Endeavour Discovers New High Grade Lead- Zinc-Copper-Gold-Silver Mineralized Vein Zone at Parral Project, Chihuahua State, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 12, 2007) - Endeavour Silver Corp. (TSX:EDR)(AMEX:EXK)(DBFrankfurt:EJD) announces that it has discovered a new high grade lead-zinc-copper-gold-silver mineralized vein zone on the El Cometa property, part of the Parral Project located in Chihuahua State, Mexico.

To date, Endeavour has drilled 5,200 m in 16 holes to outline the new mineralized zone in the El Cometa vein (part of the Esmeralda vein system) over a 400 m length and to depths of 350 m, ranging from 0.5 to 5.0 m in true thickness. The Esmeralda mine, located 2 km south of El Cometa, produced 1 million tonnes of ore grading 6% Pb-Zn, 100 gpt Ag and 0.5 gpt Au over a 1.2 km length to depths of 650 m and widths of 1 to 10 m.

Drilling highlights include high grade intercepts such as 8.60% Pb, 2.69% Zn, and 1.42 gpt gold and 74 gpt Ag over 5.75 m in hole CM15-2; 2.26% Pb, 4.27% Zn, 37.40 gpt Au and 36 gpt Ag over 0.95 m in hole CM18-1; and 5.81% Pb, 3.24% Zn, 0.99 gpt Au and 137 gpt Ag over 3.85 m in hole CM18-2.

Half of the drill holes also intersected a hangingwall splay of the Cometa vein, called Mexicana. Drill intercepts in the Mexicana vein include 3.05% Pb, 3.06% Zn, 2.98 gpt Au and 32 gpt Ag over 12.0 m; 3.12% Pb, 3.06% Zn, 0.93 gpt Au and 29 gpt Ag over 10.8 m; and 5.24% Pb, 10.26% Zn, 1.40 gpt Au and 51 gpt Ag over 3.85 m, all within drill hole CM17-1 (true widths are significantly less than the reported core lengths in the Mexicana splay).

The El Cometa drill results are summarized in the following table and are also plotted on a longitudinal section on the Endeavour website: http://www.edrsilver.com/i/pdf/2007-06-12_NRM.pdf

A Phase 2, 3,000 m, 8 hole drill program is now underway at El Cometa in order to fill in the gaps in the drill grid so that an initial resource estimate can be made in Q3, 2007. Endeavour is also drilling several other target areas within the Parral Project, as well as continuing to build its land position through additional property acquisitions.

Bradford Cooke, Chairman and CEO, commented, "Our aggressive acquisition and exploration programs at the Parral Project are starting to bear fruit. El Cometa is the first new discovery in the Parral district in many years. Although dominantly lead-zinc rich, the discovery at El Cometa does carry silver-gold rich zones and the high grade, polymetallic mineralization is typically found over decent vein widths. Once we have established an initial resource estimate, management will review alternatives for maximizing the value of the El Cometa discovery."

Godfrey Walton, M.Sc., P.Geo. and Barry Devlin, M.Sc., P.Geo. are the Qualified Persons who reviewed this news release and supervised the surface drilling and sampling programs at the Parral Project. A Quality Control sampling program of blanks and duplicates has been instituted to monitor the integrity of all assay results. All core samples are split at the Parral field office and shipped to SGS assay lab in Durango where they are dried, crushed, split and 30 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. (TSX:EDR)(TSX:EDR.WT)(AMEX:EXK)(DBFrankfurt:EJD) is an emerging mid-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 silver mines, Guanacevi in Durango and Bolanitos in Guanajuato, coupled with the Company's aggressive acquisition and exploration programs in Mexico, should enable Endeavour to join the ranks of top primary silver producers worldwide.
