VANCOUVER, BC--(Marketwired - October 23, 2015) - Klondex Mines Ltd. (TSX: KDX) (NYSE MKT: KLDX) ("Klondex" or the "Company") is pleased to report its third quarter operating results for fiscal year 2015 from its Midas Mine and Fire Creek Project. Below is a table highlighting key operating metrics for the Company.

1. Gold equivalent ounces ("GEOs") are the gold ounces plus the silver ounces divided by a GEO ratio. GEO ratios are computed by dividing the average realized gold price per ounce by the average realized silver prices per ounce received by the Company in the respective period. GEO ratios were approximately 71.2:1, 73.2:1 and 76.9:1 for the first quarter, second quarter and third quarter of 2015, respectively, and 73.9:1 for the nine months ended September 30, 2015.

Paul Andre Huet, Klondex President and Chief Executive Officer commented, "Our operations continue to perform as planned. We had another strong operating performance in the third quarter selling 33,846 gold equivalent ounces and are now increasing our annual production guidance for the second straight quarter by another 5,000 ounces to between 130,000 and 135,000 gold equivalent ounces for the year, primarily due to additional working faces, positive reconciliations and ongoing dilution management at both Midas and Fire Creek."
