Pantera Minerals Limited has confirmed high-grade antimony and polymetallic mineralization at its 100 %-owned Gillham Project in southwest Arkansas, USA, with first-pass modern exploration delivering results that validate the project’s potential and define multiple priority drill targets.

The results mark the first modern exploration undertaken at Gillham and include rock chip assays of up to 3.92 % antimony (Sb) alongside strong silver, lead, gold and base metal mineralization.
Soil sampling has further reinforced the scale of the mineralized system, with peak values of 2,660 ppm antimony, defining coherent anomalies extending up to ∼500 m in strike and supported by coincident arsenic, zinc and lead anomalism.
Strong Results Across Multiple Prospects
Key assay results include:
- 3.92 % Sb, 0.47 % Pb, 10.3 g/t Ag
- 1.1 % Sb, 1.32 % Pb, 6 g/t Ag
- 1.96 % Cu, 1.465 % Zn, 0.29 % Pb
- 4.79 % Pb, 0.22 % Cu, 20.5 g/t Ag
- 1.59 g/t Au and 0.47 g/t Au
These results confirm high-grade mineralization across several key prospects including Stewart, Davis Mine and newly identified gold targets, highlighting the polymetallic nature of the system and its potential for multiple mineralized zones.
Importantly, no drilling has previously been undertaken at Gillham, underscoring the significant exploration upside.
Large-Scale Mineralized System Emerging
Geochemical programs have identified two standout antimony anomalies along the Stewart–May trend, each extending approximately 400 m to 500 m, within a broader mineralized corridor exceeding 2 km in strike.
These anomalies are supported by coincident rock chip mineralization and remain largely untested, presenting compelling drill targets.
In addition, newly identified gold anomalism at the West Gillham area highlights further upside beyond antimony and base metals.
Executive Commentary
Barnaby Egerton-Warburton, Executive Chairman and CEO, commented:
“These initial results provide highly encouraging validation of the Gillham Project, with high-grade antimony in rock chips up to 3.92 % Sb directly associated with exceptional soil anomalies, up to 2,660 ppm Sb.
These results define coherent and compelling drill targets with the scale and continuity of the geochemical footprints supporting the presence of a potentially significant underlying mineralized system.
Importantly, previously unrecognized gold anomalism identified at West Gillham highlights the broader fertility of the system providing additional upside potential. With multiple high-confidence targets now defined across a meaningful strike extent, we are advancing rapidly toward a maiden drilling program, which we expect will be a key value inflection point for the Company.
Advancing Toward Drilling
Pantera is now progressing toward a maiden drilling program, with near-term activities focused on:
- Infill soil sampling and targeted rock sampling
- Detailed geological mapping
- Drill planning and target refinement
The Company is executing a U.S.-focused critical minerals strategy, positioning Gillham as a key asset within a broader portfolio of strategically located projects.
