Glacier Gulch (Yorke-Hardy) Resource Estimate (Giroux, 2005) 0.20% MoS2 cutoff - 82,980,000 tonnes grading 0.295% MoS2 = 293,460,000 lbs Mo 0.30% MoS2 cutoff – 25,450,000 tonnes grading 0.424% MoS2 = 129,360,000 lbs Mo -minimum grade required for economic extraction -any rock grading less than cut-off not included in resource calculation = waste rock -reflects value of rock for commodity or commodities of interest -strongly influenced by mining cost e.g. higher cut-off for underground mine versus open pit -final cut-off grade can’t be determined until a detailed economic feasibility analysis is completed
