The Dewdney 26 showing is located about 30 kilometres east-northeast of Kimberley and about 450 metres east of Lewis Creek.

The showing area is underlain by sedimentary rock of the Helikian Creston Formation, Purcell Supergroup. In 2014, prospecting was carried out in the Lewis Creek area by PJX Resources Inc. who collected 45 rock samples for analysis.

A mineralized quartz vein swarm occurs sub-parallel to bedding at the contact of a phyllite unit with a more massive silty quartzite. Depending on location, veins contain pyrite, galena, sericite, pink feldspar, iron carbonate (siderite?), goethite, hematite, and/or specularite. One vein host was described as an undulating argillaceous siltstone.

Analyses of samples DT23 to DT26 over 100 metres apart contained anomalous values in molybdenum, lead, zinc, silver, and gold. Sample DT26 graded 0.66 per cent lead, 0.14 per cent zinc, 0.025 per cent molybdenum, 53.3 grams per tonne silver, and 0.84 gram per tonne gold (Assessment Report 35582). The highest gold analysis was 1.22 grams per tonne gold from sample DT25.

In 2016 to 2022, PJX Resources Inc. conducted geological mapping, rock geochemistry sampling, airborne geophysics, and drilling on the Dewdney Trail Property (Assessment Reports 36649, 38859, 40906, 40908).
