Dolly Varden Silver Intersects 4.66 g/t Gold over 48.49 meters, including 52.15 g/t Gold and 306 g/t Silver over 1.01 meters at Homestake Silver Deposit
Press Release
VANCOUVER, BC, February 4, 2026, Dolly Varden Silver Corporation (TSX-V: DV | NYSE MKT: DVS | FSE: DVQ) (the “Company” or “Dolly Varden“) is pleased to report results from drilling that successfully infilled and expanded the northerly plunging, high-grade gold and silver mineralized trend at the Homestake Silver deposit. A total of 29 drill holes were completed at Homestake Silver and two at Homestake Main in the 2025 program, five of which have been released previously. Highlights from the silver-rich southern portion of the deposit from drill hole HR25-466 intersected a wide mineralized zone averaging 4.66 g/t Au and 33 g/t Ag over 48.49 meters and included narrower high-grade veins and vein breccias returning grades of 52.15 g/t Au and 306 g/t Ag over 1.01 meters and 46.55 g/t Au and 298 g/t Ag over 1.87 meters.
Highlights from southern Homestake Silver deposit:
HR25-466: Infill in silver-rich southern zone
4.66 g/t Au and 33 g/t Ag over 48.49 meters, including
52.15 g/t Au and 306 g/t Ag over 1.01 meters and
46.55 g/t Au and 298 g/t Ag over1.87 meters
HR25-470: On section with HR25-466, 87 m down dip step-out
5.25 g/t Au and 31 g/t Ag over 38.74 meters, including
123.50 g/t Au and 760 g/t Ag over 0.86 meters and
25.00 g/t Au and 73 g/t Ag over0.75 meters
HR25-473: Infill in silver-rich southern zone
1.08 g/t Au and 58 g/t Ag over 95.99 meters, including
4.99 g/t Au and 989 g/t Ag over 0.95 meters and
23.30 g/t Au and 598 g/t Ag over0.52 meters and
18.25 g/t Au and 233 g/t Ag over 0.50 meters
* Intervals shown are core length. Estimated true widths vary depending on intersection angles and range from 55% to 75% of core lengths, further modelling of the new intersections is needed before true widths can be estimated.
“The 2025 drill program at the Homestake Silver Deposit successfully expanded and infilled at the Mineral Resource area, demonstrating strong gold and silver grades over potentially underground bulk-mineable widths,” said Shawn Khunkhun, President and CEO of Dolly Varden Silver. “The deposit remains open for expansion, and we look forward to accelerating drilling and engineering studies to advance the Homestake Main and Homestake Silver Deposits during 2026.”
The 2025 drill program at Homestake Ridge targeted three areas focused mainly at Homestake Silver. First, infill drilling within the southern silver-rich zone, with drill results highlighted above. Second, infill and down-dip drilling within the central portion of the zone. Third, expansion drilling at the northern end and down dip tests below the know extent of mineralization.
The infill and down dip extension drill holes in the central zone of Homestake Silver are mainly along the lower boundary of the projection of the northerly plunging, high-grade trend. Gold assay results from the mineralized intercepts outline a downdip expansion of the zone for approximately 100 metres over a 350-meter strike length in this central area. The 2025 intercepts within the central area are shown in area 2 on the long section in Figure 1.
Step-out drilling at the northern end of the mineralized trend and below the deposit successfully expanded the extent of mineralization with drill holes HR25-458 and HR25-460 stepping out to the northwest from previously released drill hole HR25-456, that graded 3.34 g/t Au over 120 meters, including 216 g/t Au over 0.52 meters and 166 g/t Au over 1.3 meters (see October 1, 2025 News Release).
The 2025 drilling also expanded the down-dip potential below the deposit, intersecting mineralization consisting of high-grade vein and vein breccias within an approximately 10-meter wide stockwork and alteration zone, highlighted by drill holes HR25-454 and HR25-483 below.
Highlights from Expansion Drilling at Homestake Silver:
HR25-458: North step-out expansion
2.50 g/t Au and4 g/t Agover 80.00 meters, including
39.39 g/t Au and39 g/t Ag over 3.25 meters and
11.75 g/t Au and 8 g/t Agover 0.86 meters
HR25-460: North step-out expansion
1.81 g/t Au and 7 g/t Agover 39.21 meters, including

6.14 g/t Au and9 g/t Agover 10.66 meters, including
61.20 g/t Au and 60 g/t Ag over 0.87 meters
* Intervals shown are core length. Estimated true widths vary depending on intersection angles and range from 50% to 65% of core lengths, further modelling of the new intersections is needed before true widths can be estimated.

Homestake Silver
At total of 56,131 meters were drilled in 86 drill holes during the 2025 season by Dolly Varden Silver at the Kitsault Valley Project with approximately 40% of the meters drilled at Homestake Ridge focused on step outs and local infill at Homestake Silver.
The Company is using directional drilling technology to precisely target areas for step-out and infill holes at Homestake Silver. Several single holes utilized directional drilling to precisely intercept the target within the mineralized zone, while other areas used multiple holes based off a central mother hole.
The Homestake Ridge Deposits are interpreted as structurally controlled, multi-phase epithermal vein stockwork and vein breccia system hosted in Jurassic Hazelton volcanic rocks. Mineralization consists of pyrite, +/- galena and sphalerite, with visible gold in a silica breccia matrix. The northwest trending structural corridor hosts multiple subparallel structures that control high-grade gold and silver shoots within a broader mineralized enveloper.
Although historically considered a silver-rich gold deposit, recent drilling at Homestake Silver has defined a shallow north plunging zone that is defined by wide mineralized intervasl with increased frequency of high-grade gold veins and vein breccias which shows a shift towards a gold-rich system towards the north. The deposit remains open along plunge and at depth.

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’s 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.

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. Including the Kitsault Valley Project, the Company has consolidated approximately 100,000Ha of prospective tenure in the Golden Triangle with five past-producing high-grade silver mines including Dolly Varden, Torbrit, Porter Idaho, Mountain Boy and Esperanza historic mines. The 163 sq. km. Kitsault Valley 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. 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).
