Klondex Comments on Report

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sept. 10, 2014) - Klondex Mines Ltd. (TSX:KDX)(OTCQX:KLNDF) ("Klondex" or the "Company") provides comments on Mine Safety and Health Administration's ("MSHA") final report of the accident at the Midas mine.

Brent Kristof, Klondex Mines Chief Operating Officer commented, "Klondex recently received MSHA's report on the tragic accident resulting in the death of Rich Otto at our Midas Mine. The tragic loss of our co-worker, friend, and employee affected us very deeply. Rich Otto was an experienced miner with over 32 years in mining. He was organized, safety conscious and was often used to train other employees. He would never have allowed himself to work in the conditions alleged by MSHA. Safety is and has always been our first priority at Klondex. Our Fire Creek Project was recently recognized for its outstanding safety performance by the Nevada Mining Association in the small underground mine category. We applied this same level of safety to our Midas Mine upon its acquisition in 2014."

Mr. Kristof continued, "Despite our complete cooperation with MSHA during the investigation, we believe that MSHA failed to consider critical information and reached conclusions which don't appear to be supported by the evidence in the report. The report fails to analyze root causes of the accident or explain how the physical evidence and facts support its conclusions. We have contested the enforcement actions taken by MSHA and are continuing to challenge the unsupported allegations in the report."
