![]() In most of the very productive lode mining districts, only small amounts of placer gold have been recovered, whereas in the very productive placer districts, lode-gold production is close to, and sometimes less than, placer gold production. In the few districts for which the source of the gold is unknown, it is presumed to be small scattered veins in the adjacent bedrock. Most of the placer gold found in Nevada has been derived from veins and replacement deposits that have been successfully worked for the gold and silver content of the ores. Annotated references to all reports give information about individual deposits for each district. The location, areal extent, past production, mining history, and probable lode source for each district are summarized on the basis of information obtained from a wide variety of published reports relating to placer deposits. One hundred and fifteen placer districts in Nevada are estimated to have produced a minimum of 1,700,000 ounces of placer gold from 1849 to 1968.
