12 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

23 D.G. MacIntyre & Associates Ltd. Conclusions Glacier Gulch deposit is a moderate size, relatively high grade porphyry Mo-W deposit Glacier Gulch deposit is a moderate size, relatively high grade porphyry Mo-W deposit the deposit does not come to the surface and will have to be mined by underground methods the deposit does not come to the surface and will have to be mined by underground methods current Mo commodity prices have renewed interest in porphyry Mo deposits current Mo commodity prices have renewed interest in porphyry Mo deposits a detailed feasibility analysis is required to determine if Glacier Gulch has the potential to be an economically viable mine a detailed feasibility analysis is required to determine if Glacier Gulch has the potential to be an economically viable mine
