                         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.
