EXPLANATORY NOTE



Cumberland Resources Ltd.(the Company) is a Canadian issuer that is permitted, under the multijurisdictional disclosure system adopted in the United States, to prepare its Annual Report pursuant to Section 13 of the Securities Exchange Act of 1934 (the Exchange Act) in accordance with disclosure requirements in effect in Canada which differ from those of the United States. The Company is a foreign private issuer as defined in Rule 3b-4 under the Exchange Act and in Rule 405 under the Securities Act of 1933.



FORWARD-LOOKING STATEMENTS



This Annual Report and the Exhibits included herein include certain forward looking information within the meaning of the Ontario Securities Act or forward looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934 of the United States.  Forward looking statements are subject to a variety of risks and uncertainties which could cause actual events or results to differ from those reflected in the forward looking statements, including, without limitation, risks and uncertainties relating to the interpretation of drill results and the estimation of mineral resources and reserves, the geology, grade and continuity of mineral deposits, the possibility that future exploration, development or mining results will not be consistent with the Companys expectations, metal recoveries, accidents, equipment breakdowns, title matters and surface access, labour disputes or other unanticipated difficulties with or interruptions in production, the potential for delays in exploration or development activities or the completion of new or updated feasibility studies, the inherent uncertainty of production and cost estimates and the potential for unexpected costs and expenses, commodity price fluctuations (including gold, fuel, steel and construction items), currency fluctuations, failure to obtain adequate financing on a timely basis and other risks and uncertainties, including those described in the Companys Annual Information Form filed as Exhibit 1 to this Annual Report on Form 40-F, under the heading "Narrative Description of Business - Risk Factors''. Forward-looking information is in addition based on various assumptions including, without limitation, the expectations and beliefs of management, the assumed long term price of gold, that the Company will receive required permits and access to surface rights, that the Company can access financing, appropriate equipment and sufficient labour and that the political environment within Nunavut and Canada will continue to support the development of environmentally safe mining projects so that the Company will be able to commence the development of the Meadowbank Project within the timetable to be established in the Study. Should one or more of these risks and uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described in forward-looking statements. Accordingly, readers are advised not to place undue reliance on forward-looking statements.



RESERVE AND RESOURCE ESTIMATES



All estimates of mineral reserves and resources incorporated by reference in this Annual Report have been prepared in accordance with Canadian National Instrument 43-101 (NI 43-101) and the Canadian Institute of Mining and Metallurgy Classification System.  These standards differ significantly from the requirements of the United States Securities and Exchange Commission (SEC).  Accordingly, information concerning descriptions of mineralization, reserves and resources contained in this Annual Report may not be comparable to information from U.S. companies subject to the SECs reporting and disclosure requirements.  In particular, the term resource does not equate to the term reserves.  The definitions of proven and probable reserves used in NI 43-101 differ from the definitions in SEC Industry Guide 7.  Under U.S. standards, mineralization may not be classified as a reserve unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made.  The SECs disclosure standards normally do not permit the inclusion of information concerning measured, indicated, or inferred mineral resources in documents filed with the SEC, unless such information is required to be disclosed by the laws of the Companys principal jurisdiction or of a jurisdiction in which its securities are traded.  U.S. Investors should also understand that inferred mineral resources have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimated inferred mineral resources may not form the basis of feasibility or pre-feasibility studies except in rare cases.  Readers are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable.  Disclosure of contained ounces is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report resources as in-place tonnage and grade



CURRENCY



Unless otherwise indicated, all dollar amounts in the Annual Report on Form 40-F are Canadian dollars.  On December 30, 2005, the noon buying rate in the City of New York for cable transfers in Canadian dollars as certified for customs purposes by the Federal Reserve Bank of New York was Canadian $1.00 = U.S. $0.8579, and on December 31, 2004, the rate was Canadian $1.00 = U.S. $0.8310.

NOTES:



(1)  Audit Fees represent fees for the audit of the Companys annual financial statements and review of the Companys interim financial statements billed and related to the last two fiscal years.



(2)  Audit-Related Fees represent fees for assurance and related services that are related to the performance of the audit or review of the Companys financial statements, principally for consultation regarding internal control reporting and translation services.



(3)  Tax Fees represent fees for Canadian corporate tax advice.





The Audit Committee has adopted procedures requiring Audit Committee review and approval in advance of all particular engagements for services provided by the Companys independent auditors.  The Audit Committee establishes fee levels or budgeted amounts for all services expected to be provided by the independent auditor.  Any proposed engagements exceeding these levels or amounts, as well as any type of services which has not received general pre-approval, will require specific pre-approval by the Audit Committee.  Consistent with applicable laws, the procedures permit limited amounts of services, other than audit, review or attest services, to be approved by one or more members of the Audit Committee pursuant to authority delegated by the Audit Committee, provided the Audit Committee is informed of each particular service at the next scheduled Audit Committee meeting.  All of the engagements and fees for 2005 were pre-approved by the Audit Committee.  The Audit Committee reviews with Ernst & Young LLP whether the non-audit services to be provided are compatible with maintaining the auditors independence.

The Company has no off-balance sheet arrangements required to be disclosed in this Annual Report on Form 40-F.

The required disclosure is included under Section 4 Liquidity and Capital Resources of Managements Discussion and Analysis of Financial Condition and Results of Operations for the year ended December 31, 2005, which is included herein as Exhibit 3.





AMEX CORPORATE GOVERNANCE



The Companys common shares are listed on the American Stock Exchange (AMEX).  Section 110 of the AMEX Company Guide permits AMEX to consider the laws, customs and practices of foreign issuers in relaxing certain AMEX listing criteria, and in granting exemptions from AMEX listing criteria based on these considerations.  A company seeking relief under these provisions is required to provide written certification from independent local counsel that the non-complying practice is not prohibited by home country law.  A description of the significant ways in which the Companys governance practices differ from those followed by domestic companies pursuant to AMEX standards is contained on the Companys website, www.cumberlandresources.com.
