Geology and Mineralization of the Tog, Listwaenite-Hosted Gold Occurrence, Southern Yukon Territory

The TOG mineral occurrence is characterized by visible gold, low sulphide content and high gold grades associated with structurally controlled zones of intense carbonate alteration of the host ultramafic rock. The mineral occurrence is in a package of basalt, ultramafite and their altered and tectonized equivalents that structurally overlies a succession of carbonate and chert. Extreme carbonate metasomatism has altered the ultramafic rocks, producing listwaenite, a carbonate-silica-fuchsite alteration. High gold grades are restricted to the quartz veins and are not apparent in the listwaenite alteration.
