Location and accuracy For this record, the site of the Florida Creek placer mine is at a cabin on upper Florida Creek, in the southeast quarter of section 19, T. 7 N., R. 12 W., of the Fairbanks Meridian. The location is accurate within a half mile. The site corresponds to location 47 in Cobb (1972), and roughly to the site for Florida Creek, U.S. Bureau of Land Management MAS number 0020480076.

Geologic setting

Geologic description

Bedrock along Florida Creek consists predominantly of diabase (Hess, 1908). The general area is underlain by Paleozoic or Proterozoic siltstone and sandstone, which is in fault contact with Triassic gabbro (Reifenstuhl and others, 1997 [RI 97-15a]). These rocks in turn are overlain by Tertiary gravel terraces, such as the one on McDonald Bar (Chapman and others, 1982).
Placer gold production was reported around 1904 on Florida Creek (Prindle and Hess, 1905). The deposits proved to be very narrow, but as deep as 15 to 20 feet. Through 1904, less than 100 ounces had been mined, and production diminished after that (Hess, 1908). Mining was reported in 1939 and 1940. Frank Dinan drift mined in 1951 on his claims on Florida Creek (Williams, 1951).

Production and reserves

Workings or exploration The earliest date of placer mining on Florida Creek is unknown. However, less than 100 ounces of gold had been mined by 1904, and no records have been published of subsequent production. Mining activity was reported in 1939 and 1940 (Smith, 1941; Smith, 1942). Frank Dinan drift-mined in 1951 on his claims on Florida Creek (Williams, 1951).
Indication of production Yes; small
Production notes Less than 100 ounces of gold had been mined by 1904. No records have been published of subsequent production. Cobb (1977) speculated that total production probably was no more than 200-300 ounces of gold.
