Endeavour Silver Corp.: Production Growth Slows, Mine Development Accelerates, Temporary Mine and Mill Teething Problems Resolved

VANCOUVER, BRITISH COLUMBIA, Nov 29, 2005 (CCNMatthews via COMTEX) --

Endeavour Silver Corp. (TSX VENTURE:EDR)(FWB:EJD) -

High-Grade Silver Mineralization Outlined on Porvenir Dos and San Marcos Properties, Guanacevi Project, Durango, Mexico

Endeavour Silver Corp. announces that the rate of growth in silver production at the Guanacevi Project, Durango, Mexico has slowed in recent weeks as underground mining equipment and personnel were diverted from ore production to development headings in order to prepare for the next phase of production growth in 2006.

Various mine and mill "teething problems" cropped up during the most recent increase in production, which also caused a slowdown in silver production, but these issues have now been resolved. Specifically, a major mine supplier was until recently unable to deliver certain ground support parts and supplies on a timely basis. As a result, the highest grade stope in the North Porvenir mine was unnecessarily idle for several weeks. In addition, the mill closed for several days last week to repair two cone crushers and complete normal maintenance on the crushers.

As a result, recent silver production has plateaued at about 100,000 oz. per month, ahead of the Q2 performance but lower than the 125,000 oz. per month goal Endeavour has targeted. With these issues now resolved, the Company anticipates the rate of growth of silver production will once again increase to meet next year`s production targets.

Endeavour also announces that high-grade silver mineralization has been outlined by surface sampling of the Santa Cruz vein on the Porvenir Dos property and the San Vicente vein on the San Marcos properties, both recent additions to the Guanacevi Project, Durango, Mexico.

Porvenir Dos is located adjacent to and along strike from the Santa Cruz property to the northwest of the new North Porvenir mine. Endeavour holds an option to purchase a 100% interest in the Porvenir Dos and La Sultana properties for cash payments totalling US$137,500 over an 18-month period.

After optioning Porvenir Dos in August 2005, Endeavour completed a geological mapping and vein-sampling program over the 500 m long surface extention of the Santa Cruz vein. It is marked by old mine workings that exhibit varying amounts of fracturing, oxidation, silicification and quartz veining, up to 4 m wide in places but averaging 1 m thick.

The Santa Cruz vein is hosted by Tertiary andesitic volcanics near the contact with underlying Cretaceous conglomeritic sediments. The andesites display a broad zone of rusty white argillic alteration similar to the North Porvenir mineralized zone. The conglomerates host a sub-parallel, narrow vein that appears to be a splay off the Santa Cruz vein.

The mapping and sampling program on the Porvenir Dos property appears to confirm a relatively high level within the mineralized system, similar to the North Porvenir zone, where narrow veining occurs on surface but silver mineralization is relatively sparse and lower grade.

Notwithstanding, a total of 17 channel samples from vein outcrops on Porvenir Dos returned assays ranging up to 691 gpt silver and 0.8 gpt gold. Follow-up systematic channel samples collected approximately 5 m apart along a 200 m length of the vein from southeast to northwest returned the following assays:

Multiplying the gold grades in grams per tonne by 60 and adding them to the silver grade in grams per tonne is how the silver equivalents were calculated. This calculation takes into account the difference in price and metallurgical recoveries in the plant for both metals.

San Marcos is located sub-parallel to and approximately 3 km northeast of the Santa Cruz vein and the North Porvenir mine. Endeavour acquired a 100% interest in the San Marcos properties as part of the 9-property package purchased from Industrias Penoles in May 2005.

A mapping and sampling program similar to the Porvenir Dos property was conducted over the 1.2 km surface extent of the San Vicente vein. The property has a number of old mine workings that display quartz veining up to 10 m wide but averaging 1 m thick.

The San Vicente vein is also hosted by Tertiary andesitic volcanics near their contact with the underlying Cretaceous conglomeritic sediments, but dipping to the northeast rather than to the southwest. Like Porvenir Dos, the surface mineralization appears to be somewhat sporadic but 30 grab or channel samples from vein outcrops and mine dumps returned assays up to 789 gpt Ag and 2.0 gpt Au, as follows:

Sporadic but high grade silver vein mineralization at both Porvenir Dos and San Marcos is a good indicator of prospective but more continuous mineralization at depth. Endeavour is already drilling Porvenir Dos as part of the current drill program now underway on the Guanacevi Project. San Marcos will be drilled as part of the 2006 drill program.

Godfrey Walton, President, stated, "These two properties represent good examples of how old vein prospects can be developed into attractive drill targets in a relatively short period of time within the Guanacevi district. We anticipate developing several similar targets for drilling in 2006 as part of our ongoing exploration in the district."

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. Endeavour personnel at the Guanacevi Project camp split all core samples and assay them at the Guanacevi plant. Blanks and duplicates are introduced into the sequence and the samples are driven to Durango where they are couriered to the Chemex lab in Hermosillo. Samples are dried, crushed and split and a 30 gram (1 assay ton) sub sample is taken for analysis. Gold and silver at both Guanacevi and Chemex are determined by fire assay with an atomic absorption (AA) finish.

Endeavour Silver Corp. (TSX VENTURE:EDR)(FWB:EJD) is a silver mining company focused on the growth of its silver resources and production in Mexico. The expansion program now underway at the high grade Santa Cruz silver mine in Durango, Mexico, should allow Endeavour to become one of the top five primary silver producers in the world.
