Satelite View

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 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 BLACK CANYON SCHIST COUNTRY ROCK TRENDS GENERALLY N 70 E, 70 TO 90 NW, AND IS CUT BY FAULT TRENDING N 56 W, A PORTION OF WHICH HAS BEEN MAPPED AS QUARTZ VEIN ON WHICH PROSPECTS DEVELOPED. EXTENSIONS OF FAULT ARE COVERED BY OLIGOCENE TUFFS.
Comment (Workings): SIX 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.
