Dolly Varden Silver Corporation (TSX-V:DV) (OTCBB:DOLLF) is pleased to announce the results of the sixth and final batch of 13 drill holes from the 2018 diamond drilling program. In total, this year’s program consisted of 29,108 metres in 84 drill holes. The Dolly Varden Silver Property is in “The Golden Triangle” of northwestern British Columbia, Canada.
In the Torbrit Mine Area, hole DV18-163 yielded 75.45 metres (65.34 m estimated true thickness) grading Ag 418.9 g/t, Pb 0.28 % and Zn 0.14 %, for a silver-equivalent of 439.1 g/t. Within this intercept are 16.00 metres (13.86 m estimated true thickness) grading Ag 1,240.4 g/t, Pb 0.29 % and Zn 0.16 %, for a silver-equivalent of 1,262.2 g/t.
Also in the Torbrit Mine Area, hole DV18-164 yielded 75.80 metres (53.60 m estimated true thickness) grading Ag 155.2 g/t, Pb 0.63 % and Zn 0.32 %, for a silver-equivalent of 201.3 g/t. Within this intercept are 27.80 metres (19.66 m estimated true thickness) grading Ag 301.3 g/t, Pb 0.30 % and Zn 0.18 %, for a silver-equivalent of 324.9 g/t.
Gary Cope, President & CEO, says; “The high-grade and thick silver intercepts in the Torbrit Mine Area fill in a portion of the Torbrit deposit not previously drilled. They confirm the multi horizon zones and high-grade nature of this style of mineralization. In viewing the Dolly Varden Property as a whole, it should be noted that there are multiple silver deposits and high-grade silver targets within a 5 kilometre radius.”
The Musketeer exploration holes have been recorded in a separate table from the Torbrit and Dolly Varden Mines area. The Musketeer area is located approximately 2.5 km north of the Torbrit Mine along the same structural/alteration corridor.

|Silver Equivalent (Ag-Eq) is based on long term metal prices of Ag=$16.00/oz, Pb=$1.08/lb and Zn=$1.25/lb. No provision has been made for relative metal recovery, so Ag-Eq values assume 100% recovery. Ag-Eq = Ag + (Pb%*22.046*Pbprice*31.103/Agprice) + (Zn%*22.046*Znprice*31.103/Agprice).|
A mineralized zone does not normally receive a name designation until several intercepts have pierced the same structure. The term “Unnamed” is used for intercepts of interest, but which have not yet been linked from hole to hole.
The 2018 drilling program is designed to focus on resource delineation and verification, particularly in the areas of the new discoveries from the 2017 exploration season (see news releases of August 29, November 27 and December 4, 2017). These include Torbrit North, Torbrit East and Moose-Lamb targets, as well as areas around the Torbrit and the Dolly Varden deposits. Drilling results from the 2018 program also were released in five earlier batches (see news releases of August 12, September 6, October 11, November 19, and December 6, 2018).
The Torbrit North and Torbrit East discoveries are of the exhalative-style of silver and base metal mineralization along the Dolly Varden – Torbrit Horizon (“DVTH”), similar to the historic Torbrit Mine, but located in parallel and/or fault offset basins. The Torbrit North target is located 200 metres north and 220 metres deeper than the historic Torbrit Mine, in the footwall block northeast of the Moose-Lamb Fault. The Torbrit East target is located 70 metres east and 60 metres higher than the historic Torbrit Mine, in the hanging-wall block southwest of the Moose-Lamb Fault.
The Moose Lamb target discovery is an epithermal vein-style of mineralization and is similar to mineralization at the historic Dolly Varden Mine. It is adjacent to a major syn-basinal fault by the same name. The Kitsol Zone also shows similarities to the epithermal vein-style mineralization.
Exploration drilling was undertaken in the Potassic Alteration Belt – Musketeer Sector and in the pyrite-sericite alteration Goldbelt Sector on the western side of the valley.
Analytical testing was performed by ALS Canada Ltd. in Vancouver, British Columbia. Multi-element analyses was determined by Inductively–Coupled Plasma Mass Spectrometry (ICP-MS) for 48 elements following a 4-acid digestion process. High grade silver testing was determined by Fire Assay with either an atomic absorption, or a gravimetric finish, depending on grade range. A QA/QC procedure is maintained through the insertion of certified reference material geo-standards provided by CDN Resource Laboratories Ltd., as well as the insertion of blanks, in the sample stream.
Technical Information and Qualified Persons
Ben Whiting, P.Geo., Vice President of Exploration and Robert van Egmond, P.Geo., Chief Geologist for Dolly Varden, serve as ‘Qualified Persons’ as defined in NI 43-101, and have approved the scientific and technical information contained in this news release. To verify the technical information, both Qualified Persons have visited the project site on numerous occasions during the 2018 field season, with the latest site visit in October, 2018.
