Summary:Low-grade molybdenite and chalcopyrite mineralization occurs in a metasomatized ring structure in the westernmost part of the Galway granite in the Carna granodiorite around Lake Bunnacliffa. Molybdenite is structurally controlled along early quartz veins whereas chalcopyrite is more widely disseminated in the host rock. Induced polarization and resistivity techniques failed to locate these sulphides, but a magnetic exploration method was more successful, as was 40K radiometry. [R.A.H.]
