VANCOUVER, July 26, 2017 /CNW/ - Dolly Varden Silver Corporation (TSX.V: DV | U.S.: DOLLF) (the "Company" or "Dolly Varden") is pleased to announce results from the first four holes of the 2017 diamond drilling program on the Dolly Varden Silver Project in the Golden Triangle of northwestern British Columbia.
Hole DV17-039 yielded two mineralized intercepts. The Upper Zone consisted of a core length of 11.20 m (9.98 m true thickness) grading Ag 97.6 g/t, Pb 0.41 % and Zn 1.25 % for a silver-equivalent of 180.9 g/t. Within this Upper Zone interval is 1.95 m (1.74 m true thickness) grading Ag 182.6 g/t, Pb 1.05 % and Zn 1.66 % for a silver-equivalent of 314.5 g/t. The Lower Zone consisted of a core length of 15.00 m (12.72 m true thickness) grading Ag 172.4 g/t, Pb 0.69 % and Zn 0.81 % for a silver-equivalent of 244.4 g/t. Within this Lower Zone interval is 6.00 m (5.09 m true thickness) grading Ag 355.3 g/t, Pb 1.63 % and Zn 1.30 % for a silver-equivalent of 493.1 g/t.
The 2017 exploration program will consist of over 5,000 metres of diamond drilling in about 25 to 30 drill holes, with two-thirds allocated to resource validation and expansion and one-third allocated to reconnaissance drilling on targets beyond the current resource estimates. There are over 50 exploration targets on the property. Geological mapping, plus geophysical and geochemical surveys are also underway for both the main Dolly Varden Ag-Pb-Zn Project, as well as the adjacent Big Bulk Cu-Au Project.
"It is good to see the silver and base metal results coming in for the Torbrit Deposit. Previous resource estimates only focused on the silver grades and did not include value for the lead and zinc," said Gary Cope, President and CEO of Dolly Varden.

Note: Ag-Eq = Ag + (Pb%*22.046*Pb price*31.103/Ag price) + (Zn%*22.046*Zn price*31.103/Ag price). Metal prices used for this formula: Ag = $US 16.25/oz, Pb = $US 1.00/lb, Zn = $US 1.25/lb. No provisions have been made for relative metal recovery, thus 100% recovery is used for the silver-equivalent values.

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 a NI 43-101 compliant Technical Report filed on www.sedar.com and on the Company's website.
