Nova Minerals Confirms Alaska Processing Plant Capacity Of 216K Tons/Year

Newly acquired processing plant, which is to be constructed at Port MacKenzie, Alaska, has confirmed front-end crushing, grinding and concentration capacity of approximately 216,000 tonnes per annum (tpa). This substantial processing capacity provides a scalable platform for future commercial antimony production, with capacity modelling indicating potential refined antimony production of up to approximately 20,000 tpa, subject to feed grade, additional downstream refinery equipment and other operating requirements.

The processing infrastructure provides a strong foundation for Nova's strategy to establish a fully integrated U.S. domestic antimony and critical minerals processing and refining hub in Alaska, with the capability to produce both antimony metal and antimony trisulphide. The facility is also intended to support processing of feedstock from Nova's Estelle Project and potentially suitable third-party mineral sources, creating opportunities to expand domestic processing capacity and strengthen U.S. critical minerals supply chains.

Highlights

216,000 tpa processing capacity: Plant crushing, sorting, grinding and concentration infrastructure provides significant capacity for future commercial operations.
Two parallel grinding circuits: Two mill trains, each with approximately 108,000 tpa capacity, provide operational flexibility, staged expansion opportunities, and capacity for additional suitable mineral feedstocks.
Phase 1 pilot-scale refinery up to 600 tpa: Initial production of military-grade antimony trisulphide and >99.65% antimony metal is being advanced under the fully funded $43.4 million Department of War (DoW) supported project.
Significant full-scale commercial expansion potential: Capacity modelling indicates potential refined antimony production of approximately 9,400 – 20,000 tpa, with 5 – 10% Sb feed grade, subject to additional downstream refinery equipment and other operating requirements.
Multi-commodity processing opportunity: Plant infrastructure could also support processing of tungsten, gallium, bismuth, tellurium, arsenic, and other suitable critical mineral feedstocks.
Potential regional toll-processing hub: Port MacKenzie provides a strategic processing destination for Nova's Estelle Project and potentially other third-party mineral producers.
