US Pantera Launches First Drilling Campaign at Gillham Antimony-Silver Project

en.Wedoany.com Reported - On August 18, 2026, Pantera Minerals commenced its first diamond drilling campaign at the Gillham antimony-silver project in southwestern Arkansas, USA. The program plans 10 drill holes totaling approximately 1,500 meters, marking the project's first modern underground drilling.

The drilling, carried out by Dycus 3D Drilling Company, will focus on testing mineralized structures beneath and adjacent to the historic Davis, Stewart, and May mining areas, to determine whether surface antimony, silver, and polymetallic mineralization extends to depth, and to analyze mineralization trends and geological controls.

Pantera previously defined drill targets through geological mapping, soil geochemistry, and rock chip sampling. Two antimony anomalies with strike lengths of approximately 400 meters and 500 meters have been identified within the Stewart–May mineralized zone, with peripheral anomaly trends extending approximately 2 kilometers. Selective rock chip samples returned up to 19.2% antimony and 63.8 g/t silver, although these spot samples do not represent the average grade or width of the mineralized structures.

Davis is the largest historic mining area within the project scope, and this drilling campaign will test the subsurface continuation of local silver, copper, lead, and zinc mineralization. Previous rock chip samples returned 1.96% copper, 1.465% zinc, and 0.29% lead, as well as 4.79% lead, 0.22% copper, and 20.5 g/t silver.

The Gillham project covers approximately 5,000 acres, or about 2,023 hectares, encompassing more than 18 historic antimony-silver mines and mining remnants. Core will be logged, cut, and assayed as drilling progresses, with results used to update the project's geological model and determine priorities for subsequent infill or step-out drilling.
