The Thompson Creek mine has reduced its cut-off grade for moly to 0.03% from 0.04% assuming $10/lb moly and increased costs above $5/tonne. See http://www.kitco.com/pr/1738/article...

This would make Sisson's 109M tonne figure ore grade on just the moly alone!

This now makes the 214M tonne figure more in the realm of an economic body without any additional tonnage being defined.

Things keep on looking better.
