Comments on the geologic information

  • Geologic Description = Miller Creek is approximately 8 km in length and empties into Mammoth Creek about 2 km below the mouth of Mastodon Creek. The upper part of Miller Creek is underlain by the Middle Schist and Quartzite unit described by Wiltse and others (1995) as fine- to medium-grained quartz-muscovite schist, porphyroblastic albite-quartz-chlorite-muscovite schist, and lesser amounts of quartzose porphyroblastic albite-chlorite-schist. The lower part of the creek, including the confluence with Mammoth Creek, is underlain by the Lower Schist, a unit consisting of slightly calcareous quartz-muscovite schist, prophyroblastic albite-quartz-chlorite-muscovite schist, and lesser amounts of quartzose, porphyroblastic albite-chlorite schist and chlorite schist. Tertiary biotite granite crops out in the lower one half mile of the creek (Freeman and others, 1988).? In the lower valley, gravel thickness is 2 to 3 meters and overlying muck is 1 to 2 meters thick. Clasts in Miller Creek gravel are subangular to well-rounded and are as much as 1 meter in diameter (Yeend, 1991). Locally, a 1 meter thick bed of clay is present at the base of the gravel (Mertie, 1938). Most gold was recovered from the lower meter of gravel and at the gravel-bedrock contact in a width across the valley ranging from 15 to 20 meters. The gold formed fine flat scales and only a few nuggets weighing as much as 1 ounce were recovered (Mertie, 1938). Analyses of two sets of 7 assays gave weighted mean values of fineness of 832 Au and162 Ag, and 838 Au and153 Ag (Mertie, 1938).? Placer gold was mined intermittently from 1895 to 1940 but there are no data on production (Cobb, 1976, p. 47, [OFR 76-633]). Hydraulic mining was common throughout the district in the middle 20th century and only the thin, muck-covered, low-grade gravel was left unmined. In the early 1980's, only one mining operation was active near the mouth of Miller Creek. That operation involved thawing and moving a 10 meter thick section of gravel (Wilkinson, 1984).
