Pantera Minerals Ltd
Pantera Minerals Limited (ASX: PFE, OTCQB: PTMLF) has announced breakthrough exploration results from its 100% owned Gillham Project in Arkansas, USA, with rock chip sampling returning outstanding Pantera Minerals antimony results up to 3.92% Sb alongside significant silver and base metal mineralisation. The first modern exploration program at the ~5,000-acre project has successfully validated the area's potential and accelerated progress toward a maiden drilling campaign.
The comprehensive sampling program combined 46 rock chip samples with 1,411 soil samples across five priority target areas, delivering coherent geochemical anomalies that define multiple high-confidence drill targets across a meaningful strike extent.
Key Exploration Highlights Define Multiple High-Priority Targets
The exploration program has delivered exceptional results across multiple prospects, validating the project's district-scale potential. Furthermore, these results demonstrate the systematic approach Pantera has taken to advance the Gillham Project.
Stewart Prospect – Priority Drill Target
The Stewart Prospect has emerged as the highest priority target with exceptional grades including 3.92% Sb, 10.3g/t Ag, 0.47% Pb (Sample GR008) and 1.1% Sb, 6g/t Ag, 1.32% Pb (Sample GR009). Historical production of approximately 1,000 tonnes of stibnite confirms established antimony endowment at this location.
Davis Mine – Largest Historical Operation
The Davis Mine area has returned impressive base metal results including 1.96% Cu, 1.465% Zn, 0.29% Pb (Sample GR019) and 4.79% Pb, 0.22% Cu, 20.5g/t Ag (Sample GR041). The extensive underground development demonstrates favourable geological structures for continued exploration.
Newly Identified Gold Prospects
In addition to the antimony discoveries, the program has identified new gold prospects. The Andrews Gold Prospect returned 1.59g/t Au (GR021) and 0.47g/t Au (GR016), whilst the South-east Davis area shows multiple anomalous gold values up to 0.16g/t Au.
| Prospect Area | Best Result | Significance |
|---|---|---|
| Stewart Mine | 3.92% Sb, 10.3g/t Ag | Historical producer, priority drill target |
| Davis Mine | 4.79% Pb, 20.5g/t Ag | Largest operation, extensive development |
| Andrews Gold | 1.59g/t Au | New discovery, unrecognised historically |
| Antimony Bluff | 0.85% Sb | Additional antimony mineralisation |

What Makes These Soil Anomalies Significant?
The soil sampling program has defined remarkable geochemical anomalies that highlight the scale and continuity of the mineralised system. Peak soil results include 2,660ppm Antimony (Sb), representing an exceptional soil anomaly alongside 1,245ppm Lead (Pb) and 680ppm Zinc (Zn).
Coherent Target Definition
The program has identified two distinct antimony anomalies with 400m and 500m strike lengths. Moreover, coincident arsenic (+30ppm), lead (+80ppm), and zinc (+80ppm) anomalism confirms a multi-element system.
A broader +1ppm Sb trend extends over 2,000m along strike, indicating the potential scale of the mineralised system. However, the eastern high-grade soil anomaly remains completely untested by mapping or rock sampling, representing a high-priority follow-up target.
Understanding Antimony: A Critical Strategic Metal
Stibnite is the primary ore mineral of antimony, typically occurring as silver-grey metallic crystals in structural vein systems containing quartz. At Gillham, stibnite mineralisation is hosted within structurally controlled quartz veins along fold hinges and fault zones.
These geological structures occur in sedimentary rocks dating from approximately 300-400 million years ago. For instance, this geological setting is typical of antimony deposits in the Ouachita Mountains region.
Strategic Importance for Investors
For investors, antimony represents a critical strategic metal with limited global supply sources. The metal is essential for flame retardants, batteries, semiconductors, and military applications.
With China dominating global production and increasing supply security concerns, projects like Gillham carry strategic significance. The high-grade Pantera Minerals antimony results at Stewart compare favourably with historical producing mines globally.
Furthermore, the multi-element nature of the system provides additional value streams and economic resilience through antimony-silver-lead-zinc-copper-gold mineralisation.
Strategic Pathway to Drilling Campaign
Pantera is executing a systematic approach to advance Gillham toward its maiden drilling program. The company has outlined clear immediate next steps and priority targets.
Immediate Next Steps Include:
- Infill soil sampling and targeted rock sampling to refine existing anomalies
- Detailed geological mapping to optimise drill hole positioning
- Drill planning and permitting for priority targets
- Assessment of additional U.S.-based critical mineral opportunities
Priority Drill Targets Identified
The Stewart Prospect represents the highest priority with high-grade antimony and a 500m strike anomaly. Additionally, the eastern anomaly remains an untested soil anomaly with exceptional Sb values.
The Davis Mine area offers historical production context with base metal potential, whilst the Andrews Gold Prospect requires follow-up as a new gold discovery.
Executive Chairman Barnaby Egerton-Warburton 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 2,660ppm 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 mineralised system."
Investment Thesis: Critical Minerals in a Strategic Location
Pantera Minerals has established itself as a focused critical minerals explorer with strategic positioning in the United States. The Gillham Project represents several compelling investment advantages.
Strategic Location Benefits
The project benefits from its U.S.-based critical mineral asset status in a mining-friendly jurisdiction. Located in Southwest Arkansas, the area has established mining history and infrastructure support.
Importantly, there has been no previous modern exploration despite historical production evidence. The 5,000-acre land position provides district-scale exploration potential for systematic development.
Technical Validation Points
The first modern exploration program confirms and upgrades historical results successfully. Multiple commodity streams enhance project economics through Sb-Ag-Pb-Zn-Cu-Au mineralisation.
Coherent geochemical anomalies support a systematic drilling approach, whilst historical production data provides geological confidence for future development.
Near-term Catalysts
The maiden drilling program is expected to be a key value inflection point for shareholders. Multiple high-confidence targets are defined across meaningful strike extent.
The systematic exploration approach maximises discovery potential, whilst additional U.S. opportunities support building a diversified critical minerals portfolio.
