The Dolly Varden property is located on the west side of Dolly Varden Mountain, 13 kilometres northeast of Slocan Lake. Access can be gained by bush road leading up the east side of Wilson Creek from the town of Rosebery at Slocan Lake. The last portion of the route is a footpath.
The showing consists of a persistent quartz vein (Assessment Report 9067) carrying disseminated pyrite and argentiferous tetrahedrite and minor stibnite and chalcopyrite. The vein strikes east, dipping 55 degrees north. It is 0.6 to 3.6 metres thick and has been traced for 600 metres. A four kilogram sample of material selected from the dump assayed 1.3 grams per tonne gold and 1596 grams per tonne silver; however, samples taken from the vein underground yielded low values (Assessment Report 9067). Although the vein crosscuts volcanic rock, it occurs within a bleached and rusty coloured alteration zone approximately 30 metres in thickness at the contact between andesitic volcanic rocks of the Permo-Triassic Kaslo Group and clastic sedimentary rocks (phyllite, argillite, quartzite and minor limestone) of the Triassic Slocan Group. A feldspar porphyry body of unknown age is shown (GSC Open File 432) in the area.
The first mention of the Dolly Varden claim was in the 1893 Minister of Mines Annual Report. The 1900 Minister of Mines Annual Report states that ore "high in silver values and with about $8.00 in gold per ton" was shipped from the Dolly Varden. The claim was Crown granted in 1901. Assessment Report 9067 reports that the old adit crosscut the mineralized zone for 18 metres and drifted for 15 metres along the vein. In 1982, 3900 metres of grid were established, geological mapping was completed, 72 soil samples were collected and analysed for copper and silver and three rock samples were assayed for gold and silver. In 1990, Black Tusk Explorations Limited (Assessment Report 20939) completed reconnaissance lithogeochemical sampling (40 samples analysed for gold, silver, copper and antimony), geological mapping and prospecting. In 1994, additional prospecting was undertaken (Assessment Report 23235).
