Dolly Varden's Big Bulk Project Will Be Flown for a ZTEM Geophysical Survey in Conjunction With Hecla's Kinskuch Project

VANCOUVER, BC--(Marketwired - March 27, 2017) - Dolly Varden Silver Corporation(TSX VENTURE: DV)(OTC PINK: DOLLF) (the "Company" or "Dolly Varden") is pleased to announce that they will be participating in an airborne ZTEM geophysical survey in conjunction with Hecla Mining Company (NYSE: HL) ("Hecla"). The survey will cover Dolly Varden's Big Bulk Project and Hecla's Kinskuch Project in northwestern British Columbia, Canada. Hecla will serve as operator for the geophysical survey, which will be conducted by Geotech Ltd.

Geotech Ltd utilizes a helicopter-borne ZTEM (Z-Axis Tipper Electromagnetic) system, which detects the natural, or passive, fields of the Earth as a source of transmitting energy. Differences in the vertical component of the EM field are attributed to conductivity contrasts in the Earth's crust. Sulphide mineralization is particularly well suited as a target for EM studies. The Big Bulk Project is a copper-gold porphyry prospect.

The survey is expected to be conducted in late April or early May 2017. Costs will be apportioned according to line-kilometres flown over the respective properties.

"Cooperative effort between companies working in a region is a good way to keep exploration costs down while still achieving the exploration goals," said Gary Cope, President and CEO of Dolly Varden.

About Dolly Varden

Dolly Varden Silver Corporation 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, on-trend, 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 an NI 43-101 compliant Technical Report filed on www.sedar.com and on the Company's website.
