We know that this is the highest point of leverage of any project and good thinking here costs relatively little compared to the massive value add. Ideas and approaches we have found useful in this area include:
Don’t be bound by JORC definitions, use your best guess of how the resource and grades will look when its drilled out .
Use spreadsheets and mine planning tools to easily explore options, after all it’s a financial ranking we want. Therefore make them simple and easy to use and avoid Black Box inputs ( inputs that cannot be easily and simply checked for gross errors)
Do this work in house rather a than through a large bureaucratic consultancy . You want to be able to quickly simply and cheaply explore avenues of value.
Important to document all cases so as you have a clear rationale and demonstration that you have covered most if not al the bases.
