Endeavour Silver Corp.: Silver Resources Triple to
More Than 12 Million Ounces at Santa Cruz Mine,
Durango, Mexico

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 30, 2005) - Endeavour
Silver Corp. (TSX VENTURE:EDR) announces that as a result of the recent
successful exploration drilling programs, silver resources at the Santa
Cruz Mine in Durango, Mexico, have more than doubled to 934,000 ounces
of Silver in a Measured and Indicated resource categories and 3.84
million ounces of Silver in an Inferred resource Category at Porvenir
with a "historical resource" at Deep Santa Cruz that has been
recalculated to contain 8.0 million ounces of Silver.

Watts Griffis McOuat ("WGM") was retained to prepare an audit of the
resource estimate for the new North Porvenir discovery based on the
first 21 drill holes. WGM confirms that this resource estimate conforms
to Canadian Securities Regulation NI 43-101 guidelines and the
definitions of the Council of the Canadian Institute of Mining,
Metallurgy and Petroleum standards. The polygonal estimate of the
current resources in the Measured and Indicated categories totals 42,200
tonnes grading 689 gpt Ag and 1.2 gpt Au, containing 934,800 oz. silver.
The Inferred resource category totals 245,700 tonnes grading 486 gpt Ag
and 1.2 gpt Au, containing 3.839 million oz. silver. The Mineral
Resource is estimated using a 335 g/t Ag cutoff and a minimum mining
width of 1.0 meters with silver at $6.50 per oz.

This initial resource estimate must be considered preliminary as two
drill rigs continue to intercept high grade silver-gold vein
mineralization at North Porvenir along strike and down dip. The zone is
still open in all directions. Endeavour anticipates updating the
resource again later this year after more drilling is completed. The
resources in the North Porvenir zone to date are reported as follows:



---------------------------------------------------------------------
Classification Tonnes g Ag/t g Au/t Silver Oz
---------------------------------------------------------------------
Measured 18,700 698 1.2 420,000
---------------------------------------------------------------------
Indicated 23,500 682 1.2 514,800
---------------------------------------------------------------------
Measured and Indicated 42,200 689 1.2 934,800
---------------------------------------------------------------------

---------------------------------------------------------------------
Inferred 245,700 486 1.2 3.84 million
---------------------------------------------------------------------


Endeavour mine personnel also completed a re-calculation of the
"historic resource" reported by Industrias Penoles in the Deep Santa
Cruz zone based on 13 drill holes. A polygonal estimate of this historic
resource totals 357,000 tonnes grading 700 gpt Ag and 1.7 gpt Au,
containing 8.0 million oz. silver. The Deep Santa Cruz zone is open down
dip and to a certain extent along strike. This resource is viewed as
historical and is not NI 43-101 compliant and therefore should not be
relied upon. Endeavour plans to re-drill some of the Penoles
intersection to confirm grades and widths. The Company uses this
information as a guide to defining drill targets and developing
priorites for its exploration program. WGM has not reviewed or commented
on the resource estimate at Deep Santa Cruz. The resource in the Deep
Santa Cruz zone is reported as follows:



---------------------------------------------------------------------
Classification Tonnes g Ag/t g Au/t Silver Oz
---------------------------------------------------------------------
Historic possibly inferred 357,000 700 1.7 8.0 million
---------------------------------------------------------------------


This re-calculated resource is 100% higher than the Penoles estimate of
3.9 million oz. Ag equivalents contained in 229,000 tonnes grading 525
gpt Ag and 1.2 gpt Au. For the Deep Santa Cruz and North Porvenir zones
combined, the current 12 million oz. silver resource reflects an
increase of 200% compared to the historic 3.9 million oz. silver
resource at Deep Santa Cruz alone.

Endeavour plans to continue drilling at North Porvenir with two drill
rigs until this exciting new high grade zone of mineralization is fully
defined along strike, at which time one drill rig will continue step-out
to drilling up and down-dip. The second drill rig will move to test the
other seven mineralized zones identified on the Santa Cruz property.

Godfrey Walton, M.Sc., P.Geo., is the Qualified Person supervising the
surface drilling and underground sampling programs on the Santa Cruz
property. He has instituted a Quality Control sampling program of blanks
and duplicates to monitor the integrity of all assay results. All drill
core is split by Endeavour personnel at the Guanacevi camp and then
driven to Durango where it is couriered to the Chemex lab in
Guadalajara, Jalisco state. Core samples are dried, crushed, split and a
30 gram sub sample is taken for analysis. Gold and silver are determined
by fire assay with an atomic absorption (AA) finish.

Endeavour Silver Corp. (TSX VENTURE:EDR) is a small-cap exploration and
mining company focused on aggressively expanding its portfolio of high
grade silver-gold properties, reserves and production in Mexico. Canarc
Resource Corp. (TSX:CCM) holds a minority shareholding in the Company.

On Behalf of the Board of Directors,

ENDEAVOUR SILVER CORP.

Bradford J. Cooke, Chairman and CEO
