Common use of Ore Samples Clause in Contracts

Ore Samples. The mineral content of all ore mined and removed from the Claims (but excluding ore leached in place) and the quantities of constituents recovered by Payor shall be determined by Payor, or with respect to such ore which is sold, by the mill or smelter to which the ore is sold, in accordance with standard sampling and analysis procedures, and shall be weighted average based on the total amount of ore from the Claims crushed and sampled, or the constituents recovered, during an entire calendar quarter. Upon reasonable advance written notice to Payor, Payee shall have the right to have representatives present at the time samples are taken for the purpose of confirming that the sampling and analysis procedure is standard and acceptable according to accepted industry practices. 8. Commingling of Ores. Payor shall have the right to mix or commingle, either underground, at the surface, or at processing plants or other treatment facilities, any material containing Valuable Minerals mined or extracted from the Claims with ores or material derived from other lands or properties owned, leased or controlled by Payor; provided, however, that before commingling, Payor shall calculate from representative samples the average grade of the ore from the Claims and shall either weigh or volumetrically calculate the number of tons of ore from the Claims to be commingled. As products are produced from the commingled ores, Payor shall calculate from representative samples the average percentage recovery of products produced from the commingled ores during each month. In obtaining representative samples, calculating the average grade of commingled ores and average percentage of recovery, Payor may use any procedures acceptable in the mining and metallurgical industry which Payor believes to be accurate and cost-effective for the type of mining and processing activity being conducted, and Payor's choice of such procedures shall be final and binding upon Payee. In addition, comparable procedures may be used by Payor to apportion among the commingled ores any penalty charges imposed by the smelter or refiner on commingled ores or concentrates. The records relating to commingled ores shall be available for inspection by Payee, at Payee's sole expense, at all reasonable times, and shall be retained by Payor for a period of two (2) years. 9.
