Hole DSB-12 664.64m to 671.63m. Deformed intrusion breccia locally intercalated with aphanitic dacite. Breccia is polymictic, clast-supported with subangular to subrounded clasts of fine-grained dacite in a milled granodiorite matrix, partially replaced by tourmaline. Mineralization is principally as three vein breccias consisting of pyrite, chalcopyrite, alunite and quartz. Locally there are sulphide veinlets (3-5 per m) and disseminated pyrite (3%).
