Cumberland Submits Final Environmental Impact Study for Meadowbank Gold Project.

VANCOUVER, British Columbia -- CUMBERLAND RESOURCES LTD. (TSX:CLG)(AMEX:CLG) is pleased to report that it has submitted its Final Environmental Impact Statement (FEIS) to the Nunavut Impact Review Board (NIRB) for development permitting of the Company's 100% owned Meadowbank gold project located 70 kilometres north of the Hamlet of Baker Lake, Nunavut. The NIRB has acknowledged receipt of the FEIS, advancing Cumberland to the final stages of permitting. The Meadowbank project is a proposed open pit gold mine with a scheduled 12 year project life including two years of construction, over eight years of gold production and a two year closure period.

"We are pleased to see that such a comprehensive permitting process can maintain its high standards and remain on schedule. This is a reflection of the combined efforts of the regulators and our permitting team," commented Kerry Curtis, President and CEO of Cumberland. "With the progress made to date, we anticipate completion of the permitting process in early 2006 allowing the Company to consider a formal production decision."

Final Stages of Permitting

The NIRB, the leading authorizing agency, will now complete a technical review of the FEIS and hold public hearings within local communities. The NIRB will then submit its decision and assessment to the federal government leading to the issuance of the project certificate.

Cumberland is in the process of negotiating an Inuit Impact Benefits Agreement with the Kivalliq Inuit Association as a requirement for the development of the Meadowbank gold project. The agreement focuses on jobs, education and training, contracting and community initiatives.

Financial Adviser Arranging Financing Alternatives and Terms

Acting as exclusive financial adviser in connection with debt financing of Meadowbank, SG Corporate & Investment Banking (SG CIB)'s Mining Finance team (a division of Societe Generale Group) is arranging for a syndicate of financial institutions as prospective underwriters and arrangers of the debt financing. Cumberland hopes to complete SG CIB's mandate in early 2006.

Expanded Drilling Completed at Cannu Zone

The Phase III drill program, consisting of 12 holes, was completed at the new Cannu zone in the first week of November. The near surface, high grade mineralization at the Cannu zone is located 350 metres north of the proposed Portage open pit and represents additional near surface gold mineralization which may contribute to the resource and reserve potential of the project. Assay results from the Phase III drill program will be announced as received.

Low Cost Production Profile at Meadowbank

Meadowbank is forecast to produce 315,000 ounces of gold per year over an 8.3 year mine life with an estimated total cash cost of US$224 per ounce based on a feasibility study(1) completed in February 2005. Operations from three, shallow open pits are planned to commence in mid-2008 provided the permitting process is completed in early 2006.
