The Silver Queen occurrence is situated near the base of a cliff on the west face of Mount Slade, in the Golden Mining Division.

Regionally, the area is underlain by Proterozoic clastic sedimentary rocks of the Purcell and Windermere supergroups and by lower Paleozoic strata of the Beaverfoot and Mount Forster formations (Geoscience Map 1995-1).

The Purcell Supergroup strata include the Aldridge, Creston, Kitchener, Dutch Creek and Mount Nelson formations. The Windermere Supergroup unconformably overlies the Purcell Supergroup rocks and includes the Toby Formation and Horsethief Creek Group (Paper 1990-1).

In the vicinity of the occurrence, rocks of the Kitchener and Dutch Creek formations have been further subdivided and assigned to the Van Creek and Gateway formations. The Van Creek Formation correlates with the Lower Kitchener Formation while the Gateway Formation is equivalent to the lower portion of the Dutch Creek Formation. The Mount Nelson Formation has been subdivided into seven discrete members, a lower quartzite, a lower dolomite, a middle dolomite, a purple dolomite, an upper middle dolomite, an upper quartzite, and an upper dolomite (Open File 1990-26).

Rocks of the Horsethief Creek Group, Beaverfoot and Mount Forster formations are folded and overthrusted by rocks of the upper portion of the Dutch Creek Formation and the lower members of the Mount Nelson Formation. The sedimentary rocks have undergone regional metamorphism to at least greenschist facies.

The occurrence consists of a system of small veins hosted by the lower dolomite member of the Mount Nelson Formation. Near the occurrence, the sedimentary rocks strike northwest and dip steeply northeast. The underground workings consists of an adit driven on a vein about 20 centimetres wide that follows the lower contact of a northwest trending metadiabase dike. The mineralization comprises galena and sphalerite with minor chalcopyrite and pyrite. Chalcopyrite commonly occurs as intergrowths in sphalerite.

In 1961, 4.5 tonnes were mined from the property to produce 6936 grams of silver, 2329 kilograms of lead and 72 kilograms of zinc.
