(TSX: KDX; OTCQX: KLNDF)("Klondex" or the "Company") today announces it has filed its unaudited consolidated financial results for the first quarter ending March 31, 2014.

In the first quarter 2014, the Company realized revenue from sales of precious metals for the first time in its history through its income statement.

Klondexs full financial results for the first quarter are available on SEDAR, at www.sedar.com and also have been posted on the Companys web site at www.klondexmines.com Dollar amounts are in Canadian dollars unless otherwise stated.

A conference call will be held tomorrow at 10:30 am EST; details are at the bottom of this press release. Paul Huet, Klondex President and CEO, stated, "In the first quarter, we made significant progress with our strategy to build Klondex into a leading integrated precious metals producer.

In February, we acquired and successfully integrated the Midas mine and mill into Klondexs operations, providing a strong platform for growth and creating value for our shareholders.

We are pleased with the acquisition of the Midas mine and mill and remain on track to achieve free cash flows this year, and to process 43,500 AuEq ounces from Fire Creek in 2014, as set out in our recently announced independent preliminary economic assessment, in addition to production from the Midas mine." First Quarter Highlights Units Q1 2014 Gold equivalent production Ounces 16,052 Total mineralized material mined Tons 22,370 Recovery Au 94.5% Recovery Ag 94.3% Revenue $ 2,626,573 Net Income (loss) $ (2,411,623) Cash $ 7,638,711 Working Capital $ 2,054,260 The table below summarizes the activity for the first quarter of 2014: Gold Equivalent Ounces Recovered 16,052 Distribution of produced ounces Fire Creek revenue (sold) applied to mineral properties 2,438 Midas revenue (sold) 1,849 Finished goods, dore & refined metal 9,148 Work-in-process 2,617 Total 16,052 Financial Highlights For the three months ended March 31, 2014, the Company received payment of $3.3 million (US$3.0 million) from the sale of 2,439 ounces of gold delivered to the Midas mill in 2013.

This amount was reported as sale of mineralized material and credited to the carrying value of Fire Creek mineral properties.

The Company also sold 930 ounces of gold and 58,053 ounces of silver from Midas that were recorded as revenue.

At March 31, 2014, the Company had finished goods and work-in-process inventory of 11,765 gold equivalent ounces which we anticipate will generate approximately $15 million in cash flow for use in operations.

Subsequent to the quarter, in early April, the Company recorded revenue and received payment of US$8.7 million for 6,620 ounces of gold sold under Fire Creeks gold supply agreement for its March refined gold production. The production costs for the quarter were $1.7 million or $906 per gold equivalent ounce.

Production costs per gold equivalent ounce is a non-IFRS measure and is discussed below.

The depreciation and depletion costs were $1.7 million.

The gross profit was $0.7 million. General and administrative expenses in the quarter were $2.2 million (2013 Q1 - $1.0 million).

The increase in general and administrative expenses was mainly due to an increase in employee and share-based compensation (principally for additional personnel), legal and regulatory expenses and other general expenses associated with the growth of the Company from an exploration stage company to one with two producing properties.

The Company recognized $1.9 million in business acquisition costs from the purchase on the Midas mine and mill from Newmont, a $0.6 million gain on the fair value of a derivative related to a gold supply agreement and $1.5 million in finance charges principally related to financing agreements entered into for the acquisition of the Midas mine and mill. The Midas Project After entering into a stock purchase agreement in December 2013 with Newmont Midas Holdings Limited, a wholly-owned subsidiary of Newmont USA Limited, Klondex Holdings USA Inc., a wholly-owned subsidiary of the Company, acquired the Midas mine and mill on February 11, 2014.

The purchase price of the acquisition was approximately US$55 million in cash and the issuance by the Company to Newmont USA of 5 million warrants to purchase common shares of Klondex at an exercise price of $2.15, with a 15-year term, which are subject to acceleration in certain circumstances.

The Company was also required to deposit approximately $28 million for reclamation bonds to replace Newmont USAs surety arrangements with Nevada and federal regulatory authorities.

In addition, the Company paid approximately US$3 million for a mining tax which was associated with the acquired company. The acquisition was funded by a three-part financing consisting of a $42.6 million subscription receipt equity financing, a $25 million debt financing and a US$35 million gold purchase agreement and royalty from Franco-Nevada Corporation.

The 2.5% royalty to Franco-Nevada will begin in 2019, after the gold under the gold purchase agreement is delivered. Midas Mine Mineral and waste development at Midas totaled 334 m (1,098 ft) and 268 m (880 ft), respectively, in the first quarter of 2014.

The Company extracted a total of 16,145 tons of mineralized material containing 1,945 ozs Au and 182,622 ozs Ag in the quarter. Midas Mill The Companys Midas mill started operations on February 19, 2014.

During the last five weeks of the quarter, the mill processed 13,961 tons of Midas material containing 1,726 ozs Au and 157,918 ozs Ag, and 7,766 tons of Fire Creek material containing 10,027 ozs Au and 10,027 ozs Ag. Gold and silver recoveries achieved for the quarter were 94.5% and 94.3%, respectively. Total metal recovered from both the Fire Creek and Midas operations was 13,545 ozs Au and 158,372 ozs Ag, for a total of 16,052 ozs AuEq (63 ounces of silver :1 ounce of gold). Subsequent to the quarter, Klondex signed a toll milling agreement with French Gulch Mining Corporation to process gravity concentrates from the Washington Mine in California. The Company is currently in discussions with other groups for additional toll milling agreements. Permitting Required production permits at Midas have been maintained since operations began in 1998.

Klondex has begun to assess the options for permitting a new tailings impoundment or expanding the current tailings. Exploration The Company has initiated exploration drilling and underground mining in the 7-4640 South area of the Midas Mine.

The Company began an underground exploration drilling program at Midas, in March of 2014, to develop the southern portion of the eastern veins.

A total of 3,702 m (12,179 ft) of underground drilling was completed during the first quarter, with assays expected in the second quarter 2014. Fire Creek Project The Company continues to transition the Fire Creek Exploration Project into a fully-permitted operation in 2015.

Subsequent to the quarter, Klondex announced the results of an independent Preliminary Economic Assessment ("PEA") for its wholly-owned Fire Creek project ("Fire Creek" or the "Project") near Elko, Nevada, including expected all-in sustaining cash costs of $636/oz Gold (April 29, 2014 The PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves.

There is no certainty that the PEA will be realized.

Mineral resources that are not mineral reserves do not have demonstrated economic viability. Operations The current bulk sampling program is expected to continue throughout 2014, to evaluate mining methods and the metallurgical characteristics of the Fire Creek material. Mineral and waste development at the Fire Creek Project totaled 139 m (457 ft) and 189 m (621 ft), respectively in the first quarter of 2014.

A total of 66 m (218 ft) and 73 m (239 ft) of mineral development was completed on the Joyce Vein and Vonnie Vein, respectively, in the quarter.

The Company extracted a total of 6,225 tons of mineralized material, containing 6,244 ozs Au and 7,393 ozs Ag in the quarter. Subsequent to the quarter, Klondex announced that it began initial drifting at Fire Creek Project on the newly discovered Karen Vein, located 45.7 m (150 ft) west of the main decline, parallel to the Joyce Vein and Vonnie Vein.

As of May 5, 2014, 25 m (82 ft) of exploration development had been completed along strike of the Karen Vein.

The weighted average grade of samples from the Karen Vein was 74.9 g/t (2.18 opt) Au with an average width of 0.5 m (1.5 ft) (May 5, 2014 Permitting Currently, Klondex is operating Fire Creek under a small scale mining permit which allows for the extraction of up to 120,000 tons of mineralized material over a three year period.

During the quarter, full-production baseline investigations and data collection continued. The Rapid Infiltration Basins are expected to be permitted and constructed during Q2 2014.

The completion of the RIB will mark the final construction project at Fire Creek. Exploration The Company continued underground infill drilling during the first quarter of 2014, testing the continuity and extent of the Joyce Vein and Vonnie Vein.

In addition, underground drilling to test the West Zone was completed from existing infrastructure. Assays were announced May 5, 2014 A total of 2,788 m (9,171 ft) of underground drilling was conducted in the first quarter. The Fire Creek project continues to indicate the potential for exploration upside, with exploration totaling only 7% of the total land position.

Klondex plans to fund a $5 million infill and exploration drilling program with cash from operations.
