Acsienment Module 4 Ooention 4 4. FGO cut-off grade (in g/t ) FGOcog:mr(PCs)Cp+Ca+Cr+Cmf+Com+Csibc+Cmc 4. Calculate the FGO cut-off grade (in g/t ) for the model you built for the precious metal mine in the assignment for Module 3. Use the completed Excel spreadsheet of the model on page 3 . Herewith additional information to use in this question: - Cmc= Rehabilitation (closure) cost - Cmf=R10.44/t treated - Csibc=R40/t treated - m=94% - Cr= Ore Transport Cost - Cs includes off mine, smelting \& refining, royalties, metal transport, marketing and corporate costs. Beware - Cs must be expressed in Rand per gram of metal produced. Tip: Ensure that you use the correct units as stated in the formula (R,$,0z,kg,g, etc. ) and conversion factors in this question in order to express the cut-off grade in g/t. (40%)
