The Jan occurrence is located on the Jordan River, approximately 2 kilometres south west of the Elliott Reservoir.

The area is underlain by basalt of the Eocene Metchosin Volcanics and gabbroic and diabase intrusions related to the coeval Sooke Gabbro occur nearby. The basalt and gabbroic rocks are sheared, brecciated and altered. Granitic intrusions have formed large breccia zones with hornblendite and pegmatites intruding and filling the brecciated older rock.

Locally, two types of mineralization are reported:

1.) Pyrrhotite with lesser chalcopyrite and pyrite are reported to occur in shear zones, and pyrite and chalcopyrite are also present in quartz stringers (up to 10 centimetres wide). This mineralization occurs in "andesite", adjacent to a Tertiary intrusive (Geology, Exploration and Mining in British Columbia 1970, page 293).

2.) Pyrrhotite and magnetite are reported to be widespread in the shear zones and along gabbro contacts, and chalcopyrite and rare sphalerite occur with the iron minerals. Pentlandite and bornite occur in small amounts in the sulphides and some areas of pyrite also occur (Assessment Report 544).

In 1958, Rio Can. Ex. completed a program of geological mapping, soil sampling and a self potential geophysical survey on the area as the Bob and Conrod claims. In 1963, Mascan Exploration completed a program of geological mapping and geochemical sampling on the area as the EXT group. In 1970, Western Mines completed a induced polarization survey on the area as the Jan claim.
