About Dolly Varden

Dolly Varden Silver Corp. is a mineral exploration company focused on exploration in northwestern British Columbia. Dolly Varden has two projects, the namesake Dolly Varden silver property and the nearby Big Bulk copper-gold property. The Dolly Varden property is considered to be highly prospective for hosting high-grade precious metal deposits, since it comprises the same structural and stratigraphic setting that host numerous other high-grade deposits (Eskay Creek, Brucejack). The Big Bulk property is prospective for porphyry and skarn style copper and gold mineralization similar to other such deposits in the region (Red Mountain, KSM, Red Chris).

The current mineral resource estimate at Dolly Varden, effective date August 27, 2015, consists of four deposits with an Indicated Resource of 3.07 million tonnes grading 321.6 g/t Ag, for 31.8 million ounces of silver, plus an Inferred Resource of 0.9 million tonnes grading 373.3 g/t Ag, for 10.8 million ounces of silver. These resources were estimated at a cut-off grade of 150 g/t Ag. For more details, please refer to a NI 43-101 compliant Technical Report filed on www.sedar.com and on the Company's website.
