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 (Location): LATITUDE-LONGITUDE VALUES CALCULATED FROM TOWNSHIP, RANGE, SECTION. Location modified by comparison of description (on switchback) with prospect symbol on Gasquet 7.5 topo map (1/30/2009).
Comment (Production): About One Ton Of 40-50 Percent Chromic Oxide Content Ore Has Been Mined. About 6 Tons Of Medium-Grade Ore Are Piled By One Of The Cuts; No Ore Is To Be Seen In Place.
Comment (Workings): Small Open Cuts.
Comment (Names): The original site name contained a derogatory word that has been changed according to Department of the Interior policy outlined at http://geonames.usgs.gov/docs/pro_pol_pro.pdf. See Chap. 3, Policy V. The revised form of the name now appears in the permanent record as the "Current" or preferred site name, and the prior, derogatory name is labeled "Previous".
Comment (General): Doug Causey - I combined information from DEP_ID 10284463 and deleted that record. The information was almost exactly the same between these two records.
