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 (Workings): VERTICAL DEPTH OF OVER 1300 FT, 10 LEVELS NUMEROUS AMOUNT OF WORKINGS, AT THE END OF 1916 , 14,000 FT OF DEVELOPMENT WORK HAD BEEN DONE. IN 1927 FOLLOWING DEVELOPMENT WAS DONE; DRIFTS - 8,161 FT, RAISES - 4,667 FT, SHAFTS - 78 FT, DIAMOND DRILLING - 19,980 FT.
Comment (Deposit): CHARACTERISTIC FEATURES OF THE MINERALIZATION IS THE STREAKED APPEARANCE OF THE ORE DUE TO THE ARRANGEMENT OF SMALL SUB-PARALLEL BANDS OF CHALCOPYRITE AND BORNITE, THEY FOLLOW GENERAL DIRECTION OF ORE BODY.
Comment (Geology): GEOL.DESC: ENGEL MINE AREA IS A PART OF THE DIAMOND MOUNTAIN BLOCK, WIDTH OF 20 MILES, LENGTH OF OVER 50 MILES, THE BLOCK HAS A NW - SE TREND AND IS BOUNDED BY A PROMINENT ESCARPMENT ON EAST SIDE. PRINCIPAL ROCKS ARE PLUTONIC, VARYING FROM GABBRO-DIORITES TO TRUE GRANITES WITH ASSOCIATED DIKE ROCKS. OLDER PLUTONIC ROCKS, GABBRO, DIORITE AND QTZ. DIORITE ARE PART OF A LARGE BATHOLITH OF WHICH THE WESTERN BORDER APPEARS IN THE ENGELMINE AREA. OTHER PLUTONIC ROCKS OCCUR AS TWO STOCKS, ONE PREDOMINANTLY OF QUARTZ MONZONITE, WHILE THE OTHER IS A TRUE GRANITE. OLDER ROCKS ARE MORE BASIC, YOUNGER ROCK MORE ACIDIC. TWO TYPES OF PRE-PLUNTONIC, OLDER TYPE IS PREDOMINANTLY RHYOLITIC FORMING A SERIES OF TUFFS, YOUNGER TYPE IS AN INTRUSIVE ANDESITE PORPHYRY. THE AGES OF THE PLUTONIC ROCKS ARE SUGGESTED TO BE LATE JURASSIC, THE RHYOLITE AND ANDESITE PORPHYRY ARE SUGGESTED TO BE CARBONIFEROUS.
Comment (Deposit): 181 QUARTZ CLAIMS - SUPERIOR MINE IS PART OF THE OVERALL ENGEL MINING CO., BUT DUE TO ITS SIZE AND DIFFERENT GEOLOGY, IT WILL BE HANDLED IN ITS SEPERATE REPORT. COMPRISED OF 4640 ACRES.
Comment (Commodity): PYRITE IS RARE
Comment (Production): THE FIGURES IN THE TABLE ARE FROM THE ANNUAL REPORT FOR 1927. SAID TO PRODUCE IN 1918 ABOUT 9,100,000 LBS. OF COPPER
Comment (Deposit): MRDS RECORD W017598 HAS BEEN MERGED WITH THIS RECORD AND DELETED
