Dolly Varden Silver Corporation announced results from drilling at the Wolf Vein, including step-out hole DV22-300 which returned a significant, high-grade silver intercept. Based on the grade and strength of the mineralizing system, the Company has prioritized continued step-out drilling at Wolf during for the remainder of the 2022 season. DV22-300 encountered a wide interval of multi-phase veins and breccia, intersecting 19.85m (13.90m true width) averaging 584 g/t Ag, 0.92% Pb, 0.56% Zn and 0.19 g/t Au, with bonanza grade silver mineralization grading 4,326 g/t Ag, 4.21% Pb, 1.36% Zn and 1.00 g/t Au over 1.60m (1.12m true width) within a sulphide and silver sulphosalt matrix vein breccia in the main veined interval.

The mineralized interval in DV22-300 is a southwesterly step-out along strike and down dip from DV21- 273, which returned 17.50m averaging 214 g/t Ag and 0.47% Pb including 1.22 m averaging 1,532 g/t Ag, 0.44 g/t Au, 2.11 % Pb and 1.07% Zn and projects as a mineralized shoot over 55m down plunge from DV21-273. High-grade silver in DV22-300 occurs within a very strong, multiphase vein and breccia system that also includes significant gold and base metal mineralization. The strength of the mineralizing system, as well as silver and potentially gold appears to be increasing at depth and to the southwest; assays are pending for DV22-316, which encountered strong veining, alteration, brecciation and one occurrence of visible gold over 200m away from DV22-300.

All of these drill holes tested below the Upper Hazelton sediment cap with associated strong potassic alteration; this trend continues south for 1,400 m to the Kitsol Vein. The Wolf Vein is a steep dipping, high-grade silver vein deposit that is part of the current Mineral Resource Estimate at Dolly Varden's Kitsault Valley trend. In 2021, geological modelling of the deposit showed expansion potential along strike to the southwest below the sediment cap that masks surface expression of the vein mineralization and associated alteration.

With the discovery that the system continued to the southwest over 8,000m of follow up drilling has been completed thus far during the 2022 exploration program. This drilling has defined high grade silver mineralization to a depth of 500m below surface and extended the zone over 350m down plunge from historic drilling and over 500m from the historic underground workings. Results have been received for the first six exploration drill holes testing the Wolf Vein extension.

All holes were drilled from the same pad with varying azimuths and dips. These drill holes tested below the Upper Hazelton sediment cap and have encountered a robust, multi-phase vein and breccia mineralizing system that remains wide open along strike to the south and down dip. The associated strong potassic alteration, a key indicator for silver mineralization at the Kitsault Valley Project, continues below the sediment cap and south for 1,400m to the Kitsol Vein.

All holes drilled during 2022, except DV22-280, intersected the extension of the Wolf Vein, suggesting a plunge at approximately 45 degrees to the southwest. DV22-280 came out of the sediment cap into the footwall of the vein. Drill hole DV22-281- intersected impressive base metal values in addition to silver: 3.75m (2.43m true width) averaging 170 g/t Ag, 6.25% Pb, 14.12% Zn.

In drill holes that hit the Wolf vein outside of the interpreted plunge of the high-grade silver zone, significant lead and zinc intervals are present. Mineralization at the Wolf Vein consists of multiple epithermal silica vein and brecciation events along a NE trending, steeply NW dipping zone. Silver mineralization includes: silver sulphosalts, tennantite, argentite and argentiferous galena hosted in vein and vein breccia mineralization.
