After Closing, in the event that the Purchased Percentage is less than 30%, the
Purchaser
   16
                                     - 12 -


shall have the right to increase its undivided interest pursuant to the terms
of Article 9 hereto.

2.2               Transfer.  At Closing, on and subject to the terms and
conditions set out in this Agreement, the Vendor shall convey, transfer, assign
and sell and the Purchaser shall acquire, accept and purchase all the right,
title and interest of the Vendor in and to the Purchased Assets and the Vendor
shall deliver documentation necessary to register, file or record the
Purchaser's interest in the Purchased Assets, as provided in Section 7.2
hereto.

2.3               Payment.  At Closing, on and subject to the terms and
conditions set out in this Agreement, in consideration of the sale to the
Purchaser of the Purchased Assets, the Purchaser shall:

                  (a)       pay the Estimated Purchase Price, less the Deposit
                            and less the Financing Deposit, if any, to the
                            Vendor;

Purchaser shall pay to the Vendor the Estimated Purchase Price less the Deposit
and the Financing Deposit, if any, and the Estimated Development Costs, within
30 days of the Closing Date, or such other reasonable time mutually agreed to
by the Parties, the Parties shall determine the Purchase Price and the
Pre-Closing Development Costs.

                  In the event that either the Estimated Purchase Price or
Estimated Development Costs are more than the Purchase Price or Pre-Closing
Development Costs, the Vendor shall forthwith pay to the Purchaser the
difference, if any, between the Estimated Purchase Price and the Purchase Price
and the difference, if any, between the Estimated Development Costs and the
Pre- Closing Development Costs.

                  In the event that either the Estimated Purchase Price or the
Estimated Development Costs are less than the Purchase Price or Pre-Closing
Development Costs, the Purchaser shall forthwith pay to the Vendor the
difference, if any, between the Estimated Purchase Price and the Purchase Price
and the difference, if any, between the Estimated Development Costs and the
Development Costs provided, however, that the Purchase Price shall in no event
be greater than the Maximum Purchase Price.

2.5               Arbitration.  If there is a dispute between the Vendor and
the Purchaser as to the appropriate adjustment to be made pursuant to Section
2.4 hereof, then the matter shall be submitted to arbitration by a single
arbitrator, if the Parties agree upon one arbitrator, or otherwise by three
arbitrators, of whom one shall be appointed by each of the Vendor and the
Purchaser and the third shall be chosen by the first two named before the
arbitration.  Unless the Vendor and the Purchaser agree otherwise, the
arbitrator or arbitrators, as the case may be, shall each be an independent
Chartered Accountant from a firm of at least 100 Chartered Accountants.  The
arbitration and the appointment of the arbitrator shall, unless expressly
provided for herein, be conducted in accordance with the Arbitrations Act
(Ontario).  The determination of such arbitrator, arbitrators or any two of
such three arbitrators, which shall be made within 30 days of the date upon
which the dispute was referred to him or them, shall be binding upon the Vendor
and the Purchaser and their respective successors and permitted assigns.  The
Vendor and the Purchaser shall co-operate in completing any arbitration as
expeditiously as possible and the arbitrator or arbitrators may engage such
experts to assist him or them as may appear to him or them appropriate.  Each
of the Vendor and Purchaser shall bear its costs and expenses incurred in
connection with the arbitration and other costs and expenses incurred in
connection with the arbitration shall be borne equally by the Vendor and
Purchaser.

2.6               Deposits.  In the event that the Purchaser fails to proceed
with the purchase of the Grouse Creek Assets contemplated hereby other than as
a result of a material misrepresentation of the condition of the Grouse Creek
Project by the Vendor, the Vendor shall be entitled to retain the Deposit and
the Financing Deposit, if any, as an estimate of liquidated damages to the
Vendor which the Purchaser stipulates is not a penalty.  In the
   18
                                     - 14 -


event the Purchaser proceeds with the Closing, the Deposit and Financing
Deposit, if any, shall be applied against the Purchaser's payment obligations
specified above.

2.7               Taxes.  The Purchaser shall be liable for and shall pay all
land transfer taxes and sales and related taxes, duties or like charges
properly payable whether under United States or Canadian federal, state,
provincial, municipal or local laws upon or in connection with the sale,
transfer or conveyance of the Purchased Assets excluding, for greater
certainty, income taxes payable by the Vendor as a result of the foregoing.
The Vendor shall do all things as are reasonably requested by the Purchaser to
enable the Purchaser to comply with its obligations hereunder in a timely and
efficient manner.

undivided interest in the Grouse Creek Assets, and is not otherwise required to

the net proceeds raised by the Purchaser from the Financing to pay the Purchase
Price and the Pre-Closing Development Costs.

for that portion of the proceeds from the Financing equal to the Escrowed
Amount to be held by an escrow agent on terms and conditions satisfactory to
the Purchaser and the Vendor, acting reasonably.

                  (c)       Approvals.  Great Lakes shall use best efforts to
obtain all listing and regulatory approvals required so that the common shares
of Great Lakes underlying the Warrants shall be listed for trading on The

payments shall be made to the Parties at such of the respective offices as the
parties may respectively designate in writing.

11.2              Waiver.  The failure of a Party in any one or more instances
to insist upon strict performance of any of the terms of this Agreement or to
exercise any right or privilege arising under it shall not preclude it from
requiring by reasonable notice that any other Party duly perform its
obligations or preclude it from exercising such a right or privilege under
reasonable circumstances, nor shall waiver in any one instance of a breach be
construed as an amendment to this Agreement or waiver of any later breach.  No
amendment to or waiver of any provision of this Agreement shall be effective
unless embodied in writing duly signed by a duly authorized representative of
each Party.

11.3              Severability.  If any of the terms or conditions set forth in
this Agreement are not enforceable, in whole or in part, the remaining terms
and conditions hereof may be enforced by the parties notwithstanding the
unenforceable term or condition.  Any term or condition not enforceable in part
may be enforced to the extent that it is valid and enforceable.  No failure or
delay by any party in exercising any right, power or privilege hereunder shall
operate as a waiver thereof nor shall any single or partial exercise thereof
preclude any other or further exercise hereof or the exercise of any right,
power or privilege hereunder.

11.4              Assignment.  Neither this Agreement nor any of the rights and
obligations of a Party hereunder may be assigned by such Party in whole or in
part without the prior written consent of the other Party, which consent may
not be withheld unreasonably.  This Agreement shall enure to the benefit of and
be binding upon the Parties hereto and their respective successors and
permitted assigns.

11.5              Further Assurances.  The Parties agree that they and each of
them will execute all documents and do all acts and things as may be necessary
or desirable within their respective powers to carry out and give effect to the
true intents and purposes of this
   51

Agreement including the execution after the Closing Date of such further
assignments, conveyances or assurances in law as the Purchaser deems necessary
or desirable to vest, perfect, confirm or record in the Purchaser the title or
other appropriate right to any of the Purchased Assets or to perfect the
completion of any of the transactions referred to in this Agreement.

11.6              Time of Essence.  Time is of the essence of this Agreement.

11.7              Counterparts.  This Agreement may be executed in one or more
counterparts each of which, when so executed, shall be deemed to be an original
and all of which when taken together shall constitute one and the same
agreement.

                  IN WITNESS WHEREOF the Parties hereto have duly executed this
Agreement effective as of the date first above written.
