malamutus, I don't know the answer to your questions but it has always been an issue with me the spread in the value of our concessions. I mean $10,000-$30,000? Maybe if they said $20,000-$25,000 per acre that would sound logical. Why the big spread? I realize some areas may be more lithium-rich than others but wow, what a difference. Think I'll pull for the $30,000 per acre figure. IMO Junebug
