Geologic setting

Geologic description

Color anomaly 3,000 by 2,000 ft (900 by 600 m) elongate along a northeast trend. Country rocks are marine clastic sedimentary rocks and andesite flows and breccias cut by diorite and feldspar porphyry dikes. Pyrite is disseminated in weakly altered diorite dikes and occurs along fractures and disseminated in the country rocks.
