You are right, you don;t need much for $50 per ounce but the market is not going to trade at $50 per ounce in its current condition for lower grades. Hope that changes in 2013. Here is your request:
4M Oz Indicated @ 0.71 g/t and 0.3g/t cut-off and 1.7M Oz inferred @ 0.62 g/t and 0.3g/t cut-off
Chop off 1 million ounces in each category and the resource is averageing about 1 g\t.
In my last post I assumed the lower cut-off to gain about 2 million ounces!
