Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.
Mine Description
The Emma mine is located in the N1/4 sec. 22, T. 20 N., R. 19 E. The mine workings consist of a shaft, supposedly 300 feet deep, sunk on a silicified zone along the contact between Mesozoic metamorphic rocks and Tertiary granodiorite porphyry. The mineralized zone strikes approximately N. 80° W. Pyrite and oxidation products thereof, occur as fine disseminations in a siliceous gangue. Reportedly, some gold and silver accompany the pyrite. The mine has been idle for over 50 years.
