Mineral Specimen #5032 Native Copper in Kingston Conglomerate (Acrylic Coated)
Kingston Mine, Copper City, Keweenaw Co., Michigan
An end cut of a relatively large piece of Kingston Conglomerate which has been cut on one side and along one edge and then coated with a two part epoxy used for bar counter tops (contains a UV inhibitor to prevent yellowing). The Kingston Mine was opened in 1964 and was the last new mine opened in the Keweenaw peninsula and closed soon after in 1968 when mining ceased in the area. The Conglomerate was the ore from the mine and was distinctive from the other Keweenaw conglomerates in having small black spots and bright red color. Some of the cementing sandstone/quartzite has been replaced with native Copper.
