M262 Copper

M262 Copper


Here is a nice specimen of natural Copper from Keweenaw Peninsula, Michigan. This is natural native copper which has been removed from most of the matrix rock which was surrounding it.  It is the natural native copper just as it formed in the rock.  It measures approximately 4 1/4″ x 2 1/4″ x 2″ and weighs nearly 1.5 pounds. Although it looks like 2 separate pieces it is a single solid specimen.
