Show ( Placer-mining Placermining ) activities 43 have decreased until ( evi- evi ) dence indicates that probably there are less than five men working bars along the ( 540-mile 540mile ) stretch between Green River , Utah , Moab , Chinle Creek , and Lees Ferry . Witnesses for the State showed mineralization and some attempt to ( develop evelop ) coal , copper , uranium , vanadium , and manganese in the La Salle , Abajo , and Henry Mountains and in the region between Green and Colorado ( Eivers Rivers ) . With one or two exceptions , especially in the La Salle Mountain region , testimony showed that operations ( were ivere ) of an exploratory nature and that little actual development had taken place . Government Exhibit No . 638 , pages 608 to 640,1 U . S . Geological Survey Bulletin No . ( Ill 111 ) , entitled ( "Ore Ore ) Deposits of Utah , " discusses authoritatively the mineralization of the region . With respect to the La Salle Mountains area the report states that between date of first mineral locations in 1888 and 1917 when the Big Indian mine was opened , ( prob prob- prob ) ably 5,000 would cover the entire output of quartz and placer mining . In discussing the copper ( de- de ) posits at the Big Indian properties the report ( page 615 , Exhibit 638 ) states ( "Some Some ) good ore has . been ( found ound ) but the richer grade is in small bodies and would be difficult to mine without mixing with poor ore or waste . The great bulk of the ( mineral- mineral ) ized rock carries a ( rather rat4er ) low percentage of copper , and much of the ( low-grade lowgrade ) ore occurs in thin lenses and is difficult to extract without breaking barren 06891-30 |
