The Rizzo Report increased the reserves At SIRG's

The Rizzo Report increased the reserves At SIRG's Chloride Copper mine and they are higher than previously estimated. The existing ore below the current bench levels from 3695 to 3420 values known between 3420 and 3310 could add another 13 Mlbs. Many holes were abandoned with higher than cut-off grade Cu values in and around the existing pit. Their continuation at depth could prove additional resources.  Based on the forgoing, it is safe to assume that the current known resources would provide a minimum of 50 Mlbs of ore; at 5Mlbs/annum, that would support a 10 year mine life.
