|Location and accuracy||The location is the site of a mining camp set up near the mouth of Yankee Creek in 1932. Yankee Creek is a tributary of Porcupine Creek.|
Gold and cassiterite occur in placers near the mouth of the creek.The source of the gold and cassiterite is believed by miners to be the mineralized zone on Porcupine Dome (Burand, 1968, p. 29). Yankee Creek was mined intermittently through 1981 (Menzie and others, 1983, p. 53).
