Comments on the geologic information

  • Geologic Description = Soil samples of the Friden prospect show anomalous molybdenum on the ridge, and weakly anomalous gold in stream-sediment samples. The area is underlain by amphibolite-grade schist country rock that has been intruded by Tertiary (?) quartz monzonite, diorite, rhyolite porphyry and rhyolite breccias, and minor olivine basalt. The granitic rocks also appear to contain high levels of fluorine (Doyon Ltd., 1998).
  • Age = Tertiary

Mining district

District name Fortymile

Comments on the workings information

  • Workings / Exploration = In 1979 WGM Inc. conducted a soils reconnaissance program for molybdenum. In 1981, Arctic Resources Inc. conducted a follow-up investigation of high-value soil samples, and in 1984 Doyon Ltd. briefly examined a fluorine anomaly. In 1985, Doyon Ltd. reanalyzed samples containing anomalous gold values. In 1990, stream sediments were sampled for gold by Doyon Ltd., and in 1991, stream sediments, rocks, and soils were sampled.
