Geologic setting

Geologic description

In 1920, a lode prospect was staked over a pyroxenite dike in limestone, which was uncovered in upper Hidden Creek (see MD066). According to Brown (1926), gold and copper carbonates are present. The Matthews and Blackburn vein lies within the pyroxenite dike, which is composed predominately of augite. The dike intrudes the Ordovician Telsitna Limestone formation (Dutro and Patton, 1982).
