Location: Ester Creek is a short, west-flowing tributary to Dollar Creek, which is a headwater tributary to Beaver Creek. The coordinates are for the mine symbol marked on the U.S. Geological Survey Ophir A-2 topographic map (1954, minor revisions 1965). The symbol is near the midpoint of Ester Creek, in the SE1/4 sec. 29, T. 28 S., R. 12 E., Kateel River Meridian. Ester Creek is locality 11 of Cobb (1972 [MF 367]).
Geology: The drainage area of Ester Creek is underlain by undivided Cretaceous clastic rocks. The headwaters also drain several small, Cretaceous or Tertiary dikes and subvolcanic plutons (Chapman and others, 1985). The gold in Ester Creek is 841 fine according to Metz and Hawkins (1981). Mertie (1936) reports a fineness of 836 gold and 156 parts silver. Gold was being mined in 1926, and it was probably mined earlier (Holzheimer, 1926 [MR 64-1)]. Mertie (1936) reports mining in 1933, and Bundtzen and others (1987) indicate mining sometime during the 1980's. Production from Ester Creek between the early 1900's to 1964 was 1,110 ounces of gold and 210 ounces of silver. Production figures for Ester Creek from 1980 to 1986 are unavailable (Bundtzen and others, 1987). Also see OP028.

Age: Quaternary. The source of the placer gold is probably Cretaceous or Tertiary intrusive rocks (Bundtzen and others, 1987).
