VANCOUVER, Nov. 27, 2017 /CNW/ - Dolly Varden Silver Corporation (TSX.V: DV | U.S.: DOLLF) (the "Company" or "Dolly Varden") is pleased to announce results from the seventh batch of drill holes from the 2017 program on the Dolly Varden Silver Project in the Golden Triangle of northwestern British Columbia. This includes the discovery of an eastern fault-offset continuation of the Torbrit Deposit.
Hole DV17-076, drilled in the Torbrit East area, intercepted two zones, with the Upper Zone yielding a core length of 27.00 metres (22.64 m true thickness) grading Ag 119.7 g/t, Pb 0.57 % and Zn 0.53 % for a silver-equivalent of 171.6 g/t. Within this interval is 6.85 metres (5.74 m true thickness) grading Ag 298.5 g/t, Pb 1.06 % and Zn 0.80 % for a silver-equivalent of 385.2 g/t.
While the higher-grade interval is being presented above, there is a case to be made for a moderate-grade approach by combining the Upper and Lower Zones in hole DV17-076 as a single intercept. From 107.00 to 163.00 metres is a core length of 56.00 metres (46.97 m true thickness) grading Ag 82.7 g/t, Pb 0.43 % and Zn 0.42 % for a silver-equivalent of 122.9 g/t.
"Hole DV17-076 marks the third major new discovery of a mineralized zone during the 2017 exploration program. It highlights the great potential for expansion in this historic mining district," said Gary Cope, President and CEO of Dolly Varden.
The intercept in hole DV17-076 is of the Dolly Varden-Torbrit Horizon (DVTH) style of mineralization, with a jasper and sulphides rich Upper Zone and a smoky quartz and sulphides rich Lower Zone. The fault-offset block for Torbrit East is approximately 60 metres higher and 70 metres east of the edge of the Torbrit Mine workings and outside of the current resource block model.
In addition, the mineralized zone reported in hole DV17-074 represents the most northern intercept of the DVTH to date, which now extends the favourable exhalative horizon to over 850 metres northwest of DV17-076.

Note 1: Silver-Equivalent 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.
Note 2: For the Western Sector gold-copper zones, Gold-Equivalent Au-Eq = Au + (Cu%*22.046*Cu price*31.103/Au price) + (Ag*Ag price/Au price). Metal prices used for this formula: Au = $US 1,300/oz, Cu = $US 3.00/lb, Ag = $US 16.25/oz.
Note 3: No provisions have been made for relative metal recovery, thus 100% recovery is used for the silver-equivalent values.
