Nova Minerals Corp has achieved a key milestone in establishing a domestic antimony supply chain, with almost 500 tons of processing and refining equipment currently en route to its plant site in Alaska.

The shipment departed Seattle by barge on August 26, 2026, and comprises more than 40 shipping containers and oversized loads of crushing, ore sorting, milling, flotation, and refining equipment. The barge is expected to arrive at Port MacKenzie in early September, enabling construction work on the processing facilities to begin.

Following the completion of engineering and design work in July 2026, Nova Minerals consolidated the equipment after acquiring a recently decommissioned modern processing facility in North America alongside other regional processing machinery.

The company split the antimony project between two primary operational sites. The Whiskey Bravo location handles initial ore crushing and sorting, while the Port MacKenzie facility manages refining and beneficiation. The plant is designed to process stibnite-bearing material initially into antimony trisulfide under a U.S. Department of War project, with modular scalability allowing for future expansion into refined products including antimony metal and trioxide.

The development is fully funded by a US$43.4 million Defense Production Act Title III award. By acquiring and repurposing existing modern equipment rather than fabricating new machinery from scratch, the company cut procurement timelines and capital costs. First antimony production from the Port MacKenzie plant is targeted for 2027.

“A key part of our strategy has been to acquire existing, modern processing equipment and mobilize it to Alaska, rather than build new equipment from scratch. That decision allowed us to move faster and more cost-effectively as we construct our processing plant at Port MacKenzie and work toward first antimony production in 2027.”
