Endeavour Silver Drilling Intersects Thicker, Deeper Extension of Santa Cruz Silver Zone at Guanacevi; Infill Drilling Defines Poly-Metallic Mineralization in Cometa Zone at Parral

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 12, 2008) - Endeavour Silver Corp. (TSX:EDR)(AMEX:EXK)(DBFrankfurt:EJD) announces additional positive drill results from exploration programs on two of the Company's silver mine properties in Mexico.

At the Company's operating Guanacevi silver mine in Durango, drilling below the current resource has intersected a thick, poly-metallic extension of the Santa Cruz vein below the historic Santa Cruz mine. At Endeavour's Parral exploration program in Chihuahua, infill drilling has better defined the poly-metallic mineralization discovered last year in the El Cometa vein system on the El Cometa property.

Results were as follows:

Bradford Cooke, Chairman and CEO, stated, "We made good progress advancing exploration at both the Santa Cruz and El Cometa properties in Q1, 2008, as shown by these latest positive drill results. The Santa Cruz ramp is being developed now to provide access for production next year and facilitate the next phase of production growth at Guanacevi. At Parral, we plan to continue our exploration efforts to expand resources in other areas of the district in order to achieve "critical mass" for a mining operation."

Three drill holes at Santa Cruz (see longitudinal section on website: http://www.edrsilver.com/i/maps/2008-06-11_NRM1.gif) have extended the mineralized zone an additional 100 m down-dip to the north-east, where it remains open for expansion. They also mark the first significant occurrence of potentially economic base metals at Santa Cruz, accompanied by lower precious metal grades typical of the deeper parts of the classic, low sulpidation epithermal vein systems found in Mexico. Discovery of the base metal zone is timely due to the fact they can be added to a new resource estimate to be prepared later this year and they can be recovered in the Guanacevi plant flotation circuit, which is scheduled to be re-commissioned in Q3 and expanded in Q4, 2008.

Santa Cruz was a historic silver mine discovered by the Spanish in the late 1500's and mined again by Industrias Penoles in the 1900's. Penoles sank an inclined 270 m deep shaft and developed the mine down 13 levels. Endeavour commenced exploration drilling below the deepest mine level 13 in 2005 in order to search for extensions of the Santa Cruz mineralization.

The Santa Cruz mineralized zone was recently estimated (see news release March 3, 2008: www.edrsilver.com/s/NewsReleases.asp?ReportID=289344&_Type=News&_Title=Endeavour-Announces-NI-43-101-ReserveResource-Update-ProvenProbable-Reserve...) (Due to the length of this URL, it may be necessary to copy and paste this hyperlink into your internet browser's URL address field) to contain about 6.9 million oz silver within an indicated resource of 330,000 tonnes grading 391 gpt silver and 0.69 gpt gold, and an inferred resource of 220,000 tonnes grading 379 gpt silver and 0.62 gpt gold, as defined by 43 drill holes to date.

Last year, Endeavour commenced driving an 820 m ramp from the nearby operating Porvenir mine towards the Santa Cruz resource area in order to bring Santa Cruz into production in 2009. To date, 530 m of ramp have been completed and an additional 290 m is planned for this year, so that mine development can commence in Q1, 2009 and production can begin in Q3, 2009.

Seven drill holes at El Cometa (see longitudinal section on website: http://www.edrsilver.com/i/maps/2008-06-11_NRM2.gif) have better defined this mineralized zone for mine planning and economic analysis. Each of these holes intersected poly-metallic mineralization with average grades higher than Endeavour's estimated US$50 per tonne NSR cut-off grade assuming metal prices of USD$12 per ounce silver, USD$600 per ounce gold, USD$3.00 per pound copper, USD$0.60 per pound lead and USD$1.50 per pound zinc.

El Cometa was a historic silver mine discovered and mined in the 1900's. The mine was developed on 3 levels by a 75 m deep shaft. Endeavour acquired the property in 2006 and commenced drilling to test for poly-metallic mineralized zones similar to the La Esmeralda mine located 2 km to the south along the same vein system. Esmeralda is estimated to have produced 4 million tonnes of ore grading 6% combined Pb-Zn, 100 gpt Ag and 0.5 gpt Au on 10 mine levels to 600 m in depth.

The El Cometa mineralized zone was recently estimated (see news release dated March 3, 2008: www.edrsilver.com/s/NewsReleases.asp?ReportID=289344&_Type=News&_Title=Endeavour-Announces-NI-43-101-ReserveResource-Update-ProvenProbable-Reserve...) (Due to the length of this URL, it may be necessary to copy and paste this hyperlink into your internet browser's URL address field) to contain about 2.2 million oz silver within an indicated resource of 600,000 tonnes grading 39 gpt Ag, 1.0 pgt Au, 2.7% Pb and 3.0% Zn, and an inferred resource of 1,150,000 tonnes grading 39 gpt Ag, 1.0 gpt Au, 2.4% Pb, and 2.5% Zn, as defined by 32 drill holes to date.

The Company plans to continue exploration in the Parral district until sufficient resources have been outlined to support the purchase or construction of central milling facility.

Endeavour currently has four drill rigs working in Mexico in order to expand the Company's resources and the mine-lives of the Guanacevi and Guanajuato mine projects. Additional drilling updates are anticipated shortly once the assay labs complete their current backlog of drill core samples.

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 also announces that in accordance with the Company's registered stock option plan, a total of 1,400,000 incentive stock options have been set for employees, officers and directors, exercisable at $3.05 for up to a five year period. These options have vesting requirements over a two year period in order to help the Company retain its key employees.

Endeavour Silver Corp. (TSX:EDR)(AMEX:EXK)(DBFrankfurt:EJD) 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.
