Geologic setting

Geologic description

Gold has been found in in the lower 3 feet of gravel and on bedrock (Overbeck, 1920, p. 181; Mertie, 1918). Bedrock is mainly chert but there is some granite at the mouth of the second tributary above Livengood Creek. Basalt porphyry is the bedrock at the head of the creek; there is limestone and argillite near the mouth (Mertie, 1918).
Bench gravels were mined east of the creek in 1918, to a depth of 25 to 100 feet, above a pay streak of 40 to 60 feet wide (Overbeck, 1920, p. 181). Concentrates of these gravels contain magnetite, limonite, hematite, chromite and pyromorphite. Joesting (1942, ATDM Pamph. 1) reported that the chromite and chrome spinel in placers was probably derived from serpentine in Middle Devonian basic volcanic rocks. Mining occurred in 1916, 1922, 1924, 1926, 1928-1939, 1967-1968 (Cobb, 1976; OFR 76-633, p. 9).
