Dolly Varden Silver Corporation owns an exploration property called the Big Bulk Project, located in northwestern British Columbia, Canada. Big Bulk consists of 2,640 hectares in 7 mineral claims covering a copper-gold porphyry and skarn prospect on the southern shores of Kinskuch Lake, approximately 5 km east of the Dolly Varden Project and 23 km northeast of the village of Kitsault.

Big Bulk is in alcalic porphyritic rocks of the Hazelton Group, with altered quartz monzonite intrusives. Analogues for Big Bulk are the large Sulphurets (KSM) deposits of Seabridge and Red Mountain deposit of IDM Mining.

Intermittent exploration programs have taken place over several decades. Short historic drilling programs have been conducted by AngloGold Ashanti, Agnico Eagle, Teck Resources and Homestake Resources Corp.. AngloGold Ashanti drilled hole AGA01 in 2009 and intercepted 0.31% Cu over 54 metres from 67 to 121 m, plus 4.0 g/t Au over 10 metres from 427 to 437 m, coincident with an IP chargeability geophysical anomaly.

As a separate mineral claim, but part of the Big Bulk Project, is the Midnight Blue claim. This location has a large copper-gold anomaly in talus fines and suggests the Big Bulk mineralization extends approximately 4 km from Kinskuch Lake southwards under ice cover to Midnight Blue.

Two neighbouring companies, Hecla Mining Limited and OK2 Minerals, hold mineral claims contiguous with Big Bulk on their respective Kinskuch projects. In 2017, OK2 Minerals conducted mapping and surface rock sampling on their mineral claims. Hecla conducted a short diamond drilling program on targets to the south in the Illiance River area. Also in 2017, a joint study by the University of British Columbia and the British Columbia Geological Survey (BCGS) consisting of structural geology mapping was conducted over the Big Bulk area, with logistical support from Dolly Varden Silver.
