Pantera Minerals (ASX: PFE) has confirmed high-grade antimony and polymetallic mineralisation at its wholly-owned Gillham Project in southwest Arkansas, USA.
The company’s first-pass modern exploration has delivered promising results that validate the project’s potential and outline multiple priority drill targets.
The work represents the first modern exploration undertaken at Gillham, producing rock chip assays of up to 3.92 per cent antimony (Sb) alongside strong silver, lead, gold and base metal results.
Soil sampling has further reinforced the scale of the mineralised system, with peak values of 2,660 parts per million (ppm) antimony defining coherent anomalies extending approximately 500 metres in strike, supported by coincident arsenic, zinc and lead anomalism.
Initial assay results from across the project include standout values of 3.92% Sb, 0.47% Pb and 10.3 grams per tonne (g/t) Ag; 1.1% Sb, 1.32% Pb and 6 g/t Ag; 1.96% Cu, 1.465% Zn and 0.29% Pb; 4.79% Pb, 0.22% Cu and 20.5 g/t Ag; along with significant gold assays of 1.59 g/t Au and 0.47 g/t Au.
These results confirm the presence of high-grade mineralisation across several key prospects, including Stewart, Davis Mine and newly identified gold targets.
Crucially, no drilling has previously been undertaken at Gillham, indicating significant exploration upside for Pantera.
Geochemical programs have delineated two standout antimony anomalies along the Stewart–May trend, each extending between 400 and 500 metres within a broader mineralised corridor that exceeds two kilometres in strike.
These anomalies are supported by coincident rock chip mineralisation and remain largely untested, presenting compelling future drill targets.
Newly identified gold anomalism at the West Gillham area adds to the broader potential of the system, highlighting additional opportunities beyond antimony and base metals.
Pantera’s Executive Chairman and CEO, Barnaby Egerton-Warburton, said the early exploration success strongly validates the project’s potential.
“These initial results provide highly encouraging validation of the Gillham Project, with high-grade antimony in rock chips up to 3.92 per cent Sb directly associated with exceptional soil anomalies, up to 2,660ppm Sb,” he said.
“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 mineralised system.
“Importantly, previously unrecognised 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.”
Following the strong first-phase exploration, Pantera is advancing toward a maiden drilling program. Near-term activities will focus on infill soil sampling, targeted rock sampling, detailed geological mapping, and drill planning to refine high-priority targets.
The Gillham Project forms a core part of Pantera’s US-focused critical minerals strategy, with the company positioning the site as a key asset within its portfolio of strategically located projects aimed at supplying minerals essential to the energy transition and advanced manufacturing sectors.
