April 2, 2013

VANCOUVER, BC and ELKO, NV--(Marketwired - Apr 2, 2013) - Klondex Mines Ltd. ( TSX : KDX ) ( OTCQX : KLNDF ) ("Klondex") today announces that it has entered into a toll milling agreement with Veris Gold Corp. ("Veris Gold") to process Klondex material from its Fire Creek project near Elko, Nevada.

Under the terms of the agreement, Veris Gold will accept for processing, delivery of the Fire Creek material to the Jerritt Canyon Mill, approximately 120 miles northeast of Fire Creek. Klondex will pay to Veris Gold the costs to mill and transport the mineralized material and a toll-milling fee with quarterly adjustments reflecting the change in contributing costs associated with processing of mineralized material. All precious metals milled pursuant to the agreement will be the property of Klondex. The total costs for shipping (transportation) and milling will be $148.50 per ton. Klondex will receive the recoveries achieved by Veris Gold's circuit.

Mike Doolin, General Manager of the Fire Creek project, stated, "I'm happy to report we continue to gain momentum in the development of the Fire Creek gold project towards a production decision via our bulk sampling program. Finalizing this milling agreement is another major step forward for us, and we are extremely pleased to be working with the team at Veris Gold."

Paul Huet, Klondex Mines CEO, commented, "The Nevada team delivers another important milestone for Klondex; the group has a reputation of consistently delivering and this is another great example. 2013 is a pivotal year for us as we continue to de-risk the Fire Creek asset. The excavation of the secondary egress, necessary to begin our bulk sampling, is now 20% complete and is on-track to be commissioned mid-June, 2013. Now, through this milling agreement with Veris Gold, we have a place to process mineralized material from Fire Creek. I have had the opportunity to work with this group at Veris Gold in the past and look forward to a continued relationship with such a professional team."

Randy Reichert, Co-CEO and COO of Veris, stated, "This second toll milling agreement adds to our third party ore processing revenue stream and provides an excellent additional source of ore as the Klondex team ramps up their mining operations into 2014. This agreement will further reduce our costs by making use of the excess capacity at the Jerritt Canyon Mill when we begin processing the Fire Creek ore in the third quarter of 2013. We look forward to working with yet another gold producing neighbour in Nevada."
