So the liquid traces of lithium suggest there is hard rock sources of lithium. There are three sources of lithium. Lithium brine, from salars in the South America aka the lithium triangle eg ORE. Lithium Challaice/callice i alwasy forget this one, which looks like rock but is concentrated salts found predominately in south america look up SQM largest producer of lithium in the world. Then hard rock lithium which is what TAW is doing at the moment. What they are suggesting is there is hard rock lithium in their concessions, due to the traces found in the water.
