|Location and accuracy||The Mathews and Blackburn prospect is located at an elevation of 1,200 feet (366 m), one mile (1.6 km) east of Hidden Creek in Section 29, T. 26 S., R. 22 E., of the Kateel River Meridian. Location is imprecise and based on description by Martin (1922) and Brown (1926).|
Geologic descriptionIn 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).
