Comments on the geologic information

  • Geologic Description = Exploration workings have been dug on quartz-stibnite veinlets at this locality. This prospecting was first reported by Smith and Eakin (1911) who noted this as a small occurrence with a trace of gold; limonite staining on joints and fractures was idenitified but no distinct vein or lode was observed. Sampling of dump materials by Miller and Grybeck (1973) confirmed the presence of stibnite (greater than 10,000 ppm Sb) but gold was not detected. The early exploration workings prior to1909 included a 25-foot-long trench and a 100-foot-long adit (Smith and Eakin, 1911). Bedrock is metasedimentary rocks that include lower Paleozoic calc-schist (Till and others, 1986). The metasedimentary rocks are on the east flank and within 0.4 miles of the Darby pluton but thermal metamorphism has not been described. High angle faults may be important structural elements in this area.
  • Age = Not known; probably mid-Cretaceous, the age of the nearby Darby pluton (K/Ar ages for the Darby pluton are 88.3 +/- 1.5 and 92.8 +/- 2.6 Ma, Berry and others, 1976), or younger.
