He is on paper but he's not responded to the teams emails in months and months. As I said, the only people left (and running this company now) are the engineers, with little money. Yifu ran off to to work with the government about anonymity and took the millions with him.

Being MIA is almost as bad as being active. Being an owner, he could show up and any time and really mess things up. As long as he is still associated with this project in any way (and he is by still being an owner), I strongly recommend avoiding them at all costs. There are other, respectable, mining companies out there.
