Geology, geochemistry, and lead isotopic analysis of mineralization of the Strike property, Campbell Range, southeastern Yukon

The Strike property is located in the Campbell Range belt in southeastern Yukon. The study area is underlain by a wide variety of mafic volcanic and volcaniclastic rocks, as well as altered mafic intrusions and cherty metasedimentary rocks. Together these rock units are interpreted to comprise several discrete, relatively flat-lying and highly faulted lithologic assemblages. Lithogeochemical analyses of metavolcanic rocks that host mineralization on the property concluded that they are moderately enriched mid-ocean ridge basalts (E-MORB) to normal basalts (N-MORB) that likely formed in an ocean basin and/or back-arc/marginal basin setting. Diamond drilling intersected minor syngenetic, massive pyrite-chalcopyrite mineralization associated with hematitic chert/exhalite, as well as quartz-pyrite-chalcopyrite veining in a rubbly fault zone. Lead isotopic compositions of the mineralization are consistent with it being syngenetic Cyprus-type volcanogenic (VMS) mineralization. The results of the study highlight the potential for more Cyprus-type VMS mineralization in the Campbell Range in addition to the previously discovered Ice deposit and Money occurrence.
