The Rainy occurrence is located on a south west slope of Chikamin Mountain, approximately 5 kilometres south-southeast of Zinc Bay on the Nechako Reservoir.

The area is underlain by Mt. Ney volcanic rocks of the Lower Cretaceous Skeena Group and undivided sedimentary rocks of the Middle Jurassic Smithers Formation (Hazelton Group). These have been intruded by intrusive rocks of the Eocene Coast Plutonic Complex(?) to the northeast.

Mineralization is associated with two shear zones in fine and coarse tuffs. An 8.0 metre long adit known as the California adit, along with several open-cuts, expose the main zone for a strike length of 15.0 metres. This main zone has an attitude of 160/70 degrees southwest and carries two quartz stringers with widths of 2.5 centimetres and 15 centimetres. Mineralization consists of pyrite, galena, sphalerite and arsenopyrite. Another shear zone at 040 degrees/ 90 degrees contains galena and arsenopyrite mineralization.

In 2006, Christopher James Gold, on the behalf of Guardsmen Resources, prospected the area as the Zinc Bay property. In 2011, Jet Gold, on behalf of Guardsmen Resources, completed a program of rock sampling and airborne magnetic and electromagnetic surveys, totalling 476 kilometres on the area. The Rainy occurrence area was covered by this survey.

Guardsmen resources relocated the Rainy adit in 2012. The narrow adit was reported to have completely caved in and covered by sloughing talus and scree of rusty weathering siltstone and argillite mapped as Middle Jurassic Ashman Formation (Bowser Lake Group). No vein outcrop was observed. The main excavation appeared to have followed a north-northwest trend. Representative samples of polymetallic vein mineralization were collected from the small dump below the caved adit. Samples consisted of banded, coarse-grained galena-sphalerite-pyrite-arsenopyrite plus/minus chalcopyrite in a gangue of coarse-grained subhedral to euhedral comb quartz. One grab sample (#1451) of a 13 centimetres wide vein graded 7.90 grams per tonne gold, 1078 grams per tonne silver, less than 1 per cent arsenic, less than 1 per cent lead, less than 1 per cent zinc and 0.048 per cent copper (Assessment Report 34099).
