Pantera Minerals (ASX: PFE) (OTCQB: PTMLF) Delivers High-Grade Antimony Results of up to 19.2% at Gillham Project in Arkansas

Jane Morgan Management

Key Facts:

• Pantera Minerals has announced high-grade antimony, silver and base metal results from its Phase 2 exploration programme at the 100%-owned Gillham Project in southwest Arkansas, including 63.8 g/t silver and 7.55% antimony from the Stewart Prospect and 19.2% antimony from Stewart North.
• Phase 2 exploration has expanded mineralised trends across multiple prospects, with the Stewart and May anomalies each extending approximately 400–500 metres within a broader 2-kilometre mineralised trend, supporting the potential for a district-scale polymetallic system.
• The Gillham Project covers approximately 5,000 acres and hosts more than 18 historical antimony and silver workings, none of which have previously been tested by modern drilling.
• Results from the May Prospect represent the first modern rock chip assays from the site, returning antimony grades of up to 9.3%, upgrading it to a high-priority drill target alongside the Stewart and Davis prospects.
• Pantera's immediate work programme will focus on final target ranking, drill programme design, and maiden drilling of priority antimony and polymetallic targets, which the company considers a significant value catalyst.

Pantera Minerals Limited (ASX: PFE) (OTCQB: PTMLF) has announced further high-grade antimony, silver and base metal results from its Phase 2 exploration program at the 100%-owned Gillham Project in southwest Arkansas, U.S.A.

The latest results continue to validate Gillham as a high-priority U.S. critical minerals project, with rock chip sampling confirming high-grade antimony and polymetallic mineralisation across multiple prospects, including Stewart, May and Antimony Bluff.

Significant results include:

• 63.8 g/t silver, 7.55% antimony, 8.6% zinc and 7.44% lead from sample GR055 at the Stewart Prospect
• 19.2% antimony, 12.25 g/t silver and 1.1% lead from sample GR058 at Stewart North
• 15% antimony from sample GR063 at Antimony Bluff
• 9.3% antimony from sample GR072 at the May Prospect
• 4.9% antimony from sample GR069 at the May Prospect

The Phase 2 program has expanded and refined several mineralised trends, confirmed the relationship between surface geochemistry and historical workings, and identified multiple priority targets for drill testing.

High-grade rock samples were returned from the previously reported antimony anomalies at the Stewart and May prospects, which extend approximately 400 metres and 500 metres respectively. Both anomalies sit within a broader 2 kilometre mineralised trend, supporting the potential for a district-scale antimony, silver and polymetallic system.

The Gillham Project covers approximately 5,000 acres across the Gillham East and Gillham West project areas and hosts more than 18 historical antimony and silver workings. Despite its historical production profile, the district has not previously been tested by modern drilling.

Barnaby Egerton-Warburton, Executive Chairman and CEO, commented:

“Phase 2 exploration has further strengthened our confidence in the Gillham Project, with expanded antimony, silver, and base metal anomalism confirming the scale and continuity of multiple mineralised systems across the project area. The latest soil and rock-chip results have extended several priority target zones and identified new areas for follow-up exploration.

The strong correlation between high-grade rock-chip results, extensive soil anomalies and historical workings continues to support the potential for significant mineralisation at depth. Importantly, the Phase 2 program has refined multiple high-priority drill targets as we advance toward our maiden drilling campaign, which we believe represents a significant value catalyst for the Company.”

At the Stewart Prospect, historical records indicate the Stewart Mine produced approximately 1,000 tonnes of stibnite from small-scale surface workings. Recent sampling has upgraded the prospect as a priority drill target, with high-grade antimony, silver, lead and zinc results supported by coincident soil anomalism of up to 2,660ppm antimony along the broader Stewart and May trend.

At the May Prospect, the latest rock chip assays represent the first modern rock chip results received from the prospect and validate recent high-grade soil anomalies identified by Pantera. The results have upgraded May to a high-priority drill target, with antimony results of up to 9.3%.

Follow-up field mapping and sampling at Antimony Bluff also returned high-grade antimony, including 15% antimony from sample GR063. Additional soil sampling was completed south of the prospect to assess further areas of anomalous antimony mineralisation beneath shallow cover.

Pantera’s immediate work program at Gillham will focus on advancing the project toward maiden drilling. Planned activities include final target ranking and drill program design, maiden drilling of priority antimony and polymetallic targets at the Davis, Stewart and May prospects, and ongoing assessment of additional U.S.-based critical minerals opportunities that complement the Company’s strategy.
