After giviing Hal all those   MEDIOCRE news releases and maps Hal was able to report that there could be a minimum of 90 million  metric tons and maximum of 200 million.metric based on the reported holes which have  a  weighted average grade of 1.8 lbs Lithium  per metric ton over a average   zone zone width of 60 meters.

Hal estimates there is a high probability that the tonnage could be refined and have a much higher grade but lower tonnage if it was given SPMT's database.
