Collector's Note: Discovery of an Exceptional Silver Vein in Michigan's Keweenaw Peninsula

Twenty-sixth in a series of articles on the mines and minerals of Michigan's Copper Country

ON 16 AUGUST 2017 an important discovery of a native silver vein located in Keweenaw County, Michigan, was made by Doug Miller of Calumet, Michigan. Miller, a thirty-year veteran of metal detecting in the “Copper Country,” has made several important discoveries of concealed copper/silver-bearing veins and has recovered tons of “float copper.” On this particularly warm, sunny day, he went back to an area about a half-mile northwest of the North Cliff mine.
