Comments on the location information

  • BLOCK 13, HOUSTON AND TEXAS CENTRAL RAILROAD CO. (THE BLOCK AND SECTIONS ARE ORIENTED NW-SE SO THAT THE DESCRIPTION GIVEN IS PRESENTED AS IF THE BLOCKS AND SECTIONS WERE ORIENTED N-S.) A SITE 84 IS GIVEN BY STROUD AND OTHERS (1970, P. 40) (USBM SAMPLE NO. RAF-78), IN NE OF SEC. 81, WITH 6 INCHES OF SHALE IN SAN ANGELO, ASSAYING AT 0.02% CU, BUT THE LOCATION IS NOT SPOTTED ON THE MAP. A SITE 85 IS GIVEN BY STROUD AND OTHERS (1970, P. 40) (USBM SAMPLE NO. RAF-79), IN SW SEC. 82, ON HARDWICK RANCH, WITH 6 INCHES OF SHALE IN SAN ANGELO, ASSAYING AT 0.40% CU, BUT NOT SHOWN ON MAP. GALLOWAY (1970, FIG. -) SHOWS THIS TO BE ABOUT 1500 FT WSW OF SITE 82 IN SE OF SW-SW OF SEC. 82.
