The Six-Gun showing is located southeast of Mount Pereleshin. The area is underlain by the "Pereleshin Pluton" which is an Early Jurassic body of the Texas Creek Plutonic Suite, composed primarily monzodioritic to gabbroic intrusive rocks. Andesitic plagioclase-hornblende dikes and narrow aplite dikes of inferred Tertiary age (Paleocene to Eocene Sloko-Hyder Plutonic Suite) are abundant. The mafic dikes generally occur along steeply dipping, northwest trending faults. A Pennsylvanian to Lower Permian roof pendant of the Stikine Assemblage is exposed in the occurrence area. These rocks consist of a sedimentary sequence, made up of mainly limestone, meta-argillite, meta-siltstone, ash tuff and calcareous siltstone, and a volcanic sequence made up of foliated meta-volcanics, andesitic flows, volcaniclastics and tuffs.

At 960 metres elevation and adjacent to the main creek in the drainage area, a poorly exposed 4 to 8-metre wide zone of sheared, carbonate-altered, rusty-orange "granodiorite" occurs adjacent to a small (30 metre wide) gabbroic dike/plug. The shear is on strike with a fault exposed on the other (south) side of the valley. Weak malachite mineralization was noted in the shear. No other mineralization was observed. A sample (102919) of this material yielded 1.24 grams per tonne gold (Assessment Report 20704).

In 1990 the Mount Pereleshin property was explored by West Sea Development Corp., under option from Goldbelt Mines Inc. Besides conducting mapping and prospecting, West Sea collected 13 heavy mineral samples, 137 rock samples and 44 silt samples. A total of 47 mandays were spent on the property during the 1990 exploration program. There is no record of any other previous work that has been carried out in this claim area.
