Location and accuracy This mine is on Kraemer Creek (sometimes spelled Kramer), a tributary to Limestone Creek. The main cut of the mine is near the northeast corner of section 3, T. 21 S., R. 16 E., Fairbanks Meridian, and is about 0.2 mile west of Trout Lake (Moffit, 1944). Kraemer Creek is combined with Limestone Creek (MH309) and Bedrock Creek (MH310) as locality 29 on figure 6 of Cobb (1979 [OFR 79-238]) and as locality 68 of MacKevett and Holloway (1977).

Geologic setting

Geologic description

Kraemer Creek is a half-mile long creek that flows on a broad bench on the west side of the Middle Fork Chistochina River. It is subparallel to and about one-quarter mile south of Limestone Creek. The Kraemer Creek mine developed auriferous gravels on a mile-wide bench on the west side of the Middle Fork Chistochina. Placer gold in the area is in small, flattened but dense nuggets. Gold on Kraemer Creek reportedly was somewhat coarser than on Limestone Creek (MH309). Some of the gold on Kraemer Creek occurred in grains that weighed about 0.02 ounce (Moffit, 1944). According to mine operator Martin Jasper (in 1941), heavy minerals in decreasing order of abundance were magnetite, pyrite, chromite, galena, and olivine (?). Platinum, native copper, and sparse native silver also occurred in the concentrates (Moffit, 1944).

Production and reserves

Workings or exploration Placer gold was found in Kraemer Creek at least by 1907 (Moffit, 1912, 1944). The Kraemer Creek mine was first included in the Cleveland group of claims, which later were incorporated in a group of 75 claims owned by the Middle Fork Mining Company of Seattle. The company conducted an extensive exploration program between 1934 and 1941 (Moffit, 1937, 1944). A large-scale mining operation begun in 1941 was terminated by World War II (Moffit, 1954).
Indication of production Undetermined

Additional comments

A possible low-grade gold resource exists on benches cut by Kraemer and nearby creeks (Moffit, 1944).
