Lithium
"Lithium: Based on the anomalous occurrences of lithium noted in the east arm of the Black Rock Desert and north of Gerlach on the playa (Nash 1996) it is believed that the South Playa Area has medium potential. Volcanic rocks and related sediments near calderas ring fractures and moat sediments are also of medium potential other volcanic rocks are considered low potential. These types of rocks occur in the Lahontan cutthroat trout Area Sliver (sic)."[1]
