Josephus,
i had a nearly identical response ready but decided not to post it. it's just a constant back and forth with people who don't believe that the valuation we give it can be that high. but it IS that high. why should we settle for much less?
i'm not sure a single company can afford to pay what we belive it's worth. maybe a few companies could collaborate and put the money together, but who knows.
it's as you say, we should just plow ahead to mining it ourselves. we will derive enough of our graphene from the bulk sample to fund the entire project and more if we choose.
put a reasonable dividend program in place and watch the shareprice skyrocket after we begin selling just about any amount of graphene at all.
in other words, like you say, we shouldn't sell for less than the deposit is truly worth.
