Compare TOPO precsion in 3DBM to TOPOG in GSF 1.0000 TOPO (% below surface) 3DBM precision 0.1000 TOPOG ( avg elev ) from GSF precision 15.0000 Bench height 0.6667 Block % equivalent to TOPOG precsion

The precsion of TOPOG smaller than the precision of TOPO so TOPO can not accurately measure the block % with the same precision as TOPOG

The TOPOG value will be used to calculate block percent as of August 2008 and the TOPO in the 3DBM ignored. This could cause differences in resource calculations with other tools but the differences will not be significant.

The affect of missing or zero values should be carefully considered.

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 quick check for an estimate of the pit profit and size. The slope used is limited by the block sizes and since it is only in 2-D, the profit is over likely over estimated. However, if no profitable pit is computed, then the economics should be reviewed since neither LG or FC designs will be computed

Total Value for Series of Pushbacks = 3747510.

Total Tons for Series of Pushbacks = 642870.

This calculation assumes that each pushback is mined top down sequentially and all economic material is processed. This PV value is intended only for use in comparing various series of pushbacks.

Each line is the cumulative totals for for the first bench total that exceeds the required production for the period.

Note that if an Ore percent is used, the ore tons represent whole blocks which are profitable, not the actual Ore based upon the Ore percent
