Geologic Maps

From Reno, 16 miles south on U.S. Highway 395 to junction with dirt road that leads east, up the flank of Virginia Range, about 6 miles to Jumbo mining district.


The Jumbo district is a small lode mining district on the opposite flank of the Virginia Range from the Comstock district. Most of the mines are near the crest of the range (sees. 34 and 35, T. 16 N., R. 20 E.). Small amounts of placer gold were recovered from placers in this district.

Production History

Production history: Most of the placer gold credited to the Jumbo district was recovered between 1937 and 1940, by small-scale methods.


The placer gold in the Jumbo district was probably derived from the small oxidized veins that cut the Alta Formation (Miocene). Free gold is the only economically important metal in the veins.


Bonham, 1969: Describes lode deposits; notes small-scale placer mining.
