considering it is currently at a 10th of a penny
Actually isn't that currently 100th of a penny.
My take on penny stocks is that they're penny stocks for a reason, sure you get lucky once in a while, but your odds are better to put $100 and buy a couple shares of a well-traded stock, or put it into S&P funds, which you can actually get a couple through houses for $100. Your chances of being rich are lower, but there is more stability and in the long run more growth.
Not to ruffle any dreams, but in every finance and investing class i took in business school (and god there were too many of them) the return-to-risk factor of penny stocks was equated to being about half that of the lottery. So your odds of being successful at a great magnitude is two times better with a hundred lottery tickets. This is factoring both risk and return keep in mind (with those betas and other ugly equations for portfolio risk), many people buy a penny stock and it goes to two cents, but factoring in return magnitude, I'd just play the lottery.
But all that being said, someone has to win the lottery, and some penny stock has to make it big. I just wouldn't be overly anxious of it happening anytime soon, because if there have been that many TV shows and reports done on the Canadian diamond mines then if there was a high potential of true value the big houses would be all over it. That and my old classmates working at Goldman Sachs would be calling me trying to get me to invest in their diamond company funds. That and my broker used to be heavily involved in diamond/ore investments in the North, a Detroit man, so if he isn't pushing Canadian diamond mines on me, then I'm guessing it isn't great for LT growth.
Hope you win the "stock lottery", you can buy a lot of fish equipment if it does well over 40 years or so.
