Felix Gold (ASX:FXG) has established Frontier Antimony Refinery, a US-focused platform for antimony refining, metal production, marketing, and downstream development.
The new company will access the antimony feedstock from Felix’s Treasure Creek Project in Alaska, providing it with a domestic source of ‘military-grade’ concentrate.
At Treasure Creek, antimony ore is currently being extracted, sorted, stockpiled, and containerised under permit.
Frontier is also entering into a commercial supply agreement with Felix Gold for the purchase of Treasure Creek’s antimony-bearing material, establishing a clear pathway for refining and production.
The new processing company has been established as a Delaware corporation in order to engage strategic partners, investment capital, and government stakeholders, with a focus on strengthening domestic US critical minerals supply chains.
Executive Director Joseph Webb says that as the US faces a growing supply crisis for antimony, Frontier provides a solution as a dedicated US antimony development platform.
“What sets Frontier apart is access to feedstock. One of the greatest challenges facing antimony-refining businesses globally is securing reliable ore supply,” Webb says.
“Frontier has an anchor domestic feedstock source through the Treasure Creek Project in Alaska, where antimony-bearing material is already being extracted, sorted, stockpiled, and containerised under permit.
“Importantly, Treasure Creek ore has demonstrated the ability to meet military-grade antimony concentrate specifications as direct shipped ore, providing a strong foundation for the development of domestic refining capability.”
Felix Gold notes that while Frontier will initially take feedstock from Treasure Creek, it is intended to eventually become a “broader processing, refining, and marketing platform capable of sourcing additional domestic antimony feedstock over time”.
As such, the company is assessing commercial pathways to develop a domestic US antimony supply chain.
Felix Gold also notes that Frontier will focus initially on antimony, but may be evaluated for broader applications across other critical minerals and metals.
Frontier is focused now on advancing commercial supply arrangements with Felix Gold, as well as activities relating to technical development, toll treatment, refining pathways, and site selection.
Alongside this, Felix Gold is continuing with extraction, sorting, stockpiling, and other logistics at Treasure Creek, while also advancing exploration and development across its gold and antimony targets.
Felix Gold is advancing antimony and gold opportunities in Alaska’s Fairbanks Mining District.
