Can someone please read these result. I dont understand lithium yet. could you please tell me if they are good or bad.
Cheers.


Further results are now available for the interval from 380 to 830 feet (115.8 to 253.0 meters). Lithium concentrations for the interval varied from 25.8 mg/l (or 137.3 mg/l Li2CO3 equivalent*) at 380 feet, gradually increasing to approximately 41.3 mg/l (or 219.8 mg/l Li2CO3 equivalent*) at 830 feet. *Conversion based dividing the molar mass of Lithium Carbonate (Li2CO3, 73.891 g/mol) by twice the molar mass of Lithium (6.941 g/mol) giving a conversion factor of 5.323.
