	 8.      	 EXERCISE OF OPTION 

	 
	 8.1      	 Once Cavalier has incurred the exploration
        expenditures, and made the payments set out in Section 3.1, Cavalier will,
        subject to the right of Gervais to receive the Royalty and the obligation
        of Cavalier to make the annual payments set out in Section 3.2, own an
        undivided 100% of Gervais' right, title, and interest in and to the Claims.
      

	 
	 9.      	 ROYALTY 

	 
	 9.1      	 Cavalier will pay to Gervais an annual

        each yearly quarter based upon a year commencing on the 1st day of January
        and expiring on the 31st day of December in any year in which production
        occurs. Within 60 days after the end of each year for which the Royalty
        is payable, the records relating to the calculation of Net Smelter Returns
        for such year will be audited by Cavalier and any adjustments in the payment
        of the Royalty will be made forthwith after completion of the audit. All
        payments of the Royalty for a year will be deemed final and in full satisfaction
        of all obligations of Cavalier in respect thereof if such payments or
        calculations thereof are not disputed by Gervais within 60 days after
        receipt by Gervais of the said audit statement. Cavalier will maintain
        accurate records relevant to the determination of Net Smelter Returns
        and Gervais, or its authorized agent, shall be permitted the right to
        examine such records at all reasonable times. 












 - 5 - 

	 9.3 	 The determination
        of Net Smelter Returns royalty hereunder is based on the premise that
        production will be developed solely on the Claims except that Cavalier
        will have the right to commingle ore mined from the Claims with ore mined
        and produced from other properties provided Cavalier will adopt and employ
        reasonable practices and procedures for weighing, sampling and assaying,
        in order to determine the amounts of products derived from, or attributable
        to commingled ore mined and produced from the Claims. Cavalier will maintain
        accurate records of the results of such sampling, weighing and analysis
        with respect to any commingled ore mined and produced from the Claims.
        Gervais or its authorized agents will be permitted the right to examine
        at all reasonable times such records pertaining to comingling of ore or
        to the calculation of Net Smelter Returns.

	  	 	 
	 9.4 	 Cavalier shall
        have the right at any time to purchase one-half of the Royalty by paying
        to Gervais the sum of $1,000,000 per Royalty percentage point.

        data compiled by Cavalier with respect to the Claims;

	 	(c)  
	 have the right, and obligation
        on demand made by Gervais, to remove from the Claims within six (6) months
        of the effective date of termination all facilities erected, installed

        that at the option of Gervais, any or all of facilities not so removed
        will become the property of Gervais; and 

	 	(d)

        interest in and to the Claims in favour of Cavalier which Cavalier will
        be entitled to register against title to the Claims provided that transfer
        of legal title to the Claims as set forth in this Subsection 11.1 is for
        administrative convenience only and beneficial ownership of an undivided
        100% interest in the Claims will pass to Cavalier only in accordance with

        successors and permitted assigns. 

	 
	 22.      	 TERMS 

	 
	 22.1      	 The terms and provisions of this Agreement shall
        be interpreted in accordance with the laws of British Columbia. 

	 
	 23.      	 FORCE MAJEURE 

	 
	 23.1      	 No party will be liable for its failure to perform
        any of its obligations under this Agreement due to a cause beyond its
        control (except those caused by its own lack of funds) including, but
        not limited to acts of God, fire, flood, explosion, strikes, lockouts
        or other industrial disturbances, laws, rules and regulations or orders
        of any duly constituted governmental authority or non- availability of
        materials or transportation (each an "Intervening Event"). 

	 
	 23.2      	 All time limits imposed by this Agreement, other
        than those imposed by Section 5, will be extended by a period equivalent
        to the period of delay resulting from an Intervening Event described in
        Subsection 23.1. 

	 
	 23.3      	 A party relying on the provisions of Subsection
        23.1 will take all reasonable steps to eliminate an Intervening Event
        and, if possible, will perform its obligations under this Agreement as
        far as practical, but nothing herein will require such party to settle
        or adjust any labour dispute or to question or to test the validity of
        any law, rule, regulation or order of any duly constituted governmental
        authority or to complete its obligations under this Agreement if an Intervening
        Event renders completion impossible. 

	 
	 24.      	 ENTIRE AGREEMENT 

	 
	 24.1      	 This Agreement constitutes the entire agreement
        between the parties and replaces and supersedes all prior agreements,
        memoranda, correspondence, communications, negotiations and representations,
        whether verbal or written, express or implied, statutory or otherwise
        between the parties with respect to the subject matter herein. 

	 
	 25.      	 TIME OF ESSENCE 

	 
	 25.1      	 Time will be of the essence in this Agreement. 

	 
	 26.      	 ENFORCEMENT OF AGREEMENT 

	 
	 26.1      	 The covenants, promises, terms and conditions contained
        herein will be binding upon the parties jointly and severally and may
        be enforced by each as against each other inter se. 



 IN WITNESS WHEREOF the parties hereto have executed
  this Agreement as of the day and year first above written.
