Nevada Energy Metals (TSXV:BFF) (OTCQB:SSLMF) announced that it has acquired by staking the Humboldt Salt Marsh playa located in Dixie Valley, Churchill County, Nevada. The property consists of 911 claims covering 73.6 square km/28.4 square miles (7,363 hectares/18,194 acres) of salt marsh playa staked at a cost of approximately CDN $370,000.
As quoted in the press release:
Of the seven characteristics favorable for the formation of a Lithium brine deposit as outlined in the USGS deposit model, all seven are found in Dixie Valley. The Lithium deposit model for Dixie Valley is a Clayton Valley style brine deposit.
Dixie Valley Overview
Dixie Valley is located in west central Nevada, about 160 km east northeast of Reno. The entire basin is about 98 km long and up to 16 km wide. Humboldt Salt Marsh occupies the central part of the playa and is about 10 km north-south and 6 km east-west.
Dixie Valley is home to a large and long-lived geothermal system that is still active. The Caithness Dixie Valley geothermal power plant is producing about 64 megawatts of electricity making it the largest geothermal power plant in Nevada. The active geothermal system extends about 30 km roughly north – south along the entire west side of the valley. The heat source appears to be simple very deep circulation into the crust and is not related to igneous activity.
The conceptual deposit model is as the basin went through multiple wet and dry periods, Lithium dissolved by deep circulating geothermal fluids or leached from local rock units by surface and near surface water, seeped into the basin where it was concentrated by evaporation. Heavier brines sink into the deeper levels of the basin or flow downward along tilted permeable beds, potentially forming subsurface pools of Lithium rich fluids. The process can be likened to an inverted oil field, with the target material being descending fluids caught in gravity traps instead of ascending fluids caught in the tops of structures. This model is somewhat akin to placer gold deposits wherein large areas of very low grade sources are concentrated into economic grades.
