Pantera Expands U.S. Critical Minerals Portfolio with Antimony-Silver Project in Arkansas

Jane Morgan Management

Perth, Australia – Pantera Lithium Limited (ASX:PFE) has expanded its U.S. critical minerals portfolio with the acquisition of two highly prospective project areas covering approximately 5,000 acres in southwest Arkansas. The new ground hosts multiple historical antimony and silver mines that have seen no modern exploration for nearly a century.

The Gilham Antimony-Silver Project marks Pantera’s first step into critical commodities beyond lithium and builds on the Company’s successful track record in Arkansas, including the recent A$40 million sale of its Smackover Lithium Project to EnergyX.

Pantera has entered into an exclusive abstract agreement with Lafayette County Abstract Inc., giving it sole rights to conduct expedited mineral ownership searches across Sevier County. This provides the Company with a dominant land position in one of Arkansas’s most promising but under-explored historic mining districts.

Fieldwork — including geological mapping, sampling and drone geophysical surveys — is set to begin immediately to define drill-ready targets for antimony, silver, lead, zinc and copper mineralisation.

Executive Chairman and CEO Barnaby Egerton-Warburton said the acquisition reinforces Pantera’s U.S. growth strategy at a time when critical minerals are central to supply-chain security and energy transition:

“This new project area represents an important next step for Pantera as we broaden our focus into U.S. critical minerals. The region has a long history of silver and antimony production, yet remarkably it has seen little to no modern exploration for nearly a century.

Pantera’s evaluation identified more than 18 historic mines and workings that have seen no work for nearly 100 years which are now captured in the Pantera Project area. The absence of modern exploration gives Pantera a material first-mover advantage to assess what appears to be one of the state’s most promising yet under-explored historic mining districts.”

Egerton-Warburton added that Arkansas’s pro-growth policies under Governor Sarah Huckabee Sanders and a supportive U.S. federal stance on domestic critical-minerals development position the state as a Tier-1 jurisdiction for new investment.

Pantera remains fully funded for its U.S. exploration programs, with a cash balance of approximately A$2 million and a further A$2 million payment due from EnergyX on 1 July 2026.
