A former small surface Pb-Cu-Zn-Au-Ag mine located on the 7250 contour of Miller Canyon in sec. 27, T23S, R20E. Started in the early 1880's. Produced 1914-1915. A little ore was sent from this, and other, properties to lead smelters at Charleston and Benson. Field observations indicate that this was strictly a prospect. The existence of a road the length of Miller Canyon to the mine and the presence of a large ore bin at the top of the mountain are inconsistent infrastructure for the size of the workings and this condition is indicative of a possible mining stock scheme.

Mineralization is a vein deposit, 0.61 meters wide, striking N5W and dipping 65NE. Alteration is skarn.

Local structures include exotic blocks of Paleozoic sedimentary rocks within Jurassic volcanic rocks. A NW-trending thrust is mapped approximately 100 yards (96 meters) west of the workings.

These workings are located near the top of Miller Canyon and were re-discovered accidentally by Mr. Parsons & a friend. The name of Miller Canyon is commonly recognized but it is a collectors' name and a misnomer since the actual mine is at the head of the canyon at Miller Peak. One must hike through Miller Canyon to get to the locality. It was originally the Holenstein mine (1880's). Reaching this locality is a chore since it requires an approximate 3 mile (5 km) hike, gaining approximately 1,500 feet (450 meters) of altitude, through a wilderness area (no motorized transport allowed). The locality is often snow-covered. Collecting is hard work and anything collected must be carried out.
