Mineral resource company Wealth Minerals has completed transient electromagnetic and gravity geophysical surveys at the Laguna Verde lithium project, in northern Chile, with its geophysical contractorreporting that the data quality is good to excellent for both surveys.
The resulting gravity model suggests a basin whose depth varies between 400 m and just over 1 000 m within the surveyed area. This is consistent with previously reported historical work completed by a third party, which concluded that the basin thickness was about 500 m.
Conductivity variations within this interpreted basin suggest the presence at depth of saline groundwater (potential brine) in lateral proximity to the surface body of water, at an interpreted depth of 200 m to 300 m, with the strongest response at the western end of the lake. A zone of low resistivity is also observed at depth to the north-east of the lake, representing perhaps a (partially) separated volume of saline groundwater.
Wealth Minerals says drill targeting has not yet been completed but initial results suggest up to three shallow drill targets in close proximity to Laguna Verde and an additional drill target to test the interpreted deeper brine to the north-east.
