cut-off grade means the grade of mineralization, established by reference to economic factors, above which material is included in mineral deposit resource/reserve calculations and below which the material is considered waste. Cut‐off grade may be either an external cut‐off grade. An external cut-off refers to the grade of mineralization used to control the external or design limits of a pit or underground mine based on the expected economic parameters of the operation. An internal cut‐off grade refers to the minimum grade required for blocks of mineralization present within the confines of an open pit to be included in mineral deposit estimates.
cut-off grade means the grade below which mineralized material will be considered waste. “deposit” is an informal term for an accumulation of mineralized material.
