File 2008-03 presents a 1:50 000-scale geology map of the Chist Creek Map
area. Located 15 kilometres south of Terrace, in northwestern BC, the Chist
Creek map area is underlain by upper Paleozoic through Jurassic stratified
rocks of the Stikine assemblage and overlying Telkwa Formation, and is
intruded by Jurassic to Eocene intrusions.
The
area contains mineral showings of several types, including precious metal
veins such as the
Dardanelle prospect, redbed-copper style replacements such as
Treasure
Mountain, and – newly established in the course of 2007 mapping –
significant potential for volcanogenic massive sulphide deposits in an
extensive belt of Paleozoic rocks. These, called the Mt. Attree Volcanics,
are analogous to the host rocks of the
Tulsequah
Chief deposit in northern Stikinia. This geological map is the
third open-file release from the Terrace Project, which has been ongoing
since 2005. Previous maps included Open File
2006-3 and Open File 2007-4.
