Might need some definitions to understand the graphs. I can't explain why the amount of gold goes zooming off to over 3g/t in the 7th year. Are they expecting to find nuggets at the bottom of the pit?
grade
The amount of metal in each ton of ore, expressed as troy ounces per ton or grams per tonne for precious metals and as a percentage for most other metals.
Cut-offgrade : the minimum metal grade at which an orebody can be economically mined (used in the calculation of ore reserves).
Mill-head grade : metal content of mined ore going into a mill for processing.
Recovered grade : actual metal content of ore determined after processing.
Reserve grade : estimated metal content of an orebody, based on reserve calculations.
