Dolly Varden Silver is a mineral exploration company focused on advancing its 100% held Dolly Varden Project located in Northwestern, British Columbia, Canada which also includes the nearby Big Bulk Copper Gold porphyry property.
The Dolly Varden Project comprise 88 km2 and includes four deposits which combine to form its 100% silver resource including the past producing Dolly Varden and Torbrit mines, North Star and Wolf. The company is focused both on the expansion of high-grade silver resources at the historic mines and on exploring the remainder of the property, which shows great potential for hosting further deposits.
An updated NI 43-101 resource estimate completed by Dolly Varden Silver in 2019 calculated:
- 32.9 M ounces of silver in Indicated Resources at 300 g/t; and
- 11.477 M ounces of silver in Inferred Resources at 277 g/t.
Silver mineralization on the Dolly Varden Project occurs in two styles:
- Volcanogenic Stratabound similar to Skeena Resources’ Eskay Creek however with very low sulphide content, closely related to an exhalative deposit, and
- Cross-cutting epithermal veins
Metallurgic testwork combined with knowledge of past production on the Dolly Varden and Torbit mines suggests the potential to produce a clean concentrate with high silver recoveries. Credits of lead and zinc found in the mineralization has not been included in the resource estimate due to it not having been assayed with historical drilling.
