DISCLOSURE CONTROLS AND PROCEDURES

Lundin Mining Corporation (the Registrant) maintains disclosure controls and procedures designed to ensure that information required to be disclosed in the Registrant's filings under the Securities Exchange Act of 1934, as amended (the Exchange Act) is recorded, processed, summarized and reported within the time period specified in the rules and forms of the Securities and Exchange Commission (the SEC).  The Registrant's Chief Executive Officer and Chief Financial Officer have evaluated the effectiveness of the Registrant's disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this report and have concluded that, as of such date, the Registrant's disclosure controls and procedures were effective to ensure that information required to be disclosed by the Registrant in reports it files or furnishes under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC.  However, as recommended by the SEC in its adopting release, the Registrant will continue to periodically evaluate its disclosure controls and procedures and will make modifications from time to time as deemed necessary to ensure that information is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms.

Except as disclosed under Evaluation of Disclosure Controls and Procedures and Internal Controls over Financial Reporting of the Registrant's Management's Discussion and Analysis of Results of Operations and Financial Condition, which is an exhibit to this Annual Report on Form 40-F, there was no change in the Registrant's internal control over financial reporting that occurred during the period covered by this report that has materially affected, or is reasonably likely to materially affect, its internal control over financial reporting.

Report On Internal
Control Over Financial Reporting

This Annual Report
on Form 40-F does not include
a report of management's assessment regarding internal control over financial
reporting or an attestation report of the company's registered public accounting
firm due to a transition period established by rules of the SEC for newly public companies.

AUDIT COMMITTEE FINANCIAL EXPERT

The Registrant's Board of Directors has determined that all members of the Audit Committee of the Board of Directors are financially literate within the meaning of the American Stock Exchange's listing standards and that at least one member serving on its Audit Committee qualifies as an audit committee financial expert as such term is defined in the rules and regulations under the Exchange Act.  Mr. Dale C. Peniuk has been determined to be such audit committee financial expert and is independent, within the meaning of the American Stock Exchange's listing standards applicable to the Registrant.

The SEC has indicated that the designation of Mr. Dale C. Peniuk as an audit committee financial expert does not make him an expert for any purpose, impose on him any duties, obligations or liability that are greater than the duties, obligations or liability imposed on him as a member of the Audit Committee and the Board of Directors in absence of such designation, or affect the duties, obligations or liability of any other member of the Audit Committee or Board of Directors.

CODE OF ETHICS

The Registrant has adopted a Code of Ethics entitled Code of Conduct and Ethical Values Policy that applies to all directors, officers and employees of the Registrant, including its principal executive officer and principal financial officer.

AUDIT COMMITTEE'S PRE-APPROVAL POLICIES AND PROCEDURES

The Registrant's Audit Committee pre-approves all audit services and permitted non-audit services provided to the Registrant by PricewaterhouseCoopers LLP. The Audit Committee has delegated to the Chair of the Audit Committee, who is independent, the authority to act on behalf of the Audit Committee with respect to the pre-approval of all audit and permitted non-audit services provided by its external auditors from time to time.  Any approvals by the Chair are reported to the full Audit Committee at its next meeting.  All of the services described in the Annual Information Form under Principal Accountant Fees and Services under the captions Audit-Related Fees, Tax Fees and All Other Fees were approved by the Audit Committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.
