Cumberland Announces 2005 Meadowbank Exploration

RESOURCES LTD. (TSX:CLG)(AMEX:CLG) is pleased to announce a budget of
$3.5 million for the 2005 exploration program on the Company's 100%
owned Meadowbank gold project located in Nunavut, Canada. The two phased
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 at Meadowbank.

Cumberland is advancing Meadowbank towards production after a
feasibility study(i) completed in February 2005 (see news release
NR05-02) indicated the project could support a production rate of
316,000 ounces per year at an estimated cash cost of US$224 per ounce
over an 8.3 year mine life.

Meadowbank Gold Project Production Profile(i)
Open Pit Mineral Reserves 2,768,000 ounces
(Proven and Probable)
Mine Throughput 2.73 Mtpa
Mine Life 8.3 years
Average Annual Production Rate
Years 1 to 4 376,000 ounces
Life of Mine 316,000 ounces
Total Cash Cost per Oz.
Years 1 to 4 US$199
Life of Mine US$224
Estimated Start of Operations+ mid-2008
Assumptions include a long term gold price of US$400/oz
and an exchange rate of US$0.75 per Cdn$1.00.
+Assuming final permits and licenses obtained in early 2006.

"Meadowbank is host to the largest pure-gold open pit reserves
established in Canada, providing the Company with a solid economic basis
to emerge as an intermediate level gold producer," said Kerry Curtis,
President and CEO. "Historically, exploration at Meadowbank has
consistently returned additional resources, achieving a remarkable
discovery cost of approximately US$12 per reserve ounce gold. The 2005
exploration program will focus on the considerable opportunities that
exist to expand the 2.8 million ounce reserve and further improve the
economics of the project by extending the operational life of the mine."

The proven and probable reserve estimate for the three, shallow open
pits proposed at Meadowbank is as follows:

Goose 2,247,000 5.09 368,000
Total 21,896,000 3.93 2,768,000

2005 Planned Exploration Program

The 2005 Meadowbank 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 up to 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.

2005 Exploration Targets (See Attached Maps)

Expansion of the Goose Island Deposit: Significant potential exists to
expand the Goose Island deposit (368,000 ounces of gold reserves) both
along strike and in the down dip direction. The 2005 drilling will
follow up on significant results from drilling in 2004 including:

Downdip extensions: Hole G04-521: 8.43 g/t gold over 5.83 metres
at 80 metres below surface
Hole G04-509: 12.72 g/t over 11.25m at 85m
below surface
South strike extensions: Hole G04-527: 87.88 g/t over 4.91m at 50m
below surface
North strike extensions: Hole G04-523: 18.28 g/t over 0.94m at 50m
below surface
And: 1.72 g/t over 10.11m

South of the Goose Island Deposit: The Goose Island South target area is
located approximately 300 metres south of the proposed Goose Island open
pit. The target covers approximately 850 metres of prospective iron
formation along strike from the Goose Island deposit. Previous wide
spaced drilling completed in 1995 and 1997 intersected mineralization

Hole G97-172: 3.77 g/t gold over 3.30 metres
at 382 metres below surface
Hole G97-171: 2.37 g/t over 3.00m at 276m
below surface
Hole G95-073: 3.37 g/t over 5.00m at 72m
below surface
Incl: 6.78 g/t over 1.00m

Expansion of the PDF Deposit: The PDF deposit, located 10 kilometres
north of the Vault proposed open pit, was expanded by drilling in late
2004. The deposit now hosts inferred gold resources(iii) of 73,000
ounces of gold in 507,000 tonnes grading 4.50 g/t gold, which are not
included in the current mine plan. Wide spaced drilling in 2005 will
focus on the expansion potential of the deposit in the down dip
direction and follow up on significant results from the 2004 program,

Hole PDF04-035: 5.60 g/t gold over 3.02
metres at 125 metres below surface
Hole PDF04-036: 6.79 g/t over 2.51m at 132m
below surface
Incl: 13.00 g/t over 1.26m
