Nova Winter Freight Haul Underway

(“Nova” or the “Company”) (NASDAQ: NVA) (ASX: NVA) (FRA: QM3) ) is pleased to announce that the mobilization of heavy equipment to the Estelle Project is underway via the Company’s winter snow road, approximately 150km from Willow. (Figure 1). Ideal winter conditions allowed snow road construction to commence in early December, which involved pre-packing snow, water-flooding for ice thickening at major river crossings, and minor brush clearing. This winter has delivered near perfect snow road conditions with exceptionally cold temperatures that are favorable for the construction of ice bridges over 1.5m (5ft) thick. These bridges are capable of supporting freight loads well over 100,000lb (45,000kg) while preserving a hard snowpack base.

Nova rapidly assembled an Engineering, Procurement and Construction Management (EPCM) team tasked with sourcing heavy equipment from across the contiguous U.S. and Alaska to aid in trail construction, airstrip expansion, and the extraction and processing of stibnite-bearing (antimony) ore. Equipment travelled via barge, rail, and truck to Nova’s freight staging yard and logistics center in Willow, Alaska, where to date 95% of major mining and processing equipment items have now been received. Equipment is then loaded onto ski-trailers for transport by low ground pressure vehicles or self-driven along the winter trail to the Estelle Project site.

Approximately 70% of the equipment has left the Nova freight yard in Willow via the winter road for delivery to the Estelle Project site. The next few weeks remain crucial to the winter freight mobilization effort. With cold temperatures (-26C/-15F) forecast for the foreseeable future, trail conditions should remain optimal, and the company is confident it will meet its objectives to deliver all essential mining and processing equipment required to commence antimony production on schedule.

Nova Minerals Limited is advancing one of the world’s largest undeveloped gold deposits into production and securing a US domestic supply of the critical mineral antimony. The Company is focused on the exploration and development of the Estelle Gold and Critical Minerals Project, located in Alaska, a tier-one mining jurisdiction.

Estelle hosts two defined multi-million-ounce gold resources, and more than 20 prospects distributed along a 35-kilometre mineralized trend, in the prolific Tintina Gold Belt, a province which hosts a >220 million ounce (Moz) documented gold endowment and some of the world's largest gold mines and discoveries including, Kinross Gold Corporation's Fort Knox Gold Mine. In parallel, Nova is advancing its critical minerals strategy, fully-funded by a US$43.4 million U.S. Department of War award to develop a domestic antimony supply chain, targeted for production in late 2026/2027.
