Klondex Mines Ltd. (TSX: KDX) (OTCQX: KLNDF) ("Klondex" or the "Company") today provides an update on recent underground drilling from its Midas Mine in Elko County, Nevada (See FIGURES 1-4).

The focus of our 2015 Phase I drill program at Midas is to drill untested areas and to expand on known high grade shoots in close proximity to the existing infrastructure. Our drilling targeted gaps in the recently published Midas mineral resource estimate, and followed up on historic high grade drill intercepts on the 505, 705 and 905 Veins. Since January 2015, 40 underground core holes have been drilled from multiple platforms for a total of approximately 7,600 meters (25,000 ft) (see TABLE 1). 

Brian Morris, VP Exploration and Geology Services of Klondex, commented, "These drilling results are very exciting, having the potential to add significant mineral resources at Midas. Of particular interest are the results from the newly identified mineralized zone on the 505 Vein, which lies only 100 feet east of the current development and has the potential to be incorporated into the 2015 mine plan. Furthermore, the drilling on the 905 Vein further to the east confirms the presence of high grade mineralization to the south of Spiral 8."

Mr. Morris continued, "Phase II of the 2015 drill program will follow up on these new zones, which remain open both laterally and vertically. Additional step-out drilling will delineate the margins of the high grade mineralization, with the goal of expanding on these promising, near-mine targets."

Assays were performed by American Assay Laboratories (AAL) of Reno, Nevada an ISO 17025 accredited laboratory as directed under the supervision of Klondex staff.
