Dolly Varden Silver Intersects 978 g/t Ag over 5.00 meters, Including 3,670 g/t Ag over 0.79m at Moose Vein

Vancouver, British Columbia--(Newsfile Corp. - June 19, 2024) - Dolly Varden Silver Corporation (TSXV: DV) (OTCQX: DOLLF) (FSE: DVQ1) (the "Company" or "Dolly Varden") is pleased to announce the first drill results from the 2024 exploration program, intersecting high-grade silver mineralization at the Moose and Chance Veins within the Kitsault Valley Project. Three rigs are currently drilling with 25 holes completed or in-progress.

Highlights include*:

Moose Vein

• DV24-387: 977 g/t Ag over 5.00 meters, including 3,670 g/t Ag over 0.79 meters

Chance Vein

• DV24-388: 206 g/t over 23.03 meters, including 597 g/t Ag over 1.40 meters and 749 g/t Ag over 0.50 meters

*All intervals shown are core length. Estimated true widths vary depending on intersection angles and range from 70% to 90% of core lengths, further modelling of the new interpretation is needed before true widths can be calculated.

"These excellent results from the first hole at the Moose Vein from the 2024 program exhibits similar geological and mineralization features to the Wolf deposit located 1,400 meter south, suggests that this area has potential to emerge into the northernmost silver deposit along the 5 kilometer long trend that also hosts the Dolly Varden, Torbit and North Star deposits. Limited drilling has been completed at Moose and the robust nature of the mineralized structure suggests a strong mineralizing system. Additionally, the first results over a significant width from the Chance Vein are also very encouraging," said Shawn Khunkhun, CEO of Dolly Varden Silver.

Moose Vein*

The Moose Vein is located 1.4 kilometers north of the Wolf Vein on a similar crosscutting structure that projects under the mid valley sedimentary cap. Drillhole DV24-387 at Moose targeted the up plunge mineralization projection approximately 45 meters from previously reported mineralized interval in drill hole DV23-371 of 712 g/t Ag over 1.00 meter, within a wider vein interval grading 269 g/t Ag over 7.55 meters (from previous release; November 6, 2023). The Moose Vein remains wide open for expansion.

Chance Vein*

The Chance Vein is located 1.3 kilometers northeast of the Moose Vein, within the lower portion of the Hazelton Formation, just above the contact with the underlying Stuhini Formation (the contact known as "The Red Line" of the Golden Triangle). Drilling targeted the interpreted plunge direction of silver mineralization in an area that has not been previously tested. Drill hole DV24-388 at the Chance Vein tested approximately 30 meters down the interpreted plunge projection from drilling completed in the 1960s.

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.

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 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).
