VANCOUVER, British Columbia, July 10, 2018 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. (TSX:EDR) (NYSE:EXK) reports its production results for the Second Quarter, 2018 from the Company’s three silver-gold mines in Mexico: the Guanaceví mine in Durango state and the Bolañitos and El Cubo mines in Guanajuato state.

Silver production in the Second Quarter, 2018 increased 19% to 1,355,895 ounces (oz) compared to 1,143,788 oz silver in Q2, 2017 and gold production rose 5% to 13,674 oz compared to 13,058 oz gold in Q2, 2017, resulting in silver equivalent production of 2.4 million oz using a 75:1 silver-gold ratio.

Silver production was higher in Q2, 2018 compared to Q2, 2017 primarily due to higher mine output and ore grades at El Cubo. The Guanacevi mine continued in recovery mode as production was flat but mine development increased in Q2, 2018.  Gold production in Q2, 2018 compared to Q2, 2017 was higher at El Cubo and Guanacevi and lower at Bolanitos due to variations in gold grades at each mine.

Production Highlights for Second Quarter, 2018 (Compared to Second Quarter, 2017)

  • Silver production increased 19% to 1,355,895 oz
  • Gold production increased 5% to 13,674 oz
  • Silver equivalent production was 2.4 million oz (at a 75:1 silver: gold ratio)
  • Silver oz sold increased 27% to 1,258,617 oz
  • Gold oz sold increased 12% to 13,800 oz
  • Bullion inventory at quarter-end included 176,452 oz silver and 265 oz gold
  • Concentrate inventory at quarter-end included 53,810 oz silver and 827 oz gold

Bradford Cooke, Endeavour CEO, commented, “Our Second Quarter, 2018 production was much improved over Q2, 2017, continuing the trend established in the First Quarter 2018.  As a result, we are on track to meet our guidance of higher production and lower costs in 2018 thanks to improved operating performance at the El Cubo and the development of our fourth mine at El Compas.

“El Cubo is currently performing ahead of plan and Guanacevi is still lagging behind plan but with mine development up in Q2, 2018, and the Milache orebody coming into production, Guanacevi mine output should improve in Q3, 2018.  Our fourth and newest mine at El Compas should also achieve commercial production by the end of July, and be the main driver of increased production in the Second Half of 2018.

“Several catalysts are expected in Q3, 2018 to move our fifth and largest mine project at Terronera towards a development decision.  An optimized pre-feasibility study is forthcoming, the final two government environmental permits (mine dumps and tailings facilities) are anticipated shortly and an initial debt facility to help fund the new Terronera silver-gold mine is currently being prepared.”

Operations Summary for Second Quarter, 2018

At Guanacevi, mine output was lower in Q2, 2018 compared to Q2, 2017 due to restricted ore access related to certain operating issues that slowed mine development in 2017, and the reallocation of mine personnel to implement a productivity optimization program in 2018.  However, ore grades and metal recoveries were both higher in Q2, 2018 due to better dilution control, normal grade variations and lower throughput in the plant.  As a result, silver production was down slightly and gold production was up significantly, resulting in higher silver equivalent production. Management anticipates silver production will improve in Q3, 2018 due to increased mine development in Q2, 2018, completion of the productivity optimization program and commencement of production of development ore from the Milache ore body in Q3, 2018.

At Bolañitos, mine output and gold grades were lower but silver grades were higher in Q2, 2018 compared to Q2, 2017. The grade fluctuations are due to variations of geology and the access within the LL-Asunción vein impacted the mine output.  Silver equivalent production in Q2, 2018 was lower than Q2, 2017 due primarily to the lower gold grades. Gold grades are expected to return to plan during the year.   

At El Cubo, mine output, silver grades and gold grades were all higher, Q2, 2018 compared to Q2, 2017, which resulted in a sharp increase in production in Q2, 2018.  The higher grades are according to plan and expected to continue throughout 2018.

The El Compas mine development project remains on track for commercial production by the end of July. Mining and stockpiling of ore commenced and commissioning of the plant was initiated in Q2, 2018 using low grade ore.  A total of 4,900 tonnes of run-of-mine ore were stockpiled in Q2, 2018 but only 1,023 tonnes were processed to test all the plant circuits as of June 30th.  As expected, plant circuits are being modified, configured and fine-tuned to resolve normal start up issues.  Both mine and plant are now ramping up throughput to achieve commercial production at the PEA target capacity of 250 tonnes per day by the end of July.
