Project Information

  • Ore Deposit: Porphyry
  • Commodity: Copper, Gold
  • Research Themes: Regional Metallogeny
  • Location: Iskut-Stikine River region, British Columbia
  • Project Status: Completed
  • Start Date: 2014

The Mitchell Cu-Au-Ag-Mo porphyry deposit in the Stikine terrane of northwestern British Columbia together with the Kerr-Sulphurets-Mitchell porphyry deposits (KSM) are amongst the largest undeveloped gold-rich porphyry resource in Canada. These deposits, along with the Brucejack high-grade gold deposit and the Snowfield porphyry deposit are hosted in volcanosedimentary rocks of the Late Triassic Stuhini Group and unconformably overlying Early Jurassic volcanosedimentary strata and allied plutonic rocks of the Hazelton Group. Part of the Sulphurets district, these deposits lie at the northern end of a 60-km-long north-northwest trending Cu-Au porphyry and related mineralization.

The Mitchell deposit porphyry-related mineralization has been studied for over 50 years but detailed deposit-scale documentation has hitherto been lacking. New field, petrographic, geochemical, and geochronologic data to document relationships between sedimentation, plutonism, alteration, vein paragenesis, mineralization, and deformation are evaluated and presented within this project.
