The Watson Bar (IV) occurrence is located in the southern head waters of Second Creek, a tributary of Watson Bar Creek, at an elevation of approximately 1300 metres.

A north-northwest trending splay of the Fraser fault system transects the property bringing Lower Cretaceous Jackass Mountain Group arkose, greywacke and minor siltstone, on the west, into contact with Eocene volcanic rocks, on the east. Sedimentary rocks are intruded by a granodiorite stock and feldspar porphyry dikes of Late Cretaceous to Early Tertiary age. A "quartz eye" porphyry dike may be considerably younger.

Locally, a broad area of silicification and argillic alteration in hosted by kaolinized and silicified sandstone and siltstones and minor smectite hosts gold values.

Six samples from the showing have yielded values from 0.2 to 2.2 grams per tonne gold (Assessment Report 31391).

The area has been explored in conjunction with the Watson Bar (MINFILE 092O 051) occurrence. In 1981, E&B Explorations completed a program of rock, soil and silt sampling on the area as the Carolyn 1 claim. In 1987, a program of geological mapping and silt and soil sampling was completed on the area as the Second claims. In 1988 through 1991, Cyprus Metals completed a program of geological mapping, rock and soil sampling and 20 diamond drill holes, totalling 3043.1 metres. During 1996 through 1998, Stirrup Creek Gold completed a program of trenching and diamond drilling (36 holes totalling 5998.5 metres) on the area. During 2004 through 2009, Durfield Geological completed programs of geological mapping, trenching, geochemical sampling, bulk sampling and an induced polarization survey.
