520 |a“The Highland Valley District (HVD), the largest porphyry camp in Canada, has produced as of 2013, about 6.5 Mt of Cu with proven and probable ore reserves of 546.6 Mt @0.29% Cu and 0.008% Mo. The deposits are hosted by the Guichon Creek Batholith (GCB), a late Triassic calc-alkaline intrusive complex within the Nicola arc, Quesnel Terrane, of the Intermontane belt, southeastern British Columbia. The Nicola arc is also well known for hosting several Cu-Au porphyry systems, such as Ajax and Afton and Mount Polley, that are associated with latest Triassic to earliest Jurassic alkaline intrusions of the Copper Mountain plutonic suite. Despite the importance of the Guichon Creek Batholith as host to major copper deposits, modern geochemical analyses are lacking and little is known about the precise timing and duration of magmatism and mineralization, information critical to understanding its petrogenesis and relationship to the tectonic evolution of southern Quesnel Terrane. We present new high-precision U-Pb and Ar-Ar geochronological data, Nd isotopic data and high-quality geochemical analyses in order to evaluate: the temporal and petrochemical development of this batholith and its relationship to mineralizing systems; and constrain its larger scale tectonic context and relevance for porphyry deposit formation and distribution in general”--Introd., p. 7.
