About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

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): Geologic Description = The country rocks in this part of Revillagigedo Island are mainly marine, andesitic or basaltic metavolcanic rocks and interbedded pelitic metasedimentary rocks that are intruded by Cretaceous sills and dikes of feldspar-porphyritic granodiorite, and by a stock of Tertiary gabbro (Berg and others, 1988). The strata and some of the granodiorite were regionally metamorphosed to greenschist grade in Late Cretaceous time, and subsequently remetamorphosed to hornblende hornfels near the contacts of the gabbro stock. The premetamorphic age of the strata is uncertain. Berg and others (1988) note that they closely resemble Upper Jurassic to mid-Cretaceous flysch and volcanic rocks nearby on Gravina Island. . According to U.S. Bureau of Mines claim records (1977), this prospect, which appears to be in metasedimentary rocks near the contact of the gabbro stock, was staked for copper and zinc. No other information about it has been made public.
