The Silver Queen showing occurs on a tributary of the Stein River, east of the town of Lytton. The region is underlain mainly by plutonic rocks of the Jurassic to Tertiary Coast Plutonic Complex.

The showing consists of quartz veins within fractures zones which are probably related to northwest and northeast striking faults. The dominant rock types in the area are hornblende diorite and quartz monzonite which have been intruded by pegmatite and mafic dykes. Mineralization consists of pyrite, chalcopyrite, galena and sphalerite within both the quartz veins and wallrock. Hydrothermal alteration has resulted in extensive argillic, sericitic and potassic alteration of the rocks of the area.

Samples of mineralized vein material, taken in 1952, contained up to 1200 grams per tonne silver, 2.5 grams per tonne gold, 13.9 per cent lead and 5.9 per cent zinc (Malcolm, 1970 - Property File).
