Endeavour Silver Drilling Extends High Grade Silver-Gold Mineralization in Three New Zones at Guanajuato Mines Project in Guanajuato State, Mexico

Vancouver, Canada - December 2, 2008 - Endeavour Silver Corp. (EDR: TSX, EJD: DBFrankfurt and EXK: AMEX) announces that exploration drilling near its Bolanitos mines at the Guanajuato Mines project in Guanajuato State, Mexico has extended high grade silver-gold mineralization within three recently discovered vein zones, Bolanitos, Santa Maria and Lucero.

Endeavour acquired the Guanajuato Mines project in May, 2007 and commenced systematic drilling of the numerous veins on the property late last year in order to boost the silver-gold resources and increase mine production to the Bolañitos plant. Endeavour is currently producing about 400 tonnes per day of ore from both the Cebada mines in the eastern part of the Guanajuato mines project, and from the Bolanitos mines in the western part of the Guanajuato mines project.

The Bolanitos vein mineralization has now been extended an additional 250 meters along strike to the south, and the Santa Maria vein mineralization has been traced some 200 m long below the old mine workings. In addition, the San Jose FW (now called Lucero) vein is a new discovery that has been traced for 100 m thus far. All three zones appear to be wide open along strike and down dip.

Drilling highlights include many intervals with economic potential, including 166 grams per tonne silver and 5.54 gpt gold over 6.00 m (17.0 oz per ton silver equivalent over 19.7 feet), including 239 gpt silver and 11.45 gpt gold over 1.90 m (32.0 opt silver equivalent over 6.6 ft), in drill hole BSV-3, and 1015 gpt silver and 1.60 gpt gold over 0.9 m (33.1 opt silver equivalent over 3.0 ft) in hole BUV-9. 

Bradford Cooke, Chairman and CEO, stated, "We are encouraged by the ongoing success of our exploration team at Guanajuato. In less than one year of drilling, they have discovered multiple new zones of high grade silver-gold mineralization. At Cebada, the "3785" discovery was the first new find identified this year and it is now being developed for mining next year. At Bolanitos, the recent Bolanitos, Santa Maria and Lucero discoveries are all open for expansion and Lucero is already being developed for mining this year. These veins extend for several kilometres on Endeavour's properties and the potential for making additional high grade silver-gold discoveries appears to be very good."

High grade silver-gold mineralization has been intersected in fifteen drill holes on three separate veins to the south of Endeavour's operating Bolanitos mine at Guanajuato, as follows:

Endeavour is currently mining ore from the Bolanitos and Santa Maria veins at the operating Bolanitos mine. The new high grade drill intercepts in the Bolanitos and Santa Maria veins are close to existing mine workings and they can be readily accessed for mining by extending the existing ramps a short distance. 

To see the Bolanitos drill hole location map, please click here.

The SJS drill holes are important because they intersected the brand new, well-mineralized Lucero vein in the footwall to the main San Jose vein (previously mined by Industrias Penoles) that dips in the opposite direction to the San Jose vein. The Lucero vein was previously undiscovered but Endeavour's drill intercepts are close to existing mine workings so a crosscut has already been driven over to the Lucero vein and drifts have now progressed along the vein about 9 m in each direction.

At 9.0 m to the northwest, underground sampling in the Lucero vein returned 1,048 gpt silver and 2.7 gpt gold over 2.1 m width (36.5 opt silver equivalent over 6.9 ft), and at 9.7 m to the southeast, underground sampling assayed 338 gpt silver and 1.9 gpt gold over 2.7 m width (14.0 opt silver equivalent over 8.9 ft). The southeast heading has another 20 m to go in order to reach drill hole SJS-1. This area will be in production starting in December.

An updated NI 43-101 reserve and resource estimate is planned for the Guanajuato mine project after year-end and will include each of the new discovery areas. Mine production has been rising sharply since June and is on track to reach the plant capacity of 500 tonnes per day as scheduled by year-end.

Barry Devlin, M.Sc., P.Geo. Vice President Exploration is the Qualified Person who reviewed this news release and supervised the surface drilling and sampling programs at the Parral, Guanacevi and Guanajuato Projects. A Quality Control sampling program of reference standards, blanks and duplicates has been instituted to monitor the integrity of all assay results. All core samples are split at the Parral, Guanajuato, or Guanacevi field offices and shipped to ALS-Chemex Labs, where they are dried, crushed, split and 50 gram pulp samples are prepared for analysis. Gold and silver are determined by fire assay with an atomic absorption (AA) finish and lead, zinc and copper are determined by AA.

Endeavour Silver Corp. (EDR: TSX, EXK: AMEX, EJD: DBFrankfurt) is a small-cap silver mining company focused on the growth of its silver production, reserves and resources in Mexico. The expansion programs now underway at Endeavour's two operating mines, Guanacevi in Durango State and Guanajuato in Guanajuato state, coupled with the Company's acquisition and exploration programs in Mexico should enable Endeavour to join the ranks of top primary silver producers worldwide.
