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): ON DIVIDE BETWEEN UNNAMED TRIBUTARIES OF CEBOLLA CREEK 2.0 MILES ENE OF DUBOIS MINE. ; INFO FROM LAND.ST :1975
Comment (Geology): OTHER MINERALS LISTED ABOVE ARE GENERAL OCCURRENCES REPORTED FOR TH VEINS IN AREA; ALL MAY NOT NECESSARILY OCCUR AT THIS SITE.
Comment (Deposit): THORIUM VEINS IN THIS AREA ARE ONE OF FOUR ENVIRONMENTS OF TH OCCURRENCE KNOWN IN THE POWDERHORN-IRON HILL AREA AND ARE PROBABLY RELATED TO EMPLACEMENT OF LATE PRECAMBRIAN SYENITES NORTH AND WEST OF IRON HILL AND OF YOUNGER LATE PRECAMBRIAN OR CAMBRIAN CARBONATITES AT IRON HILL. FOLIATION OF DUBOIS GREENSTONE COUNTRY ROCK TRENDS VARIABLY N 25 TO 85 W, REPRESENTING MAJOR CHANGE IN TREND FROM OTHER PROSPECTS IN DUBOIS MINE AREA DUE TO TWO INTERSECTING FAULTS TRENDING N 62 W AND N 15 E THAT DISPLACE SECTION. NE-TRENDING FAULT ALSO CUTS APOPHYSIS OF POWDERHORN GRANITE EXTENDING NE FROM MAJOR BODY. TH PROSPECTS LIE ON TWO QUARTZ VEINS TRENDING N 15 E AND N 45 E, 40 SE. THIRD QUARTZ VEIN TRENDS N 27 E AND MAY CONTAIN BASE-METAL SULFIDES THAT ARE ALSO KNOWN TO OCCUR IN VEINS.
Comment (Workings): FIVE SURFACE PROSPECT PITS
