Comments on the geologic information

  • Geologic Description = The brief description of this prospect provided by Brosgi and Reiser (1972) indicates only anomalous gold and silver values in samples from a vein described as a single, thin, arsenic-rich vein in a system of east-west-trending quartz veins. The samples returned values as high as 3.6 ppm Au; Ag values were 1 to 3 ppm. Brosgi and Reiser (1972) also note several additional weakly anomalous rock and soil samples in an area which extends several miles to the southwest of the principal occurrence. The area is mapped as dark gray to black, gray to reddish-brown weathering, quartz-muscovite schist (Brosgi and Reiser, 1964).
