I saw that - good job. You may want to post this:

The Rizzo Report increased the reserves 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.

This report was done by an international mining consulting company and proves that SIRG is a real company with real ore reserves.
