Location: Timber Creek is a large, south-lowing stream which joins the John River west of Ninemile Hills. The locations of placer occurrences on Timber Creek are not described in detail. The site is arbitrarily placed about three-quarters of a mile north of the mouth of the creek.
Geology: Although Reed (1938) did not visit Timber Creek, he noted local reports that the creek was auriferous. According to Reed (1938), in the early 1900's no claims were allowed on the creek by popular agreement and the creek was reserved for men who had not made enough money during the first half of the summer to get them through the winter. Reed related that the gold was recovered from the bars of the stream by rocking and that a man could recover $4 per day (gold at $35/ounce). There is no other record of mining on this creek.
Workings: About $4/day in gold could be recovered from the bars of the stream using a rocker (Reed, 1938).
Age: Quaternary.
