The GV occurrence is located near the headwaters of Seattle Jack Creek, about 14 kilometres southeast of the community of Atlin.

The area is underlain by Mississippian to Triassic Kedahda Formation volcanics and sediments of the Cache Creek Complex. These consist of andesite, limestone, chert and pyritic argillite with quartz-filled fractures. These host listwanite altered ultramafic bodies and a felsic body termed "rhyolite" by Claymore Resources Ltd. (ca. 1984). The ultramafic rocks are spatially related to the upper Mississippian to Permian Nakina Formation (Cache Creek Complex) and possibly genetically related as well (Monger, Geological Survey of Canada Paper 74-47).

At the showing, gold mineralization is associated with the "rhyolite" and adjacent argillites. The "rhyolite" contains quartz-filled fractures that show no visible sulphides. Gold values are highest where these veins are most dense. The overall pyrite content of this rock is less than 1 per cent. In 1984, the best assay came from a drillhole set up on the "rhyolite" where a 3.05-metre section assayed 9.39 grams per tonne gold (Assessment Report 13269). Sporadic gold/silver values were also obtained from the listwanites.

In 1982-83, a regional reconnaissance program was followed up with further exploration on selected GV claims. In 1984, Claymore Resources Ltd. conducted an exploration program which consisted of 58 line kilometres of survey control grid, 1432 soil samples, 55 line kilometres of VLF-EM survey, 5 kilometres of road construction, two trenches, geological mapping, and 600 metres of NQ-size diamond drilling in 16 holes.

In 2006, Prize Mining Corp. conducted a small exploration program that included collection of 679 soil geochemical samples.

In 2018-19, Brixton Metals Corporation carried out exploration on their Atlin Gold Project which included: a 1992 line kilometre, helicopter-borne high-resolution aeromagnetic geophysical survey over a 40 square kilometre area that hosts the historic Pictou (104N 044) and Imperial (104N 008) showings, as well as the Yellowjacket gold mine (104N 043); the collection of 1227 soil samples, 110 rock samples and 1 stream silt sample; and a 1599.24 metre, shallow diamond drilling program that included 4 NQ-sized holes drilled at the Pictou showing and 18 NQ-sized holes drilled at the LD showing (104N 098, 100). In 2019, diamond drilling, as well as rock, soil and stream sampling focussed on historic areas known to host orogenic gold mineralization, as well as the Fourth of July batholith, Union and Sentinel mountains and Spruce Creek.
