Vancouver, British Columbia--(Newsfile Corp. - August 19, 2024) - Dolly Varden Silver Corporation (TSXV: DV) (OTCQX: DOLLF) (FSE: DVQ1) (the "Company" or "Dolly Varden") is pleased to announce additional results from the Wolf Vein step-out directional drilling. Drill hole DV24-412 averaged 606 g/t Ag over 16.20 meters on a 45m step-out from 2023 drilling and 31m below DV24-404 (previously released August 12, 2024). Approximately 8,000 meters of an ongoing 25,000m drill program at the Company's 100% owned Kitsault Valley Silver and Gold Project is being drilled at the Wolf Vein to expand and infill the plunge of high-grade silver mineralization.

Wolf Vein Step-out Drilling

Highlights include:

• DV24-412: 606 g/t Ag, 0.61% Pb and 1.43% Zn over 16.20 meters, including 868 g/t Ag, 0.18% Pb and 0.88% Zn over 2.27 meters.

• DV24-414: 771g/t Ag, 2.93% Pb and 2.29% Zn over 3.77 meters, including 1,065 g/t Ag, 4.64% Pb and 3.48% Zn over 2.26 meters within a 15.02m wide vein breccia zone grading 254 g/t Ag, 0.86% Pb and 1.34% Zn.

* intervals shown are core length. Estimated true widths vary depending on intersection angles and range from 60% to 70% of core lengths, further modelling of the new intersections is needed before true widths can be estimated.

"The strength of mineralization including strong native silver and pyrargyrite plus strong, accessory base metals appear to be increasing to the southwest as we vector towards a key structural intersection point. These holes, oriented by directional drilling, show excellent continuity of the high-grades at the Wolf Vein," said Shawn Khunkhun, CEO of Dolly Varden Silver

A total of four southwest step-out holes have been completed from one drill pad using directional drilling technology to precisely target areas for step-out and infill work. Drillholes DV24-409, DV24-412 and DV-414 reported in this release are "daughter" holes directed off the initial "mother" hole DV24-404 that grades 1,091 g/t Ag over 9.38 meters (previously released August 12, 2024).

The wide, high-grade silver intersection in drill hole DV24-412 is located 31 meters below previously reported drill hole DV24-404 and demonstrates that the vertical extent of the plunging high-grade zone is consistent at depth.

DV24-409 is the step-out furthest southwest drilled from this position and intersected the Wolf mineralized zone 75 meters from 2023 drilling. The silver-bearing vein breccia intersection grades 421 g/t Ag over 2.72 meters within a zone that is 10.32 meters core length consisting of various vein and vein breccias. As seen in other drill holes at the upper and lower vertical extents of the wider, higher grade silver plunge, there is a separate vein breccia zone with higher base metal values within that interval that averaged 94 g/t Ag, 1.30% Pb and 2.39% Zn (Table 1).

Drill hole DV24-414 targeted the lower portion of the high-grade plunge, approximately 65 meters vertically below and northeast of DV24-404. This hole intersected 15.02 meters of vein breccias that had a mix of low grade and high-grade silver, lead and zinc mineralization averaging 254 g/t Ag, 0.86% Pb and 1.34% Zn overall, with higher grade intervals attributed to more sulphide rich breccias grading 771g/t Ag, 2.93% Pb and 2.29% Zn over 3.77 meters (table 1).

Wolf Vein

The Wolf Vein is hosted in Jurassic-age Hazelton Formation volcanic rocks and is interpreted as a structurally controlled, multi phased, epithermal vein and vein breccias that occur along a southwest plunging zone of wider, higher grade silver mineralization. Native silver, pyargerite, argentite and argentiferous galena are hosted in multiple phases of silica and iron carbonate veins and breccias. The extention of the mineralization discovered underneath the sedimentary rock cap and the outcropping Wolf deposit has a plunge extent of over 950 meters at -45 to the southwest.

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 also determined by fire assay on a 30g split with either atomic absorption, or gravimetric finish, depending on grade range. Metallic screen on a 1.0kg sample may be completed on high-grade gold samples.

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 at the Dolly Varden 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, on-trend, high-grade deposits, such as Eskay Creek and Brucejack. Five kilometers to the East of the Kitsault Valley Project is 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).
