You have no idea how large a share it is or how large a mine it is. You simply discredit yourself and your arguments by assuming things without evidence. The description of the mine I'm aware of comes from Erol Musk where he says he traded a used plane that he had bought for 50k for 120k plus a share of a mine. Musk describes the mine as "a deposit in the middle of nowhere rather than a modern mine" [1].
So, he has an unknown share of a mine of dubious value. "Trust me, that isn't cheap." I think you've done a very good job of explaining why people shouldn't trust you, because, unbothered by a lack of knowledge you are happy to leap to conclusions.
