PJX Resources Identifies Major Sedex Mineralizing Zone at Dewdney Trail Property in Legendary Sullivan Mining District

PJX Resources has unveiled a significant discovery in Southern British Columbia that mirrors the geological characteristics of the famous Sullivan deposit. Recent drilling campaigns on the Dewdney Trail Property have uncovered a 63-meter thick Quake zone containing pervasive mineralization with zinc, lead, silver and critical metals distributed consistently throughout the interval.

The Core Discovery: What Makes This Find Special

The mineralization pattern observed at Dewdney Trail bears striking similarities to historic mining systems in the region. The Quake zone, which extends from 172.3 to 236.0 meters in borehole ND25-26, demonstrates persistent metal enrichment characteristic of large-scale venting environments on ancient seafloors. Bands of bedded sulphide mineralization sandwich the main zone, with tourmaline alteration zones appearing both above and within the structure—a textural signature seen at comparable Sedex deposits.

The thickness and continuous nature of this zone strongly suggest a mineralization system capable of producing economically significant deposits. At one drill location, silver values reached 14.67 parts per million over 0.5 meters, with lead and zinc consistently elevated throughout the intersection. Copper and cobalt also appear distributed across the entire zone, indicating a polymetallic system.

Extending the Trend: Surface Evidence Strengthens the Case

Surface prospecting has discovered massive sulphide boulders 800 meters to the south along the same geological strike, suggesting the mineralization extends laterally across a substantial area. One boulder sample returned extraordinary assay results: 546 grams per ton of silver, 32.3% lead, and 4.89% zinc—grades that rival the historic Sullivan operation itself.

These boulder discoveries indicate that higher-grade bands exist within the broader mineralization system, though they haven’t been intersected by drilling yet. The current drilling penetrated younger syenite dykes that appear to mask deeper geology, explaining why the highest-grade zones remain at depth.

The Bigger Picture: Two Potential Venting Centers

The exploration model identifies not just one but potentially two separate mineralization environments within the property. North of the current drilling area, prospecting identified stacked tourmaline-altered beds over a 2-kilometer strike length. This region, designated the Lewis Ridge target zone, coincides with a large multi-element soil geochemical anomaly spanning zinc, lead, silver, copper, and gold.

This configuration parallels the Sullivan basin mineral system, where two major deposits (Sullivan and North Star) occur roughly 2 kilometers apart. The similarity in geometry, metal associations, and alteration patterns suggests PJX may have identified a comparable Sedex system with the potential to host multiple significant deposits.

Strategic Positioning and Market Implications

PJX Resources holds 100% of mineral rights across the 200-square-kilometer Dewdney Trail Property, positioned just 25 kilometers east of the Sullivan deposit near Cranbrook, British Columbia. The location offers exceptional infrastructure advantages: direct rail access to Teck’s Trail smelter, power availability, and road connectivity.

The proximity to established mining operations strengthens development feasibility. Glencore operates coal mining operations 60 kilometers to the east, while Hecla Mining’s metallurgical facilities lie approximately 4 hours south in Idaho. The planned Teck-Anglo American merger and existing Anglo American smelting capacity in the region further underscore the operational advantages of the Dewdney Trail location.

Polymetallic Appeal in a Rising Critical Metals Market

The mineralization suite identified at Dewdney Trail—particularly zinc, lead, lead, and silver—appeals directly to current market dynamics. With gold trading above $4,000 per ounce and industrial metals benefiting from energy transition demand, the combination of precious metals (silver) and base metals (zinc, lead) provides diversified commodity exposure.

Dave Pighin, consulting geologist for PJX with 60 years of exploration experience, noted that this represents the first discovery during his career of a mineralizing system comparable to the Sullivan basin. The discovery of thick, consistently mineralized zones with supporting high-grade surface samples indicates a system of substantial scale rather than isolated mineralization pockets.

The Development Path Forward

Drilling expansion plans include tests of the southern prospecting area following spring snowmelt, potentially commencing in May or June 2026. This systematic approach should clarify whether the 800-meter-distant boulders represent debris from a single high-grade band at depth or indicate continued mineralization extension.

Meanwhile, PJX maintains exploration rights over 750 square kilometers across the broader Vulcan gold belt in the Cranbrook region, with over 10 prioritized gold targets awaiting testing. The company’s strategy targets partnerships to accelerate drilling on the most prospective objectives, particularly as gold prices remain elevated and investor interest in critical mineral supply sources continues expanding.

The Dewdney Trail discovery demonstrates that the Sullivan district’s productive mineralization systems extended across a wider footprint than previously exploited, suggesting substantial untested deposit potential remains in the region.
