|Location and accuracy||This occurrence is on the north side of North Fork, Mosquito Creek at an elevation of approximately 1,250 feet. Mosquito Creek flows westward from headwaters in the northern Darby Mountains to Telephone Creek, a tributary to Fish River in McCarthy's Marsh. This location approximates sample locality 7 of Miller and Grybeck (1973). It is location 52 of Gamble (1988).|
Geologic descriptionMiller and Grybeck (sample 7, 1973) collected a grab sample of gossan developed at a marble/schist contact at this locality. This sample contained 7,000 ppm As, 700 ppm Cu, 70 ppm Mo, 3,000 ppm Pb, 10,000 ppm Sb, and 10,000 ppm Zn. These occurrences are in Lower Paleozoic or Precambrian high grade metasedimentary rocks (Till and others, 1986).
