Nova Minerals has kicked off geotechnical drilling for the West Susitna Access Road after AIDEA approved up to US$25 million in additional funding, aiming to unlock critical mineral development and improve logistics for its Estelle Project and antimony refinery.
- US$25 million funding approved by AIDEA for West Susitna Access Road
- 78.5-mile all-weather road to connect Estelle Project to Port MacKenzie refinery
- Significant progress in geotechnical drilling and environmental studies
- Project supports US domestic critical mineral supply chain
- Federal permits pending for remaining drilling and construction activities
Major Funding Boost for Strategic Alaska Road
Nova Minerals Corp (ASX:NVA, NYSE American:NVA) has secured a crucial US$25 million injection from the Alaska Industrial Development and Export Authority (AIDEA) to push forward the West Susitna Access Road project. This funding approval comes as geotechnical drilling is already underway, marking a significant step towards building a 78.5-mile, year-round all-weather road that will serve as a vital artery for mineral development in Alaska’s West Susitna region.
The road is designed to link Nova’s Estelle Gold and Critical Minerals Project with the planned Port MacKenzie antimony refinery, enhancing access and potentially lowering development costs. It will tie into a 22-mile road project managed by the Alaska Department of Transportation & Public Facilities (ADOT&PF), including a major bridge over the Susitna River, connecting the area to the wider road network.
Geotechnical Work Advances with Federal Permitting Pending
ADOT&PF’s geotechnical investigations have made solid progress during the 2026 field season, with most drill holes at key material sites and bridge crossings either completed or nearing completion. Fieldwork has been conducted at three material sites with a fourth nearing completion, while fourteen additional sites are ready to proceed pending federal authorization from the Federal Highway Administration.
Bridge investigations are also advancing, with significant drilling completed at the Little Susitna River and Susitna River crossings. Some in-river pier investigations are scheduled for the 2027 permitted in-water work window, highlighting the project’s phased approach to complex engineering challenges.
Infrastructure Underpins Critical Minerals Strategy
Nova Minerals is positioning itself as a first mover in establishing a fully integrated antimony mining and refining operation in Alaska, supported by a US$43.4 million award from the U.S. Department of War under the Defense Production Act. The Port MacKenzie refinery aims to produce refined antimony products critical to U.S. national security and industrial supply chains.
CEO Christopher Gerteisen described the funding approval as a milestone that underscores local support for critical minerals projects and their role in strengthening U.S. economic and national security. The road will provide safe, reliable year-round access to the Estelle Project, facilitating Nova’s ambition to secure a domestic supply chain for antimony and gold.
Environmental and Regulatory Steps in Progress
Alongside drilling, numerous environmental studies have been completed or are nearing completion, addressing key permitting requirements. However, some activities, including remaining drilling and construction at bridge sites, await final federal authorizations, which could influence the project timeline.
The West Susitna Access Road is more than just infrastructure; it is a strategic enabler for unlocking one of Alaska’s most promising resource corridors. Its completion will not only support Nova’s Estelle Project but also catalyse regional economic growth by improving access to critical mineral resources.
Bottom Line?
Federal permits will be the next hurdle for Nova Minerals as it pushes to transform the West Susitna Access Road from plans to pavement, underpinning its critical minerals ambitions.
Questions in the middle?
- How quickly will federal authorizations be granted to maintain project momentum?
- What are the potential cost implications if permitting or environmental hurdles delay construction?
- How will improved infrastructure impact Nova’s timeline for antimony production and gold development?
