Silver is found generally in lead ores, copper ores, and cobalt arsenide ores and is also frequently associated with gold in nature. Most silver is derived as a by-product from ores that are mined and processed to obtain these other metals. Deposits of native chemically free, or uncombined silver are also commercially important.

Because gold is washed down into placers over time, areas where a lot of gold has been found by earlier miners will - even if the placer was played out - very likely have gold again. Donlt believe the 49 ers got it all far from it. Advance sin technology and recent gold depostis continue to allow productive searches for gold bearing material.
