Excelsior Expands Footprint, Buster Trend Hits Big

Key Concepts

• Footprint Expansion: Increasing the known area of a mineral deposit through step-out drilling.
• Step-out Drilling: Drilling outside the boundaries of known mineralized zones to test for continuity and scale.
• Head Grade: The average grade of ore (measured in grams per ton, g/t) as it is mined and sent to the processing plant.
• Mineralized Halo: A lower-grade zone of mineralization surrounding a higher-grade core or feeder zone.
• Feeder Zones: Geological structures that acted as conduits for mineral-rich fluids, often resulting in higher-grade ore concentrations.

Exploration Results and Resource Expansion

The current drilling program is focused on expanding the known mineralized footprint. Recent results confirm the presence of significant mineralization in previously untested areas, specifically to the west.

• Key Drill Intercepts:
  • Western Expansion: 13 meters at 1.15 g/t, confirming the extension of the deposit into an area that had never been drilled before.
  • Surface Mineralization: 33 meters at 1.25 g/t starting from the surface, which is highlighted as an ideal starting point for potential mining operations.
• Scale and Geometry: The project is currently testing a 700-meter section of a larger 7-kilometer mineralized trend. The objective of the next phase of drilling is to extend the known footprint to 1.3 kilometers. Current ore intercepts are occurring between 100 and 180 meters below the surface.

Geological Context and Economic Viability

The deposit is characterized by a large-volume, low-grade system, which is highly favorable for bulk mining methods.

• Grade Comparison: The project exhibits a "halo" of mineralization ranging from 0.5 to 1.0 g/t surrounding higher-grade cores. This aligns with, or exceeds, the performance of other regional mines, which typically operate at head grades between 0.5 and 0.8 g/t.
• Economic Potential: The presence of high-grade "feeder zones" within the broader low-grade halo provides a significant "kick" to the overall drill results, enhancing the economic profile of the resource.

Strategic Outlook

The primary focus remains on establishing the scale of the deposit. By stepping out 100 meters to the west and continuing to define the 7-kilometer trend, the company aims to prove that the project is a large-volume, low-grade asset. The consistency of the results—specifically the ability to hit ore from the surface and at depth—supports the thesis that the project is highly amenable to low-grade, high-volume production techniques common in the region.

Conclusion

The drilling program is successfully validating the expansion of a large-scale mineralized system. With results consistently meeting or exceeding regional benchmarks (0.5–0.8 g/t), the project demonstrates strong potential for development. The combination of near-surface mineralization and the discovery of high-grade feeder zones within a broader 7-kilometer trend suggests a robust, long-life mining opportunity that is currently being systematically defined through aggressive step-out drilling.
