An Update on the Hydrogeology of Clayton Valley, Nevada.

This paper seeks to update and expand upon a previously published paper on the hydrogeology of the Clayton Valley lithium mining operation in Esmeralda County, Nevada. Water Rights are a critical and necessary component of the mine in order to pump lithium rich brine from the subsurface into solar evaporation ponds. Brine is passed through the pond system as grade increases before processing strong brine into lithium carbonate. The primary ash aquifer (Main Ash Aquifer) of the Clayton Valley has been the principal source for lithium bearing brine since 1966. Its history is now better understood with geochemical correlation performed on a sample taken from a well during construction in order to determine if it is from the same eruptive event as the Long Valley Caldera/Bishop Tuff in Mono County, California.
