Comments on the geologic information

  • Geologic Description = The country rocks in the area of this prospect are deformed and metamorphosed Lower Cretaceous and Upper Jurassic turbidites (Wilson and others, 1998) cut by Lower Tertiary to Upper Cretaceous(?) diorite and quartz monzonite (Smith and others, 1988). The deposit is in metasedimentary and altered intrusive rocks, and consists of widely-spaced zones of disseminated molybdenite. This deposit probably is related to other porphyry-type deposits in the Gold Hill area (HE172 and HE173).
  • Age = Probably Late Cretaceous or younger.

Economic information about the deposit and operations

Development status Prospect

Comments on exploration

  • Status = Inactive

Mining district

District name Valdez Creek

Comments on the workings information

  • Workings / Exploration = This prospect has been explored by soil sampling and trenching. At least two shallow drill holes totaling 220 feet, were completed in the 1970's (D.L. Stevens, oral communication, 1999). Geophysical exploration has included a regional aeromagnetic survey over the prospect and surrounding area, as well as ground magnetics, IP, and EM.
