Location and accuracy This alluvial placer gold mine is on Lindblom Creek, an east tributary to Snake River. The placer is upstream of the Snake River road crossing of Lindblom Creek and 1.5 miles south-southwest of Mount Byrnteson. This is locality 97 of Cobb (1972 [MF 463], 1978 [OFR 78-93]). The location is in the east-central part of section 15, T. 10 S., R. 34 W., Kateel River Meridian, and is accurate to about 500 feet.

Geologic setting

Geologic description

Small amounts of placer gold and scheelite are present on Lindblom Creek. Some placer gold was produced from 4- to 5-foot-thick gravels in the narrow, 25-foot-wide part of the upper creek (Collier and others, 1908; Moffit, 1913). Some scheelite-bearing quartz veins are also reported in the drainage (Coats, 1944; Anderson, 1947; Thorne and others, 1948).
Lower Lindblom Creek drains an area of sulfidized schist marked by an arsenic soil anomaly defined as greater than 400 ppm arsenic. A gold-in-soil anomaly, contained within the arsenic anomaly, defined as greater than 80 ppb gold, extends for about 2000 feet along and immediately north of Lindblom Creek (BHP Minerals, written communication, 1990; C. C. Hawley, written communication for Kennecott Exploration Company, 1993). The arsenic anomaly projects toward the extensive arsenic anomaly at the Rock Creek deposit (NM207) but is separated from it by a possibly barren zone along the post-mineral Brynteson fault, the unnamed, north-striking fault mapped by Hummel (1962 [MF 247]), about one-half mile west of Mount Brynteson.
The country rocks are mainly chloritic mica schist of Paleozoic protolith age (Hummel, 1962 [MF 247]; Sainsbury, Hummel, and Hudson, 1972 [OFR 72-326]; Till and Dumoulin, 1994; Bundtzen and others, 1994).
