RENO, NV--(Marketwired - April 19, 2017) - Klondex Mines Ltd. (TSX: KDX)(NYSE MKT: KLDX) ("Klondex" or the "Company") is pleased to report its preliminary operating results for the first quarter of 2017 for its Nevada and Canadian operations.

First Quarter 2017 Operating Highlights and Annual Outlook:

  • Mined a total 57,633 gold equivalent ounces(1), in line with Company expectations
  • Produced and sold a total of 34,454 and 33,737 gold equivalent ounces, respectively
  • In Nevada, ore from Fire Creek was stockpiled due to heavy snowfall limiting our ability to transport ore to the Midas mill
  • Built a significant stockpile in Nevada of 30,890 tons at an average grade of 0.94 gold equivalent ounces per ton containing 29,142 gold equivalent ounces(2). This is an increase of approximately 18,000 tons from the end of 2016. These tons will be processed at the Midas mill in the second quarter
  • Forward sold 20,000 of the stockpiled gold ounces in the first quarter at an average realized price of $1,250 per ounce
  • As planned, the Company continued to ramp up True North in Canada towards full production, which is expected to occur in the second half of the year
  • The Company's initial mineral resource estimate at Hollister is expected to be completed in the second quarter. Development work continued with ore silling in the Gloria zone; stockpiled ore is expected to be processed at the Midas mill in the third quarter
  • The Company remains on track to meet its annual production guidance of 210,000 to 225,000 gold equivalent ounces, up 36% from 2016
  • The Company will report its financial results for the first quarter of 2017 after market close on Thursday, May 4, 2017.

(1) Mined ounces are calculated using tons hauled to surface multiplied by the assays from production sampling.

(2) End of month surveys are used to account for tonnage. Grade of material is based on weighted average of representative samples taken during mining. A metallurgical balance, using mined and milled numbers, is performed to determine final stockpile balances.

Mr. Paul Huet, President and CEO commented, "Despite difficult weather conditions in Nevada, our underground mining activities performed as expected in the first quarter. We have built a substantial stockpile at the Midas mill that will be processed in the second quarter." Mr. Huet continued, "First quarter production was largely from two mines, Fire Creek and Midas in Nevada. Our True North and Hollister operations will contribute more in the second half of the year as they continue to ramp up towards full production. We are well positioned to deliver on our annual Company-wide production guidance of 210,000 to 225,000 gold equivalent ounces."

(1) Gold equivalent ounces ("GEO") and grades are computed as the applicable gold ounces/grade plus the silver ounces/grade divided by a GEO ratio. GEO ratios are computed by dividing the average realized gold price per ounce by the average realized silver price per ounce received by the Company in the respective period. Preliminary GEO ratios for each respective segment are as follows:  
GEO Ratio  68.7   68.7   68.7   68.7   68.8   68.7  
(2) The Company does not track this silver statistic at True North due to silver being trivial to that operation.  

Fire Creek and Midas in Nevada:

At Fire Creek and Midas, the Company mined 71,883 ore tons in the first quarter at an average mined head grade of 0.72 gold equivalent ounces per ton. First quarter 2017 production in Nevada was impacted by heavy snowfall that limited the ore mined from Fire Creek from being transported to the Midas mill. As such, the Company shut down the mill for just over two weeks to perform preventative maintenance originally scheduled for later in the year. The Company's mining activity performed as planned which resulted in 51,670 gold equivalent ounces mined. The Company built a significant ore stockpile containing 29,142 gold equivalent ounces at the end of the first quarter. The Midas mill has excess processing capacity so the stockpiled ounces will be processed in the second quarter of the year.

Hollister in Nevada:

At Hollister, sill development work began in the Gloria zone. The Company expects tons mined and mill head grades to progressively increase throughout the year as it transitions to bulk mining in the form of long-hole, cut-and-fill and selective shrink stoping. Stockpiled ore is expected to be processed at the Midas mill in the third quarter after metallurgical test work is completed.

In-fill drilling in the Gloria zone continues. During the first quarter, the Company completed 31 drill holes totaling 11,775 ft. Results are pending and the Company expects to generate a preliminary mineral resource and reserve estimate in the second and third quarter, respectively.

True North in Canada:

At True North in Canada, the mine continues to ramp up towards full production. First quarter production was primarily from lower grade areas on the 16 Level and the 2603 ramp where development was already in place. The Company also experienced lower than expected underground equipment availability in the first quarter and consequently accelerated planned mill maintenance originally scheduled to occur later in the year.

The Company expects 2017 production and grades to progressively increase throughout the year as mining activity moves to the higher grade 710 incline and decline zones, with 2017 production heavily weighted in the second half of the year.

2017 Guidance:

The Company reiterates its 2017 consolidated production guidance of 210,000 to 225,000 gold equivalent ounces. 2017 production is weighted more heavily in the second half of the year as True North and Hollister continue to ramp up towards full production.
