VANCOUVER, BC, Jan. 31, 2022 /PRNewswire/ - Dolly Varden Silver Corporation ("Dolly Varden" or the "Company") (TSXV: DV) (OTC: DOLLF), is pleased to announce drill results from the 2021 program at the Torbrit Silver deposit at the Dolly Varden Project.  The purpose of this program was to upgrade Inferred Mineral Resources and to step-out from the multiple Zones that comprise the Torbrit Deposit, the largest of the four deposits that comprise the Mineral Resources on the Property. 

Silver mineralization was encountered in most areas tested, usually with significant accessory zinc and lead values and commonly over widths suggesting potential amenably to bulk underground mining. Highlights include:

• DV21-274: 12.28m true width averaging 354 g/t Ag at Kitsol
• DV21-275: 18.27m true width averaging 230 g/t Ag at Kitsol
• DV21-275: 0.70m drilled length averaging 1,220 g/t Ag at Torbrit North Zone
• DV21-277: 16.00m drilled length averaging 212 g/t Ag (incl. 4.70m of 507g/t Ag) at Torbrit
• DV21-278: 5.10m drilled length averaging 364 g/t Ag at Torbrit Main

"Multiple holes intersecting over 4000 gram-meters of silver over wide intervals within the Kitsol epithermal vein is certainly encouraging, and the identification of wide intervals of syngenetic mineralization that connects the main Torbrit Deposit with the lesser drilled North Star Deposit to the west is also very significant.  The next phase of drilling to commence this spring will include targetting high-grade silver shoots within this wide horizon, as well as step-outs to the north and south at Kitsol," said Rob Van Egmond, Chief Geologist for Dolly Varden.

"These results, as well as the previously released extension of the high grade silver mineralization at the Wolf deposit demonstrate the continued resource expansion potential within the two kilometer long gap between the known deposits on Dolly Varden property. These intercepts corroborate our geological and geochemical modelling suggesting that the continuity of the prospective mineralized horizon between our historic mines and current deposits of the Dolly Varden Project, but also within the 5.4 kilometer-long unexplored area trending towards the gold and silver deposits at Homestake Ridge," said Shawn Khunkhun, CEO of Dolly Varden Silver. "Additionally, the proposed acquisition of the Homestake Ridge deposits will consolidate this significant trend for the first time in the +110 year mining history of the Golden Triangle".

A total of 10,506m in 31 diamond drill holes were completed at Dolly Varden during the 2021 field season of which 6,838m in 21 holes tested the high-grade Torbrit Silver Deposit (including Kitsol).  The 21 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. Results for the 10 holes that tested five regional exploration targets on the Property including the Wolf Vein extension and Western Gold-Copper Belt have been previously released (see December 20, 2021 news release).

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. 

Kitsol and Torbrit Extension Drilling

At the Kitsol vein, a three hole fan was completed to expand, infill and upgrade mineralization intersected wide intervals of epithermal-vein style mineralization. Additionally, these holes tested the northward extension of the Torbrit horizon at depth and to the east of Kitsol. Drill hole DV21-274 intersected 705 g/t Ag, 0.65% Pb and 0.28% Zn over 3.70m (2.97 true width) within a wider interval of 15.28m (12.28m true width) grading 354 g/t Ag, 0.38% Pb and 0.48% Zn in the epithermal Kitsol vein between 134.85m and 150.13m. 

Drill hole DV21-275 had a wide interval through the Kitsol vein averaging 220 g/t Ag, 0.79% Pb and 0.49% Zn over 23.88m (18.27 true width) as well as through the down plunge step-out from the Torbrit North Resource, intersecting 1,220 g/t Ag over 0.70m core length at 362.05m to 362.75m depth.  Of interest in hole DV21-275 was a 2m interval of core grading 5.4 g/t Au from 204m to 206m depth and could be an important vector during 2022 resource expansion drilling at Kitsol and towards the Western Gold belt trending to Homestake Ridge.

Mineralization along the northward projection of the Torbrit horizon was encountered in all three holes below the Kitsol Vein and confirms a synform of the Hazelton volcanic rocks that host the signature volcanogenic-related elevated potassic alteration under the center of the valley. Of significant importance is the presence of high grade silver mineralization along the horizon outside of the current resource.

Torbrit Western Connection to North Star

Wide intervals of stratabound debris-style volcanogenic-related mineralization (syngenetic) was discovered in a previously unknown northwest plunging extension of the Torbrit horizon to the west of the main Resource. Silver mineralization is associated with lead and zinc locally within the horizon in ratios similar to the North Star deposit. North Star is one of the four deposits that make up the Dolly Varden Mineral Resource Estimate with 1.99M oz Ag at an average grade of 263 g/t Ag in the Indicated and 35Koz Ag grading 224 g/t Ag in the Inferred category.

Three step-out drill holes (DV21-255, 256 and 257) identified the horizon. DV21-256 intercepted a zone averaging 262 g/t Ag, 0.28% Pb and 0.43% Zn over a 3.00m core length. Also noted in the results is gold and copper mineralization in association with the horizon but as more epithermal style as seen on the western gold belt leading north to the Homestake deposits. In drill hole DV21-255 a 0.95m interval graded 1.23% Cu and 0.39g/t Au within a section of epithermal crosscutting mineralization.

Torbrit Main and Torbrit North offset Infill and expansion Drilling

The objective of the 2021 near resource drilling was to test the extents of the mineralized lenses within the Torbrit Resource area in areas that had relatively widely spaced resulting in Inferred Classification of the Resource block model. Table four summarizes all the remaining intervals from the initial phase of this drilling. Torbrit remains open along the folded plunge of the deposit to the North and South along the prospective volcanogenic related mineralized horizon, and now within the connected area towards North Star.  The area is poorly tested to the east due to increasing topography on the east side of the Kitsault Valley.

About Dolly Varden Silver Corporation

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 that hosts a unique pure silver mineral resource as well as the nearby Big Bulk copper-gold porphyry 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 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 property to consolidate the Kitsault Valley Gold-Silver mineralization trend into one large, high-grade precious metals project with vast exploration upside. 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).
