Speculators are gambling on any mining company that might produce.

Through the second week of August, without a single word appearing in the news media, the share price of Mindax jumped by 50%. No one took any notice because Mindax is a true "penny dreadful" mining stock, with a market value of just $4.7 million. The reason a few smart speculators pushed the company's share price from 10¢ to 15¢ over five trading days is that Mindax believes it may have found a way to snatch control of one of the world's biggest undeveloped uranium deposits.
