u3o8:
Uranium Participation Corporation also has two series of warrants that trade on the TSX, symbols U.WT (expires May 10, 2007, strike price $6.25) and U.TW.A (expires September 14, 2008, strike price $12). With the May '07 warrants, Americans can buy and sell them, but cannot convert them to stock; so, you need to sell them before they expire, and they are pretty illiquid. I assume that the September '08 warrants are the same, but don't know for sure.
A leveraged way to play the metal.
