Silver

A striking slab specimen cut on one side to reveal rich native silver mineralization within a carbonate vein section, while the reverse has been left natural and rough. Rounded silver beads can be seen penetrating the matrix through to the rough side, illustrating the high silver content and complex vein structure of this occurrence.

The specimen represents a cross section of a carbonate vein showing both wall contacts and abundant native silver intergrown with nickel arsenides, characteristic of the silver–cobalt mineralization style that made the Cobalt–Gowganda district world-famous.

The Bailey Mine, located on the west shore of Glen Lake, is geologically part of the same vein system as the adjoining Penn-Canadian Mine, and the two are often collectively referred to as the Glen Lake Mine. One of the older producers in the district, the Bailey Mine was reactivated in the 1960s and operated until its closure in 1971, with a total production of roughly 7 million ounces of silver. The workings included four shafts reaching a maximum depth of about 455 feet, along with an adit.
