VANCOUVER, British Columbia, April 09, 2018 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. (TSX:EDR) (NYSE:EXK) reports its production results for the First 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 First Quarter, 2018 increased 25% to 1,350,840 ounces (oz) compared to 1,076,974 oz silver in Q1, 2017 and gold production rose 13% to 13,208 oz compared to 11,724 oz gold in Q1, 2017, resulting in silver equivalent production of 2.3 million oz using a 75:1 silver-gold ratio.

Silver production was higher in Q1, 2018 compared to Q1, 2017 due to higher mine output and ore grades at El Cubo and Bolañitos, partly offset by lower mine output at Guanacevi as the mine continues to recover from some operating issues last year. Gold production in Q1, 2018 compared to Q1, 2017 was higher at El Cubo and Guanacevi and lower at Bolañitos due to variations in gold grades at each mine.

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

  • Silver production increased 25% to 1,350,840 oz
  • Gold production increased 13% to 13,208 oz
  • Silver equivalent production was 2.3 million oz (at a 75:1 silver:gold ratio)
  • Silver oz sold increased 14% to 1,406,143 oz
  • Gold oz sold increased 12% to 12,674 oz
  • Bullion inventory at quarter-end included 85,675 oz silver and 302 oz gold
  • Concentrate inventory at quarter-end included 74,359 oz silver and 1,195 oz gold

Bradford Cooke, Endeavour CEO, commented, “Our First Quarter production was much improved over last year.  As a result, we are on track to deliver higher production and lower costs in 2018 thanks to improved operating performance at each of the three existing mines and the development of our fourth mine at El Compas into commercial production by the end of July. 

“Our quarterly production profile should continue to improve this year as Guanacevi benefits from the productivity optimization program now underway and Bolañitos and El Cubo continue mining higher silver grades as per their 2018 mine plans. Metal recoveries were a bit lower than planned in Q1, 2018 but are expected to improve during the year.”

Operations Summary for First Quarter, 2018

At Guanacevi, mine output was lower due to mine development falling behind schedule in 2017 and the reallocation of mine personnel to implement a productivity optimization program. Silver and gold grades were both higher due to better dilution control, so that silver equivalent production in Q1, 2018 was only slightly lower than Q1, 2017.  Mine output, development and productivity should improve in Q2, 2018.

At Bolañitos, mine output and silver grades were higher but gold grades were lower due to variations within the LL-Asunción vein.  Silver equivalent production in Q1, 2018 was significantly higher than Q1, 2017.  Grades are expected to return to plan during the year.   

At El Cubo, mine output, silver grades and gold grades were all higher in Q1, 2018 compared to Q1, 2017, which resulted in a sharp increase in production in Q1, 2018.

El Compas Mine Development Project Update

The El Compas mine development project remains on schedule for mine and plant commissioning to commence in April and commercial production to be achieved by the end of July.

El Compas finally received its explosives permit in March, which allowed the mine to accelerate the development of the main access ramp.  The main ramp was at 355 metres as of March 31.  The San Juan vein was intersected and 28 metres were developed along the vein.  Mining should commence on the main El Compas vein later this month. 

The last plant component, a mobile crushing circuit, arrived on site in March and is currently being installed. The rest of the plant, tailings dam and surface infrastructure construction projects are essentially complete. A small stockpile of low grade ore has been started.
