A former small Pb-Zn mine in SW¼ sec 1, T19S, R40E, MDM, 3.0 miles N8°W of Darwin and 1460 feet N 60°W of the Lucky Jim Mine, at an elevation of 5610 feet. The property consisted of 8 claims. Owned by Alex Ruona (1938) and later by Mrs. Marie Wilson-Ruona (1958). MRDS database stated accuracy for this location is 10 meters. Description and position updated (N36.31107 W117.59900) by Richard Muster based on observations in 2007.
Mineralization is a vein deposit hosted in thinly bedded bluish-gray limestone and calc-hornfels (tactite). The ore is galena with lead carbonate. The fissure strikes NW and is 2 to 4 feet wide. The mine has both Pb-Ag and W minerals, but was worked for Pb and Zn only. Local rocks include Carboniferous marine rocks, unit 2 (SE California Carbonate Assemblage).
Workings include surface and underground openings comprised of a shaft about 150 feet deep, several shallow shafts and open cuts.
NOTE: The USGS MRDS database provides 2 files for the Fairbanks mine. The coordinates presented in MRDS file #10033975 are N 36.29997 W 117.60951. There one can see some traces of mining activities, but it is not the Fairbanks mine proper. All references state that the Fairbanks mine is NW of the Lucky Jim mine and not SW.
