NATIVE Copper with Quartz$450.00

Kearsarge mine, located between Calumet and Allouez in Houghton County, Michigan, opened in 1886 and worked the Kearsarge Lode successfully for over a decade before being taken over by the Osceola Consolidated Mining Company who split it into two separate operations (North and South). Both mines closed in 1930/1931 but North Kearsarge reopened during the Second World War and had one final flourish of activity from 1942 to 1956. Known primarily as a source of some of the richest Native Silver specimens in the district, it also produced some very nicely crystallized Native Copper specimens. This cabinet-sized specimen is very well crystallized, albeit with smaller (2 to 3 mm) crystals. These crystals are equant and extremely well-defined, and having the blend of rich Native Copper dispersed through white vein Quartz provides a wonderful contrast. The Native Copper displays a fine old-time patina with one area showing a coating of malachite. Ex David Hardman collection, no. 3433.
