Comments on the geologic information

  • Geologic Description = Geology in the immediate vicinity of the Bush prospect consists of one rhyolite and two porphyritic latite units intruding Precambrian to Paleozoic amphibolite-grade schist (Foster, 1976, Doyon Ltd., 1998). The rhyolite is highly siliceous and iron stained along fracture surfaces; hematite and pyrite are common trace accessory minerals. One porphyritic latite unit is light green and contains trace amounts of pyrite; the other unit lacks pyrite and is a darker green (Dashevsky, 1982). The region where the prospect is located lies within the Yukon-Tanana Y1 subterrane (Foster, 1970; Foster and others,1994). During soil sampling programs, low levels of lead and molybdenum were identified (Doyon Ltd., 1998).
  • Age = If the Bush prospect represents a porphyry Mo occurrence, its age is probably Late Cretaceous to early Tertiary, since there are other porphyry Mo deposits in the area of that age (Mosquito: TC015).
