I.X.L. District


Other Names: Silver Hill, Silver Hills Range, Silver Range, Cox Canyon, Job Peak, Stillwater, Pike Hollow

County: Churchill

Discovered: 1860

Organized: 1879

Commodities: gold, silver, lead, copper, fluorspar


Located in the Stillwater (Silver Hill) Range. The district includes the Cox Canyon area on west slope of range, the Pike Hollow area on summit of range, and the I.X.L. Canyon area on east slope of range. The 1866 map shows the district covering the entire southern end of the Stillwater Range. The district is probably the Silver Range district mentioned by the U.S. Geological Survey (1920).

Cox Canyon is sometimes considered to be a separate district, and the Job Peak area, to the south on the east side of the range, is sometimes included in I.X.L., but is considered to be a separate district. All of the area is within the large Silver Hill district of DeGroot (1863).

Illipah District


County: White Pine

Discovered: 1986 (?)

Active: 1987-1989

Commodities: gold


he lllipah district is located in T19N, R58E and includes Antelope Mountain, north of Little Antelope Summit. The district contains one significant gold deposit.

Imlay District


Other Names: Humboldt, Humboldt House, Prince Royal, Eldorado, El Dorado, Lone Mountain

County: Pershing

Discovered: 1860

Organized: 1860

Commodities: gold, silver, mercury, tungsten, antimony, fluorspar, kaolin, sulfur, beryllium


Located on the north end of the Humboldt Range, the district includes Prince Royal Canyon (Prince Royal district) on the north, Humboldt Canyon (Humboldt district) in central area, and Eldorado Canyon (Eldorado district) on the south. The 1866 map shows the district to cover the eastern tip of the northern Humboldt Range and to extend across the valley to the East Range (topography was in error). The Lone Mountain district mentioned in the Territorial Enterprise (1863) may have been in this area.

Imlay Placer District Description


West flank of the north end of the Humboldt Range between Prince Royal and Eldorado Canyons, Tps. 31 and 32 N., Rs. 33 and 34 E.

Geologic Maps

From Lovelock, 37 miles north on Interstate 80 to Imlay. Numerous dirt roads lead from the highway east to the mining areas.


Placers occur in Imlay Canyon, Antelope Canyon, and probably in other canyons at the north end of the Humboldt Range. The placers in Imlay Canyon are near the Imlay mine (sees. 30 and 31, T. 32 N., R. 34 E.).

Production History

Substantial amounts of placer gold have been credited to the Imlay or Humboldt district between 1913 and 1951. For a few years between 1938 and 1949, however, placer gold actually recovered from gravels in Willow Creek (see 98, p. 83-84) was credited to the Imlay district. Placer-mining activity in the Imlay district was apparently restricted to small-scale drywashing of the gravels.

The Willow Creek placers are richer than the Imlay Canyon placers, and it is probable that a considerable part of the placer production credited to the Imlay district actually originated in the Willow Creek district. I have changed the district data for those years where exact production can be credited to the proper district, but I estimate that at least 500 ounces credited to the Imlay district was produced from Willow Creek placers.


The probable source of the placer gold in the Imlay district is gold-bearing veins that occur in Triassic sedimentary rocks in the region. The Imlay vein, the probable source of placer gold in Imlay Canyon, is composed of hard white quartz containing silver and gold.

Independence Mountains District


Other Names: Jerritt Canyon, Jerritt, Burns Basin, Big Springs, Gance Creek

County: Elko

Commodities: gold, silver, antimony, mercury, barite, titanium


The Independence Mountains district was defined by LaPointe and others (1991) to include all of the Independence Mountains north of Taylor Canyon and south of the Aura district, including the old Burns Basin antimony district and the gold-mining areas of Jerritt Canyon (Jerritt), Big Springs, and Gance Creek. The Wood Gulch Mine area at the north end of the Independence Mountains is included in the separate Aura district.
