Endeavour Silver 2010 Exploration Review and Exploration Plans for 2011

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 1, 2011) - Endeavour Silver Corp. (TSX:EDR)(NYSE Amex:EXK)(DBFrankfurt:EJD) released today its review of exploration results in 2010 and its exploration plans for 2011. The Company's exploration drilling programs in Mexico met with continued success in 2010, highlighted by the discovery of new, high grade silver-gold mineralized zones near Endeavour's two silver mining operations, Guanacevi Mines in Durango State, and Guanajuato Mines in Guanajuato State.

Barry Devlin, Vice President of Exploration, commented, "Last year, our talented exploration team once again delivered some exciting new silver-gold vein discoveries which will be included in our next NI 43-101 reserve/resource estimate expected in a few weeks time. Endeavour drilled approximately 41,400 meters (136,000 feet) in 148 drill holes testing multiple exploration targets in five separate mining districts in order to make new discoveries and expand silver resources."

"At Guanacevi, our focus last year moved north into the San Pedro area, where we received encouraging sample and drill results from a number of recently discovered mineralized zones on historic mine properties. Two exciting new finds, Epsilon and La Blanca, are in the vicinity of historic high grade silver mines along the western side of San Pedro, and two more, San Joachin and Santa Isabel, lie along strike to the north of historic high grade silver mines that occupy the east-bounding faults of the Guanacevi horst block (Endeavour's Santa Cruz, Porvenir Norte, Porvenir Dos and Porvenir Cuatro mines are all located along the west-bounding fault of the Guanacevi horst block)."

"At Guanajuato, we enjoyed significant exploration success in 2010 extending high grade silver-gold mineralization within the Lucero vein for more than 800 meters along strike and more importantly, Endeavour discovered three new mineralized veins parallel to and in the footwall of Lucero, the Karina, Fernanda and Daniela veins. Two drill rigs are working full time to extend these mineralized zones and several compelling new vein targets will also be drilled this year. As a result, Endeavour has commenced a major expansion of the Guanajuato plant to 1000 tonnes per day in the 3^rd Quarter, 2011."

Guanacevi District

Endeavour currently holds 100% interests in 1,072 hectares (2,649 acres) within the historic silver district of Guanacevi which produced over 450 million ounces (oz) of silver according to SGM, the Mexican Geological Service. Since acquiring Guanacevi in 2004, Endeavour has found five high-grade silver ore-bodies along a five kilometer (3 mile) length of the prolific Santa Cruz silver vein (see Guanacevi maps on website, http://www.edrsilver.com/s/Guanacevi.asp).

In 2010, Endeavour drilled 7,000 meters in 23 holes in the San Pedro area resulting in two exciting new finds, Epsilon and La Blanca. Recent drill results not previously announced include 3,319 grams per tonne (gpt) silver and 7.1 gpt gold over a 2.0 meter (m) true width in the Epsilon area (hole EPS1-2), and 3,000 gpt silver and 7.7 gpt gold over a 2.1 m true width in the La Blanca area (hole BC-03).

Endeavour continued to expand its land position at Guanacevi in 2010 with the addition of the 3 properties totaling 25 hectares. Many of the old silver mining properties in Guanacevi had histories of small high grade mine production but very few of them were ever systematically explored and drilled.

Previously unreleased highlights of the 2010 drilling programs at Guanacevi were as follows:

Guanajuato District

Endeavour currently holds 100% interests in 2,314 hectares (5,719 acres) within the historic silver district of Guanajuato which produced over 1.2 billion oz silver according to the SGM. Since acquiring Guanajuato in 2007, Endeavour has discovered three high-grade silver-gold ore-bodies, one along the Veta Madre ore-bearing structure northwest of the Cebada mine and two along the La Luz mineralized veins southeast of the Lucero/Bolanitos mine (see Guanajuato maps on website, http://www.edrsilver.com/s/BolanitosMine.asp).

In 2010, Endeavour drilled 18,000 meters in 61 holes in the Lucero area resulting in three exciting new finds, Karina, Fernanda and Daniela. Recent drill results not previously announced include 158 gpt silver and 6.7 gpt gold over an 8.1 m true width in the Daniela vein (hole KA-27), and 367 gpt silver and 1.9 gpt gold over a 1.8 m true width in the Karina vein (hole KA-29).

Like Guanacevi, Endeavour continued to expand its land position at Guanajuato in 2010 with the addition of the 4 properties totaling 243 hectares. Many of the old silver mining properties in Guanajuato also had histories of small high grade mine production but few of them were systematically explored and drilled.

Parral and Arroyo Seco Properties

In 2010, Endeavour drilled 10,000 meters in 34 holes at the San Juanico property in order to extend the known silver-gold-lead-zinc mineralization on Endeavour's adjacent El Cometa property. Both properties are located within the historic silver district of Parral, Chihuahua, which produced more than 250 million oz silver according to the SGM.

As of March 2009, Endeavour reported an NI 43-101 indicated resource at Cometa of 1.5 million oz silver and inferred resources totaling 1.0 million oz plus significant gold, lead and zinc resources (see Parral maps on website, http://www.edrsilver.com/s/ParralMine.asp). An updated combined resource estimate is anticipated for El Cometa and San Juanico shortly.

Recent drill results not previously announced include 52 gpt silver, 0.7 gpt gold, 4.2% lead and 1.9% zinc over an 4.8 m true width in the Cometa vein (hole SJ0-2), and 267 gpt silver, 1.2 gpt gold, 0.4% lead and 0.4% zinc over a 2.0 m true width also in the Cometa vein (hole SJ1-1). Once the resource estimate is completed, management will review the economic mining potential of the Parral project.

An additional 1200 meters of drilling in 12 holes was carried out at Endeavour's 1,215 hectare (3,002 acre) Arroyo Seco project in Michoacan to try and extend the previously discovered manto-style silver-lead-zinc mineralization along strike and down dip. 

Recent drill results not previously announced include 864 gpt silver and 0.82% lead over an 1.1 m true width in hole AS-14, and 311 gpt silver and 0.94% copper over a 2.0 m true width in hole AS-13. Management has decided to seek a partner or buyer for the Arroyo Seco properties as they do not have sufficient silver potential to be of interest to Endeavour.

2011 Exploration Plans

In 2011, Endeavour plans an aggressive $9.2 million, 47,000 meter, 175-hole exploration drill program to test multiple exploration targets within three of the mining districts where Endeavour is currently active in Mexico plus any new targets within new districts the Company may acquire during the year.

The first priorities will be to follow up the new discoveries made near Endeavour's two mining operations at Guanacevi and Guanajuato as highlighted above and to test several new prospective targets within those two districts. Management is confident that the potential to discover and develop new silver-gold resources at both Guanacevi and Guanajuato remains high.

Endeavour will also commence surface exploration drilling on the San Sebastian properties acquired last year in Jalisco state, Mexico. Surface sampling has identified numerous high-grade silver and gold mineralized zones at San Sebastian that will be tested in 2011.

Significant sample results are as follows:
