The G occurrence is located on the northeast slopes of Kaketsa Mountain, 750 metres west of the Hackett River, about 54 kilometres northwest of the community of Telegraph Creek.
The showing occurs near the contact of the Late Triassic Kaketsa pluton with Upper Triassic Stuhini Group volcanic and related sedimentary rocks. Pyrite with minor chalcopyrite is localized along shears/fractures in volcanic rocks.
The volcanic rocks are mainly porphyritic flows with lesser tuffs and tuffaceous siltstones. The flow rocks form massive units and are grey to dark green andesitic to basaltic porphyries with phenocrysts of augite and hornblende. The Kaketsa pluton is an elliptical intrusion 4 by 5.6 kilometres in diameter. Hornblende gave a K-Ar date of 218 +/- 8 million years (Geology, Exploration and Mining in British Columbia 1972, page 548). The core of the pluton is medium to coarse grained, equigranular quartz diorite or granodiorite.
During 1971, Skyline Explorations Ltd. conducted a detailed program of geologic mapping, sampling and ground magnetometer surveying. A total of 199 magnetometer readings were taken; 200 reconnaissance silt or soil samples were collected from around Kaketsa Mountain but several samples were lost in transit and only 135 results are available.
In 2013, Prosper Gold held the Star property which contained the G showing. In this year Prosper had a 1462 line-kilometre aeromagnetic survey flown which saw to the acquisition of high resolution magnetic and radiometric data over the entire Star property (Assessment Report 34836).
