Comments on the geologic information

  • Geologic Description = Bottom Dollar Creek is about 7 to 8 km long and flows southward into Harrison Creek. The upper 3 km of Bottom Dollar Creek is underlain by Cretaceous chloritized porphyritic biotite monzogranite. Primary trace minerals include zircon, topaz, apatite and ilmenite. In the granite, anomalous gold concentrations are spatially associated with sericite-quartz occurrences (Wiltse and others, 1995). The coarse gravel along the lower part of the creek has been thoroughly mined. A pebble count of creek gravel near the mouth of the creek shows 77 percent quartzite, 13 percent quartz, and 10 percent mica schist (Yeend, 1991). Greenhorn Creek and Nugget Gulch are tributaries of Bottom Dollar Creek.? Small-scale mining on Bottom Dollar Creek was reported in 1909 to 1910, 1912, 1936, and 1938 to 1939, and sluicing occurred in 1975 (Eberlein and others, 1977, p. 18). Some small operations occurred in the 1980's and 1990. Most of the gravels have been processed for gold at least once (Menzie and others, 1983). Colledge Enterprises reported drilling on Bottom Dollar Creek in 1996 (Bundtzen and others, 1996).

Comments on the workings information

General comments

Subject category Comment text
Deposit Model Name = Placer gold deposit (Cox and Singer, 1986; model 39a)
Deposit Other Comments = Greenhorn Creek is a tributary of Bottom Dollar Creek, while Greenhorn Gulch is a tributary of Boulder Creek. Greenhorn Gulch is sometimes referred to as Greenhorn Creek in the literature and may lead to some confusion. Most information reported for Greenhorn Creek probably refers to Greenhorn Gulch, since Greenhorn Gulch was mined more extensively than Greenhorn Creek.
