Aetna Mine facts: per Steven's Copper Handbook, Vol. V. Aetna operated from 1863 until 1873, producing a total of 144,881 pounds of refined copper.
IMO, most likely opened due to the doubling of copper prices with the onset of the Civil War. The sparse site is still viewable, if one is determined enough to make the trek.
