Endeavour Reports Record Quarterly Silver Production, Gross Revenues, Operating Cash Flow, Mine Operating Earnings and Loss for the Period in First Quarter 2006

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - May 18, 2006) - Endeavour Silver Corp. (TSX:EDR)(PINK SHEETS:EDRGF)(FWB:EJD) today reported record quarterly silver production, gross revenues, operating cash flow, mine operating earnings and loss for the period in the First Quarter, 2006. The First Quarter report only reflects consolidation of Endeavour's Mexican subsidiaries operations as of February 1, 2006, after certain option payments were made.

First Quarter financial and operating highlights include: (amounts in financial statements are CA$ but amounts in this news release are US$)

Financial Highlights (February- March Consolidated)

- Average silver price- US$9.69 per oz.

- Record gross revenues- US$2.24 million

- Record operating cash flow- US$875,704

- Record mine operating earnings- US$456,475

- Cash Costs net of gold credit- US$5.47 per oz. silver

- Loss for the period US $1.65 million

- Loss per share US$0.05

- Q1 2006 capital investments- US $2.9 million

- End Q1 2006 cash and equivalents- US $14.8 million

- Consolidated operations for its 51% interest in the Santa Cruz properties and Guanacevi plant on February 1, 2006 (Endeavour controls 100% of project cash flows until its project loans are repaid with 9% interest)

Operating Highlights (January-February-March)

- Record silver production of 300,872 oz from processing of 24,805 dry tonnes grading 479 gpt Ag and 0.95 gpt Au or 15.3 opt Ag equivalent

- Stockpiled 7300 tonnes ore grading 542 gpt Ag and 0.94 gpt Au or 17.2 oz per tonne silver equivalent as the mine out-performed the plant

- Estimated new silver reserves of 3.5 million oz contained in 183,875 tonnes grading 589 gpt Ag and 0.85 gpt Au or 20.3 opt Ag equivalent

- Updated new inferred silver resources (up 112%) of 10.6 million oz contained in 755,476 tonnes grading 439 gpt Ag and 0.88 gpt Au or 15.9 opt Ag equivalent

- Commenced refurbishment of Guanacevi plant which reduced plant availability to 70%

Gross revenues for the First Quarter (only February-March consolidated) were a record US$2.24 million, thanks to increases in both silver production and the silver price. Operating cash flow before depreciation, depletion and amortization was a record US$875,704 and mine operating earnings were US$456,475.

Cash costs net of gold as a credit averaged US$5.47 per oz. silver. These costs were higher than anticipated and silver production was lower than anticipated, due to reduced plant availability, which averaged 70% in Q1, 2006 allowing for repairs and refurbishment. Cash costs were calculated using total plant operating costs plus the mine costs for material processed by the plant, minus the revenues for gold. The Company anticipates that cash costs will drop substantially as production increases through the balance of the year.

Endeavour's core asset, the Guanacevi Mines Project in Durango, Mexico, produced 300,872 oz silver and 605 oz gold, or 331,122 oz silver equivalents (using a 50 Ag: 1 Au ratio) for the three months ended March 31, 2006. This represents a 180% jump over Q4, 2004 (December 2004-Jan-Feb 2005) and a 6% increase over the last three months of 2005.

Total Guanacevi plant throughout was 24,805 dry tonnes (average 279 tpd) grading 479 gpt Ag and 0.95 gpt Au, or 15.3 opt Ag equivalent. Metal recoveries averaged 77.4% for silver and 79.5% for gold. The Porvenir mine provided 88% of the plant throughout, the balance coming from the re-processing of old tailings (8.1%) and the custom milling of sulfide ores from another small mine in the Guanacevi district (4.3%).

Total Porvenir mine output was 32,105 dry tonnes (average 434 tpd) grading 542 gpt Ag and 0.94 gpt Au, or 17.2 opt Ag equiv., of which 7,300 tonnes were stockpiled at the plant for future processing. Endeavour's plans for Q2, 2006 call for the mine to continue out-producing the plant in order to build up the ore stockpiles so that when the new ball mill is operational by the end of June, the plant can then operate at a higher level than the mine to year-end in order to meet the 2006 production target of 2.0 to 2.2 million oz silver.

Bradford Cooke, Chairman and CEO, commented, "Endeavour enjoyed a good start to the year, thanks to increased production and a rising silver price. Silver production should remain relatively flat through the Second Quarter, while the plant refurbishment program is underway. The mounting ore stockpiles from the mine should allow the plant to outperform the mine for the second half of the year. Cash costs were high during Q1 due to the reduced plant availability but these costs should come down substantially in Q3 and Q4 to the forecast average price of approximately US$4.50 per oz.

We continue to expand the three main mineralized zones utilizing four drill rigs and additional drill results will be released monthly. Both the Porvenir Mine and Deep Santa Cruz zones appear to be thickening at depth even through the vertical drill extent now exceeds 400 m."

Capital expenditures during Q1, 2006 totaled $2.9 million, of which 83% was attributed to exploration at the Guanacevi Mines Project. Four drill rigs completed 54 holes totaling 10,460m of drilling in three resource areas, Deep Santa Cruz, Porvenir Mine (North Porvenir and El Porvenir) and Porvenir Dos. An updated, independent review of reserves and resources was completed by Range Consulting Group to the end of the First Quarter as follows:

A safety and environmental program was established at the mine and plant with 1,195 hours of safety training completed in the first quarter of 2006. At the end of 2005, a total of 5,800 square meters was reclaimed with re-contouring of disturbed ground and 4,100 new trees were planted. The company will be planting another 5,000 trees in 2006 in an estimated area of 6,000 square meters so that any disturbed area is reclaimed as soon as possible.
