Information leading to the delineation of this focus area

Basis for focus area Playas within the Cactus-Sarcobatus Flats HUC8 watersheds selected from the Nevada state geologic map (Stewart and Carlson, 1978) with a 5 km buffer to include surrounding alluvium.
Identified resources Identified resources of lithium.
Production None.
Status Active exploration.
Estimated resources Bonnie Claire (2021): Inferred resource of 3,407.3 million tonnes with a Li grade of 1,013 ppm; 3,451.5 million kg Li, 18,372.3 million kg LCE (Samari and others, 2021).
Geologic maps Workman and others (2002), scale 1:250,000.
Geophysical data Partly adequate (10%) aeromagnetic coverage. Inadequate aeroradiometric coverage.
Favorable rocks and structures Unconsolidated sediments in closed basins.
Deposits Bonnie Claire deposit (USMIN Site_ID: NV00148).
Evidence from mineral occurrences USMIN; Lane and others (2018); Samari and others (2021).
Geochemical evidence Industry data.
Geophysical evidence Unknown.
Evidence from other sources Unknown.
Comments Models for Li brines and clays both require a Li source, and the source will be Neogene volcanic and sedimentary rocks within a HUC or within a neighboring HUC. It would be fabulous if mapping could identify these lithologies and their location with respect to basins (in the center of a HUC).
Cover thickness and description Sediment and clay at the surface and at depth.

New data needs Geologic mapping, geophysics, geochemistry.
Geologic mapping and modeling needs Updated geologic mapping.
Geophysical survey and modeling needs High-resolution, Rank 1 aeromagnetic and aeroradiometric surveys. Any geophysics that can define basin depth, geometry, volume, cross-cutting structures would be helpful for calculating the volume of brine, where to drill in the basin, or whether basin fluids might flow into an adjacent basin.
Digital elevation data needs Lidar inadequate.
