Highlights

  • Fully Funded Pilot Plant: Engineering and design covers the Whiskey Bravo front-end processing site, Port MacKenzie beneficiation plant, Port MacKenzie refinery (Figure 1) and supporting infrastructure.
  • Antimony Trisulfide Production: Engineered to meet U.S. Department of War military-grade quality specifications using a proprietary cleaner hydrometallurgical processing method.
  • Building a Secure American Fully Integrated Antimony Supply Chain: The pilot plant is a critical first step in fast-tracking domestic antimony production in Alaska. With a modular design that enables future expansion through the addition of refining circuits, including antimony trioxide and antimony metal production, the facility will serve as a scalable processing hub for feedstock from Estelle, as well as regional and global projects.
  • Construction Expected to Commence this Quarter: Process plant equipment procurement underway with key components now delivered or in transit to the project site to support construction in the coming months (Figures 3 to 6).
