It’s not just Tungsten Mining NL making moves on the ASX this morning; fellow defence metals player American Tungsten and Antimony (ASX: AT4) also shot to the top of the HotCopper boards pre-market on news of a refinery restart.

The refinery in question? The Del Sol Hydromet (DSH) refinery located in Nevada, USA, which will soon be processing antimony-bearing ore taken from ASX-listed AT4’s White Spar Antimony mine in Arizona.
Antimony flake produced at the delivery end of the refinery will go to potential offtake partners – including US gov’t defence entities and major private defence players.
In the company’s eyes, this is part of its “mine-to-metal” approach in the US, where defence metals have been increasingly on the radar of the Trump Administration in recent years.
“US policy increasingly requires domestic and allied supply of critical materials used in defense supply chains, and antimony sits at the centre of these requirements,” AT4 Exec. Chair Timothy Morrison said.
“This campaign is an important step in AT4’s strategy to establish a vertically integrated US supply chain for antimony.”
Focusing more on the here-and-now of the DSH refinery restart, Morrison’s views were complemented by AT4 CEO Casper Adson, who highlighted the company’s jumped the gun on getting the refinery fired up sooner than thought given a promising climate for defence metals.
“Commencing the restart campaign at the Del Sol refinery is a critical milestone for the Company,” Adson said.
“AT4 has fast-tracked the restart to demonstrate the capability of the Del Sol circuit using US-sourced material … [the] existing, permitted facility enables the circuit to be restarted without the need to add new infrastructure or lengthy permitting delays.”
All cards in order, the antimony flake produced by the company will go towards the production of antimony trisulphide, which is the hard metal desired for ammunition casings (both big guns and small guns); as well as going towards alloys for missiles.
