Access
From Kingman, 3 miles south on U.S. Highway 66 to Lewis placer area; 6 miles southeast from Kingman on dirt roads to Lookout placer area.
Extent
Three minor placer deposits occur in gravels in the low hills near Kingman. The Lewis placer and the Boulder Creek placer are in the McConnico mining district southwest of Kingman; the Lookout placer is in the Maynard mining district southeast of Kingman.
The Lewis placer is on the property of the Bi-Metal gold mine (sec. 4, T. 20 N., R. 17 W.). The placer gold is found in some small gullies within, or at the border of, the mineralized granite on Kingman Mesa. Some nuggets worth 50 cents were recovered from the area.
The Boulder Creek placer is near the Boulder Creek group of lode claims (approximately sec. 10, T. 20 N., R. 17 W.); the gold veins were located in 1906 after tracing detrital gold to the outcrops.
The Lookout placer is at the north end of the Hualapai Moun tains (Tps. 20 and 21 N., R. 16 W.). The placers are found in areas of shallow gulch and hillside gravels, but the exact location is uncertain.
Production History
Most of the placer gold known to have been recovered from the Kingman area placers was recovered from the Lewis placer between 1932 and 1933. A. E. Lewis reportedly recovered $6 to $10 per day at the Bi-Metal property using two sluices. Wilson (1961, p. 34) states that $150 in placer gold was recovered from the Lookout placer during the 1932-33 season, but this recovery was apparently not reported to the U.S. Bureau of Mines.
Source
The Lewis placer resulted from the erosion of free gold concentrated in cavities created by the oxidation of pyrite in the ranite at the Bi-Metal property. The Boulder Creek placer resulted from the erosion of parts of the Boulder Creek group of veins. The origin of the Lookout placer is unknown.
