Klondex Reports Record Quarterly Production of 41,436 GEOs

VANCOUVER, BC--(Marketwired - July 12, 2016) - - July 12, 2016- Klondex Mines Ltd. (TSX: KDX) (NYSE MKT: KLDX) ("Klondex" or the "Company") is pleased to report its preliminary production results for the second quarter of 2016 for its Fire Creek and Midas mines.

The progressive increase in GEO production during the second quarter of 2016 was primarily due to an increase in tons mined and milled. Average gold equivalent mill head grades at Fire Creek improved from the first quarter as the Company returned to mining higher grade zones. Average gold equivalent mill head grades improved slightly at Midas due to mine sequencing. The Company continues to expect the mill head grades at Midas to progressively increase throughout the year. Average silver recovery rates were slightly lower than expected due to higher mill throughput, which reduced ore retention time in the leach tanks.

The Company reiterates its 2016 production guidance of 145,000 to 150,000 GEOs, which is split approximately 45%-50% in the first half of 2016 and 50%-55% in the second half of 2016.

Mr. Paul Huet, President and CEO commented, "We achieved record GEO production for the Company in the second quarter and are on our way to accomplish our goal of filling the Midas mill. We are well positioned to meet our production guidance for the year as we expect our mining rates and mill head grades to be consistent with the second quarter results, or even improve slightly, according to our mine plans." Mr. Huet continued, "We remain on track to execute on our strategy, as we continue to make strong progress at the True North mine in Canada and we remain confident that we will be in position to make a production decision in the third quarter."
