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 (Commodity): A GENERAL LACK OF PGE-BEARING MINERALS SUGGESTS THE PGE ARE CONTAINED WITHIN OTHER MINERAL STRUCTURES. MINERALOGY IS ASSUMED TO BO THE SAME AS AT DRAKE MINE

Comment (Location): IN FLATHEAD INDIAN RESERVATION. LOCATION GIVEN IS SOUTHERN ADIT OF THE TWO SHOWN ON MAP FOR LUCKY STRIKE

Comment (Production): ORE WAS PROBABLY MINED FROM THE SURFACE

Comment (Deposit): 5 SMALL QUARTZ VEINS ARE EXPOSED IN AN OPEN CUT. DEPOSIT IS PROBABLY SIMILAR TO THAT AT DRAKE MINE. IT LIES NORTH OF DRAKE MINE WITHIN SAME DIKE; UNPUBLISHED MODEL NAME: REVAIS CREEK CU-AU-PGE.

Comment (Workings): 3 ACCESSIBLE ADITS IN 1963. NO STOPES OBSERVED IN WORKINGS

Comment (Geology): DIKE CAN BE TRACED FOR 8,000 FT ALONG REVAIS CREEK. ALTHOUGH THE DIKE IS NOT CALLED PART OF THE PURCELL SILLS IN THE LITERATURE, IT IS SAID THAT THE DIKE IS POSSIBLY RELATED TO SILLS LOWER IN THE BELT SEQUENCE

Comment (Deposit): RECORD DC11293 HAS BEEN MERGED AND DELETED. SEE ALSO: MRDS W026566.

Comment (Development): NEW DEVELOPMENT WORK BEGAN IN 1972 BUT ENDED IN THE MID 1970'S
