This is Schedule “C” to the Silver Purchase Agreement among
Zinkgruvan Mining AB, Silver Wheaton (Caymans) Ltd. and ▇▇▇▇▇▇ Mining Corporation
dated December 8^th, 2004

Dispute Resolution

The following rules and procedures shall apply with respect to any matter to be arbitrated by the Parties under the terms of the Agreement.

Initiation of Arbitration Proceedings

(a)

Any dispute, disagreement or claim arising out of or in connection with this Agreement that has not been resolved by the Parties within ten (10) Business Days of the delivery of notice by one Party to the other Party of such dispute, disagreement or claim shall be referred to binding arbitration and shall not be brought before any court of competent jurisdiction other than to obtain temporary injunctive relief under the equitable powers of such court. Subject to Section 1(b) below, such referral to binding arbitration shall be to three (3) qualified arbitrators (the “Arbitrators”). The International Commercial Arbitration Act (Ontario) shall govern such arbitration proceedings in accordance with its terms except to the extent modified in this Schedule “B”. The determination of the Arbitrators shall be final and binding upon the Parties and shall not be subject to appeal or review procedure and the costs of such arbitration shall be as determined by the Arbitrators. The Parties covenant that they shall conduct all aspects of such arbitration having regard at all times to expediting the final resolution of such arbitration.

(b)

If any Party wishes to have any matter under this Agreement arbitrated in accordance with the provisions of this Agreement, it shall give notice to the other Party hereto specifying particulars of the matter or matters in dispute and proposing the name of one person it wishes to be appointed an Arbitrator. Within ten (10) days after receipt of such notice, the other Party shall give return notice to the first Party proposing the name of a person it wishes to be appointed an Arbitrator. If such return notice is not given by the other Party within such ten (10) day period, it shall be deemed to have accepted the Arbitrator proposed by the first Party as the sole Arbitrator. If such return notice is given within such ten (10) day period proposing another person to be Arbitrator, the two proposed Arbitrators shall meet within ten (10) days of such second notice and select a third person to be the third Arbitrator and act as Chairman of the arbitration panel within five (5) days of such meeting. If said arbitrators shall be unable to agree on the selection of such third Arbitrator, then the arbitrators shall apply to the ADR Institute of Canada, Inc. for a list of arbitrators pursuant to Rule 15 of their National Arbitration Rules.

(c)

All Arbitrators so nominated or selected shall be qualified by education and who have sufficient industry experience in the subject matter of the dispute. The Arbitrators shall be at arm’s length from both Parties and shall not be past or

- 2 -

present officers, directors or employees of either Party or a member of the audit or legal firm or firms who advise either Party, nor shall the Arbitrators be persons who are regularly retained or have been retained in the preceding five (5) years before the matter in question arose by either of the Parties.

Submission of Written Statements

(a)

Within ten (10) days of the appointment of the Arbitrators, the Party initiating the arbitration (the “Claimant”) shall send the other Party (the “Respondent”) a statement of claim setting out in sufficient detail the facts and any contentions of law on which it relies, and the relief that it claims.

(b)

Within fifteen (15) days of the receipt of the statement of claim, the Respondent shall send the Claimant a statement of defence stating in sufficient detail which of the facts and contentions of law in the statement of claim it admits or denies, on what grounds, and on what other facts and contentions of law he relies.

(c)

Within ten (10) days of receipt of the statement of defence, the Claimant may send the Respondent a statement of reply.

(d)

All statements of claim, defence and reply shall be accompanied by copies (or, if they are especially voluminous, lists) of all essential documents on which the party concerned relies and which have not previously been submitted by any party, and (where practicable) by any relevant samples.

(e)

After submission of all the statements, the Arbitrators will give directions for the further conduct of the arbitration.

Meetings and Hearings

(a)

The arbitration shall take place in the City of Toronto, Ontario, or in such other place as the Claimant and the Respondent shall agree in writing. The arbitration shall be conducted in English. Subject to any adjournments that the Arbitrators allow, the final hearing will be continued on successive Business Days until it is concluded.

(b)

Subject to the provisions hereof, the decisions of the arbitrators of any two of them in writing shall be binding upon the parties both in respect of procedure and the conduct of the Parties during the proceedings and the final determination of the issues therein.

(c)

The majority of the arbitrators may determine any matters of procedure for the arbitration not specified herein.

(d)

All meetings and hearings will be in private unless the Parties otherwise agree.

(e)

Any Party may be represented at any meetings or hearings by legal counsel.

- 3 -

(f)

Each Party may examine, cross-examine and re-examine all witnesses at the arbitration.

The Decision

(a)

The Arbitrators will make a decision in writing and, unless the Parties otherwise agree, will set out reasons for decision in the decision.

(b)

The Arbitrators will send the decision to the Parties as soon as practicable after the conclusion of the final hearing, but in any event no later than twenty (20) days thereafter, unless that time period is extended for a fixed period by the Arbitrators on written notice to each Party because of illness or other cause beyond the Arbitrators’ control.

(c)

Subject to the discretion of the Arbitrators, the decision shall determine and award costs to the successful Party in the arbitration.

(d)

The decision shall be final and binding on the Parties and shall not be subject to any appeal or review procedure provided that the Arbitrators have followed the rules provided herein in good faith and have proceeded in accordance with the principles of natural justice. In the event either Party initiates any court proceeding in respect of the decision of the arbitration or the matter arbitrated, such Party shall, if unsuccessful in the court proceeding, pay the other Party's costs on a solicitor/client basis plus all other reasonable expenses incurred by such other Party from the date of delivery of the notice commencing arbitration to the date of determination of such court proceeding.

Jurisdiction and Powers of the Arbitrators

(a)

By submitting to arbitration under these Rules, the Parties shall be taken to have conferred on the Arbitrators the following jurisdiction and powers, to be exercised at the Arbitrators’ discretion subject only to these Rules and the relevant law with the object of ensuring the just, expeditious, economical and final determination of the dispute referred to arbitration.

(b)

Without limiting the jurisdiction of the Arbitrators at law, the Parties agree that the Arbitrators shall have jurisdiction to:

(i)

determine any question of law arising in the arbitration;

(ii)

determine any question as to the Arbitrators’ jurisdiction;

(iii)

determine any question of good faith, dishonesty or fraud arising in the dispute;

(iv)

order any Party to furnish further details of that Party’s case, in fact or in law;

- 4 -

(v)

proceed in the arbitration notwithstanding the failure or refusal of any Party to comply with these Rules or with the Arbitrators’ orders or directions, or to attend any meeting or hearing, but only after giving that party written notice that the Arbitrators intends to do so;

(vi)

receive and take into account such written or oral evidence tendered by the Parties as the Arbitrators determine is relevant, whether or not strictly admissible in law;

(vii)

make one or more interim awards;

(viii)

hold meetings and hearings, and make a decision (including a final decision) in Toronto, Ontario or elsewhere with the concurrence of the Parties thereto;

(ix)

order the Parties to produce to the Arbitrators, and to each other for inspection, and to supply copies of, any documents or other evidence or classes of documents in their possession or power which the Arbitrators determine to be relevant; and

(x)

make interim orders to secure all or part of any amount in dispute in the arbitration.

Access to Courts for Enforcement and Interim Remedies

(a)

The Parties consent to the award of the Arbitrators being entered into court of competent jurisdiction for the purposes of enforcement. In addition, if it appears to any Party that the Arbitrators lack the power to give effective interim relief, either Party may apply to any appropriate court of competent jurisdiction for such relief.

THIS SILVER PURCHASE AGREEMENT dated as of the 8th day of December, 2004.
