The Pogo SE occurrence is located on the Cow 12 claim, which is situated on the ridge separating Chipman Creek to the north and the Chemainus River the south. The showing has been explored in conjunction with the Pogo (MINFILE 092C 074) occurrence.

The area is underlain by Mississippian to Pennsylvanian Fourth Lake Formation (Buttle Lake Group) cherty argillite and by Upper Devonian McLauglin Ridge Formation (Sicker Group) volcaniclastics. These rocks are intruded by granodiorite and quartz diorite of the Early to Middle Jurassic Island Plutonic Suite and Triassic gabbro (informally called the Mount Hall gabbro). Sulphide mineralization occurs in rusty shear zones as disseminations, and/or stringers along bedding, cleavage or crosscutting fractures. Mineralization is hosted in laminated sediments and volcaniclastics spatially associated with the gabbroic dikes. Pyrite and minor chalcopyrite are finely disseminated throughout the rocks.

Locally, gabbros and diorites host heavily oxidized zones with anomalous values in zinc, copper, lead and gold.

In 1964, E. M. Wilson staked the original Pogo 1-4 claims and completed a program of geological mapping, prospecting and geochemical sampling. A lone grab sample assayed 0.72 per cent zinc, 0.17 per cent lead and 0.13 per cent copper (Assessment Report 00566).

In 1985 through 1987, JBL Resources completed programs of geological mapping, prospecting, geochemical sampling, ground geophysical surveys and two diamond drill holes, totalling 99.5 metres, on the area as the Cow 12-16 claims. In 1986, a sample (4264) from the area assayed 0.49 gram per tonne gold (Assessment Report 16097).
