Copper Mine Osceola #13

Big Inch
Copper Mine produced native copper but closed in the early '60's. I found lots of copper metal samples and even a small silver nugget while playing there in the rock piles many years ago. #Calumet #Copper #Copper_Country #Laurium #Michigan #Mine #native_copper #Osceola #UP #Upper_peninsula
