Canada Cobalt Works reported in late January that ongoing drilling from surface has greatly expanded the potential scale of its Castle East Robinson Zone high-grade silver discovery immediately adjacent to three robust past producing mines in northern Ontario’s Gowganda camp, 75 km southwest of Kirkland Lake.
Significantly, native silver has been observed in drill core at shallower levels near the contact of the Nipissing diabase with the Archean volcanics, as much as 100 m above and northwest of previously known occurrences, while drilling has also intersected another native silver vein 95 meters (m) below and northeast of the first vein shoot. This gives the discovery a minimum potential 200-m vein zone vertical extent. It remains open in all directions as drilling continues.
Canada Cobalt Vice President of Exploration Matt Halliday stated, “It is now apparent from surface drilling that the initial discovery falls within a much broader and productive horizon associated with a 300-m-thick sill. This drill core is displaying textbook signatures of a Gowganda-style high-grade silver system, with extensive veining and alteration, native silver-filled fractures, and structures interpreted to be spatially related to high-grade mineralization.”
