Mike says that upgrading the inferred to indicated would require a significant investment of time and money.

I'm not sure I believe that. The Tetra Tech Resource Estimate recommended drilling 2 holes to move some inferred to measured and indicated. Cost was $428K. If it turns out that these two drill holes would have made a significant difference to our waste rock, then I view that as a major failure of management. When the report is filed we will know some more info.
