This mine and prospect area are within the Wrangell-St. Elias National Park.
Location: Some placer gold mining and prospecting took place locally near the mouth of Falls Creek on Little Bremner River along active outwash of the glacier at the head of the river (Moffit, 1914). The mine is on the river at an elevation of about 1,325 feet in the NE1/4 section 25, T. 8 S., R. 5 E., of the Copper River Meridian. The location of mining is approximate, perhaps within 1 or 2 miles. It is locality 92 of Cobb and Matson (1972) and locality 71 of Winkler and others (1981 [OFR 80-892-B]).
Geology: Placer gold was discovered on Little Bremner River in 1901, and a little mining took place, mostly at the lower end of the active outwash plain of the glacier at the head of the river (Moffit, 1914). Drilling in 1911 showed that generally coarse gold was present in 7 feet of gravel above at least 40 feet of glacial mud. Bedrock in the general area is greenschist-facies metaflysch of the Late Cretaceous Valdez Group (Winkler and others, 1981 [OFR 80-892-A]). Gold-bearing quartz veins are widespread through the Valdez Group in the southern Valdez quadrangle (Cobb and Matson, 1972).
Workings: Some drilling and small-scale mining occurred in this area between 1901 and 1911 (Moffit,1914).
Age: Holocene.
