The Ridge (H22) Creek occurrence is located 200 metres south of the west flowing Cotter Creek, at an elevation of approximately 80 metres.

The oldest rocks in the area are mapped as part of the Middle to Upper Paleozoic Sicker Group. The Sicker Group, however, is under-going redefinition in the Cowichan and Buttle Lake uplifts; a new Upper Paleozoic Buttle Lake Group has been created from what were mainly sediments from the upper part of the Sicker Group. See the H-W occurrence (MINFILE 092F 330) for a summary of revisions.

These rocks are bounded on the west by Herbert Inlet while on the north, south and east they are overlain by mafic to intermediate volcanics of the Upper Triassic Karmutsen Formation, (Vancouver Group). These volcanics are cut by andesitic dikes ranging from 0.1 to 10 metres in width. A small area of diorite belonging to the Early to Middle Jurassic Island Intrusions is exposed along the east side of Herbert Inlet.

Locally, east-west trending quartz-carbonate-pyrite veins are hosted by basalts and a carbonatized feldspar porphyry dike. The veins strike 90 degrees and dip 65 degrees north. In 1987, a sample (18413) assayed 0.89 gram per tonne gold (Assessment Report 16224). In 1988, a trench sample (18504) assayed 4.29 grams per tonne gold (Assessment Report 17728). Assays for silver, lead and zinc were reported to be locally anomalous.

In 1984, Consort Energy completed a program of prospecting and silt and soil sampling on the area as the Lazeo-Klein claims. This work identified a high order stream sediment gold anomaly in the area, with results up to 540 parts per billion gold (Assessment Report 12791). In 1985, a program of rock, silt and soil sampling was completed. Silt and soil samples identified anomalous values of gold in creeks to the southwest between Cotter Creek and Gibson Cove. In 1987 and 1988, programs of geological mapping; rock, silt and soil sampling; trenching and geophysical surveys were completed.
