PJX Resources Discovers a Third Large Target Area With Sullivan Style Sedex Deposit Potential on the Dewdney Trail Property In Southeastern British Columbia

PJX Resources has announced a significant exploration breakthrough with the identification of a third large Sedex-type deposit target on its Dewdney Trail Property in southeastern British Columbia. The Grundy Creek target joins two previously identified targets (Estella Basin and Lewis Ridge) in what appears to be forming a cluster of potential sedimentary exhalative deposits in the same geological framework as the historic Sullivan mine, located just 25 kilometers away.

The new target is characterized by compelling geological evidence including a historical adit containing strongly magnetic massive sulphide boulders that returned exceptional assays of 79.03 g/t silver and 7.39% lead, along with elevated cobalt, copper, and iron. The target is further defined by a 2-kilometer-long airborne magnetic anomaly and outcrops of black laminated calcareous muds anomalous in zinc, lead, manganese, and barium - geological signatures consistent with Sedex venting environments. Importantly, the target also displays coticule alteration in sediments, the same hydrothermal alteration style found at the Sullivan deposit.

The discovery carries significant sectoral implications as it suggests the potential for a cluster of stacked Sedex deposits similar to world-class mining districts such as Mt. Isa in Australia or Red Dog in Alaska. The Sullivan mine, which operated for over 90 years until 2001, produced more than 297 million ounces of silver, 8.4 million tonnes of lead, and 7.9 million tonnes of zinc, establishing it as one of the world's premier base metal deposits. PJX's consolidation of the largest land package (750 km²) in the Sullivan district positions the company to potentially unlock multiple deposits of similar scale.

Looking forward, PJX plans to continue drilling the Estella Basin target while advancing development of the Lewis Ridge and Grundy Creek areas in 2026. The company has also identified over 10 priority gold targets along the 65-kilometer Vulcan gold belt and intends to pursue strategic partnerships to maximize development opportunities. With three large Sedex targets now identified within the same productive geological corridor, PJX appears well-positioned to potentially recreate the geological conditions that made the Sullivan district one of Canada's most important base metal mining regions.
