Endeavour Silver Acquires Option to Purchase San Sebastián Silver-Gold Properties in Jalisco State, Mexico

Vancouver, Canada -- February 9, 2010 - Endeavour Silver Corp. (TSX: EDR, TSX: EDR.WT, NYSE Amex: EXK, DBFrankfurt: EJD) announces that it has acquired an option to purchase the San Sebastián silver-gold properties in Jalisco State, Mexico from IMMSA (Grupo Mexico), one of the largest mining companies in Mexico. 

San Sebastián del Oeste is an historic silver and gold mining district located in south-western Jalisco State, approximately 155 kilometres (km) southwest of Guadalajara and 40 km northeast of Puerto Vallarta, accessible by paved and gravel roads. One small, high grade, underground silver-gold mine, Santa Quiteria (75 tonnes per day), continues to operate in the district. The San Sebastián properties being acquired by Endeavour surround the Santa Quiteria mine and represent a new, district-scale, silver-gold exploration opportunity for the Company. 

The San Sebastián properties (3,320 hectares) cover a classic, low sulfidation, epithermal vein system in four mineralized vein sub-districts named Los Reyes, Santiago de los Pinos, San Sebastián del Oeste and Real de Oxtotipan. Each sub-district consists of a cluster of quartz (calcite, barite) veins mineralized with sulfide minerals (pyrite, argentite, galena, and sphalerite). Each vein cluster spans about a 3 km by 3 km in area. In total, more than 50 small mines were developed historically within at least 20 separate veins. 

The San Sebastián veins tend to be large and can carry high grade silver-gold mineralized ore-bodies. For example, the La Quiteria vein ranges up to 15 m thick, and the Santa Quiteria mine averages about 280 grams per tonne (gpt) silver and 0.5 gpt gold over a 3 m to 4 m width. This high grade mineralized zone appears to extend into the San Sebastián properties both along strike and immediately down dip.

Although the San Sebastián silver mines were first discovered in 1542, and there were several periods of small-scale mining over the last 450 years, the only significant modern exploration in the district was carried out by IMMSA in the late 1980's and early 1990's. IMMSA systematically assayed more than 200 rock samples from many of the old mines, the highlights of which are shown in the following table: 

IMMSA Sampling Highlights

Mine Width (m) Silver (gpt) Gold (gpt)
La Quiteria Random grabs 10 – 9,649 0.01 – 11.92
San Agustín Random grabs 24 – 1,770 0.01 – 3.12
El Tajo Random grabs 74 – 933 0.06 – 1.62
Terronera Random grabs 16 – 397 0.01 – 4.67
El Padre Random grabs 15 – 571 0.01 – 0.44
El Fraile 1.5 363 1.44
Demócrata 1.0 814 0.98
La Luz 1.3 325 28.0
Los Reyes 1.0 1,485 3.35
San Antonio 1.25 823 0

IMMSA also drilled 17 widely spaced diamond drill holes, mostly on the Terronera vein. The drilling succeeded in intersecting widespread silver-gold mineralization ranging from 0 to 1 gram per tonne (gpt) gold and from 50 to 150 gpt silver over 2 to 6 meter (m) widths. Since the known high-grade silver-gold ore-body at the Santa Quiteria mine is restricted to a discrete, plunging ore-body measuring about 200-250 m long by 200-250 m deep by 2.5-5.0 m thick, Endeavour exploration personnel are of the opinion that substantial potential exists to find additional high grade mineralized zones within the several dozen kilometers of known veins on the San Sebastián properties. The vast majority of these veins have never been drilled.

Endeavour geologists collected 17 rock samples from some of the historic mines on the San Sebastián properties. Sampling highlights are shown in the following table:

Endeavour Sampling Highlights

Sample (m) Width (m) Silver (gpt) Gold (gpt)
QT-1 Selected grabs - waste dump 279 0.7
QT-3 Selected grabs - high grade 6,843 36.1
QT-5 Random grabs - conveyor belt 430 1.5
QT-6 Selected grabs - high grade 11,824 40.3
VR-1 Selected grabs - waste dump 419 1.17
VLR-1 Selected grabs - waste dump 261 0.48
VL-1 2.5m x 2.5m grab – waste dump 320 3.36

Endeavour can acquire a 100% interest in the San Sebastián properties from IMMSA by making cash payments totaling US$2.75 million and spending US$2.0 million on exploration over a three year period. IMMSA will retain a 2% NSR royalty on mineral production from the properties. Endeavour was introduced to the San Sebastián opportunity by Candiani Mining, a mineral consulting company based in Mexico City. 

Bradford Cooke, Chairman and CEO of Endeavour, commented, "We are pleased to conclude this San Sebastián transaction, as it represents an attractive first step in our acquisition strategy for 2010. We plan to expand our silver project portfolio by continuing to consolidate our land-holdings in Guanaceví and Guanajuato; by acquiring one or two new district-scale exploration opportunities like San Sebastián; and by continuing to evaluate both resource development projects, as well as operating silver mines. Our exploration team plans to commence exploration field work at San Sebastián shortly so that new high grade silver-gold targets can be readied for drilling later this year."

Barry Devlin, M.Sc., P. Geo., the Vice President of Exploration for Endeavour, is the Qualified Person who reviewed this news release and supervised the sampling program at the San Sebastián Project. All samples were shipped to Inspectorate Labs in Durango, Mexico, where they are dried, crushed, split and 50 gram pulp samples are prepared for analysis. Gold and silver are determined by fire assay with a gravimetric finish.

Endeavour Silver Corp is a small-cap silver mining company focused on the growth of its silver production, reserves and resources in Mexico. Since start-up in 2004, Endeavour has posted five consecutive years of growing silver production and resources. The organic expansion programs now underway at Endeavour's two operating silver mines in Mexico combined with its strategic acquisition program should help propel Endeavour to become the next premier mid-tier primary silver producer.
