The document shows Nova Minerals Limited submitting a Form 6-K that attaches a press release titled “U.S. Department of War Awards $43.4M to Alaska Range Resources to Secure Antimony Supply.” This signals official recognition of a substantial $43.4M U.S. government award connected to antimony, a critical mineral, through Alaska Range Resources.
