Agency: NF Region District: R1 Ranger District: JEFFERSON Forest Service Tract: Watershed Code: 10020005 Forest or Resource Area: DEERLODGE Owner: N Impact: Report: Nicholson (Ridgeway) This mine is current covered under an operating permit. Information in MBMG files and O'Neill and others (1983) indicates it may have a discharge, but the adit portals are located on a talus slope and water may percolate through the talus before surfacing. The mine contains some high grade pockets of gold ore (up to 9 oz/ton), and has produced at least 420 oz of gold since 1939 (O'Neill and others, 1983). Mineralization was probably localized by the Bismark fault zone, and country rock is tonalite of the Tobacco Root batholith near its fault contact with the Archean gneiss. A gravity concentration and amalgamation mill apparently existed on the property at one time (Reyner and Trauerman, 1949), but no trace of a mill or tailings could be found today. |
