Endeavour Silver Reports Higher Earnings, EBITDA, Revenues in Q1, 2010; Silver Production Up 34%, Cash Costs Down 15% Compared to Q1, 2009

Vancouver, Canada - May 10, 2010 - Endeavour Silver Corp. (TSX: EDR, NYSE-Amex: EXK, DB-Frankfurt: EJD) announced today its financial and operating results and unaudited financial statements for the First Quarter, 2010. Endeavour owns and operates two high-grade, underground, silver-gold mines in Mexico, the Guanacevi Mines in Durango State and the Guanajuato Mines in Guanajuato State.

The financial results are expressed in US dollars ("US$") and are based on Canadian generally accepted accounting practices (Canadian "GAAP"). Shareholders are referred to the Company's website for more details: First Quarter, 2010 Financial Statements – /about_us/financials/ and Management Discussion and Analysis ("MD&A") – /about_us/mda/.

First Quarter 2010 Highlights (Compared to Q1, 2009)

  • Silver production climbed 34% to 766,210 ounces (oz)  
  • Gold production jumped 62% to 3,775 oz  
  • Silver equivalent production rose 31% to 1,011,569 oz (65:1 silver: gold ratio, no base metals)  
  • Cash costs fell 18% to $6.39 per oz silver produced (net of gold credits)  
  • Sales revenues increased 115% to $18.2 million  
  • Mine operating cash-flow escalated 249% to $9.1 million  
  • EBITDA was up 1192% to $7.1 million  
  • Net earnings improved from a loss of $1.7 million to earnings of $1.7 million ($0.03 per share)

Bradford Cooke, Chairman and CEO, commented, "Endeavour posted yet another strong quarter of rising silver and gold production and falling cash costs in Q1, 2010. Thanks to our increased production, lower costs and higher metal prices, our revenues, cash-flow, EBITDA and earnings were all up sharply, adding $3.4 million to our working capital during the quarter. From both the operating and financial viewpoints, the Company has never been in better shape."

"We are now into the heart of our capital expansion and exploration programs for the year so silver production will likely remain flat and earnings should dip in the Second Quarter. However, once the new Porvenir Cuatro mine at Guanacevi and the Lucero South/Bolanitos South mine expansions at Guanajuato come into production, silver production, cash costs and earnings should once again resume their positive trends."

"In addition to the organic growth of our two mining operations, management has been focused this year on generating new opportunities for growth through the acquisition of exciting new exploration projects. We are currently drilling the San Juanico property in Parral, Chihuahua targeting a simple extension of the 1.5 million tonnes of Ag-Au-Pb-Zn mineralization already drilled out on our Cometa property next door." 
"Mapping and sampling programs are now underway on the recently acquired, district-scale San Sebastian project in Jalisco in order to prioritize targets for drilling later this year. Last but not least, we are working on a number of prospective new property acquisitions, some of which have substantial bulk tonnage open pit silver-gold potential. All in all, Endeavour is enjoying a very good start to the year."

Financial Results (see Consolidated Statement of Operations)

Sales revenues increased 115% to $18.2 million in Q1, 2010 (Q1, 2009 - $8.5 million) thanks to sharply higher mineral production and metal prices. The Company sold 787,651 silver oz and 4,454 gold oz at average realized prices of $16.93 per oz and $1,105 per oz respectively. Costs of Sales were up 56% to $9.2 million (Q1, 2009 - $5.9 million) primarily due to higher production. 

Mine Operating Cash Flows increased 248% to $9.1 million (Q1, 2009 - $2.6 million); and Mine Operating Earnings rose to $5.8 million (Q1, 2009 - $0.3 million). The Company realized a positive Operating Income of $2.7 million (Q1, 2009 - Loss of $1.2 million), primarily due to higher Mine Operating Earnings. Income Before Taxes was $3.3 million (Q1, 2009 - Loss of $1.9 million). The Company incurred an Income Tax Expense of $1.6 million (Q1, 2009 - Recovery of $0.1 million) for Net Earnings of $1.7 million ($0.03 per share) for the period. 

Cash Operating Costs declined 15% to $6.39 per oz silver produced in Q1, 2010 (Q1, 2009 - $7.56 per oz) thanks to higher plant throughputs at Guanacevi, higher gold production and gold prices, partially offset by lower gold recoveries at both Guanacevi and Guanajuato and the appreciation of the Mexican peso. Endeavour reports its cash operating costs according to the Gold Institute cash cost reporting guidelines so they include offsite costs such as transportation, smelting and refining costs, net of by-product credits.

The Company made capital investments totalling $6.0 million in property, plant and equipment during the First Quarter, 2010. The main focus of the capital programs was the continued development of the Santa Cruz access ramp, the development of the Porvenir Cuatro access ramp and the expansion of the crushing circuit at Guanacevi. At Guanajuato, mine development continued on the South extensions of the Lucero and Bolanitos veins. 

At March 31, 2010, the Company held cash and cash equivalents of $23.5 million and working capital totalled $42.2 million, up from $38.8 million at the end of 2009. 

Operating Results (see Consolidated Table of Operations)

Silver production climbed 34% to 766,210 oz and gold production jumped 62% to 3,775 oz in Q1, 2010 compared to Q1, 2009 thanks to higher plant throughput at both Guanacevi and Guanajuato, partially offset by slightly lower gold recoveries. As a result, silver and equivalent production rose 31% to 1,011,569 oz (65:1 silver: gold ratio, no base metals) compared to Q1, 2009.

Plant throughputs in Q1, 2010 totalled 112,963 tonnes, up 32% compared to Q1, 2009 due to the benefits of the 2009 mine development program at both operations and the 20% plant expansion at Guanajuato. Guanacevi averaged 772 tonnes per day (tpd) and Guanajuato averaged 557 tpd (based on a 6 day work week). Consolidated silver grades averaged 270 grams per tonne (gpt) silver (8.6 oz per ton), comparable to Q1, 2009 but gold grades averaged 1.34 gpt gold (0.04 oz per ton), some 31% higher than Q1, 2009 as a result of higher gold grades at both Guanacevi and Guanajuato and higher plant throughput at Guanajuato. 

Second Quarter 2010 Outlook

Similar to our 2009 plan, management anticipates silver production in Q2, 2010 will be comparable to Q1, 2010. We expect cash costs to resume their decline thanks to anticipated higher gold production and prices. EBITDA and net earnings will also likely decline as exploration spending escalates this quarter (Endeavour expenses its exploration costs on exploration projects). However, silver production is scheduled to increase and cash costs are expected to decrease in Q3 and Q4 as the new ore-bodies under development during the first half of the year enter into production in the second half. 

The 2010 Guanacevi plant upgrade and expansion program is well underway with the installation of a new crushing circuit and the near completion of the 5 year tailings expansion. We are well into our final year of major capital investments in order to unfold the full production capacities at Guanacevi and Guanajuato and the capital expansion programs are currently on time and within budget. 

Some of the healthy cash-flow from operations will once again be put to good use funding our aggressive 2010 exploration programs. Endeavour is focused on following up on our recent new discoveries in both districts, testing several new prospective targets within these two districts, and exploring newly acquired, district-scale silver-gold properties elsewhere in Mexico.

Endeavour Silver Corp. is a small-cap silver mining company focused on the growth of its silver production, reserves and resources in Mexico. Since start-up in 2004, Endeavour has posted five consecutive years of aggressive silver production, reserve and resource growth. The organic expansion programs now underway at Endeavour's two operating silver mines in Mexico combined with its strategic acquisition and exploration programs should help Endeavour achieve its goal to become the next premier mid-tier silver mining company.
