PJX Resources discovers third large target area with Sullivan-style Sedex deposit potential on Dewdney Trail property, British Columbia

PJX Resources Inc. [TSXV: PJX] reported the identification of a third large target on the Dewdney Trail property with potential to host a Sedex type deposit similar to the world class Sullivan deposit, southeast British Columbia.

The presence of a potential cluster of stacked Sedex deposits in the Sullivan district has similarities to other major mining districts, such as the Mt. Isa district in Australia or the Red Dog district in Alaska. The historical Sullivan Sedex deposit is located only 25 km west of the cluster of Dewdney Trail targets. Cominco/Teck operated the Sullivan mine for over 90 years before closing in 2001. British Columbia Ministry of Mines reports the total Sullivan production at over 297 million ounces silver, 8.4 million tonnes lead, 7.9 million tonnes zinc as well as lesser quantities of gold, tin, copper, cadmium, antimony, and bismuth.

PJX’s initial two large Sedex targets identified by drilling and prospecting in recent years occur at the same geological horizon and are about 2 km apart. The two targets (Estella Basin area and Lewis Ridge area) are presented in PJX’s news release December 11, 2025. This new third additional target in the Grundy Creek area of the Dewdney Trail Property occurs at a separate slightly older geological horizon that is stratigraphically below the other 2 target areas.

The third target area is defined by a newly discovered, possibly pre-World War 1 or 2, adit with strongly magnetic massive sulphide boulders in the adit rock pile. The adit cannot be entered because rock material had been shoveled to block the entrance.

This historical adit occurs at the north end of an airborne survey strongly magnetic anomaly that is approximately 2 km in strike length.

Outcrops of black laminated calcareous muds that are anomalous in zinc, lead, manganese, and barium occur at the south end of the magnetic anomaly. The combination of this rock type with anomalous mineralisation is indicative of a venting environment and is often associated with Sedex deposits.

Outcrops with coticule alteration in sediments also occur at the south end of the magnetic anomaly. This style of hydrothermal alteration occurs at the Sullivan deposit.

Majority of the magnetic anomaly has limited to no outcrop rock exposure and covers a large area with potential to host a Sullivan size deposit.

John Keating, President of PJX commented: “We believe the mineralisation and deposit potential of the Dewdney Trail Property is exceptional with the discovery of 3 large target areas. We discovered Sullivan-style and grade boulders in the Estella Basin area only two years ago, and by late 2025, our drilling has already intersected a strongly mineralized system as evidenced by pervasive metal enrichment plumbing through a Quake zone with a true thickness of about 30 metres.

“Large plumbing systems like this support the potential to discover a significant deposit. We have now identified the 2 additional large targets in the Grundy Creek and Lewis Ridge areas. We plan to continue to drill to discover the deposit potential of the Estella target area while further developing and possibly drilling the Lewis Ridge and Grundy Creek target areas in 2026.”

PJX owns the mineral rights to the largest land package (750 km²) in the Sullivan mining district. The large land package has capacity to host multiple Sedex silver-lead-zinc deposits as well as gold deposits. The claims cover geology favourable to host multiple bedrock sources of the placer gold found in creeks along the 65 km long Vulcan gold belt.

PJX has already identified over 10 priority target areas with gold deposit potential that have not been tested and are mostly road accessible. PJX intends to provide further announcements regarding the gold potential and pursue strategic partnerships to maximize opportunities associated with these targets.

PJX has consolidated 100% of the mineral rights to the largest land package (750 km²) in the historical Sullivan Mine District and Vulcan Gold Belt near Cranbrook and Kimberley, British Columbia. PJX has developed a pipeline of more than 15 priority targets to be tested by PJX and/or companies interested in partnering to test often road accessible drill ready targets with gold, silver, copper, zinc and other critical metal deposit potential.
