The region is underlain by (?)Hadrynian to Paleozoic Snowshoe Group rocks, which occur within the Barkerville Terrane of south-central British Columbia. These metasedimentary rocks consist primarily of marble, quartzite and phyllite which to the east of the Zone showing comprise the Downey succession (informal). Due to the imprecise location of the showing, it is not known whether it is the Downey succession or other Snowshoe Group successions which underlie the showing. Metamorphism of the region varies from chlorite grade to sillimanite and higher. The gold vein deposits of the region occur in rocks metamorphosed no higher than greenschist facies.
The showing consists of five subparallel and vertical quartz veins which occur in grey ankeritic schist. Ankerite-bearing rocks are common in the Downey succession and it is probable that these rocks are also part of this succession. The quartz veins strike at about 025 degrees, more or less corresponding with the strike of a major normal fault, the Antler Creek Fault, cutting the area. The veins are sparsely mineralized with arsenopyrite, pyrite and gold.
In 1996, geological mapping was conducted in a 3 square kilometre area on the western portion of the Nugget Mountain property; a total of 129 soil samples and 49 rock samples were collected. The Zone showing is located within a 1 kilometre radius of several showings (Gisco (093A 052), Pittman (093A 057)) that were explored along Antler Creek in the 1930s and 1940s, near the mouths of Nugget Gulch and Victorian Creek. In 1987, Rise Resources Inc. completed 419 kilometres of helicopter-borne magnetic and VLF-EM survey over their block of claims which covered the Zone showing. In 2005, a total of 43 samples (9 soil, 1 moss mat silt and 33 rock) were taken on the Nugget Mountain project claims, which covers the showing, on behalf of claim owners R.J. Menard and G.J. Newell.
