Deposit THE NAME OF THE DATA BASE WAS CHANGED TO CUYUNA NORTH RANGE INSTEAD OF CUYUNA RANGE IN ORDER TO BE SPECIFIC ABOUT THE AREA THIS DATA PERTAINS TO. THE MILS MAP NAME IS RIVERTON BUT CROSBY, TROMMALD, AND CUYUNA MAPS ALSO COVER THE MINE AREAS. ALL OF THESE MAPS ARE 7.5 MIN. QUADRANGLES. THE PLS ENTRY IS A GENERAL LOCATION OF THE MINE AREAS. THE AREA COVERS SECTIONS 3, 9, 10, 19, OF T 46 N R 29 W AND SECTION 33 OF T 47 N R 29 W. THE CAPACITY OF THE PLANT WAS 6400000 MTPY.
