Comments on the geologic information

  • Geologic Description = This prospect consists of a massive, sulfide-bearing, green-stained silica-carbonate-talc rock veined by quartz ; samples contain as much as 3.9 ppm Au, 1,000 ppm Ni, and 1,000 ppm Cr (Foster, 1968, p. 2, 10-11). A fire assay of one sample showed 5.6 ppm Au (Foster, 1968, p. 10-11). The nature of the contact between pyritiferous metasedimentary country rock and silica-carbonate-talc rock is not known (Foster, 1968, p. 2).
