1.           For the purposes of this Agreement, the term "Net Smelter Returns" shall mean the net proceeds actually paid to the Optionee from the sale by the Optionee of minerals mined and removed from the Property, after deduction of the following:

(a) smelting costs, treatment charges and penalties including, but not being limited to, metal losses, penalties for impurities and charges for refining, selling and handling by the smelter, refinery or other purchaser; provided, however, in the case of leaching operations or other solution mining or beneficiation techniques, where the metal being treated is precipitated or otherwise directly derived from such xxxxx solution, all processing and recovery costs incurred by the Optionee, beyond the point at which the metal being treated is in solution, shall be considered as treatment charges;

(b) costs of handling, transporting and insuring ores, minerals and other materials or concentrates from the Property or from a concentrator, whether situated on or off the Property, to a smelter, refinery or other place of treatment; and

(c)           ad valorem taxes and taxes based upon production, but not income taxes.

2.           In the event the Optionee commingles minerals from the Property with minerals from other properties, the Optionee shall establish procedures, in accordance with sound mining and metallurgical techniques, for determining the proportional amount of the total recoverable metal content in the commingled minerals attributable to the input from each of the properties by calculating the same on a metallurgical basis, in accordance with sampling schedules and mining efficiency experience, so that production royalties applicable to minerals produced from the Property may reasonably be determined.
