The Muse showing area is underlain by marine sedimentary and volcanic rocks of the Upper Triassic Stuhini Group, consisting of volcaniclastics, tuffs, tuffaceous breccias, argillites and minor limestone. These are intruded by several small structurally controlled stocks of hornblende diorite to augite porphyry of Triassic or possibly Jurassic age.

Strongly fractured and chloritized mafic volcanics with up to two per cent disseminated pyrite and chalcopyrite; associated with north trending shears; possible evidence of porphyry system. A 1992 grab sample assayed 0.32 per cent copper 0.9 gram per tonne silver and 0.025 gram per tonne gold (Open File 1993-1, Lithogeochemical Analyses table, sheet 2 of 3).

In 1984 and 1986, Sage Resources Ltd. conducted a geological-geochemical-geophysical reconnaissance program on their Oro Claims and Chevron Resources explored their Tan and SUN 1 claims. The Muse is located immediately east of the ORO 5 or ORO 6 claims, probably on the northern part of Chevron's SUN 1 claim (Assessment Reports 11820, 12628, 13840, 15894).

In 1992, a BC Geological Survey geological mapping project in the Tatsamenie and Bearskin lakes area resulted in an updated regional geological framework and the discovery of several new showings including the Muse.

In 2019, Brixton Metals Corporation expanded their Thorn property through staking and acquisition of claims including those covering the Muse showing. In 2020, Brixton Metals Corporation completed a program of geochemical (rock and soil) sampling, a 12.5 line-kilometre ground induced polarization survey, a 715 line-kilometre airborne magnetic and electromagnetic survey and 19 diamond drill holes, totalling 5292 metres, on the area of as part of the Thorn property. Drilling was performed on the Outlaw (MINFILE 104K 176) occurrence area. No work is reported on the Muse showing since discovery in 1992.

Refer to ORO (104K 039) and Golden Bear (104K 079), located about 5 kilometres north, for related area geological and work history information. Refer to Thorn (104K 031), Chivas (104K 180), East Outlaw (104K 083), Oban (104K 168), Trapper (Inlaw) (104K 078) and Metla (104K 161) for details of the work history of the greater Thorn property.
