Copper is a chemical element with the symbol Cu (from Latin: cuprum). It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color.
In certain parts of the state of Michigan, copper is found as pure copper metal rather than the copper oxides or copper sulfides found in most other copper mines. It is found here in Precambrian rocks, in sandstones, conglomerates, ash beds, and basalts.
