First Cobalt reports positive borehole geophysics resultsStaff Writer | December 14, 2017
First Cobalt announced positive results from a borehole geophysics program in the Canadian Cobalt Camp.
Mining Vein-style mineralization
First Cobalt completed tests using a borehole electromagnetic (EM) system on ten drillholes in Cobalt South that are known to have intersected vein-style mineralization.
The objective of this program was to assess EM methods against known mineralized targets to validate this geophysical tool for future application in the Cobalt Camp.
EM surveys measure electrical conductivity contrast between conductive minerals containing metals such as cobalt and silver and the host rock.
The system detects conductivity in rocks intersected in the drillhole, an “in-hole response,” and away from the hole, an “off-hole response,” to a distance of approximately 100 metres.
Trent Mell, president & chief executive officer, commented: “Borehole electromagnetics may prove to be an effective tool for quickly detecting potential mineralization in the Camp. This signature connects veining logged in drill core with anomalous EM responses measured in-holes and potentially off-holes. We will continue to use EM type surveys in other areas to expedite future exploration planning.”
First Cobalt is the largest land owner in the Cobalt Camp in Ontario, Canada. The company controls over 10,000 hectares of prospective land and 50 historic mines as well as a mill and the only permitted cobalt refinery in North America capable of producing battery materials.
First Cobalt began drilling in the Cobalt Camp in 2017 and seeks to build shareholder value through new discovery and growth opportunities. ■
