Raster map showing buffered distances around granitic rock units with Z-scores in the >2.5 class when attributed with Li grades from the Geological Survey of Western Australia’s geochemistry database (WACHEM). Buffer distances and their assigned relative prospectivity values are based on their correlation with exploration drillhole data. Red represents the highest prospectivity values and blue represents the lowest prospectivity values.
