If Xstrata is putting in $15mil and intend developing the area into a 'globally significant' copper area, MRX got to be worth more than its bottom line sp they are sitting on at the moment.
Technically the sp is performing well atm with starved sellers on the second day of selling/profit taking. Renewed interest could spike the sp.
ps. meerkat don’t bother replying as I value Xstrata judgement on this far greater than yours thanks.
