Endeavour Sets New Record For Quarterly Silver Production, Up Sharply In Q3, 2007 To 577,384 oz Silver (676,604 oz Ag Equivalent)

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Oct. 17, 2007) - Endeavour Silver Corp. (TSX:EDR)(TSX:EDR.WT)(AMEX:EXK)(DBFrankfurt:EJD) announced today that its silver production was up sharply in Q3, 2007, to 577,384 oz silver and 1,804 oz gold (676,604 oz Ag equivalent at a 55 silver: 1 gold ratio), setting a new record for quarterly silver production from the Company's two operating mines in Mexico.

Silver production was 34% higher than Q2, 2007 and jumped 74% compared to Q3, 2006. Year to date, silver production from the Guanacevi Mines Project in Durango and the Bolanitos Mines Project in Guanajuato totals 1,498,618oz and 4,305 oz gold (1,735,393 oz Ag equivalent), well on track towards meeting the Company's revised production forecast of 2 million oz silver in 2007.

Bradford Cooke, Chairman and CEO, commented, "Endeavour enjoyed another record quarter of silver production in Q3, 2007. Notwithstanding certain issues and delays experienced by the Guanacevi plant expansion and Bolanitos mine development projects, the Company once again added to its track record for strong production growth quarter-on-quarter. With the recent appointment of our new Vice President, Mexico Operations, David Howe, we are confident Endeavour will continue to grow production at a steady pace and focus on improving its operating performance."

A total of 94,469 tonnes of ore were processed by the two plants in Q3, 2007 at average grades of 281 gpt silver and 0.80 gpt gold (325 gpt Ag equivalent), and average recoveries of 67.8% for silver and 74.4% for gold (see Comparative Table of Mine Operations below).

Comparing the 3rd quarter 2007 to the 2nd quarter 2007, plant throughputs were both up sharply due to the increased mine output at Bolanitos and the expanded capacity at the Guanacevi plant; silver and gold grades were down due to higher than anticipated mine dilution and the processing of lower grade stockpiles at Guanacevi; silver and gold recoveries were also down due to plant inefficiencies during this time of plant improvement projects; and silver and gold production were both significantly higher because of the higher plant throughputs.

After a review of mine operations in August, management initiated new procedures at both mines in order to reduce mine dilution and improve grade control. As a result, ore grades at Bolanitos rose in September and a similar positive impact is anticipated at both Bolanitos and Guanacevi in the current quarter.

In the same way, management's review of plant operations in July and August resulted in a simple change to the flotation circuit at Bolanitos that has already improved recoveries. Metal recoveries at Guanacevi continued to lag in Q3, 2007 but with the new Merrill Crowe circuit now on-line, management anticipates higher metal recoveries in Q4, 2007.

At Guanacevi, the new lined tailings pond came into operation in July and the expanded Merrill Crowe recovery circuit was successfully commissioned at the beginning of October. Other capital improvement projects are expected to the completed by year-end and can be updated as follows:

- New silver dore refinery 70% complete
- New high density tailings thickeners 40% complete
- Expanded agitation leach tanks 20% complete
- Porvenir pump station 80% complete
- Santa Cruz ramp 40% complete

At Bolanitos, the Phase 1 tailings pond expansion was completed in July and Phase 2 is now in planning for next year. Several mine development projects were initiated in Q3, 2007 for completion by year-end and can be updated as follows:

- Cebada level 315 clean-up 100% complete
- Cebada level 515 clean-up 80% complete
- Ascuncion mine dewatering 60% complete

Endeavour plans to release its financial results for the 3rd quarter on November 14th, 2007. Godfrey Walton, M.Sc., P. Geo., is the Qualified Person responsible for reviewing all of the operating data for the Guanacevi and Bolanitos Mines Projects.

Endeavour Silver Corp. (TSX:EDR)(TSX:EDR.WT)(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 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.
