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 (Reserve-Resource): FIGURES ARE FOR COMBINED MONTGOMERY-SHOSHONE AND BULLFROG PITS-ABOUT A MILE APART.
Comment (Deposit): DURING UNDERGROUND MINING, MOST OF THE ORE PROBABLY CAME FROM ABOVE THE 300 FT LEVEL. THE BEST ORE FROM "GLORY HOLE" AREA, SOME OF WHICH REPORTED TO ASSAY $700/TON.
Comment (Location): NORTH SLOPE OF MONTGOMERY MOUNTAIN. . INFO FROM LAND.ST :(1972)
Comment (Commodity): THE RATIO AG:AU IS MUCH HIGHER THAN CHARACTERISTIC FOR BULLFROG DISTRICT ORES
Comment (Development): ACQUIRED BY ST. JOE IN 1982 AND EXPLORATION DRILLING BEGAN IN SEPTEMBER 1983. BY 1985 A MINERAL INVENTORY HAD BEEN DEVELOPED, METALLURGICAL TESTING WAS COMPLETED, AND AN OPEN PIT MINE WAS DESIGNED. ST. JOE PLANNED (2/88) TO BEGIN CONSTRUCTION IN JUNE, 1988, WITH PRODUCTION TO BEGIN IN MAY, 1989. IN APRIL 1988, 8 DRILL RIGS WERE ACTIVE ON THE PROPERTY IN PRE-PRODUCTION. EXPLORATION IN THE VICINITY BASED ON THE MONTGOMERY-SHOSHONE MODEL LED TO THE DISCOVERY OF WHAT BECAME KNOWN AS THE BOND GOLD BULLFROG DEPOSIT (RECORD #RE00023). ; ECON.COM: OPEN PIT MINE DEVELOPED IN CONJUNCTION WITH THE BOND GOLD BULLFROG MINE.
Comment (Workings): HISTORIC WORKINGS CONSIST OF 600 FT. DEEP SHOSHONE SHAFT AND 300 FT. DEEP POLARIS SHAFT WITH 9000 FT. OF WORKINGS. DEVELOPED AS AN OPEN PIT BY BOND GOLD.
