Box 48600 (617) 854-4000 Vancouver, B.C., Canada V7X 1T2 (604) 687-5744 DEREGISTRATION OF COMMON SHARES The Registrant, by this Post-Effective Amendment No. 2, hereby amends its Registration Statement on Form S-8 (No. 33-9539), filed by the Registrant's predecessor Granges Inc. with the Securities and Exchange Commission (the "Commission") on October 16, 1986, as amended by Post-Effective Amendment No. 1 thereto, filed with the Commission on November 30, 1990 (collectively, the "Granges Registration Statement"), solely to remove from registration the remaining common shares, without par value (the "Shares") of the Registrant which remain unsold under such Granges Registration Statement. Effective upon the amalgamation of Granges Inc. and Da Capo Resources Ltd. on November 1, 1996, the Registrant, as the amalgamated entity, adopted, as successor in interest, the Stock Option Plan (the "Plan") of Granges Inc. The 4,500,000 common shares issuable under such Plan had been registered for issuance under the Granges Registration Statement. On June 19, 2002, the Registrant effected a one for 20 consolidation of its common shares. After giving effect to this share consolidation, the maximum number of shares issuable pursuant to the Plan decreased from 4,500,000 to 225,000 common shares. On May 2, 2003, the Plan was amended as approved by the shareholders of the Registrant to increase the maximum number of common shares issuable under the Plan from 225,000 to 1,000,000, which included the Shares registered but as yet unsold under the Granges Registration Statement. Concurrently herewith, the Registrant is filing a new registration statement on Form S-8 to register for issuance all of the 1,000,000 common shares issuable under the Plan. Accordingly, the remaining Shares that were registered and unsold under the Granges Registration Statement are being deregistered by this Post-Effective Amendment No. 2. Pursuant to Rule 478 promulgated under the Securities Act of 1933, as amended (the "Act"), and the undertaking contained in the Granges Registration Statement pursuant to Item 512(a)(3) of Regulation S-K promulgated under the Act, the Registrant hereby removes the Shares from registration. II-1 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements of filing on Form S-8 and has duly caused this Post-Effective Amendment No. 2 to Registration Statement on Form S-8 to be signed on its behalf by the undersigned, thereunto duly authorized in Littleton, Colorado, on May 22, 2003.
