In the course of removing mass copper from underground, miners would cut larger pieces of copper by hand with hammers and chisels, and in the process they would "chip" off small pieces of the copper. Many of these chips ended up on the waste rock piles and then buried by more material as it came out. Copper chisel chips, as they are known, can still be found in the piles with a little patience. This particular specimen was found in 2010 at the Central Mine located in Keweenaw County, Michigan. The specimen measures approx. 8 cm. across, making it a fairly large chip.
