Hidden Treasure Mine, Castle Mountains District, Meagher County, Montana
Not much is known about the Hidden Treasure. The mine reportedly produced oxidized ores in the 1890's. Development consists of a few shallow shafts and pits. The main workings are driven along the contact between limestone and an intrusive. The limestone has largely been altered to the normal Ca-silicates. Some decent grossular and rare epidote have been recovered from the mine. Interestingly, the epidote is always found with Japan law twins.
Looking towards the south across the Hidden Treasure mine site. The main shaft and its overgrown dump are in the center of the picture. The remains of wooden horse whim lie to the right of the shaft.
