I asked a friend of mine who holds Tyhee stock, and was an Interinvest client, "How have those other companies done that Dr. Black recommended investing in".........Here's her answer, "All down as much as Tyhee but I would rate them still pretty good investments for penny stocks: Romarco, Cornerstone Capital, Wi2wi, Williams Creek Gold. Hans was involved with all of these, mostly Canadian stocks".... "The latter, WICEF, appears to be in pretty good shape. Hans also bought heavily in LSG and IAG, both of which are doing OK. As you can see, I'm pretty heavy in mineral stocks, so I've got plenty of reasons to hope the commodity sector comes back."
