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): NUMEROUS FISSURES ARE PRESENT ON THE PROPERTY, ALL WITH THE SAME GENERAL STRIKE AND DIP. MOST PROMINENT IS CALLED THE BROOKLYN AND IS THOUGHT TO BE THE BRAIN AND IS ACCESSED BY THE SILVER KING ADIT. OTHER FISSURES ARE THE SILVER KING, HOBOKEN, AND DAVENPORT. TWO DOMINANT TYPES OF MINERALIZATION ARE PRESENT, CONTACT METASOMATIC SKARNS AND REPLACEMENT BODIES NEXT TO FISSURES. CONTACT METASOMATIC DEPOSITS OCCUR IRREGULARLY NEXT TO THE OFF SHOOTS OF THE ALTA STOCK. REPLACEMENT BODIES PRODUCED LARGEST TONNAGE OF OARE AND ARE FOUND IN FAVORABLE BEDS NEXT TO ALL FISSURES. THE LARGEST REPLACEMENT BODY IS NEXT TO THE BROOKLYN FISSURE
Comment (Workings): MAJOR TUNNELS PRESENT ARE THE SILVER KING AND COPPER PRINCE TUNNELS. THESE TUNNELS FOLLOW AND DEVELOP NORTHEAST STRIKING FISSURES. CONSIDERABLE DRIFTING, WINZES AND RAISES ARE PRESENT. BESIDES MAJOR WORKINGS, A TOTAL OF 11 SHAFTS AND 9 ADITS ARE PRESENT ON THE PROPERTY.
Comment (Development): POSSIBLE EARLY PRODUCTION IN 1877 AND 1878. RECORDED PRODUCTION FROM 1911 TO 1919. MOST PRODUCTION FROM SILVER KING ADIT, EARLIER DEVELOPMENT FROM COPPER PRINCE ADIT
Comment (Commodity): SOME POSSIBLE EARLY PRODUCTION OF PB ORE. MINOR PRODUCTION OF MAGNETITE ORE IN 1919
Comment (Deposit): Discovery Year: LATE 1800'S
Comment (Geology): PALEOZOIC UNITS RANGE FROM TINTIC QUARTZITE TO DESERET LIMESTONE, ALTA STOCK IS JUST TO SOUTH. DIKES HAVE NORTHEAST STRIKE, BEDDING DIPS 20 TO 30 DEGREES TO EAST. GRIZZLY THRUST ZONE CUT BY ADITS
Comment (Location): UTM COORDINATES GIVEN ABOVE ARE FOR PORTAL OF THE COPPER PRINCE TUNNEL. COORDINATES FOR OTHER TUNNEL PORTALS ARE AS FOLLOWS, SILVER KING TUNNEL-4494010 N, 447535 E, UNNAMED PROMINENT TUNNEL-4494060N, 447700E ; INFO FROM LAND.ST :1983
Comment (Production): SOME PB ORE SHIPPED FROM SILVER KING ADIT IN 1905, 928 TONS OF ORE SHIPPED IN 1877 AND 1878 BY COMPANY WITH SAME NAME
