Nova Minerals Corp describes how a July 20, 2026 Executive Order titled “Securing America’s Defense Supply Chains and Ensuring Domestic Acquisition of Critical Materials” strengthens U.S. policy favoring domestic and allied sourcing of critical minerals such as antimony, with end-to-end supply-chain traceability and restrictions on adversary-linked suppliers. The company says this Executive Order “highlights the strategic relevance” of its integrated antimony project in Alaska.
Nova Minerals is developing a fully integrated U.S. domestic antimony supply chain, from an antimony mine at the Estelle Gold and Critical Minerals Project to a refining and toll-treatment hub at Port MacKenzie, Alaska, with first pilot-plant antimony production targeted for 2027. In October 2025 it was awarded a US$43.4 million Defense Production Act Title III award from the U.S. Department of War to support the mine and refinery. Engineering and design for the Port MacKenzie pilot plant are complete, equipment procurement is underway, and construction is expected to begin in the coming months.
Estelle is described as one of the world’s largest undeveloped gold deposits, hosting two defined multi-million-ounce gold resources and more than 20 prospects along a 35‑kilometre mineralized trend within the Tintina Gold Belt, a province with a >220 million ounce gold endowment. Nova Minerals links this development to U.S. resource security and national defense priorities.

Nova Minerals Corp reports it has completed engineering and design for its Estelle antimony pilot processing plant in Alaska. The fully funded pilot plant covers the Whiskey Bravo front-end site and the Port MacKenzie beneficiation and refinery facilities, plus supporting infrastructure.
The flowsheet is designed to treat stibnite-bearing material and produce antimony trisulfide meeting U.S. Department of War military-grade specifications, using a proprietary cleaner hydrometallurgical process. Procurement is underway, with major equipment secured and over 40 containers en route to Port MacKenzie, and construction is expected to commence this quarter.
The project is part of a strategy to build a secure, fully integrated U.S. antimony supply chain, supported by a US$43.4 million U.S. Department of War award and targeted for production in late 2026/2027. Nova is also advancing the Estelle Gold and Critical Minerals Project, which hosts two defined multi-million-ounce gold resources along a 35-kilometre mineralized trend.
Nova Minerals Corp director Joshua I. Girnun filed a Form 3 as an initial statement of beneficial ownership for the company’s securities. The filing does not report any buy, sell, or other transactions and shows no current holdings or derivative positions in this disclosure.
Nova Minerals Corp expanded its Board of Directors from five to six members and appointed Joshua (Josh) Girnun as a Class I director, effective July 1, 2026. He will receive standard non-employee director compensation and was deemed independent under NYSE American listing standards.
Girnun is a former JP Morgan metals and mining risk underwriting professional with advanced degrees in metals and energy finance and geosciences. His appointment aligns with Nova’s U.S.-focused critical metals strategy, including the Estelle Gold and Critical Minerals Project in Alaska and a US$43.4 million U.S. Department of War award to advance a domestic antimony supply chain targeted for late 2026/2027 production.
Nova Minerals Corp filed an 8-K to share a press release clarifying its market capitalization after redomiciling to the United States. Some investment websites had shown an incorrect value of about US$2.1 billion. Based on its current trading price and the shares issued in the redomiciliation, Nova states its market capitalization is about US$166 million. The company explains that as of June 16, 2026, Nova Minerals Limited had 458,140,036 ordinary shares outstanding, which were exchanged at a 1-for-12 ratio into 38,181,050 common shares of Nova Minerals Corp, with a small number of extra shares from rounding. The release also highlights Nova’s Estelle Gold and Critical Minerals Project in Alaska and notes a US$43.4 million U.S. Department of War award supporting development of a domestic antimony supply chain targeted for production in late 2026/2027.
Nova Minerals Corp reported new metallurgical test results from its Korbel deposit within the Estelle Project in Alaska. Bench-scale rougher flotation on low-grade ore around 0.39–0.42 g/t gold achieved gold recoveries above 95% at grind sizes of 250 microns or finer.
The test-work produced high-grade concentrates ranging from 14.7 to 26.7 g/t gold while pulling only 2–3% of the mass, sharply reducing material sent to downstream processing. The company links these results to a January 2024 S-K 1300 pit-constrained Korbel resource of 425 Mt at 0.3 g/t for 4.05 million ounces of gold.
Nova highlights that integrating coarse particle flotation with a Carbon-in-Leach plant could lower capital and operating costs, improve recoveries and simplify the flowsheet, though this remains subject to ongoing Feasibility Study-level optimization and further test-work.
