AbstractThe Atlin Integrated Geoscience Project, jointly funded by federal and provincial governments, entered its third and final year in 2002-2003. It is designed to advance understanding of the geological evolution and mineral potential of the northern Cache Creek terrane.
Project accomplishments for year three include 1) characterization of Cache Creek Group biostratigraphy and tectonostratigraphy; 2) new surficial geology map outlining placer potential in the Atlin area; 3) improved understanding of the age, composition, emplacement, and metallogenic potential of Mesozoic plutonic rocks; 4) better definition of the distribution and paleoenvironment of Neogene
volcanism; 5) delivery of a one-day workshop on magnetic surveying to prospectors and the general public. High-grade copper mineralization was discovered by personnel from the provincial survey. The discovery, named Joss'alun, is hosted within oceanic crustal rocks of the Cache Creek terrane. Mineralization appears concordant with the enclosing volcanic stratigraphy. If syngenetic, it establishes the terrane's volcanogenic massive sulphide potential.
