Abstract: In the inaugural year of the joint Geological Survey of Canada - British Columbia Geological Survey Branch - Yukon Geology Program Ancient Pacific Margin NATMAP project, substantial progress was made in documenting the nature of Yukon-Tanana Terrane in Yukon and northern British Columbia and how the different parts may have been linked paleogeographically. When ca. 425 km of displacement on the Tintina Fault are restored, the Finlayson Lake massive sulphide district lies north of and along strike from the Glenlyon and Wolf Lake - Jennings River study areas.

Stratigraphic sections from the component study areas illustrate similarities and differences along strike; both the similarities and differences with the Finlayson Lake stratigraphy affirm the potential of this belt to host volcanogenic massive sulphide mineralization.
