WARM SPRINGS DISTRICT
The Warm Springs district is in northwest Humboldt County near Denio, Oreg. The first discoveries were in 1863, but production was hindered for some time by the hostile Bannock Indians, who burned a mill and drove out the miners (Vanderburg, 1938b, p. 49). The principal mine in the district is the Ashdown.
Production of the district is not known, but Vanderburg (1938b, p. 49) estimated that it was $400,000, mostly in gold from the Ashdown mine. From 1937 through 1957, a total of 5,178 ounces of lode gold and 10 ounces of placer gold was reported. Total gold production through 1959 was about 24,000 ounces.
The country rock is slate of undetermined age and is intruded by granite and porphyry. At the Ashdown mine the ore deposit is in a quartz vein in granite. Free gold occurs in a gangue of quartz.
WINNEMUCCA DISTRICT
The first discovery in this district, which is 4 miles northwest of the town of Winnemucca, was made in 1863 by an Indian named Winnemucca (Vanderburg, 1938a, p. 51-54). The most important mine in the early days was the Pride of the Mountain, which produced an estimated $1 million in precious metals (Ferguson and others, 1951). In the early 1900's, high-grade gold ore discoveries near Barrett Springs created a short-lived rush; from 1937 through 1943 there was a renewal of activity, mainly at the Pansy Lee mine.
Production data are incomplete for the early years. During 1910-35, a total of $132,433 in gold and silver was produced (Vanderburg, 1938a, p. 51), and during 1935-59, about 10,070 ounces of gold was produced. Total gold production through 1959, including early production from the Pride of the Mountain mine, was probably 35,000 ounces.
The deposits on Winnemucca Mountain include veins and replacement deposits in hornfels and limestone of the Winnemucca Formation, of Late Triassic age. This formation locally is intruded by diorite (Ferguson and others, 1951). In the Barrett Springs area, the deposits are gold and silver-rich quartz stringers and veins in the slates of the Raspberry Formation of Late Triassic age (Ferguson and others, 1951).
