Underground Face Weighted Average Grade Guide

This video explains a handy little tool for estimating or working out development grades on the go underground. It can be printed out and used for estimating while underground or on the digital version, you can actually change the vein grades and ore percentages to get a more accurate reading of what the face will go. I have used made up cut off grades for waste, low grade or ore, but you can simply update these in the sheet (speak to your engineers), and the colours will colour themselves in the chart accordingly.

If you would like anymore information or a copy of the grade guide, simply contact us.
