stockwatch.com Neil Foran's Margaret Lake Diamonds Inc. (DIA) rose 1.5 cents to 21.5 cents on 97,000 shares. The close might seem impressive if you have been away from the market for a few weeks, but the company completed a 1:10 rollback in mid-November that compacted nearly 60 million shares into a tidy six-million-share black hole. A new big-bang expansion is now under way, as Mr. Foran, president and CEO, is offering up to 5.5 million shares at 13.5 cents apiece -- and each of those shares will come with a warrant exercisable at 18 cents.
