Dolly Varden Silver Corporation Announces Infill, Step-Out and Resource Expansion Drilling Results from the Wolf Vein
Dolly Varden Silver Corporation announced infill, step-out and resource expansion drilling results from the Wolf Vein. Drill hole DV24-421 is a significant 120 meter step-out down the plunge of the high grade silver zone and intersected 379 g/t Ag, 0.64% Pb and 0.66% Zn over 21.69 meters. The consistent thickness and silver grade of the mineralized zone remains wide open for expansion as it plunges to the southwest. DV24-421 is the southernmost hole completed to date; results have delivered consistent wide, potentially underground bulk-mineable intervals. These include recently reported step-out results completed during the 2024 season, including previously released: DV24-416, intersecting and 654 g/t Ag /0.47% Pb /0.57% Zn over 21.48 meters and DV24-408, intersecting 513 g/t Ag /2.95% Pb /1.82% Zn over 27.19 meters. This drilling has expanded the plunge of the silver mineralization to over 1,100 meters at the Wolf Vein. Further expansion drilling will be a priority during the Company's fully funded 2025 drilling program. Additionally, included in this release are results from follow-up exploration drilling from multiple prospects on the Dolly Varden Project Area. The Company's successful 2024 exploration drill program at the Kitsault Valley Project was expanded to 32,000 m from the initial planned 25,000 m. Wolf Vein Drilling Highlights include: DV24-421 - 120m step-out: 379g/t Ag, 0.64% Pb and 0.66% Zn over 21.69 meters, including 1,804 g/t Ag, 4.36% Pb and 3.10% Zn over 1.67 meters. DV24-406 - infill: 465 g/t Ag, 0.49% Pb and 0.22% Zn over 7.67 meters, including 1,416 g/t Ag, 1.56% Pb and 0.51% Zn with 0.24 g/t Au over 1.00 meters. DV24-413 - lower extension: 374g/t Ag, 0.54% Pb and 0.82% Zn over 9.70 meters, including 975 g/t Ag, 0.36% Pb and 2.28% Zn over 2.30 meters. Individual Pb/Zn veins in the footwall to the main Wolf Vein graded 130 g/t Ag, 2.48% Pb, 14.65% Zn over a length of 2.07 meters. DV24-415 - upper extension: 357 g/t Ag, 0.52% Pb and 0.41% Zn over 9.17 meters, including 2,034 g/t Ag, 3.47% Pb and 0.18% Zn over 1.15 meters. This release includes the final 13 holes of the total 22 drill holes (9,731 meters) completed at the Wolf Vein in the 2024. Six of the drill holes from this release are from the Wolf directional drilling program. Directional drilling technology was used to precisely target areas for vertical extension and infill of the high-grade silver mineralized plunge. Additionally, the final 17 of the total 19 drill holes (5,815 meters) from several other prospects on the Dolly Varden portion of the Kitsault Valley Project are reported in this release. Wolf Drilling The 2024 drilling program at Wolf was comprised of step-out exploration drilling, extension/definition of the vertical extent of the high-grade silver plunge and infill within areas of wide spaced drilling. Complete results are presented in table 1. Drill hole DV24-405 tested the vertical extent and targeted the upper area of high-grade silver plunge mineralization, intersecting the Wolf Main Zone with 12.58 meters averaging 227 g/t Ag /0.38% Pb /0.12% Zn and demonstrating that base metals decrease vertically up dip. This intercept includes high- grade vein breccias, including:953 g/t Ag over 1.00m and 536 Ag over 0.85m. Drill hole DV24-406 is an infill hole, intersecting mineralization approximately 45m below previously reported Wolf Extension discovery hole DV21-273 and 70m above previously released DV24-402. This hole intersected the Wolf Vein grading 465 g/t Ag /0.49% Pb /0.22% Zn over a length of 7.67 meters, including a 1.00 meter interval grading 1,416 g/t Ag /1.56% Pb /0.51% Zn and 0.24 g/t Au. Drill hole DV24-407 tested a potentially parallel, deep zone approximately 33 meters east of drill hole DV22-311, intersecting the structure and associated alteration with a vein grading 202 g/t Ag over 1.53m along with promoted zinc grades, which was also encountered in adjacent drill holes. Drill hole DV24-411 tested the vertical extent and targeted the upper area of the high-grade silver plunge and intersected the Wolf structure and associated alteration further up-dip. Vein style mineralization was intersected over 1.08 meters, grading 332 g/t Ag with high base metal grades of 1.24% Pb and 3.29% Zn. Drill hole DV24-413 was drilled to test the down-dip extent of the high-grade plunge, approximately 50 meters from DV24-410 and below DV24-405. The hole encountered 25.00m of 0.17% Zn in the hanging wall alteration. Drill hole DV24-413 intersected 9.70 meters averaging 374 g/t Ag along with strong base metals; this wide, central portion of the high-grade silver plunge was encountered approximately 30 meters up plunge from DV24-410. Drill holes DV24-417, 418 tested the down-dip extent of the silver mineralization, intersecting the Wolf structure below the wider plunge but still showing intervals with strong zinc values over narrower intervals. Drill holes DV24-419, 420 tested for extensions to previously released drill hole DV22-329, which intersected 24,997 g/t Ag, 1.24% Pb and 0.35% Zn over 0.35 meters (February 06, 2023). DV24-420 intersected a post-mineralization dyke and DV24-419 intersected a strong alteration zone with 201 g/t Ag over 0.99 meters. The intercept in DV22-329 remains open for expansion. Drill hole DV24-421 is a 120m step-out to the south along the plunge of the high-grade silver zone (75 meters along strike) from previously released drill hole DV24-409. This hole was drilled towards the west from the Wolf access road that connects the historic Torbrit Mine to the Wolf exploration adits, intersecting 379g/t Ag, 0.64% Pb and 0.66% Zn over 21.69 meters. Drill holes DV24-425, 426 filled a gap above the projected silver mineralization, testing for a connection between the Wolf Vein and of the Wolf Extension below the sediment cap. The potassic alteration with zinc halo within the host structure was observed in drill core, with narrow silver-bearing veins along with anomalous base metal signature. 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 high 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 to the south west of the outcropping Wolf Vein has a plunge extent of over 1,100 meters at approximately -45° to the southwest.
