Comments on the geologic information

  • Geologic Description = Two large overlapping claim blocks staked in area. Block of nine claims staked in 1969 but apparently not active since. Block of 54 claims for unstated commodities staked in 1978 and active through at least 1981 (U.S. Bureau of Mines, 1980). No other information has been published, but see PE052 for a prospect within the site. . The geology of the area is dominated by the contact of Cretaceous quartz monzonite pluton with Cretaceous hornfels formed from graywacke of the Silurian Bay of Pillars Formation (Brew and others, 1984).
