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): REFERENCES ON THIS PROSPECT ARE CONFUSING; REFERENCE BY JAMES, 1979, DESCRIBES CONTACT ZONE BETWEEN MISSISSIPPIAN LIMESTONE AND INTRUSIVES; HOWEVER, GEOLOGIC MAP SHOWS NO SEDIMENTS WITHIN ONE MILE OF PROSPECT. LOOKS LIKE THE MOUNTAIN LAKE MINE WAS BEING DESCRIBED RATHER THAN THEGREAT WESTERN MINE.

Comment (Workings): UNKNOWN EXTENT OF WORKINGS, HOWEVER THREE ADITS AND ONE SHAFT SHOWN ON THE MAP

Comment (Geology): PROSPECTS OCCUR NEAR INTRUSIVE CONTACT BETWEEN THE CLAYTON PEAK AND ALTA STOCK

Comment (Location): ANOTHER GROUP OF GROUP SMALL ADITS AND SHAFT LOCATED AT (UTM COORDINATES) 4493850 N, 451700E ; INFO FROM LAND.ST :1983

Comment (Development): WASATCH NATIONAL FOREST OWNS THE SURFACE RIGHTS

Comment (Commodity): REFERENCES ARE CONFUSING, THIS DATA MIGHT APPLY TO THE MOUNTAIN LAKE MINE
