Jan 12, 2019· Nevada lead deposits are argentiferous silver/galena deposits. The superficial mined oxidized zones show the galena had altered to cerussite and anglesite, but deeper zones show the galena to be mixed with the silver, hence argentiferous galena. Lead ore mixed with silver and silver ore mixed with lead were mined in several Nevada districts.
