The PAN showing is located in the upper reaches of the Trepanier Creek gorge, approximately 24 kilometres northwest of Peachland.

The property is underlain by porphyritic quartz diorite of the Early Jurassic Pennask Batholith, locally known as the Brenda stock.

Sulphide mineralization on the PAN showing is structurally controlled, and is found as fracture-coatings and vein-fillings in flat joints and northwest- trending vertical fractures. The area of mineralization is characterized by a greater abundance of veins and fracture-fillings accompanied by rock alteration. These consist of pyrite-epidote, secondary biotite, chlorite, and quartz veins. The veins are often accompanied by K-feldspar alteration selvages, and chlorite-sericite alteration of the host is common. There is no apparent zonation to the hydrothermal alteration, nor is there a pyrite halo. Molybdenite was noted in one location at the main PAN showing. Numerous chalcopyrite-pyrite exposures exist in the Trepanier Creek gorge for approximately 1 kilometre downstream from the main PAN showing. These exposures are included in the PAN occurrence.

In 1967, Lakeland Base Metals completed a program of soil sampling on the area as the JO claims. Canadian Superior Exploration Ltd. explored the property in 1969 and carried out a soil sampling program northeast of the gorge. Noranda Exploration Company Ltd. explored this general area during the 1960s; however, it is not recorded if work was carried out in the Trepanier Creek gorge. In 1970, Arrow Inter-America completed an airborne magnetic survey, totalling 752 line-kilometres, on the area as the Tic and Toc claims. During 1974 through 1976, Canadian Occidental Petroleum Ltd. explored the gorge and adjacent area to the east with programs of geological mapping, rock and soil geochemistry, and a magnetometer survey. They found that soil geochemical anomalies coincided with known mineralization; likewise, stream sediment anomalies were found draining areas of known mineralization, especially on the west side of Trepanier Creek. The magnetometer survey was inconclusive. During 2006 through 2012, Bitterroot Resources completed programs of rock, silt and soil sampling, geological mapping, 147.6 line-kilometres of ground magnetic surveys and a 66.2 line-kilometre ground induced polarization survey on the area as the North Brenda property.
