I was hoping to ask about the drilling and the 171M tonnes of inferred waste too but I missed the part about how to register a question.
171 M tonnes could be a significant (i.e. 15%) increase to the 940.8 Tonnes of Proven Probable and, conversely, a large proportion of the 1.89 Billion tonnes of waste rock for the entire project.
I'd like to know where the bulk of this tonnage is located in relation to the pit shell (rind of the shell, or above, below or adjacent) to the bulk of the proven & probable. I don't quite understand how this much mineralized rock which is within the pit shell was not drilled to a higher confidence level for inclusion to the FS.
From the NR and some of the comments on this forum relayed from management, I get the sense that the bulk of this inferred/waste is a single area in the NE corner of the block model we had in June 2012 when drilling got started. At any rate, the 10 drills needed to update the 171M tonnes seemed like a big missed opportunity to improve the economics. I can only think that the pit shell model arrived too late to identify this potential for the 2012 drilling programme.
Elmer mentioned that new maps would be posted on the cuu website soon.
