Lithium Brine Projects


Location and Ownership

Radius Gold Inc. has recently applied for mineral concessions totaling 37,000ha covering four lithium brine targets in northern Mexico. On September 09, 2016, Advantage Lithium Corp announced it had signed a Letter of Intent (LOI) for an option agreement to earn up to a 70% interest in these four properties by funding exploration.


Northern Mexico presents an excellent opportunity for the discovery of new Li brine deposits. The geological environment shares key first-order characteristics with USGS Li brine models derived from producing Li brine deposits (including the Clayton Valley project, Nevada) and Mexico's mining friendly jurisdiction, excellent infrastructure and road accessibility, allow for potential low cost exploration.

Radius' exploration team recognized the potential of the large salar basins and compiled a database from historic lithium exploration conducted by the Mexican geological survey between 1987 and 1993. The work included a 1982 drill hole at La Union which returned a brine sample of 283 ppm Li.

A controlled surface sampling program has been completed which resulted in numerous anomalous lithium results including 189ppm Li at La Viesca, which attracted the attention of Advantage Lithium.

The four projects covering 37,000 hectares are located in the states of Chihuahua (La Union, La Union 2 and Santa Maria) and Coahuila (La Viesca).

Concession Details
State Project Approx. Property Size (ha)
Chihuahua La Union 10,000
  La Union 2 7,000
  Santa Maria 10,000
Cohuila La Viesca 10,000

All four projects are located in large, salar closed basins, in geological settings synonymous with USGS Li brine models. These shared characteristics include:
  1. Located in a desert climate with historic evaporate ponds;
  2. Large closed basin salar targets;
  3. Geothermal hotsprings observed at La Union and Viesca salars;
  4. Suitable lithium source-rocks;
  5. Subsurface highly saline aquifers described in historic data.
Advantage lithium plans to conduct further sampling to advance these projects, as well as, continued district scale exploration. Radius and Advantage Lithium recognize the underexplored nature of the region and have high hopes for the potential of discovery. Advantage Lithium will be the operator of the projects during the option period.
