Endeavour Drilling Returns Best Hole Yet at Guanacevi Mines Project, Durango, Mexico

June 27, 2006, - Vancouver, Canada - Endeavour Silver Corp. (EDR: TSX, EDRGF: PNK, and EJD: FSE) announces that drilling at the Guanacevi Mines Project in Durango, Mexico has returned the best hole yet. Drill hole DSC-16 intersected 673 gpt silver and 1.38 gpt gold over 21.5 meters (21.8 oz per ton silver equivalent over 70.5 feet) in the Santa Cruz Zone.

In addition, significant lead-zinc mineralization was also intersected in the recent drilling, associated with some (but not all) of the silver mineralized zones. All five of the drill holes reported herein intersected multiple zones of either very high grade silver over mineable widths, or very large vein thicknesses of moderate grade silver-gold-lead zinc mineralization, or both.

Other drilling highlights include 4402 gpt silver and 4.46 gpt gold over 1.10 m (135.5 oz per ton silver equivalent over 3.6 ft) and 765 gpt silver, 2.90 gpt gold, 3.03% lead and 5.72% zinc over 4.30 m in hole DSC2-16, 3884 gpt silver and 4.87 gpt gold over 0.75 m (121.0 oz per ton silver equivalent over 2.5 ft) in hole DSC2-13 and 117 gpt silver, 0.23 gpt gold. 2.00% lead and 3.63% zinc over 12.8 m in hole DSC2-15. Significant drill results are as follows:

Drill hole DSC2-14 does not appear to have intersected the Santa Cruz vein nor any significant silver mineralization, possibly due to an oblique fault pulling apart the vein in this area. However, the main Santa Cruz Zone still appears to be open to the northwest and at depth. (See Santa Cruz longitudinal section on the Endeavour website www.edrsilver.com)

Because the underground drill rig has reached the limits of what it can drill along the Santa Cruz vein from crosscut #2 on level #13, drilling has now moved to the La Prieta zone at the south end of the Santa Cruz property. Crosscut #2 is now being extended so that future drilling can continue testing the Santa Cruz Zone towards the northwest and at depth.

Bradford Cooke, Chairman and CEO, stated, "Our drilling results below mine level #13 in the Santa Cruz Zone just keep on getting better and better. These latest holes are located up to 450 m below surface and we still have not found the depth extent of the high-grade, silver-gold mineralization. Given the significant lead-zinc mineralization in the latest drill holes, Endeavour will evaluate the potential for the Santa Cruz ores to be processed through the plant by either flotation or leaching in order to maximize the recoverable metal values. "

Godfrey Walton, M.Sc., P.Geo., is the Qualified Person supervising the surface and underground drilling and sampling programs at the Guanacevi Mines 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 Guanacevi minesite, assayed at the Guanacevi plant, and rejects, blanks and duplicates are delivered to the BSI Inspectorate sample prep lab in Durango for the preparation of sample pulps. Samples are dried, crushed, split and 30 gram pulp samples are then air freighted to Reno, Nevada for analysis at the BSI Inspectorate laboratory. Gold and silver at both Guanacevi and BSI are determined by fire assay with an atomic absorption (AA) finish.

Endeavour Silver Corp. (EDR: TSX, EDRGF: PNK, and EJD: FSE) is a small cap silver mining company focused on the aggressive growth of its silver production, resources and reserves in Mexico. The expansion program now underway at the high grade Guanacevi Mines Project in Durango, Mexico should propel Endeavour into the ranks of the top five primary silver producers.
