This is a relatively pure mass of Native Silver metal from the famous Cobalt Lake mine at Coleman Township, Cobalt-Gowganda region, Ontario, Canada. This very picturesque mine, but has not always been so as they had to drain the lake on numerous occasions. Started in 1906, it continued production through until 1943, eventually producing 6.9 Million ounces of silver. Miniature in size, this specimen weighs in at 36 g, most of which is silver metal. Its external surfaces are quite rounded, almost like a nugget, having lost its sharp hackly form at some point. It has a darker silver-grey colour, probably from age-related patina/tarnish. It is from the superb systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 & 1956-2021).
