Segregation of Property

3.1

The determination of Net Smelter Returns hereunder is based on the premise that production will be developed solely on the Property. If other properties are incorporated in a single mining project and metals, ores or concentrates pertaining to each are not readily segregated on a practical or equitable basis, the allocation of actual proceeds received and deductions therefrom shall be negotiated between the parties, provided that if the parties fail to agree on the application of the above calculations in the determination of the allocation of proceeds received or deductions therefrom, the determination of such allocation shall be referred to arbitration by a single arbitrator under the Commercial Arbitration Act (British Columbia) and the arbitrator shall have reference first to this Agreement, and then, if necessary, to practices used in mining operations that are of a similar nature. The arbitrator shall be entitled to retain such independent mining consultants as he or she considers necessary. The decision of the arbitrator shall be final and binding on the parties, and his or her costs, including those of any independent mining consultant retained by the arbitrator, shall be shared equally by them.
