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 (Deposit): Other Comments = See MAS/MILS Sequence #0020200014 (USBM, 1995)

Comment (Workings): Workings / Exploration = A high grade sample contains up to 39.9% Pb, 23.94% Zn, 875 ppm Cu and 53.6 oz per ton Ag; stream sediment samples collected in this area by the U.S. Bureau of Mines are also anomalous in these elements (Meyer and Kurtak, 1992, p. 46-61).

Comment (Deposit): Model Name = Lode; sediment-hosted vein and breccia vein Pb-Zn-Ag.

Comment (Geology): Geologic Description = This occurrence is a north-south zone of quartz veinlets and quartz-cemented sandstone breccia float and rubble containing locally massive galena and sphalerite; and is located in an incompletely mapped area of folded and thrusted sandstone, siltstone, shale, and conglomerate of the Upper Devonian to Lower Mississippian Endicott Group.

Comment (Reference): Primary Reference = Meyer and Kurtak (1992)
