Other Names: Mandalay
Located on the west side of Sawtooth Knob in Antelope Range. The district is on the Humboldt-Pershing county line, but most of the district is in Humboldt County. Schilling (1976) used Mandalay as an alternate name but Mandalay Springs is actually located to the west, in the Sulphur district.

Sawtooth Placer District Description
Northwest end of the Antelope Range, Tps. 34 and 35 N., Rs. 30 and 31 E. (unsurveyed).

From Lovelock, 37 miles north on Interstate 80 to Imlay; from there, a light-duty road leads 28 miles northwest to Sawtooth Knob and placer area at the Humboldt County-Pershing County border.
The placer deposits in the Sawtooth district are in a nearly level area of approximately 6 square miles near the west side of Sawtooth Knob, a small prominence at the northern end of the Antelope Range. The gold is found in gravels composed of angular pebbles and few boulders. The gravels rest on a false bedrock of clay at depths of 8 inches to 2 feet; the clay in the gravels is said to be considerable and must be dried before drywashing the gravels. The gold recovered was coarse and rough and said to be 880 fine.
The placers were discovered in 1931 and were worked continually, although largely on a small scale, until 1942 and intermit- tently since that time. Some of the placer miners reportedly recovered $35 per day for short periods of time, but most of the miners were not so successful. Because there is little water in the area available for placer mining, dry concentration methods are used to recover the gold. Various attempts at large-scale placer mining were not successful.
Most of the production (810 oz.) was attributed to Humboldt County, where the major area of placer concentration is located, only 131 ounces of the total production being attributed to Pershing County. Placer production credited to the Sulphur district (located 6 miles west of Sawtooth Knob and noted for sulfur deposits) is included here in the Sawtooth district.
