True widths are 65% to 80% of core lengths. Silver equivalents are based on a 50 silver : 1 gold ratio.

The Deep Santa Cruz Zone is located one kilometer southeast of Endeavour’s new Porvenir Mine along the same Santa Cruz vein and lies below the lowest mine level #13 in the Santa Cruz Mine. It is the deep extension of the historic Santa Cruz ore-body, mined originally by the Spanish over 400 years ago, and drilled by Industrias Penoles in the 1980’s. However, in this area, the Santa Cruz vein has splayed into several parallel veins, each of which can carry economic grades over mineable widths, including one main vein very similar to the one in the Porvenir Mine that appears to thicken with depth.

Endeavour has now completed 24 drill holes using one drill rig from two underground cross-cuts in the Santa Cruz Mine to confirm and extend the Deep Santa Cruz resource area for over 200m below level #13 and 200m along strike, still open along strike and down dip to the northwest (seeDeep Santa Cruz longitudinal section and April 19, 2006 news release on Company Website). An additional 6 holes have been drilled from crosscut #2, sampled and sent out for assays.

Because the Deep Santa Cruz Zone is still open to the northwest, an extension of crosscut #2 will be driven to establish a new drill station to the northwest. Drilling continues on the Guanacevi Mines Project with four drill rigs, one underground in the Deep Santa Cruz Zone and three on surface working near the Porvenir Mine and other prospective zones and targets on the project.

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

ENDEAVOUR SILVER CORP.
