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.

Comments
Comment (Commodity): Small mines. Mainly gold.
Comment (Geology): Geology is similar to the Crestone district, which is located a few miles to the northwest (Vanderwilt, 1947). Also similar to mineralization at the San Luis mine in the El Plomo district, Costilla County, Colorado (Benson, 1997). Structurally controlled veins cut Paleoproterozic rocks.
Comment (Geology): Low-angle "detachment" fault present in district and hosts mineralization locally. Fault dips 25-30 degrees SW (Benson, 1997).
Comment (Geology): Gold associated with silicification and fine-grained pyrite mineralization along a low-angle fault structure (Benson, 1997).
Comment (Location): District is elongated along the western base of the Sange de Cristo Mountains. Located south of the town of Crestone and north of the Great Sand Dunes.
Comment (Production): Production is small.
Comment (Reserve-Resource): Resources have not been calculated.
