Cumberland Reports 2004 Financial Results and Summary of Activities.

VANCOUVER, British Columbia -- CUMBERLAND RESOURCES LTD. (TSX:CLG)(AMEX:CLG) is pleased to report audited financial results for the year ended December 31, 2004, and summary of activities to date.

SUMMARY OF RECENT ACTIVITIES

On February 24, 2005, Cumberland announced the results from the Feasibility Study ("Study") on the Company's 100% owned Meadowbank Gold Project located in Nunavut, Canada. Initiated in 2003, completion of the Study was extended in early 2004 due in part to global escalations in the cost of fuel, steel and other construction items which impacted the preliminary construction cost estimates for the project. The Study incorporates improvements to the Meadowbank mine model as a result of a re-design completed in 2004 by the Company and the study manager, AMEC Americas Ltd. ("AMEC"). The most significant improvements are from increased annual production and mill throughput, changes to open pit scheduling, and a proposed 102 km conventional access road to connect the project to the community of Baker Lake.

The Study results evaluate an open-pit gold mine and assume a gold price and exchange rate of US$400 per ounce and US$0.75 per Cdn$1.00 respectively and full equity financing. According to the Study, Meadowbank is projected to produce an average of more than 300,000 ounces of gold per year over an 8.3 year mine life. Peak production is achieved in Year 1 of operations with 421,000 ounces produced from the Portage pit. Additional financial projections reflected in the Study include:

Conventional open pit mining methods will be used to exploit the
reserves of the project. The proven and probable open pit reserve

On March 15, 2005, Cumberland announced a budget of $3.5 million for the 2005 exploration program on the Meadowbank Project. The program, including a planned 7,000 to 9,000 metre diamond drilling program, is expected to commence in April and will focus on increasing gold reserves and resources. The exploration program will consist of a two phased drill program, subject to the availability of third-party drillers, and grassroots exploration along the 25 kilometre Meadowbank gold trend. At the Goose Island deposit, the Phase I drill program will focus on expansion of high grade intersections yielded in the 2004 drill program. South of the Goose Island deposit, drilling will test an 850 metre strike length of stratigraphy where previous wide spaced drilling has intersected gold mineralization similar to the Goose Island deposit. The Phase I program will also focus on the PDF deposit, which remains open for expansion at depth. The Phase II program will consist of approximately 2,000 metres of drilling, grassroots exploration on favourable structures north of the Vault deposit, and follow-up exploration on numerous recently defined prospects situated both near the proposed open pits and across the property.

The development of the Meadowbank Project is being reviewed under a NIRB Part 5 review as provided under Article 12 of the Nunavut Land Claims Agreement and existing Federal legislation. The Company has submitted a Draft Environmental Impact Study ("DEIS") to the Nunavut Impact Review Board ("NIRB"). The report identifies the potential impacts the Meadowbank Project will have on the local environment, socio-economic impacts, and the management and mitigation measures required to minimize the impacts of the project while maximizing the benefits. The NIRB is presently reviewing the DEIS and following a period of review and initial hearings, Cumberland will prepare a final EIS document, which will include responses to matters raised through the NIRB review period. The Company anticipates it could move into the Final EIS stage in the fall of 2005. Final approvals and licenses are anticipated in early 2006.

The engineering and construction schedule for the project assumes that all necessary NIRB approvals and licenses are obtained in early 2006 allowing procurement and shipping of equipment and supplies in the 2.5 month 2006 shipping season (mid-July to late September). Construction of the access road from Baker Lake to the Meadowbank site would commence in the fall of 2006. Upon completion of the access road a mine construction period of 18 months is required with production commencing in mid-2008.

Cumberland also holds a 22% interest (carried to production) in the Meliadine West gold project located in Nunavut Territory. Comaplex Minerals Corp. is the Operator of the Meliadine West gold project. Primary activities during 2004 at Meliadine West included ongoing resource evaluation of the Main Tiriganiaq deposit and further exploration of deeper targets (West Tiriganiaq zone) in preparation for feasibility study. A surface drill program consisting of 21 holes in 9,297 metres was completed by the Operator in September, 2004. The Operator reported that results from the final drill holes in the West Tiriganiaq zone indicate potential for additional gold resources at depth and along strike of the Main Tiriganiaq deposit. The Operator further stated it intends to recalculate resources in the Main Tiriganiaq deposit and perform subsequent exploration with the goal of moving this deposit towards feasibility as quickly as possible.

FINANCIAL HIGHLIGHTS

At December 31, 2004, the Company had working capital of $37.0 million as compared to $45.8 million at December 31, 2003.

The Company incurred a net loss of $10.5 million for the year-ended December 31, 2004, compared to a net loss of $13.4 million for the year-ended December 31, 2003. The reduction in net loss during 2004 is primarily attributable to a $2.5 million reduction in exploration and development costs and a $1.5 million increase in the gain on investments in public companies, which were partially offset by increases in stock-based compensation expense and general and administrative and other expenses.

The Company had no operating revenues in either 2004 or 2003, as it had not commenced mining operations. In both 2004 and 2003, the Company received the annual $500,000 option payment from the operator of the Meliadine West joint venture in accordance with an option agreement signed in 1995.

The most significant component of the Company's net loss for both 2004 and 2003 was exploration and development costs related to Meadowbank. During the years ending December 31, 2004 and December 31, 2003, the Company incurred exploration and development costs of $9.0 million and $11.2 million respectively on the Meadowbank project. The $2.2 million reduction in 2004 is primarily attributable to reduced exploration costs at Meadowbank. Consulting engineering costs related to completion of the Meadowbank feasibility study were also lower in 2004 than in the prior year.

This summary of financial highlights should be read in conjunction with the Company's 2004 audited financial statements and Management's Discussion and Analysis of Financial Condition and Results of Operations, both of which are available on www.sedar.com.
