Pantera Minerals lifts Gillham antimony targets after high-grade Arkansas assays

Pantera Minerals reported new rock-chip and soil results from its Gillham Project in southwest Arkansas, including antimony grades up to 19.2% and silver up to 63.8 g/t. The results sharpen drill targets at Stewart, May and Davis as the company moves toward maiden drilling at the U.S. critical minerals site.

Why it matters: - Gillham is advancing as a U.S. critical minerals target with high-grade antimony, silver, lead and zinc showing up across multiple prospects. - The latest assays increase the case for a district-scale polymetallic system and help Pantera Minerals narrow where to drill first. - Antimony is a strategic mineral with U.S. supply-chain relevance, so new high-grade results can matter for project value and partner interest.

What happened: - Pantera Minerals Limited released further assay results from Phase 2 exploration at the 100%-owned Gillham Project in southwest Arkansas. - Rock-chip sampling returned 19.2% antimony, 12.25 g/t silver and 1.1% lead from sample GR058 at Stewart North. - Sample GR055 at the Stewart Prospect returned 63.8 g/t silver, 7.55% antimony, 8.6% zinc and 7.44% lead. - Sample GR063 at Antimony Bluff returned 15% antimony. - Sample GR072 at the May Prospect returned 9.3% antimony. - Sample GR069 at the May Prospect returned 4.92% antimony. - Pantera said the Phase 2 program refined multiple drill targets ahead of a maiden drilling campaign.

The details: - The Stewart and May prospects each returned new high-grade samples from coherent antimony anomalies extending about 400 metres and 500 metres, respectively. - Those anomalies sit within a broader two-kilometre trend, supporting the possibility of a district-scale antimony, silver and polymetallic system. - The Gillham Project covers about 5,000 acres across the Gillham East and West project areas. - The district includes more than 18 historical antimony and silver workings. - The project has not previously been tested by modern drilling. - Historical records indicate the Stewart Mine produced about 1,000 tonnes of stibnite from small-scale surface workings. - The first modern rock-chip assays from the May Prospect validated recent soil anomalies and upgraded May to a high-priority drill target. - Follow-up field mapping and sampling at Antimony Bluff refined the geological interpretation, extended the known mineralised area and identified additional structural controls on mineralised quartz veins. - Infill soil sampling at the Andrews Gold Prospect and Antimony Bluff included 75 soil samples to better define geometry, continuity and scale in under-sampled areas.

Between the lines: - The strongest results are not isolated hits. The combination of soil anomalies, rock-chip grades and historical workings suggests continuity across the project area. - Pantera is shifting from broad prospecting to target ranking, which usually signals a project moving closer to a drilling decision. - Executive Chairman and CEO Barnaby Egerton-Warburton said the work has strengthened confidence in the scale and continuity of mineralised systems and pointed to maiden drilling as a potential value catalyst.

What's next: - Pantera will finalize target ranking and drill program design at Gillham. - Maiden drilling is planned for priority antimony and polymetallic targets at the Davis, Stewart and May prospects. - The company will continue assessing additional U.S.-based critical minerals opportunities that fit its strategy. - Pantera also said the higher-priority focus is now on the Davis, Stewart and May prospects as it advances toward drilling.

The bottom line: - Gillham is emerging as Pantera Minerals’ leading U.S. critical minerals asset, with new assays pushing antimony-rich targets toward the drill stage.
