Dear Mr. Landau:

         In light of the currently depressed mining industry, we have agreed to
amend that certain Agreement between Wolfranium Resource Corporation and LRS
Capital Inc., dated May 6, 1999 concerning the tungsten property with respect to
the payments required under section 3.2. We hereby agree to replace the
referenced section of the current agreement with the following:

         To pay the following amounts on or before the expiration of five (5)
         Business Days after each of the dated indicated:

         $5,000.00          first anniversary date of this Agreement
         $5,000.00          second anniversary date of this Agreement
         $15,000.00         third anniversary date of this Agreement
         $15,000.00         fourth anniversary date of this Agreement
         $20,000.00         fifth anniversary date of this Agreement
         $20,000.00         sixth anniversary date of this Agreement

         No other changes will be made at this time and all other remaining
provisions of the current Agreement shall remain in full effect. This
restructuring of the payments will not decrease the total amounts payable but
will considerably lessen the amount of the first two yearly payments.

         Please indicate acceptance of this amendment by signing below and
returning by fax:

Agreed to and Accepted this 19th day of April 2000.

/s/ Robert Landau
