Cow Mountain hosts the historic Cariboo gold quartz mine at the project that spans 1,950km2.
The company had released a maiden resource for Cow Mountain and Island Mountain in May, which took Cariboo's measured and indicated resource to 1.6 million ounces, grading 6.1g/t, and an inferred 2.16Moz.
Barkerville has started test mining at Cariboo's Bonanza Ledge as it moves to de-risk the project and generate cash-flow.
It reported in September better-than-expected grades of 7.05g/t from Bonanza Ledge and mill recoveries on track at 91.6%.
The company had C$27 million (US$20.5 million) in cash in September according to a recent presentation.
Its shares closed down C1c to 40.5c yesterday, towards the lower end of its 12-month range of 35-78c, capitalising it around $178 million.
