Cut-off grade estimation - QueensMineDesignWiki

CALCULATING THE CUT-OFF GRADEMINERAL CLASSIFICATIONADJUSTING THE CUT-OFF GRADEREFERENCESThe most simplistic way to determine cut-off grade is through the break-even and internal method. This method is easy to use and involves minimal background information. It is preferred as a first estimate, and is most effective in the early planning phases of a project. Although the limited number of parameters makes this method a good first step, it is not ideal to use this method in the long term, since it does not take production capacity or discount rates into consideration.The internal...

British Columbia Mineral Deposit Profiles

The USGS published the first comprehensive set of mineral deposit models and related grade and tonnage probability curves (Cox and Singer, 1986).
