Dolly Varden Silver Corporation (TSX-V: DV) (OTC: DOLLF) is pleased to announce drill results from its 2024 program at the Homestake Silver deposit and exploration drilling at the Homestake Ridge Property in BC’s Golden Triangle. The twenty drillholes reported in this release have successfully expanded and infilled multiple high-grade gold and silver-rich zones within the Homestake Silver Deposit. Three drillholes reported in this release tested exploration targets across various prospects on the property. Dolly Varden’s 2024 drill program consisted of 69 drill holes for a total of 31,726m, with 41 holes totalling 15,546 meters drilled at the Dolly Varden area and 28 holes totalling 16,181 meters drilled at Homestake Ridge area. Planning for the fully funded 2025 drill program is underway to build on the expanded silver and gold zones drilled in 2024.

Highlights from the Homestake Silver Deposit Area (*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 interpretation is needed before true widths can be calculated

“Homestake Silver was originally considered a primary silver-rich deposit, however our drilling has continued to identify multiple gold-rich zones and remains wide open for expansion.  Fully funded drilling in 2025 will target continued growth and further infill-drilling as a high-priority amongst the many targets in the Kitsault Valley trend,” said Shawn Khunkhun, CEO of Dolly Varden Silver.

Homestake Silver

2024 drilling at Homestake Silver targeted infill of Inferred Resources and Resource expansion drilling along strike to the north and south, as well as the down-dip. Complete drill results are presented in Table 1.

Highlight drill hole HR24-431 intersected 21.55 g/t Au and 27 g/t Ag over 8.72 meters, including 47.92 g/t Au and 58 g/t Ag over 3.74 meters. This is one of five drill holes targeting the northern extension of Homestake Silver deposit by testing the projected extension of the shallow angle plunge of wider, higher grade gold mineralization (Figure 3). HR24-431 targeted 180 meters down plunge from previously released drill hole HR23-410, that intersected 10.17 g/t Au over 6.61 meters, including 50.70 g/t Au over 0.62 meters (February 12, 2024, news release).

The other four drill holes testing the extent of the northern gold-rich zone all intersected a broad alteration zone with internal areas of strong veining and vein breccias. Drill hole HR24-433 intersected the new gold-rich zone to the east of the main Homestake Silver trend, grading 3.48 g/t Au and 13 g/t Ag over 29.50 meters and included higher grade vein intervals of 35.05 g/t Au and 114 g/t Ag over 2.32 meters (Figure 5). HR24-433 stepped out from previously released hole HR23-399, that intersected the new east gold lens grading 2.68 g/t Au and 20 g/t Ag over 57.70 meters and included higher grade vein intervals of 43.10 g/t Au and 66 g/t Ag over 1.01 meters and 40.33 g/t Au and 418 g/t Ag over 1.75 meters. (February 12, 2024, new release).

Drill hole HR24-425 was drilled at an orientation to test the continuity of the new style of quartz-carbonate veining with abundant visible gold intersected in previously released drill hole HR23-389 (February 12, 2024, news release). HR24-425 intersected individual veins grading 8.86 g/t Au over 0.84 meters and 5.78 g/t Au over 2.00 meters.

Drill holes HR24-426 and HR24-449 tested the possible connection of Homestake Main and Homestake Silver deposits with a 250 meter step-out along the projected trend from Homestake Silver. Both drill holes intersected alteration associated with the continuation lower grade anomalous Au that indicate the structural corridor is continuous between the deposits.

Eight drill holes were drilled as infill holes to target larger gaps in drillhole spacing to aid in geological interpretation and increase resource confidence. These holes intersected wide mineralized envelopes with internal high-grade zones of strong veining and vein breccias. Wider zones include: 5.54 g/t Au and 97 g/t Ag over 10.20 meters in HR24-437 and 4.48 g/t Au and 16 g/t Ag over 14.33 meters in HR24-438. Drill holes HR24-437 and HR24-438 targeted a section located 32 meters south of previously released drill hole HR23-407 which intersected 8.94 g/t Au and 191 g/t Ag over 10.72 meters length (January 16, 2024, News Release). Holes HR24-446 and HR24-448 were drilled off the same pad but at different azimuths (Figure 3). Hole HR24-446 intersected 1.71 g/t Au and 287 g/t Ag over 2.91 meters including 7.06 g/t Au, 1,580 g/t Ag, 2.25% Pb and 2.54% Zn over 0.5 meters.

Drill holes HR24-436 and HR24-439 targeted the down-dip extension of the known mineralization and are separated by 110 meters along strike (Figure 4). Drill hole HR24-439 was a 170-meter down dip test from the main mineralized plunge and indicates that mineralization continues at depth and remains open for expansion. The alteration and veining intersected in holes HR24-436 graded 1.09 g/t Au over 31.75 meters, including 11.10 g/t Au over 0.55m and HR24-439 graded 1.56 g/t Au over 28.90 meters including 12.15 g/t Au over 1.00 meters.

Homestake Ridge

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 breccia matrix within a silica breccia vein system (see Figure 2). The northwest orientation of the main Homestake structural trend appears to have numerous subparallel internal structures that are interpreted to form the controls for higher grade gold and silver shoots within a broader mineralized envelope at the Homestake Silver deposit. The main structural corridor dips steeply to the northeast at Homestake Main and rolls to vertical or steeply southwest at Homestake Silver.

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 assays may be completed on very high grade 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. 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. 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).
