    Net value/ ton Cutoff = 0.0000

    The net value per ton cutoff is applied to the value

    of the block ( excluding mining costs ) for each process and if the material is below cutoff it is redirected to a waste destination.

    If a net value per block is computed by the user via a user subroutine, Grail, or M612rp and stored in the 3DBM it can read and used by MSOPIT. However it is reccomended that a value/ton be computed and used by MSOPIT to compute value since cutoff grades can be applied and results summarized by material and destination.

    NOTE: The 2-D lg Analysis is done as a quickcheck for an estimate of the pit profit and size.The slope used is limited by the block sizes andsince it is only in 2-D, the profit is over likelyover estimated. However, if no profitable pit iscomputed, then the economics should be reviewedsince neither LG or FC designs will be computed
