Deposit OUTCROP
Deposit STROUD AND OTHERS (1970, P. 39, SAMPLE SITES 55-56, USBM SAMPLE NOS. RAF-13, RAF-20) IS MAIN REFERENCE. SMITH (1974, PL. IV-1, P. 59, 60, 68; IV-39, P. 69) IS ANOTHER REFERENCE WHERE HE MEASURED 56-59 FT ALONG ROAD. THE COPPER IS MALACHITE, IN THE BASAL SAN ANGELO FORMATION, IN SANDSTONE AND SHALE, ABOUT 7-10 INCHES THICK, AT ABOUT ELEVATION 1510 FT.
