Endeavour Silver Drilling Intersects Three Gold-Silver Mineralized Zones near Historic Workings at the Bolañitos Mine in Guanajuato State, Mexico

Vancouver, Canada – July 22, 2013 - Endeavour Silver Corp. (NYSE: EXK, TSX: EDR,) announces that exploration drilling at the Company’s Bolañitos mine in Guanajuato State, Mexico has intersected three high grade, gold-enriched silver mineralized zones near historic mine workings in the Asuncion, La Luz and Plateros areas of the La Luz vein system.

Surface and underground drilling highlights include:

• 122 grams per tonne (gpt) silver and 3.32 gpt gold over 3.43 metres (m) true width, or 9.4 ounces per ton (opT) silver equivalents over 11.3 feet (ft), in hole ASU12-12, including 392 gpt silver and 15.1 gpt gold over 0.48 m true width, or 37.8 opT silver equivalents over 1.6 ft, in Asuncion area
• 124 gpt silver and 3.45 gpt gold over 4.4 m true width, or 9.7 opT silver equivalents over 14.4 ft, in hole PL6-1, including 224 gpt silver and 7.46 gpt gold over 0.54 m true width, or 19.6 opT silver equivalents over 1.8 ft, in the Plateros vein
• 120 gpt silver and 2.21 gpt gold over 7.9 m true width, or 7.4 opT silver equivalents over 25.8 ft, in hole LZ18-1, including 398 gpt silver and 3.28 gpt gold over 0.7 m true width, or 17.3 opT silver equivalents over 2.3 ft in the La Luz vein

Each of the three new mineralized zones is about 200 m long by 100 m deep, and two are readily accessible for mining from nearby historic workings. The following tables highlight the results of 17 holes drilled in the Plateros, La Luz and Asuncion areas in 2013. Click here to view the Plateros and Asuncion/La Luz Longitudinal Sections. Silver equivalents are calculated at a ratio of 60: 1 silver: gold.

Luis Castro, Vice President of Exploration, commented, “With our refined understanding of the local geological controls on mineralization at Bolañitos, our surface and underground exploration teams are now finding gold-rich extensions of silver mineralized zones in the vicinity of historic mine workings. These areas will be included in our year-end resource estimate and mine plan. In fact, the mine operations team has already gained access to and commenced production from the Asuncion area.”

Godfrey Walton, M.Sc., P.Geo. President and COO, is the Qualified Person who reviewed and approved this news release and supervised the drilling programs at Bolañitos. A Quality Control sampling program of reference standards, blanks and duplicates has been instituted to monitor the integrity of all assay results. All samples were split at the Bolañitos field office 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 other elements are determined by AA.
