The Harbey showing occurs in the headwaters of Reynard Creek, 6 kilometres northeast of Youbou. The Comego (092C 018) showing is 1.6 kilometres to west.

The area is within the Cowichan uplift comprising Paleozoic Sicker Group sedimentary and volcanic rocks. Triassic diabase and gabbro sills and dykes (informally Mount Hall gabbro), coeval with Karmutsen Formation (Vancouver Group) volcanics, occur in the area. Granodiorite and quartz diorite of the Early to Middle Jurassic Island Plutonic Suite intrude the rocks in the area.

Mineralization occurs in shear zones in pyritized, and/or hematitic chert, and in pyritized and silicified sheared diorite. The chert outcrops on the southern portion of the claim and is part of the Mississippian to Pennsylvanian Fourth Lake Formation (Buttle Lake Group). The intrusives have locally been kaolinitized, the chert has been silicified, and limonite staining was noted.

In 1986, the area was staked as the J.R. claims by Ruza Resources. In 1987, Sierra Madre completed a program of geochemical sampling and ground geophysical surveys. A sample across 1.2 metres of chert from a shear zone assayed 1.2 grams per tonne gold and 0.69 grams per tonne silver (Assessment Report 17125). A 0.61 metre sample of rusty, sheared diorite assayed 12.07 grams per tonne gold and 3.77 grams per tonne silver (Assessment Report 17125).

In 1989, Wellington-Young Resources completed a program soil sampling.
