Endeavour Silver Reports Record Production in First Quarter, 2012; Produces 1,072,491 Oz Silver (Up 19%) and 6,321 Oz Gold (Up 26%)

Final NI 43-101 Reserve and Resource Report Results in Minor Adjustments to Reserves and Resources


VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 11, 2012) - Endeavour Silver Corp. (TSX:EDR)(NYSE:EXK)(FRANKFURT:EJD) announced today that the Company set new records for silver and gold production in the First Quarter, 2012 from the Company's two operating silver mines in Mexico, the Guanacevi Mine in Durango State and the Guanajuato Mine in Guanajuato State.

Silver production was up 19% to 1,072,491 ounces (oz) and gold production was up 26% to 6,321 oz compared to the First Quarter 2011. Revenues were up 39% to US$49.0 million thanks to both the higher metal production and higher realized gold prices.

Production Highlights of First Quarter 2012 (Compared to First Quarter 2011)

  • Silver production increased 19% to 1,072,491 oz
  • Gold production rose 26% to 6,321 oz
  • Silver and equivalents production escalated 21% to 1.39 million oz (at a 50:1 silver: gold ratio)
  • Revenues jumped 39% to $49.0 million on 1,100,000 silver oz sold and 7,496 gold oz sold
  • Realized silver price fell less than 1% to $33.10 per oz sold (1.4% above average price for Q1/12)
  • Realized gold price rose 20% to $1,686 per oz sold (equal to average spot price for Q1/12)
  • Metal held in inventory at quarter-end included 925,100 oz silver and 3,927 oz gold

Note: In January and February, 2012, gold and silver prices enjoyed a significant rebound from their lows in December, 2011. Endeavour therefore elected to sell most of the precious metal inventory it accumulated in Q4, 2011 in order to capture the higher gold and silver prices. However, gold and silver prices corrected sharply once again in March 2012 so Endeavour management once again chose to accumulate its precious metal production in Q1, 2012 rather than sell at depressed prices. Management plans to monitor precious metal prices closely and sell some (or all) of the silver and gold inventory at appropriately higher metal prices, or if the need arises for more cash.

Godfrey Walton, President and COO, stated, "Endeavour's two mining operations have enjoyed a good start to 2012 with record silver and gold production in the First Quarter. As a result, the Company is well on the way to achieving its 2012 production guidance of 4.3 million oz silver and 26,000 oz gold. The 2012 organic expansion programs at both mines are now underway with plant throughputs expected to increase 60% by year-end at Guanajuato and 20% by mid-year at Guanacevi."

"At the end of Q1, 2012, the new 115 kva state power line into Guanacevi was connected and energized to the mine and plant. As a result, the Company should enjoy some reduction in operating costs as the electrical generators currently being leased will no longer be needed, and there should be far fewer electrical brown-outs and related pump failures at the mines. The new dry stack tailings facility will also be connected and commissioned this month thanks to the new power supply."

"At Guanajuato, the Lucero South ramp connected with the Lucero Main mine workings during the First Quarter, which should facilitate accelerated mine development and production from the Lucero vein going forward. Mine development continues to open up the Daniela and Karina veins for increasing production throughout the year in order to fill the newly expanded plant."

Final NI 43-101 Reserve and Resource Report

Endeavour has received its final NI 43-101 reserve and resource report to December 31, 2011 and filed it on SEDAR. Some final adjustments were made to the reserve and resource estimates at Guanajuato by the report authors from Micon International Limited.

The net effect is that the proven reserves at Guanajuato were reduced by 25,700 oz silver and 100 oz gold, the indicated resources at Guanajuato were expanded by 3,026,200 oz silver and 24,200 oz gold, and the inferred resources at Guanajuato were expanded by 192,900 oz silver and 3,900 oz gold. The revised final tables of reserves and resources are appended below.
