Comments

Comment (Deposit): THE COPPER JACK VEIN IS ONE OF FOUR VEINS THAT STRIKE ACROSS THE FLYING DUTCHMAN AND COPPER JACK PROPERTIES. TWO NEARLY ADJACENT MINES, DEVELOPED TOGETHER ON A 10-CLAIM PATENTED BLOCK OF LAND ORIGINALLY HELD BY COPPER JACK MINING AND MILLING COMPANY

Comment (Workings): THE PRINCIPAL WORKING IS A 140 FT. DEEP, VERTICAL SHAFT. ANOTHER VERTICAL SHAFT IS APPROX. 1200 TO 1300 FT. NORTHWEST OF THE COPPER JACK SHAFT, NEARLY ON THE EAST BANK OF THE STREAM BED IN SHEEPROCK CANYON. A 38 FT. DEEP, 66 DEGREE INCLINED SHAFT IS APPROX. 500 FT EAST OF THIS SHAFT

Comment (Geology): URANINITE HAS NOT BEEN POSITIVELY IDENTIFIED, BUT IS BELIEVED TO OCCUR IN DARK PURPLE, RADIOACTIVE FLUORITE PRESENT IN THE VEINS

Comment (Deposit): ACCORDING TO COHENOUR (1959, P. 117; 1963, P. 12), RADIOACTIVITY INDICATING AN ESTIMATED U3O8 CONTENT EXCEEDING 0.15%, IS PRESENT IN SOME FLUORITE-RICH SAMPLES FROM VEINS NEAR THE COPPER JACK SHAFT ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT

Comment (Production): SMALL AMOUNT OF PRODUCTION, RECORDED WITH OTHER PROPERTIES
