Comments on the location information

  • BLOCK 13, HOUSTON AND TEXAS CENTRAL RAILROAD CO. SURVEY. (THE BLOCK AND SECTIONS ARE ORIENTED NW-SE, AND THE DESCRIPTION IS GIVEN AS IF THE SECTION WERE ORIENTED N-S.) CORE B-3 (EL. 1631 FT; TD, 170 FT). COPPER AT 39.8-40.9 FT AND 163.9-164.7 FT. ALL ON 6666 RANCH. ABOUT 12 INCHES OF SHALE, DOLOMITE, GYPSUM, AND WOODY MATERIAL WERE COLLECTED (SITE 58, USBM SAMPLE NO. RAF-67) BY STROUD AND OTHERS (1970, P. 39). SITE 57, USBM SAMPLE NO. RAF-23, CAME FROM THE MILL TAILINGS. SITE 58 ASSAYED AT 10.60% CU. SITE 57 ASSAYED AT 1.95% CU. THE MINE WAS A SIDE-HILL CUT. THE MILL WAS CONSTRUCTED IN 1917. ABOUT 40 TONS OF ORE WAS SHIPPED OUT ON A CAR IN 1918, PURPORTEDLY FROM BENJAMIN, 17 MI TO THE NE.
