The Perseverance Mine is a gold mine located in Alaska.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
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.

Land Status
Land ownership: National Forest
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments
Comment (Deposit): PART OF ALASKA JUNEAU LODE SYSTEM; NETWORK OF QUARTZ VEINS AND STRINGERS IN ZONE ABOUT 800 FT WIDE IN PERSEVERANCE SLATE; QUARTZ VEINS CONTAIN 1.5-2.0% SULFIDES, INCLUDING PYRRHOTITE, GALENA, SPHALERITE, PYRITE, RARE CHALCOPYRITE, AND ARSENOPYRITE
Comment (Workings): DEVELOPED 1915-1921 AS PART OF VERY LARGE SCALE OPERATIONS OF THE ALASKA GASTINEAU MINING CO.; DEVELOPMENTS INCLUDED 2500 FT ALEXANDER CROSSCUT, 12,000 FT SHEEP CREEK ADIT, 3 HYDROELECTRIC PLANTS AND 6000 TPD MILL; MINE WAS LATER CONNECTED TO A.J. MINE
Comment (Geology): SEE COMMENTS: ALASKA-JUNEAU. MT. JUNEAU PLUTON; PART OF COAST RANGE INTRUSIVE COMPLEX TO THE NE
Comment (Deposit): SEE ALSO: ALASKA-JUNEAU MINE; SOME DATA COMBINED FOR A.J., PERSEVERANCE AND EBNER AS THEY ARE ALL ON THE SAME LODE SYSTEM; REASONS FOR FAILURE OF ALASKA GASTINEAU LARGE SCALE, LOW GRADE ENTERPRISE: 1. OVERLY OPTIMISTIC INITIAL ESTIMATE OF GRADE, 2. UNCONTROLLED DILUTION OF ORE BY CAVING OF WASTE ROCK IN THE STOPES, 3. LABOR SHORTAGE AND INCREASE IN OPERATION COSTS DUE TO WWI, AND 4. REDUCED MILL EFFICIENCY DUE TO INTRODUCTION OF WET ORE INTO DRY-CRUSHING SYSTEM, USGS OFR 60, P. 19 ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
Comment (Commodity): AU STRONGLY ASSOCIATED WITH SULFIDES, ESP. SPHALERITE; AU: AG RATIO 1:1

Comment (Production): GOLD AT 20.67 DOLLARS/FINE OZ; UNKNOWN AMOUNT OF PRODUCTION 1895-1907; PRODUCTION FIGURES DO NOT INCLUDE LESSER AMOUNTS OF SILVER, LEAD AND ZINC; PRODUCTION FROM 1934 TO 1944 INCLUDED AS PART OF ALASKA-JUNEAU MINE, SEE: ALASKA-JUNEAU
Comment (Development): STAKED 1885; LARGE SCALE DEVELOPMENT BEGAN IN 1915 UNDER ALASKA GASTINEAU MINING CO.; MINE CLOSED 1921 DUE TO LOW GRADE ORE; ACQUIRED BY ALASKA JUNEAU GOLD MINING CO. IN 1933; OPERATED AS PART OF A.J. MINE FROM 1934-TO MINE CLOSING IN 1944; SEE COMMENTS FOR ALASKA-JUNEAU; 10 PATENTED LODE CLAIMS
