Location and accuracy McKinley Creek is a long, southeast-flowing tributary to the John River. The mouth of McKinley Creek is about 2 miles north of the junction of the Allen and John Rivers. The location and extent of placer prospects on McKinley Creek are unknown; the site is arbitrarily located at an elevation of about 1,500 feet on McKinley Creek, i.e. about in the center of this long creek.

Geologic setting

Geologic description

Schrader (1900) reported a pay streak of considerable width on McKinley Creek. Cobb (1976 [OF76-340]) in summarizing Schrader's report on the McKinley Creek occurrence, indicated that Schrader's location was uncertain and that it might instead be a description of Midas Creek or Crevice Creek. Cobb, however, provides no evidence to support his suggestion. Kurtak and others (1999) collected 3 panned-concentrate samples from McKinley Creek in the vicinity of this site. One of these samples contained 2 particles of coarse gold, with abundant magnetite and pyrite. The concentrate contains 625 ppb gold. The other 2 samples contained only moderate to minor amounts of magnetite and sulfides. Kurtak and others (1999) did not find any evidence of mining on McKinley Creek.

Production and reserves

Workings or exploration Schrader (1900) noted that 50 men were mining in the area in 1900. This, however, may have referred to creeks other than McKinley Creek, as Kurtak and others (1999) found no evidence of mining.
Indication of production None
Production notes Questionable prospecting and mining.
