Comments
Comment (Workings): Workings / Exploration = A single sample of the sandstone collected during brief U.S. Geological Survey reconnaissance studies in 1993 yielded 120 ppm Cu, 110 ppm Zn, and 4 ppb Au. Volcanic rock samples yielded 4 ppb Au (93TL 102c) and up to 120 ppm Zn (samples 93AWs 12 and 13).
Comment (Geology): Geologic Description = Fine-grained lithic sandstone of the Andrew Lake Formation overlies volcanic breccia and massive flows(?). A linear, possibly a fault, extends northeast (about N 20xE) from the locality. Other samples of volcanic rocks collected in the vicinity of this linear were also weakly anomalous in Zn and Au.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Tertiary
