The Buck Gulch property is situated approximately 22 kilometres northwest of the town of Dease Lake on the west side of the lake. Access to the claims is either via a four-wheel drive trail from the abandoned town of Laketon (vehicles must be ferried to Laketon) or via helicopter from the Dease Lake airport. The property is bounded on the east by Lyons Gulch, on the north by Dease Creek and extends west past Buck Gulch.

The Buck Gulch property is primarily underlain by a series of sedimentary and volcanic units of the Mississippian to Triassic Cache Creek Complex. Bedding generally has a westerly to northwesterly structural trend with gentle to moderate dips to the north-northeast.

Within the showing area, the Cache Creek Complex is commonly composed of chert, argillites and greywacke of the Late Triassic Kedahda Formation. These sediments overlie limestones and volcano-sedimentary rocks of the Permian Teslin and French Range formations. Occasional limestones of unknown age (Upper Mississippian) underlie the Teslin and French Range rocks. As well, a small listwanite body can be found on the eastern bank of Buck Gulch approximately 500 metres south of the confluence of Buck Gulch and Dease Creek. These listwanites are identified as Upper Mississippian, and are similar to those found on the north flank of Mount McLeod. Overlying the Cache Creek Complex are massive olivine basalt flows of the Upper Tertiary Tuya Formation, as well as thin to moderate (up to 15 metres) deposits of Pleistocene glacial and glaciofluvial debris. Sporadic quartz stringers are present in the sediments. These stringers are erratic in width (5 to 15 centimetres) and generally terminate quickly. Occasionally, these veins exhibit minor amounts of sulphide mineralization, but usually they are free of mineralization and appear to be sweat veins due to regional metamorphism.

A rock sample (30143R) taken from a 15 centimetre wide quartz vein mineralized with chalcopyrite and malachite stain analyzed 1462 parts per billion gold and 10,444 parts per million copper (Assessment Report 24493). The vein strikes 058 degrees and dips vertically and is located on the northwest bank of Buck Gulch approximately 400 metres south of the confluence of Buck Gulch and Dease Creek. The quartz vein appears to be discontinuous and pinch out in both directions.

In 1995, Hera Resources Inc. conducted a preliminary exploration program over the Buck Gulch property in an attempt to determine the source for placer gold known to occur in Dease Creek. As well, the project was conducted as a follow-up on four anomalous pan concentrate samples recovered in both Lyons and Buck Gulch by Active Minerals Ltd. in 1991. The program consisted of prospecting, rock and soil sampling, as well as silt and heavy mineral pan concentrate sampling. A total of 26 rock samples, 50 soil samples, 6 silt samples and 2 pan concentrates were collected.
