Endeavour Silver Reports Guanacevi Primary Ball Mill Trunnion Failure

Endeavour Silver Corp. 

(“Endeavour” or the “Company”)

(NYSE: EXK; TSX: EDR)

reports the trunnion on the primary ball mill at the Guanacevi mill has failed and could take up to 12 weeks to replace. As a result, processing of material at the Guanacevi mill has been suspended. Management is assessing several alternatives including operating at a significantly reduced capacity with minor conveyor modification using smaller regrind mills until the primary ball mill is operational.

This downtime will impact Q3 production and is expected to impact annual production and cost guidance. Management is conducting an evaluation and analysis this week and will provide an update as soon as its assessment is complete.
