Cumberland Reports Initial 2005 Drill Results and Commences Phase II Exploration Program at Meadowbank Gold Project

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - July 11, 2005) - CUMBERLAND RESOURCES LTD. (TSX:CLG)(AMEX:CLG) is pleased to report drill results from the Phase I 2005 drill program at the Company's 100% owned Meadowbank gold project located 70 kilometres north of the Hamlet of Baker Lake, Nunavut. The 2005 program is focused on increasing gold reserves and resources at Meadowbank, which is host to Canada's largest pure gold open pit reserves. The Phase I 2005 program has completed approximately 7,300 metres of diamond drilling in 47 holes at the Goose Island deposit, the Goose Island South target and the PDF deposit. Phase II of the 2005 Meadowbank exploration program is commencing with drilling scheduled to start in approximately three weeks. Initial drilling efforts will be focused on near surface mineralization intersected in 1998 drilling, located approximately 285 metres north of the proposed Portage open pit (1,534,000 ounces of gold reserves (1)). In addition, the Company will commence construction of an airstrip at Meadowbank to support ongoing exploration efforts.

Phase I drill results and drill hole location maps for the Goose Island deposit, Goose Island South target and the PDF deposit are attached to this release.

Goose Island Deposit - Definition and Depth Assessment Drilling

Drilling at the Goose Island deposit (368,000 ounces of gold reserves(1)) focused on further defining the near surface portions of the deposit along strike in both directions, assessing the high grade potential of the deposit below the current open pit design and improving the quality of the resources and reserves. The 2005 program included 28 drill holes to assess these targets. (See figure.)

Highlights from the 2005 drill program at the Goose Island deposit include:



South limit
definition: Hole G05-552: 3.94 g/t over 9.13 m at 12 m below surface
Hole G05-554: 7.58 g/t over 3.66 m at 21 m below surface
Hole G05-558: 10.97 g/t over 3.86 m at 28 m below
surface
North limit
definition: Hole G05-535: 10.09 g/t over 1.79 m at 22 m below
surface
Hole G05-536: 14.90 g/t over 1.90 m at 19 m below
surface
Hole G05-556: 3.37 g/t over 5.98 m at 62 m below surface
Below pit: Hole G05-537: 5.36 g/t over 13.07 metres at 98 metres
below surface
Hole G05-540: 7.31 g/t over 11.96 m at 108 m below
surface
Hole G05-546: 189.78 g/t over 1.80 m at 144 m below
surface
Hole G05-555: 8.04 g/t over 2.20 m at 192 m below
surface
Hole G05-566: 8.25 g/t over 2.50 m at 180 m below surface


Drilling on the northern and southern flanks of the Goose Island deposit has returned intersections that are expected to improve the quality and size of the Goose Island resources and reserves.

Seven holes were drilled on the shallow southern flank of the deposit to follow up on high grade drill results from 2004. The 2005 holes returned strong grades (from 3.2 g/t up to 10.97 g/t) over better than expected widths (2.48 metres to 9.13 metres). These results are expected to improve the quality of the resources in this portion of the deposit and have extended the limits of the deposit approximately 50 metres to the south.

On the shallow northern flank of the deposit 11 holes were drilled. Six of these returned significant intersections, including four holes that have extended the deposit to the north by approximately 50 metres. The two other holes, at depths of 22 metres and 19 metres below surface, returned high grade values (10.09 g/t and 14.90 g/t) that are expected to improve resource and reserve quality.

Ten holes were drilled to assess the resource potential below the proposed Goose Island open pit, a majority of which yielded intersections with gold grades of greater than 5.00 g/t. Hole G05-546 returned the highest gold value grading 189.78 g/t over 1.8 metres. Several of these intersections which are below the current pit design indicate a resource with potential for future underground mining.

Goose Island South Target - Exploration Drilling

Drilling on the Goose Island South target was designed to follow up on mineralization intersected in wide spaced drilling completed in 1995 and 1997. The program covered approximately 1,400 metres of prospective iron formation, along which 11 holes were drilled in the 2005 program. (See figure.)

Highlights from the 2005 drill program at the Goose Island South target include:



Hole G05-543: 4.15 g/t over 2.59 m at 50 m below surface.
Hole G05-567: 13.50 g/t over 0.40 m at 90 m below surface, and
2.60 g/t over 1.00 m at 137 m below surface.


Drilling in 2005, 550 metres south of the Goose Island deposit, followed up on a deep intersection from 1997 (2.64 g/t over 3.00 metres at 277 metres below surface in hole G97-171). Hole G05-543 returned an encouraging 4.14 g/t over 2.59 metres at a shallow depth (50 metres below surface or 150 metres up dip from the intersection in G97-171). Potential exists for additional mineralization in the vicinity of this drill hole, as the nearest drilling is 150 metres along strike in both directions.

While narrow high grade results from drill hole G05-567 suggest that there is potential for high grade mineralization in this area, most other 2005 Goose South drill holes encountered narrow and low grade mineralized intercepts.

PDF Deposit - Depth Extension Drilling

Wide spaced drilling at the PDF deposit (73,000 ounces inferred resource(2)), located 15 kilometres north of the proposed Goose Island open pit, was designed to test the depth potential of the deposit as follow up to significant results from the 2004 program. Eight wide spaced holes were drilled in 2005 to test for depth extensions. (See figure.)

Highlights from the 2005 drill program at the PDF deposit include:



Hole PDF05-042: 1.92 g/t over 6.35 m at 164 m from surface.
Hole PDF05-043: 6.77 g/t over 2.30 m at 148 m from surface.


Holes PDF05-042 and PDF05-043 were successful in intersecting the PDF mineralized zone 100 metres down dip from 2004 intersections; however, a second series of 100 metre down dip step outs failed to return any significant values, effectively closing off the mineralized trend.

2005 Phase II Exploration Program

The 2005 Phase II exploration program is commencing with evaluation of a number of targets on the Meadowbank property through prospecting, till sampling and Induced Polarization geophysical surveys. In addition, Cumberland plans to carry out 2,000 metres of diamond drilling which will include follow up on shallow mineralization intersected in 1998 drilling, located 285 metres north of the proposed Portage open pit. Drill hole NP 98-305 intersected 4.41 g/t over 6.65 metres from 4.70 metres to 11.35 metres down hole. Potential extensions of this mineralization to the north, south and at depth will be evaluated by the Phase II drill program.

2005 Airstrip Construction

Construction of an airstrip with capacity to handle light fixed wing aircraft will commence towards the end of July. The airstrip construction will be managed by Tercon Construction Ltd. and is designed to improve access to the property in support of ongoing exploration programs.

Meadowbank Gold Project

Cumberland is advancing Meadowbank towards open pit production of 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. A feasibility study (3) was completed by AMEC Americas Ltd. in February 2005, SG Corporate & Investment Banking was appointed Financial Adviser in June 2005 in connection with potential debt financing, and development permitting is progressing. Operations from three, shallow open pits are planned to commence in mid-2008, provided final permits and licenses are obtained in early 2006.
