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): THORIUM VEINS IN THIS AREA ARE ONE OF FOUR ENVIRONMENTS OF TH OCCURRENCE KNOWN IN POWDERHRON-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. BLACK CANYON SCHIST AND GNEISS COUNTRY ROCK TRENDS GENERALLY NW, DIPS 35 TO 55 SW, AND IS INTRUDED BY COMPOSITE SYENITE INTRUSION. NORTH END OF BODY IS OFFSET BY FAULT TRENDING GENERALLY N 35 E, APPARENT RIGHT LATERAL MOVEMENT. PROSPECTS LIE AMONG TWO LEUCOSYENITE AND GRANITE DIKES (LATER PHASE) CUTTING PORPHYRITIC SYENITE AND TRENDING N 33 W AND N 27 W.
Comment (Workings): TWO SURFACE PROSPECT PITS
Comment (Geology): OTHER MINERALS LISTED ABOVE ARE GENERAL OCCURRENCES REPORTED FOR TH VEINS IN AREA; ALL MAY NOT NECESSARILY OCCUR AT THIS SITE.
Comment (Location): JUST SOUTH OF ROAD AND AT HEAD OF UNNAMED TRIBUTARY OF WOLF CREEK 1.0 MILE NNW OF LILLY BELLE MINE. ; INFO FROM LAND.ST :1975
