Capsule Geology

The Agnes (Davis 1) occurrence is located about 70 kilometres east of Dease Lake, just west of the Turnagain River.

The showing is hosted in an Alaskan-type ultramafic intrusive complex. This zoned complex consists of a dunite core and surrounding peripheral peridotites, pyroxene-rich peridotite, and olivine pyroxenite with maximum dimensions of 3 by 8.2 kilometres. This complex was intruded in the Late Triassic into Upper Paleozoic(?) and/or Triassic(?) metavolcanic and metasedimentary rocks of the Quesnel Terrane. It is in faulted contact on the east and north with slate and phyllite of the Ordovician to Mississippian Road River Group (Ancestral North America).

Sulphide concentrations occur in a medium grained, equigranular pyroxenite. Pyrrhotite and chalcopyrite occur as intercumulus blebs and pods, partially surrounding round to oval-shaped silicate grains less than 1 to 2 millimetres in diameter.

See the Turnagain prospect (104I 014) located 3.7 kilometres southeast for further details and history of this and other nearby showings.
