Ann: DEANCORP BECOMES SUBSTANTIAL SHAREHOLDER , page-5

Interesting that they mention his involvement with ZYL. Mal bought shares in ZYL, then loaned them money secured over their IP. He rolled the existing Board and then pulled support for ongoing fund-raising, resulting in administration. As a result of his debt/equity investments, he ended up with the ZYL IP, while other shareholders ended up with one tenth of the shares in a new mining entity.

I don't have a strong opinion on his actions, but some ZYL shareholders had some at the time, so it may be worth being aware of that story.

Maybe worth casting an eye back over some old ZYL threads.
