The Moonshine prospect is located on Crown grant Lot 1881, one kilometre south of the Davis Creek bridge on Highway 31, south of Lardeau, in the Slocan Mining Division.

Regionally, the area lies within the Kootenay Arc near the margins of the Ancestral North American Terrane. The Kootenay Arc is a curving belt of highly deformed metasedimentary and metavolcanic rocks which includes the Upper Proterozoic Horsethief Creek Group, the Eocambrian Hamill Group, the Lower Cambrian Badshot Formation, and the lower Paleozoic Lardeau Group. The volcano-sedimentary sequence is intruded by numerous Ordovician, Devonian and Mississippian granitoid plutons. The rocks have undergone regional metamorphism to middle or upper greenschist facies (Paper 1993-1).

The mineralization is hosted by grey and white crystalline limestone of the Lower Cambrian Badshot Formation which is overlain by brown micaceous quartzite of the Marsh Adams Formation of the Hamill Group and phyllite of the Index Formation of the Lardeau Group. The rocks strike northwest and dip 15 to 20 degrees southwest. The limestone forms steep bluffs above and south of the workings.

Massive galena, sphalerite and minor chalcopyrite occur with minor quartz in a narrow discontinuous fractures that strike northeast and dip 65 degrees northwest. The sulphides are present both as fillings of the fracture and as replacement of the limestone, near the base of the unit. Quartz is mainly along the footwall of the fracture. The mineralized fracture ranges in thickness from a few centimetres up to almost 2 metres. Lenses of coarse massive sulphides, up to 1.5 metres long and 30 centimetres, wide occur along the fracture and constitute the best ore.

Limited mining between 1951 and 1968 produced 188,868 grams of silver, 98,366 kilograms of zinc, 86,748 kilograms of lead, 437 kilograms of copper and 31 grams of gold from 573 tonnes milled.
