Location: Sirr Creek is a south-flowing tributary of Seward Creek that is about 2 miles west of Wild Lake. As described by Reed (1938), Sirr Creek was known as the North Fork Seward Creek in the 1930's and only the eastern fork was called Sirr Creek. This location of the workings is uncertain and the mine is arbitrarily plotted on Sirr Creek at an elevation of about 1,750 feet.
Geology: Reed (1938) reported that there was extensive prospecting and a little placer mining on Sirr Creek in the early 1900's. The rocks in the area are Devonian phyllite and schist (Chipp, 1972). No other information is available.
Workings: Prospecting and a little mining.
Age: Quaternary.
