Uranium Mine Flood That Sparked a 2006 Price Surge Returns (Ad)

This past May, flooding cut the supply route into the largest uranium complex on the planet, and in July Cigar Lake went down a second time. Gerardo Del Real calls this the Third Convergence Event and has backed three small companies positioned in front of it.tc pixel
