A trench at the B showing exposes a shear zone in Cherry Creek unit diorite to monzonite of the Late Triassic-Early Jurassic Iron Mask batholith. The shear is pyritic and exhibits some clay alteration with epidote veining and contains chalcopyrite and malachite. A rock sample from the trench in 1983 analysed up to 2.0 per cent copper and 10 grams per tonne silver (Assessment Report 11838).

In 1972, Rolling Hills Copper Mines Ltd. conducted geological mapping on the B claims. In 1978, Cominco Ltd. drilled four vertical percussion-drill holes totalling 346 metres on the Wildrose 4 claim. Two of the holes were just south of the trench at the B showing and intersected traces of chalcopyrite in diorite. In 1983, Aberford Resources Ltd. conducted reconnnaissance geological mapping and rock geochemistry on the large IM claim group which covers the showing. In 1989, Cominco Ltd. drilled 41 percussion-drill holes totalling 3507 metres over their large holding of IM claims. Seven holes were located around the B showing area but none yielded mineralization. In 1989, Afton Operating Corporation conducted 8.4 kilometres of VLF-EM and ground magnetometer survey and took 189 soil samples on the Wildrose II claim which covers the B showing.
