Comments on the geologic information

  • Geologic Description = This prospect consists of heavy minerals, including gold, in wave-formed beach placer deposits. Zones of heavy-mineral concentration in the sand can reach three feet thick. One such one-foot-thick zone overlying pebbles of felsic intrusive rock, greenstone, graywacke and slate was sampled and contained over 10% garnet (Jansons and others, 1984). Two 0.1 cubic-yard samples of the beach sand contained <0.03 ppm to 0.0002 oz. Au/ton.
  • Age = Holocene.
