BAJ has far more upside folks.BAJ has a massive property, high grades, low cash costs, and they are currently in the construction phase of a mining facility that will be completed in 2013. STRONG BUY ratings from Analysts across the board. If there is one junior copper player with the most upside going forward, it's without a doubt BAJ. Easy 5-7 bagger from current levels. Unlike CUU, BAJ is going to be producing copper. CUU will take 6-8 years before they mine the property.
