Endeavour Silver Reports Ball Mill Down for Repairs at Bolanitos Mine; No Material Impact on Production Anticipated

Endeavour Silver Corp. (TSX: EDR) (NYSE: EXK) announces that the 1,000 tonne per day (tpd) ball mill at the 1,600 tpd Bolañitos mine experienced an unplanned outage this week due to a motor problem. The motor has been sent out for repairs and the ball mill should be back up and running in about 2-3 weeks. No material impact on production is anticipated.The Bolañitos plant will continue to operate at 600 tpd during the repair period, and the downtime should not impact the expected Bolañitos mine output for the year because management previously guided the Bolañitos mine production would reduce to 1,000 tpd by mid-year. The outage may have a minor impact on forecast production in the second quarter from the El Cubo mine, located in the same district of Guanajuato as Bolanitos, because El Cubo is currently in the middle of a mine expansion from 1,500 tpd to 2,200 tpd. The additional mine tonnes were planned to be trucked for processing to the Bolañitos plant to take advantage of its available capacity. These additional El Cubo tonnes will now be stockpiled for processing in the third quarter.The El Cubo mine expansion is well under way, recording 7 days in excess of 2,000 tpd in May. A second mining contractor will commence work shortly to facilitate the mine expansion to 2,200 tpd. The El Cubo plant was optimized in the first quarter and is now operating well above its original design capacity of 1,500 tpd.
