Commingling of Ore. 15.1 Lessee may commingle ore from the Leased Premises with ore from other properties, either before or after concentration or benificiation, so long as the data necessary to determine the weight and grade both of the ore removed from the Leased Premises and from the premises with which it is commingled, are obtained by Lessee. Lessee shall then use that weight and grade data to allocate Net Smelter Returns from the commingled ore between the Leased Premises and the other properties from which the commingled ore was removed. All such weight, grade and allocation calculations by Lessee shall be done in a manner recognized by the mining industry as practical and sufficient at that time.
