DASH Deposits - A New Generation of Porphyry Targets in British Columbia
Porphyry deposits occur throughout much of British Columbia, as do epithermal deposits. Most of the porphyry deposits are late Triassic to Early Jurassic in age, and occur in the Stikinia or Quesnellia Terranes. This includes the largest deposits such as Mt. Milligan, Gibralter, Red Chris, Galore Creek, New Afton and Highland Valley.
Thor (and the nearby Max Mine) occur within rocks that are considered part of ancestral North America that occur west of the North American Craton. This includes basinal rocks that are for the most part sedimentary rocks, that are derived from the weathering of the North American Craton.
Absent from the map is the Max porphyry located just 8km southwest of Thor, and it occurs in largely sedimentary rocks to the east of the Stikinia and Quesnellia Terranes. We believe that this is prospective ground for B.C.'s next generation of porphyry deposits. DASH deposits are 'Deep Apex Sediment Hosted' Deposits, and geologically they are very different from the classic volcanic-hosted porphyry deposits found in the Stikinia and Quessnellia Terranes.
