DV Dolly Varden Silver Corporation

VANCOUVER, BC, Dec. 20, 2021 /CNW/ - Dolly Varden Silver Corporation ("Dolly Varden" or the "Company") (TSXV: DV) (OTC: DOLLF), is pleased to announce drill results from regional exploration and reconnaissance drilling at its 100%-owned Dolly Varden Project located near tidewater in northwestern British Columbia, with particularly encouraging results from the Wolf Vein, as well as the identification of large, new porphyry related copper-gold system.

At the Wolf Deposit, drill hole DV21-273 tested the southwest projection of the Wolf Vein, 94m down plunge from the current Mineral Resources, intersecting 1,532 g/t Ag, 0.44 g/t Au, 2.11 % Pb and 1.07% Zn over 1.22m core length within a brecciated sulphide-rich quartz vein hosted within a broader pyrite stockwork breccia zone of 17.50m averaging 214 g/t Ag and 0.47% Pb. The current NI 43-101 Mineral Resource Estimate hosts 3.83 million ounces of silver at 296 g/t in the Indicated category at Wolf. It is located approximately two kilometers northwest of the 25.0 million ounces of silver in the Indicated Category and additional 10.5 million ounces of silver in the Inferred category at Dolly Varden's Torbrit Deposit.

In other regional exploration drilling, Dolly Varden's technical team is highly encouraged by long intervals of stockwork quartz with strongly anomalous gold (>100 ppb) over wide intervals (up to 303 meters) along with silver and copper at the Western Gold Belt Area.  Hosted within early Jurassic volcanic rocks, this style of stockwork and alteration is analogous to numerous alkalic gold-copper deposits and mines in British Columbia.  The Company plans appropriate geophysical surveys for porphyry-style mineralization and subsequent follow-up drilling in this area.

"This high-grade silver intercept at Wolf demonstrates the excellent exploration and resource expansion potential on the Property. The next phase of exploration drilling will prioritize connecting our historic mines and current deposits of the Dolly Varden Trend with the deposits at Homestake 5.4km to the northwest along the Kitsault Valley Trend that comprise the recently announced proposed acquisition from Fury Gold Mines," said Shawn Khunkhun, CEO of Dolly Varden Silver. "Additionally, the strong indicator of porphyry related gold-copper-silver style indicators potentially the most significant exploration breakthrough on the Property in years".

A total of 10,506m in 31 diamond drill holes were completed at Dolly Varden during the 2021 field season. Results have been received for 10 holes that tested five regional exploration targets on the Property including the Wolf Vein extension and Western Gold-Copper Belt. Assays will be announced in the near future for the 21 holes completed at the high-grade Torbrit and Kitsol Silver Deposits.  The 21 near-Resource holes were drilled as part of a two phase program with the objective of expanding Resources as well as upgrading current Inferred Resources to Measured and Indicated Classification.

The 2021 drilling at Dolly Varden initiated the Company's two-year strategy to aggressively expand and upgrade the Torbrit Silver Deposit and multiple satellite zones with the objective of advancing Dolly Varden to be the next high-grade silver mine in British Columbia.

Hole DV21-273 is also significant as it tested the prospective Hazelton volcanic rock that underlies the sedimentary units of the Upper Hazelton for the Wolf Vein extension. Discovering that the strong potassic alteration associated with silver mineralization within the volcanogenic Torbrit Deposit continues beneath the sediment suggests that the mineralizing system continues to the west of the 4.5 km long surface alteration anomaly.  This opens up exploration potential of the entire bottom of the Kitsault valley north of Wolf towards the Property boundary and onto Homestake Ridge.

 "Intercepting silver mineralization associated with potassic alteration in the older volcanic rocks underneath the sediment package within the fold axis of a regional syncline gives our team further reason to drill test several geophysical anomalies identified along the northerly trend towards the deposits at Homestake Ridge", explained Rob van Egmond, Chief Geologist for Dolly Varden Silver.

Wolf is the northernmost deposit that comprises the current Mineral Resources at the Dolly Varden Project. Modelling of the epithermal vein style deposit indicates a stepped vein system, offset by steep faults. The hanging wall of the deposit has strong barium signature and the veins contain barite and quartz.  There are historic underground drifts at Wolf but no historic production was reported.

Western Gold-Copper Belt

On the Western side of the Kitsault Valley, three holes (DV21-267, 268 and 269) tested the Red Point target with structures related to a gold in soil anomaly within the southern end of the Western Gold belt quartz, sericite, pyrite (QSP) alteration zone. Drilling intercepted wide zones of stockwork veins with strongly anomalous gold, silver and copper mineralization within Hazelton volcanic rocks.  Proximal to intrusive rocks, this wide zone mineralization is analogous to other alkalic copper-gold porphyry related systems in British Columbia.  In the Golden Triangle, these deposits include KSM, Treaty Creek, Saddle (GT Gold), Red Chris and Snowfield.

This Western Gold Belt is located on the west side of the Kitsault valley and trends from near the Dolly Varden Mine northward for several kilometers towards Homestake Ridge. Intrusive-related QSP alteration is associated with zones of increased silica stockwork and multi-phased breccias with pyritic matrix.  This style of alteration, mineralization and brecciation is also common at other higher grade deposits in the Golden Triangle, including Homestake Ridge and Ascot's past-producing Premier and Big Missouri mines, as well as Goliath Resource's recent discoveries west of Dolly Varden.  Results are as follows:

Medallion

Three holes were completed at the Medallion Prospect (DV21-264, 265 and 266) located at the southern end of the Project. Historic trenches and small adits explored narrow zones of veining within weakly altered volcanic rocks hosting silver, copper lead and zinc mineralization. No significant results were returned.

Syndicate

Diamond drill holes DV21-270 and 271 were drilled from the same setup as Medallion to test the Syndicate Target. A near-surface vein in DV21-270 returned 126 g/t Ag and 1.31 g/t Au over a core length of 1.10m.

Silver Horde

One drill hole tested the potassic alteration zone at Silver Horde, approximately 900m north of Wolf. It was collared in sediment cap rocks to test the volcanic units down plunge of previously encouraging drill results.  Hole DV21-272 intersected two zones where diffuse sheeted veinlets were found carrying dark silver sulphosalts.  The structure returned 9.0 meters core length averaging 126.7 g/t Ag within the volcanic host, plunging towards the axis of the valley syncline.

About Dolly Varden Silver Corporation

Dolly Varden Silver Corporation is a mineral exploration company focused on exploration in northwestern British Columbia. The Dolly Varden Project consists of the namesake Dolly Varden silver property that hosts a unique pure silver mineral resource as well as the nearby Big Bulk copper-gold porphyry property. The Dolly Varden Project 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).

Dolly Varden has recently entered into an agreement with Fury Gold Mines to acquire the Homestake Ridge Project adjacent to the current Dolly Varden property to consolidate the Kitsault Valley Gold-Silver mineralization trend into one large, high-grade precious metals project with further exploration upside potential. 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).
