American Tungsten and Antimony (ASX:AT4) has successfully produced its first antimony ingots, completed as part of metallurgical testwork using materials from the Australian company’s Antimony Canyon Project in Utah.

These ingots – produced at an independent third-party facility – will serve as proof-of-concept, the Aussie company said today, in its strategy to establish a domestic mine-to-metal critical minerals supply chain.

“Production of our first antimony ingots is an important milestone in our development pathway,” managing director Andre Booyzen declared.

These first antimony ingots will now be put together with AT4’s recent concept study and plant design (drawn up by Metso), which had already demonstrated the potential to build a smelter in the U.S. before the end of CY28.

“We’re fast-tracking our plans in the U.S. across many fronts, with exploration and drilling underway at Antimony Canyon, growth on our project portfolio by executing on strategic acquisition opportunities, and positioning AT4 on a corporate front through a proposed Nasdaq listing,” Mr Booyzen said.

“Production of the ingots comes at a very busy time… but does provide tangible evidence that we are on the right track in helping establish a mine-to-metal critical minerals supply chain in a major global market.”

Other materials not turned into ingots remain stockpiled at ACP. These, The Market Link understands, will be used in ongoing metallurgical testing.

Elsewhere, as Mr Booyzen mentioned, the company is continuing to push forward with its grand Nasdaq plans; American Tungsten and Antimony’s chiefs are still hoping that U.S. IPO goes through in CY26’s second quarter.

Exploration and drilling are still rolling on at ACP, too, and AT4 is still looking at expansion opportunities across the States to partner with their flagship project.

ATAA has long been striving to re-establish stronger domestic production (read: in the U.S.) of critical minerals vital to defence, clean energy, and strategic manufacturing, as markets look for ex-China options.

Heading into Thursday, AT4 has been fetching 14cps.
