerals’ participation in the U.S. Department of Energy roundtable emphasizes the strategic importance the U.S Government has placed on our Alaskan Estelle Gold and Critical Minerals Project and its fast-tracked antimony production for the domestic supply chain.

“Antimony is essential to our national and economic security, with applications in defense, energy storage, and electronics. Roundtable discussions reinforced the critical role antimony production from Estelle will have in supporting U.S. critical minerals security.”
