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 (Geology): Molybdenite occurs in quartz-pyrite veins and silicified shear zones in quartz monzonite porphyry at the Nye mine; moly content may range up to several percent in some parts of the veins.

Comment (Location): The property is in northern Gilpin County, about 1 mile ENE of Apex, on Dakota Hill, secs. 15-16, 22, T 2 S, R 73 W.

Comment (Production): Nye Metals, Inc., contracted with the Office of Mineral Exploration (OME) and received funds to exploration for moly in 1962; a few thousand tons production of high-grade molybdenum ore was reported in 1964-65 from the Wilma (Nye) mine.

Comment (Deposit): THIS RECORD DUPLICATED MRDS # DC03801, DC05686, AND D000432. THE RECORDS WERE COMBINED AND WERE DELETED.
