Canada Cobalt Works Inc. said Dec. 14 that two drillholes at its Castle silver property in Ontario intersected what appears to be a syenite-hosted gold system with nearby cobalt in a previously undrilled area near the past-producing Gowganda silver camp.

Underground drilling on the first level of the Castle mine, 1.5 kilometers from the new discovery, continued to identify cobalt-silver vein structures occasionally also containing gold and nickel.

Additionally, the company started a new drillhole designed to expand the system by intersecting gold mineralization. It is also preparing to kick off a second, expanded phase of underground drilling through an amended exploration permit in early 2019.

Canada Cobalt said it expects to provide first-phase underground drill results soon.

In June, the company started building a pilot plant at Castle to produce bulk gravity concentrates for processing into cobalt sulfate.
