Dolly Varden Silver (TSX.V:DV) is a Canadian-based mineral exploration company focused on the Dolly Varden silver properties located in Northwestern, British Columbia, Canada. The Dolly Varden Silver properties comprise 8,800 hectares (88 km2 ) and are located 25km by road from the deep tide water port town of Alice Arm. The property’s four historic deposits, mined in the 1920’s and 1950’s, are hosted in stratigraphy that is analogous to Barrick’s Eskay Creek and Pretium’s Brucejack deposits. The Company is focused both on the expansion of high-grade silver-base metal resources at the historic mines and on exploring the remainder of the property, which shows great potential for hosting further deposits.
A maiden NI 43-101 resource estimate completed by Dolly Varden in 2015 revealed 32 million ounces of silver in Indicated Resources (3.07 million tonnes grading 321.6 grams of silver per tonne (g/t Ag)) and an additional 11 million ounces of silver in Inferred Resources (0.9 million tonnes grading 373.3 g/t Ag) adjacent to the historic deposits. Drilling and underground work that went into the resource estimation confirmed that property mineralization occurs as two styles: bedding-parallel volcanogenic massive sulfide (VMS) mineralization, similar to that mined at Eskay Creek, as well as cross-cutting epithermal mineralization similar to that being developed at Pretium’s Valley of the Kings deposit. Both the Eskay Creek and Valley of the Kings deposits are located on the same structural trend to the north of Dolly Varden’s ground. Dolly Varden represents the silver end member of these styles of mineralisation and includes the base metals lead and zinc.
