THE COPPS MINE is located in sections 14, 15, and 22, T47N, R43W, in Upper Michigan's westernmost county of Gogebic, and approximately 9.8 kilometers north (N17°E) of Marenisco, the nearest community (fig. 3). The “mine” (more aptly described as an exploration) was developed in the 1880s to test the value of argentiferous galena showings discovered along a prominent ridge in the area and is named after Edward J. Copps, a Canadian businessman of Irish ancestry who settled in Michigan's Upper Peninsula in the 1880s and began prospecting mineral lands (Cox 2007).
