SUMMARY OF RECENT ACTIVITIES

Final Stages of Permitting

Cumberland advanced to the final stages of permitting by submitting the Final Environmental Impact Statement (FEIS) to the Nunavut Impact Review Board (NIRB) in early November (see news release 05-14). 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.

Discovery of Near Surface Cannu Zone

The Phase II 2005 drill program intersected near surface, high grade mineralization (see news release 05-13) at the new Cannu zone (see news release 05-11). The Cannu zone is located 350 metres north of the proposed Portage open pit, which contains the largest reserves (1.5 million ounces(2)) of the three proposed open pits at Meadowbank. Phase II drilling at the Cannu zone (18 holes) indicates the continuous nature of the Portage mineralization beyond the current open pit design towards the Cannu zone.

Expanded 2005 Drill Program to Increase Reserves and Resources

Based on the high grade drill results from the new Cannu zone, a Phase III drill program was added to assess the expansion potential of the Cannu zone (see news release 05-12). The Cannu zone represents additional near surface gold mineralization which may contribute to the resource and reserve potential of the project. The Phase III drill program commenced in the first week of October and drilling was completed in the first week of November. Assay results from the Phase III drill program will be announced as received.

The Phase I (7,800 metres in 53 holes) and Phase II (2,700 metres in 25 holes) programs were successful in expanding the size of the Goose Island deposit, intersecting encouraging mineralization in the Goose Island South area and discovering the Cannu zone. The Phase III drill program at the Cannu zone includes an additional 12 drill holes (1,200 metres), bringing the total amount of 2005 drilling at Meadowbank to almost 12,000 metres. Prior to 2005 drilling, Meadowbank gold resources contained an estimated 3,326,000 ounces of measured and indicated resources3 and 474,000 ounces of inferred resources3 (first quarter 2005).

Construction of an airstrip at Meadowbank with planned capacity to handle light fixed wing aircraft commenced in July. The airstrip has improved access to the property in support of ongoing exploration programs.

Financial Adviser Arranging Financing Alternatives and Terms

SG Corporate & Investment Banking ("SG CIB")'s Mining Finance team (a division of Societe Generale Group) was awarded a pre-arranging advisor mandate in June 2005 (see news release 05-07) to act as exclusive financial adviser in connection with debt financing of Meadowbank. Cumberland hopes to complete SG CIB's mandate in early 2006.

SG CIB is arranging for a syndicate of financial institutions as prospective underwriters and arrangers of the debt financing of the Meadowbank project. In addition, SG CIB has appointed an independent engineer to perform a technical audit on behalf of potential lenders with respect to the feasibility study1 completed for Cumberland by AMEC Americas Ltd. in February 2005.

FINANCIAL HIGHLIGHTS

At September 30, 2005 the Company had working capital of $29.8 million compared to $37.0 million at December 31, 2004.

The Company incurred a net loss of $2.7 million ($0.05 per share) in the third quarter of 2005 compared to $3.7 million ($0.07 per share) in the third quarter of 2004. This decrease in net loss is primarily due to the reduction in stock-based compensation expense during the third quarter, partially offset by increases in project financing costs.

The largest component of the Company's net loss relates to exploration and development costs at the Meadowbank project. In the third quarter of 2005 the Company incurred exploration and development costs at Meadowbank of $2.1 million which is consistent with the costs incurred in the third quarter of 2004.

The Company had no operating revenues in the third quarters of 2005 or 2004, as it had not commenced mining operations.

This summary of financial highlights should be read in conjunction with the Company's third quarter 2005 unaudited financial statements and Management's Discussion and Analysis of Financial Condition and Results of Operations, both of which are available on www.sedar.com.
