West Susitna Access Road Advances with Geotechnical Drilling and $25 Million Additional Funding Approved
Rhea-AI Summary
Nova Minerals (NYSE American: NVA, ASX: NVA) reports that geotechnical drilling is underway on the proposed 78.5-mile West Susitna Access Road and that the Alaska Industrial Development and Export Authority (AIDEA) has approved up to $25 million in additional funding over 2026/2027 to advance road predevelopment.
The year-round road is planned to link Nova Minerals’ Estelle Gold and Critical Minerals Project with its future Port MacKenzie antimony refinery via a connection to a separate 22-mile ADOT&PF road and major Susitna River bridge. According to Nova Minerals, ADOT&PF has completed or nearly completed most 2026 drill holes at key material sites and bridge crossings, with numerous environmental and technical studies finished or in progress. Phase 1 of Nova’s antimony trisulfide production is described as fully funded by a $43.4 million U.S. Department of War Defense Production Act Title III award, supporting a domestic antimony supply chain targeted for 2027 production.

Anchorage, Alaska, Sept. 01, 2026 (GLOBE NEWSWIRE) -- Nova Minerals Corp (“Nova Minerals” or the “Company”) (NYSE American: NVA | ASX: NVA) is pleased to report that geotechnical drilling is underway and that the Alaska Industrial Development and Export Authority (“AIDEA”) has authorized up to
Highlights
- The West Susitna Access Road is a transformative 78.5-mile, year-round all-weather road that will support critical mineral development in Alaska’s West Susitna region, including Nova Minerals’ Estelle Project, by improving access, reducing development costs, and supporting regional economic growth. It will connect to a separate 22-mile Alaska Department of Transportation & Public Facilities (ADOT&PF) road project, including a major bridge over the Susitna River, linking the area to the existing road network (Figure 1).
- The AIDEA board has authorized up to
$25 million in funding to advance geotechnical drilling and other essential works for the West Susitna Access Road over 2026/2027. - ADOT&PF geotechnical investigations are progressing well, with 2026 fieldwork and most drill holes completed or nearing completion at key material sites and bridge crossings (Figure 2), and numerous environmental studies now completed.
- Nova Minerals is a first mover in developing a fully integrated antimony mining, processing and refining operation in Alaska to provide a secure and reliable domestic supply of a critical mineral essential to U.S. national and economic security.
On August 27, 2026, the AIDEA board approved up to
The funding will also progress the permitting, hydrologic, engineering, and access work that directly supports it.
"This is the work that turns a route on a map into a road that can actually be built,” said AIDEA Deputy Executive Director Brandon Brefczynski. “The Board’s unanimous action keeps the project on schedule for the upcoming field seasons and moves us another step closer to unlocking one of the most promising resource corridors in the state.”
This important next step builds on the Alaska Department of Transportation and Public Facilities’ (ADOT&PF) extensive geotechnical investigations and drilling program undertaken in 2026 as part of the predevelopment work for the West Susitna Access Road, supporting the preliminary design of the proposed roadway, bridges, culverts, and potential construction material sites.
Field investigations have been completed at three material sites, with work at a fourth site nearly complete. Additional laboratory testing and technical analysis are ongoing. Fourteen material sites still require field investigation. These locations have received the necessary environmental and land-use permits and are prepared to proceed once authorization is received from the Federal Highway Administration.
Substantial progress has also been made at the proposed Little Susitna River and Susitna River bridge crossings. At the Little Susitna River Bridge, seven of eight planned test holes and two of three planned penetrometer investigations have been completed.
At the Susitna River Bridge, drilling has been completed at four primary bridge pier locations using barge-supported equipment. The remaining in-river pier investigations are planned for the May 15 through July 15, 2027, permitted in-water work window. The remaining abutment and approach investigations are fully permitted and awaiting federal authorization.
In addition to the drilling, numerous environmental and other studies have also been completed or are nearing completion including:
Overall, the West Susitna Access Road is expected to cover 78.5-miles, beginning approximately 1.4 miles west of Alexander Creek and extending to Nova Minerals’ Whiskey Bravo airstrip and mineral exploration camp (Figure 1).
Phase 1 of Nova Minerals planned antimony trisulfide production is fully funded by a
Upon completion, Nova Minerals’ antimony refinery in Port MacKenzie, Alaska, 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 welcomes the AIDEA board's unanimous funding approval, authorizing an additional
"The funding approval demonstrates the ongoing local support for critical minerals projects in the region that strengthen U.S. national and economic security.
"This vital piece of infrastructure will increase accessibility to the site, providing safe and reliable road access throughout the year, supporting our efforts to establish a fully secure, vertically integrated antimony supply chain.”
