A copper-gold mine located on Montana Creek that worked a mineralized quartz vein in siliceous diorite country rock. Development includes a 85' adit and 2 other adits. It produced ore in 1915.
Structure: The Fawn Peak Stock Was Probably The Intrusive Rock Core Of An Island Arc (Riedell, 1979).

Geology: The montana deposit is in the cretaceous fawn peak stock. It is an elongate, northwest-trending intrusion along the northeast side of the methow river valley; it is situated along the axis of the goat peak syncline (stoffel and mcgroder, 1990).

Ore(s): The Deposit Consists Of Veins In The Actinolite Alteration Zone Of The Mazama Porphyry Molybdenum System (Riedell, 1979).
