able).  The results of the study may reasonably serve as the basis for a final decision by a proponent or financial institution to proceed with, or finance, the development of the project.  The confidence level of the study will be higher than that of a pre-feasibility study.                   |
| indicated mineral resource | That part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit.  Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing and is sufficient to assume geological and grade or quality continuity between points of observation.  An indicated mineral resource has a lower level of confidence than that applying to a measured mineral resource and may only be converted to a probable mineral reserve. |
| inferred mineral resource  | That part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling.  Geological evidence is sufficient to imply but not verify geological and grade or quality continuity.  An inferred mineral resource has a lower level of confidence than that applying to an indicated mineral resource and must not be converted to a mineral reserve.  It is reasonably expected that the majority of inferred mineral resources could be upgraded to indicated mineral resources with continued exploration.                                                                                                                          |

| measured mineral resource | That part of a mineral resource for which quantity, grade or quality, densities, shape, and physical characteristics are estimated with confidence sufficient to allow the application of modifying factors to support detailed mine planning and final evaluation of the economic viability of the deposit.  Geological evidence is derived from detailed and reliable exploration, sampling and testing and is sufficient to confirm geological and grade or quality continuity between points of observation.  A measured mineral resource has a higher level of confidence than that applying to either an indicated mineral resource or an inferred mineral resource.  It may be converted to a proven mineral reserve or to a probable mineral reserve.                                                                                                                                                                           |
| mineral reserve           | The economically mineable part of a measured and/or indicated mineral resource.  It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at pre-feasibility or feasibility level as appropriate that include application of modifying factors.  Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified.  The reference point at which mineral reserves are defined, usually the point
