The Bob property covers several showings located approximately 400 metres east of the Duck Creek road, 800 metres north of its junction with the Creston-Kootenay Bay highway at Wynndel. The main showing is exposed in an adit at 730 metres elevation, but it is reported that this property was formerly known as the Elsie Holmes and that the old workings included another longer crosscut, the portal of which was approximately 250 metres southwest of the main adit. Hostrocks in the area are argillaceous quartzites mapped as Creston Formation, part of the Middle Proterozoic Purcell Supergroup, which are metamorphosed to regional greenschist grade (biotite facies).

The occurrence is a quartz-calcite vein with chalcopyrite and lesser amounts of galena and copper carbonates. Where exposed underground the vein strikes northeast, dips 45 degrees southeast, and has a width ranging from 0.3 to 1.2 metres. The vein was drifted on for 15 metres and raised on for 10 metres, with approximately 9 tonnes of ore being stockpiled.
