  Vancouver, British Columbia--(Newsfile Corp. - October 17, 2025) -  Dolly Varden Silver Corporation (TSXV: DV) (NYSE American: DVS) (FSE:  DVQ) (the "Company" or "Dolly Varden") announces  completion of the 2025 diamond drill program on the 100% owned Kitsault  Valley Project with a total of 56,131 meters in 84 drill holes. The  program has confirmed resource expansion through step-out and infill  drilling at the Wolf and Homestake Silver deposits as well as  intersecting new mineralization at numerous exploration targets  throughout the Kitsault Valley and Big Bulk copper-gold porphyry  project.
  "Early season high-grade, wide silver results from the  Wolf Vein backed up the expansion of the 2025 drill program from 35,000  meters to 55,000 meters at the Kitsault Valley with successful step-outs  and exciting new mineralized zones gives us a clear line of sight on  the next set of priorities. The team delivered safely and efficiently,  and the work strengthens our conviction in growing Kitsault Valley's  high-grade silver and gold potential. With fieldwork and core logging  complete, expect a steady cadence of updates as we integrate and release  assays," states Shawn Khunkhun, President & CEO.
  The 2025  drill program split approximately 60% on the Dolly Varden property and  40% on the Homestake Ridge property. The Company is using directional  drilling technology to precisely target areas for step-out and infill  holes at both the Wolf and Homestake Silver deposits. Utilizing the same  mother hole to drill multiple intersects of the targeted mineralized  zone in numerous daughter holes has increased efficiency and accuracy  over previous drilling.
