Silver

The piece is and richly impregnated with native silver, which can be seen coursing through and infilling the brecciated dolomite host rock. It has been cut smooth on one side and left rough on the other, allowing the silver to be clearly visible from both faces. A textbook example of classic Cobalt Camp ore mineralogy.

The Silverfields Mine, located in the heart of the historic Cobalt mining district, was one of the camp’s most notable and last-producing operations. Active from 1963 to 1983, it represented the final era of large-scale silver mining in Cobalt and produced exceptionally high-grade native silver. The deposit consisted of calcite–dolomite breccia veins enriched with native silver and cobalt-nickel arsenides, characteristic of the region’s world-famous ore style.

Specimens from Silverfields are now increasingly scarce, making this a superb, high-grade example from one of the Cobalt Camp’s historic and final producing mines, a tangible piece of Canada’s silver mining legacy.
