Comments
Comment (Workings): Workings / Exploration = Brief field examination and sampling. Sample (93TL 105c) yielded 20 ppb Au and sample 93TL 105b yielded 100 ppm Pb and 2,000 ppm Ba.
Comment (Geology): Geologic Description = Mineralization occurs in dark green to black andesite(?) containing minor amounts of sulfide minerals. Locally, volcanic rocks are brecciated, silica-cemented and contain druzzy quartz. Minor quartz stringers locally cut volcanic rocks. Exposure is is a quarry located on the contact between volcanic rocks and fine- to medium-grained hornblende granodiorite porphyry.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Tertiary
