Pantera Drills First Test at High-Grade Antimony Project in Arkansas

Pantera CEO Barnaby Egerton-Warburton said the company had moved from surface exploration to directly testing the system at depth after identifying high-grade rock chips, soil anomalies and historical workings. The current drilling is the first known modern subsurface test of the Davis system and the broader mineralised structures beneath the historic workings.

Antimony is classified as a critical mineral in the United States, with domestic supply heavily reliant on imports. The Gillham Project sits in a historic mining district with more than 18 past antimony and silver workings. Mining there was largely shallow and near-surface. Pantera's current campaign is designed to provide geological and structural information to guide follow-up drilling, with core to be logged and assayed progressively.

Results will be released as they come in, and the company will use them to update its geological model for the 5,000-acre project, which spans the Gillham East and Gillham West areas. The program targets the Davis, Stewart and May prospects, testing whether the high-grade surface mineralisation extends to depth. If successful, the drilling could de-risk the project by confirming a sizeable resource in a critical mineral that the US mostly imports from China and other foreign sources.
