The Berg 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.

Comments

Comment (Workings): CHAPIN (1916, P. 78) MENTIONS DEVELOPMENT WORK ON THE BERG CLAIMS IN 1915, BUT THIS REFERENCE MAY ACTUALLY BE TO A PROSPECT IN BERG BASIN, IN THE ADJOINING PETERSBURG QUADRANGLE.

Comment (Deposit): THE COUNTRY ROCKS IN THE GENERAL AREA OF THE BERG PROSPECT (KOCH, 1996, 1997) ARE MESOZOIC OR PALEOZOIC PELITIC SCHIST AND PARAGNEISS, AND SUBORDINATE AMPHIBOLITE AND MARBLE. AMBIGUOUS EARLY DESCRIPTIONS SUGGEST THAT THE PROSPECT IS AN AURIFEROUS LODE DEPOSIT. NO OTHER GEOLOGICAL INFORMATION ABOUT THIS PROPERTY HAS BEEN MADE PUBLIC.

Comment (Location): THE APPROXIMATE LOCATION OF THE BERG PROSPECT IS ABOUT 0.4 MILE WEST OF LOWER AARON CREEK AND 0.9 MILE EAST OF BERG CREEK, IN SECTION 24, AT AN ELEVATION OF ABOUT 150 FEET (COBB, 1978, LOC. 1; ELLIOTT AND KOCH, 1981, P. 7, LOC. 3). THIS LOCATION IS PROBABLY ACCURATE WITHIN ABOUT A QUARTER OF A MILE. ALSO SEE ADDITIONAL COMMENTS FIELD, BELOW.

Comment (Deposit): THERE IS LITTLE GEOLOGIC INFORMATION ABOUT THE BERG PROSPECT. EARLY REPORTS DESCRIBING IT (CHAPIN, 1916, P. 78; 1918, P. 75) INCLUDE REFERENCES TO THE COPPER KING PROSPECT (BC002). PARTS OF SOME OF THE EARLY DESCRIPTIONS OF THE BERG PROSPECT ARE AMBIGUOUS, AND MAY ACTUALLY REFER TO A DEPOSIT IN BERG BASIN, TO THE WEST IN THE ADJOINING PETERSBURG QUADRANGLE.

Comment (Exploration): Status = Inactive
