Vancouver, British Columbia--(Newsfile Corp. - September 11, 2023) - Dolly Varden Silver Corporation (TSXV: DV) (OTCQX: DOLLF) (the "Company" or "Dolly Varden") is pleased to announce drill results from the Wolf Vein, which includes drill hole DV23-368, a 75 meter step-out down plunge, which intersected 1,898 g/t Ag over 1.00 meters within 381 g/t Ag over 29.34 meters core length. Five drills have completed over 43,000 meters of the expanded 55,000 meter drill program at the Dolly Varden and Homestake Ridge areas. This release includes 19 drill holes from early season drilling at the Wolf.
Highlights from the Wolf Vein drilling include*:
- DV23-368, Southwest Extension step-out: 381 g/t Ag, 0.46% Pb, 0.39% Zn over 29.34 meters (22.59 meters estimated true width), including 1,898 g/t Ag over 1.00 meter (0.77 meter estimated true width) from a 75m step-out
- DV23-352, Southwest Extension: 246 g/t Ag over 18.07 meters (12.29 meters estimated true width) including 712 g/t Ag over 2.95 meters (2.01 meters estimated true width)
- DV23-339: 287 g/t Ag. 0.35 g/t Au and 22.83% Pb over 2.65 meters (1.67 estimated true width)
* Intervals are core length; true widths vary from 50 to 83% of core length interval (see table 1), assays are uncut
"As the drilling progresses at Wolf we are seeing the continuity to depth of the high-grade silver mineralization," said Shawn Khunkhun, President and CEO of Dolly Varden Silver. "Drill hole DV-368 has extended the length of potentially underground bulk-mineable mineralization plunge to over 950 meters and it remains wide open for expansion, with ongoing drilling continuing to step-out to the south."

Holes DV23-368 is a 75m step-out along plunge from drill hole DV22-320 that graded 321g/t Ag over 12.85 meters (February 6, 2023 news release). Drilling continues to expand the length of the Wolf Vein mineralization with consistent, high-grade silver mineralization within the wide vein breccia. The mineralization within the Wolf vein is comprised of multiple phases of brecciation within a northeast-southwest oriented epithermal vein system.
Initial holes at Wolf during the 2023 drill program tested between the widely-spaced holes completed the previous season and successfully intersected the vein structure both within and peripheral to the southwest plunge of the high grade silver mineralization. Drilling has been ongoing at Wolf since the start of the 2023 program and continues with infill and testing for extensions to the high-grade silver mineralization.
Drill hole DV23-359 is a 50 meter step-out from drill hole DV22-311 (See February 06, 2023 news release) that graded 412 g/t Ag over 12.80 meters, including 1,646 g/t Ag over 2.1 meters within a vein spay. Deviation in hole DV23-359 shallowed the planned dip, encountering the vein over 100m up dip from DV22-311. It intersected the Wolf splay vein as a 30 cm wide sulphide-rich vein (2.25%Pb over 0.50 meters core length). Subsequent drilling, with assays currently pending, intersected the subparallel vein splay vein on either side of DV22-311.
Drill holes DV23-347, 351, 354 and 356 are step outs targeting the eastern extension of the veins, collared east of the high-grade intercept of DV22-329 (See February 6, 2023 News Release). The drill holes did not intercept mineralization, suggesting that the vein breccia may have a more northeasterly strike and parallel the main host structure. It remains open to the northeast and will be drilled shortly.

2023 Drill Program Update
The 15km long extent of the prospective Hazelton rocks on the property is host to numerous surface occurrences of alteration and silver mineralization that have been prioritized for drill testing. With the additional meters available under the current budget, drill holes have been planned at discovery-focused exploration targets. Currently, the drills are testing exploration targets peripheral to the Homestake Ridge deposits and will be moved down the valley to follow up on exploration targets beneath the sediment cap as well as at the southern end of the western Gold Belt that extends 10 kilometers from Homestake Ridge to Red Point.

Quality Assurance and Quality Control
The Company adheres to CIM Best Practices Guidelines for exploration related activities conducted on its property. Quality Assurance and Quality Control (QA/QC) procedures are overseen by the Qualified Person.
Dolly Varden QA/QC protocols are maintained through the insertion of certified reference material (standards), blanks and field duplicates within the sample stream. Drill core is cut in-half with a diamond saw, with one-half placed in sealed bags and shipped to the laboratory and the other half retained on site. Third party laboratory checks on 5% of the samples are carried out as well. Chain of custody is maintained from the drill to the submittal into the laboratory preparation facility.
Analytical testing was performed by ALS Canada Ltd. in North Vancouver, British Columbia. The entire sample is crushed to 70% minus 2mm (10 mesh), of which a 500 gram split is pulverized to minus 200 mesh. Multi-element analyses were 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. Au is determined by Fire Assay on a 30g split.
Qualified Person
Rob van Egmond, P.Geo., Vice-President Exploration for Dolly Varden Silver, the "Qualified Person" as defined by NI43-101 has reviewed, validated and approved the scientific and technical information contained in this news release and supervises the ongoing exploration program for Dolly Varden on the Kitsault Valley Project.
About Dolly Varden Silver Corporation
Dolly Varden Silver Corporation is a mineral exploration company focused on advancing its 100% held Kitsault Valley Project (which combines the Dolly Varden Project and the Homestake Ridge Project) located in the Golden Triangle of British Columbia, Canada, 25kms by road to tide water. The 163 sq. km. project hosts the high-grade silver and gold resources of Dolly Varden and Homestake Ridge along with the past producing Dolly Varden and Torbrit silver mines. It is considered to be prospective for hosting further precious metal deposits, being on the same structural and stratigraphic belts that host numerous other, high-grade deposits, such as Eskay Creek and Brucejack. The Kitsault Valley Project also contains the Big Bulk property which is prospective for porphyry and skarn style copper and gold mineralization, similar to other such deposits in the region (Red Mountain, KSM, Red Chris).
