VANCOUVER, BC, Feb. 16, 2021 /CNW/ - Dolly Varden Silver
Corporation ("Dolly Varden" or the "Company") (TSXV:
DV) (OTC: DOLLF), is pleased to announce the results of the
remaining assays from the 2020 drill program from it's 100% owned
Property located near tidewater in northwest British Columbia. The work completed during
the 2020 Exploration Program included infill and step-out drilling
at Torbrit Deposit as well as regional mapping, surface sampling
and exploration drilling.
The high-grade silver deposit at Torbrit hosts the largest
43-101 Mineral Resource of the three silver deposits at the Dolly
Varden Silver Project. Torbrit continues to show its potential as
the most significant silver deposit on the Property and is
considered among the most advanced pure silver assets in
Canada, with further room for
expansion at depth and along strike. The historic workings from the
Torbrit mines past production support underground access to silver
mineralization and surface infrastructure provides direct road
access to deep tidewater docks at Alice Arm, BC. Highlights
from the recent drilling program include:
- DV20-222: 310 g/t silver over 6.00 meters, including
1,083 g/t silver over 2.70 meters
- DV20-244: 304 g/t silver over 45.82 meters, including
642 g/t silver over 4.00 meters
- DV20-246: 306 g/t silver over 5.10 meters, including
1,290 g/t silver over 0.60 meter
The true width of intercepts is estimated to be 80-95% of the
Core Length (m) reported using the current understanding of the
three-dimensional nature of the mineralization and grade models at
Torbrit. Interval lengths are constrained by grade values within
the mineralization envelope. Recoveries on the individual metals
have not been applied to composite calculations which are reported
at 100%.
"We are seeing consistent intervals of high-grade silver
mineralization at the Torbrit Silver deposit that has the potential
to support economically attractive underground bulk-mining
technics, while at the same time each successive drill programs
continues to demonstrate that the deposit is open for
expansion. As part of our 2021 work plan, we are considering
further underground work at Torbrit to develop better access for
test mining and bulk sampling, as well as resource expansion and
exploration drilling at depth and along strike to the east of
Torbrit. While silver exploration is our primary focus on the
Property, we are highly encouraged with the geological and
pathfinder element geochemical results for gold and copper
mineralization from the four-kilometer long early-Jurassic volcanic
and intrusive trend located northwest of our growing silver
deposits. Therefore, we can not rule out a gold discovery
consistent with the plus million-ounce resource at the adjacent
Homestake property in addition to the potential for another Torbrit
like silver discovery," said Shawn
Khunkhun, President and CEO of Dolly Varden
Silver.
A total of 11,397 meters in 40 drill holes were completed during
the 2020 exploration program at Dolly Varden. 19 holes were
completed in the Torbrit area and 21 reconnaissance and exploration
drill holes were drilled, testing multiple areas on the
Property.

This release represents the results from continued exploration
within the Torbrit Silver Mine Area (initial results released
October 07, 2020), with a focus of
step-out drilling and infilling areas of sparse data.
Additionally, exploration drilling to test structures and
stratigraphy prospective for silver mineralization along the
4.5km long volcanogenic-related stratigraphy that hosts the Torbrit
Silver deposit. Initial exploration and reconnaissance drilling was
also completed on the western portion of the property where
strongly quartz-sericite-pyrite altered early-Jurassic volcanic and
intrusive rocks with associated gold and pathfinder element
anomalies in soil geochemistry occur in a similar setting to
well-known deposits and mines located further north in the Golden
Triangle.
Planning for the 2021 Dolly Varden exploration program is
underway, utilizing the geological data from the past year's
program.
Torbrit Resource Area
The 45.82 thick intercept in drill hole DV20-246 expanded
mineralization vertically from the current Mineral Resource model
at the Torbrit. Based on historic underground drilling,
mineralization is interpreted to be a contiguous, broad package of
exhalative with epithermal overprint veins and breccias at the
deposit These areas of mineralization are situated above historic
underground infrastructure.
DV20-246 was an infill hole drilled from the same pad as
DV20-244 to test the eastern extent of the internal high-grade zone
and confirmed modelled mineralization proximal to historic
workings.
Drill hole DV20-222 was a 35m step
out to the west of the nearest drill hole, with subsequent infill
hole DV20-244 drilled 15m to the east
of it. The intercept in DV20-222 aligns with the extrapolated block
model but demonstrates an increase in the composite silver grade
over the interval.
Three holes (DV20-235, 238 and 240) drilled at the Wolf deposit,
included in the Current Mineral Resource; drilling tested potential
extensions 150 meters north and further down-dip of the structures
that host epithermal-style silver mineralization. Silver-bearing
structures were suggesting that the system remains open for
expansion.

Exploration Drilling 2020
All drilling during 2020 was completed using oriented drill core
techniques, for use in an ongoing structural re-interpretation of
the entire Project. Drill holes testing structures within the 4.5
kilometer-long horizon that hosts potassium alteration, trending
north from the Torbrit deposit, will provide valuable geological
information in the exploration for additional volcanogenic-related
depositional basins as well as associated structurally controlled
epithermal silver-bearing veins and breccias.
Drill hole DV20-245 tested the Chance structure approximately
450 meters west of the 2019 drilling and intercepted the target
structure. Subsequent drilling will vector towards
higher-grade and wider shoots in this area.
Reconnaissance Drilling on Western Gold
Belt
Initial reconnaissance drilling was completed in the
western "Gold Belt"; this area is typified by a separate
north-northwest trend, separate to the area that hosts the main
silver deposits and past-producing mines on the Property.
This area is typified by a strong QSP (quart-sericite-pyrite)
alteration trend that projects north towards Fury Gold's Homestake
Ridge Deposit. Dolly Varden is targeting a similar geological
setting in early-Jurassic volcanic and intrusive rocks to other
significant gold-silver and copper-gold deposits in the Golden
Triangle. Drilling encountered hydrothermal breccias and
quartz stockwork veining and strong pyrite with pathfinder elements
such as bismuth, copper, lead and zinc, as well as anomalous gold
(up to 0.1 g/t Au). The polymetallic quartz-carbonate
structures appear similar to those that host high-grade zones and
shoots at the Big Missouri, Premier and Brucejack deposits located
north of Dolly Varden.
At the 1.5 km long Starlight-Racehorse trend within the
western gold belt, the alteration and quartz stock work in
exploration drill holes DV20-226 and DV20-228 (850 m apart) returned 0.19 g/t Au with 0.62%
Cu over 8.00m core length and
0.06 g/t Au with 1.36% Cu over a core length of 3.65m respectively. The company is encouraged
by these results and is planning further work in the western Gold
Belt alteration zone.
Torbrit Deposit
The main Torbrit deposit hosts stratiform exhalative-style
silver mineralization within volcanic rocks that is overprinted by
epithermal vein mineralization, with associated lead and zinc.

map can be found at https://www.dollyvardensilver.com/
