Silver

This specimen is a cut slab of dolomitic breccia, richly impregnated with native silver. Both sides have been cut to reveal the intricate network of silver mineralization, with one side sealed in clear shellac. The piece displays a wealth of dendritic silver growths, fine silver veinlets, and native silver patches cutting through the brecciated dolomite host rock, a textbook example of Cobalt Camp ore texture and 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.
