Klondex Generates Third Quarter 2015 Operating Cash Flow of US$13.3 Million; Increases Cash by US$5.8 Million and Eliminates Senior Notes in Full

VANCOUVER, BC--(Marketwired - November 11, 2015) - Klondex Mines Ltd. (TSX: KDX) (NYSE MKT: KLDX) ("Klondex", the "Company", "we", "our", or "us") is pleased to announce its operational and financial results for the third quarter of 2015. This release should be read in conjunction with our third quarter 2015 unaudited financial statements and related management's discussion & analysis ("MD&A"), which are available on our website (www.klondexmines.com), on SEDAR (www.sedar.com), and on EDGAR (www.sec.gov).

All dollar amounts included in this press release are expressed in thousands of United States dollars unless otherwise noted.

Quarterly Highlights

• Health, Safety, and Environmental - No lost-time injuries and have now operated ~three years at our Fire Creek project ("Fire Creek") and ~one year at our Midas mine and ore milling facility ("Midas") without a lost-time injury.
• Cash Flows and Liquidity - Increased our cash balance by $5.8 million to $60.3 million and prepaid in full $17.6 million of principal on the 11.0% senior secured notes ("Senior Notes") with the proceeds received from a September public offering.
• Ounces Sold and Revenues - Sold 33,853 gold equivalent ounces ("GEOs"), consisting of 27,934 gold ounces and 454,611 silver ounces. Revenue totaled $38.4 million from average selling prices per gold and silver ounce of $1,135 and $14.78, respectively, and net income was $4.1 million (or $0.03 per share - basic).
• Performance Measures - Significant margins from operations of ~45% (Revenues less Production costs) and remain on track to achieve full-year cost outlook. Third quarter cash costs per GEO were $621 bringing our year-to-date cash cost per GEO to $637.
• Operations - Produced 32,076 GEOs, consisting of 26,300 ounces of gold and 443,576 ounces of silver. We now anticipate full-year 2015 GEO production of between 130,000 to 135,000 ounces, an increase of 5,000 GEOs from our previous estimate.
• Exploration Results - Released updated mineral resource estimates and continued to encounter high gold grades in both new and existing veins of mineralized material to the west and south at Midas and to the west at Fire Creek. Advanced the ore development on the 905 vein at Midas an additional unplanned 300 feet due to discovery of new high grade mineralization.

Paul Andre Huet, President and Chief Executive Officer said, "We had another strong quarter both operationally and financially. Raising annual production guidance for the second consecutive quarter is a reflection of this performance and the tremendous efforts from the entire Klondex team. Additionally, despite lower grades in the third quarter compared to the first half of the year, our year-to-date cash costs per GEO sold actually decreased from the second quarter as a result of managing our costs and becoming more efficient at our operations. We also continued to strengthen our balance sheet by increasing our cash balance by approximately $6 million during the quarter and completely repaying our Senior Notes."

2015 Full Year Outlook

As a result of the 97,269 GEOs produced (99,461 GEOs sold) during the first nine months of 2015, we now anticipate our full-year 2015 GEOs produced will total approximately 130,000 to 135,000 ounces, an increase of 5,000 GEOs from the previous estimate. We expect our fourth quarter GEO production to increase from the third quarter, with a majority of the additional ounces expected to be produced from Fire Creek as we plan on continuing to mine high grade material from longhole stopes. The first half 2015 production was better than planned due to higher tons and grades from Midas while the second half 2015 production is expected to benefit from higher tons mined and consistent grades at Fire Creek.

While we have increased our full-year projections for GEO production, we are maintaining our outlook for production costs and capital expenditures, which are summarized in the following table and presented with unaudited results for the nine months ended September 30, 2015.

⁽¹⁾ Gold equivalent ounces produced (or gold equivalent grades per ton) are the gold ounces produced (or gold grades) plus the silver ounces produced (or silver grades) 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 us in the respective period and match the ratios used to determine the production cash costs per GEO sold.

Third Quarter Selected Financial Information

During the three and nine months ended September 30, 2015, Fire Creek and Midas together sold 27,934 and 81,837 gold ounces, respectively, and 454,611 and 1,302,419 silver ounces, respectively. Revenues, Production costs, and Depreciation and depletion increased during the three and nine months ended September 30, 2015 from the same periods of 2014 as the Midas acquisition was completed in February 2014, after which we began increasing production at both Midas and Fire Creek. Increases in Revenues in the 2015 periods from higher volumes have been partially offset by lower average realized selling prices.

During the three and nine months ended September 30, 2015, we recorded a $2.1 million Loss on extinguishment of senior notes when we prepaid in full $17.6 million of principal.

Third Quarter Liquidity and Capital Resources

Following a September 2015 public offering, we significantly improved our liquidity and financial position by voluntarily repaying the entire outstanding principal balance of the Senior Notes. We received net proceeds from the equity offering of $18.6 million, which were used to repay the June 30, 2015 Senior Notes principal balance of $17.6 million. We incurred an early prepayment penalty of 4% which totaled $0.7 million and was paid during the third quarter of 2015.

Our cash balance increased from the end of the prior quarter of 2015 by 10.6% to $60.3 million as we generated $13.4 million in operating cash flows, used $9.7 million in investing activities, and received $2.7 million in financing activities.

Our working capital increased $14.2 million (approximately 29.5%) from December 31, 2014 to September 30, 2015, while our working capital ratio increased by 33.1%.

On a consolidated basis, Fire Creek's and Midas's third quarter 2015 results included the sale of 33,853 GEOs, consisting of 27,934 gold ounces and 454,611 silver ounces, as increased metal production from Fire Creek was offset by lower metal production from Midas due to lower average grades associated with the mining sequence. Grades at Midas are expected to increase in the fourth quarter. To lessen the impact of Midas's lower grades on our quarterly consolidated ounce production, we increased the volume of tons milled from both Midas and Fire Creek.

Fire Creek performed well during the third quarter of 2015, with an average daily milling rate of approximately 248 tons per day (216 tons per day in the second quarter of 2015), an average gold mill head grade of 0.97 oz/ton (1.00 oz/ton in the second quarter of 2015), and quarterly gold production of 20,843 ounces (18,558 gold ounces produced in the second quarter of 2015). Gold production increased during the third quarter of 2015 from the previous two quarters due to higher tons milled as we had access to additional working faces, including the ability to longhole stope in the Karen vein which accounted for approximately 15% of the ore tons mined during the third quarter of 2015. The longhole stoping program has improved our production rates and costs from the first six months of 2015 while maintaining the average gold mill head grade and we expect such trend to continue during the fourth quarter.

Midas's operations during the third quarter of 2015 included an average daily milling rate of approximately 523 tons per day, an average gold mill head grade of 0.12 oz/ton, and an average silver mill head grade of 9.27 oz/ton, quarterly production totaled 5,457 gold ounces and 419,758 silver ounces. During the third quarter of 2015, the lower grades were a result of mine sequencing. We advanced the ore development in the high grade 905 vein an additional unplanned 300 feet due to the discovery of high grade south extensions into previously unrecognized mineralized material. We expect the ore grades will increase during the fourth quarter of 2015 as we return to longhole stoping in the 905 vein, as well as bringing the recently discovered 505 vein into production.

Cautionary Note Regarding Technical Information and Forward-looking Information

A production decision at the Fire Creek Project has not been made by Klondex, as it is still in the bulk sampling phase. Although a production decision at the Fire Creek Project has not been made, the mineralized material extracted from the Fire Creek Project under the bulk sample permit is processed through the Midas mill.

A production decision at the Midas mine was made by previous operators of the mine, prior to the completion of the acquisition of the Midas mine by Klondex and Klondex made a decision to continue production subsequent to the acquisition. This decision by Klondex to continue production and, to the knowledge of Klondex, this production decision was not based on a feasibility study of mineral reserves demonstrating economic and technical viability prepared in accordance with NI 43 -101. Readers are cautioned that there is increased uncertainty and higher risk of economic and technical failure associated with such production decisions.

Non-IFRS Performance Measures

We have included the non-IFRS measures "Production cash costs per gold ounce sold on a by-product basis", "Production cash costs per gold equivalent ounce", and "All €in sustaining costs per ounce" (collectively, the "Non-IFRS Measures") in this press release. These Non-IFRS Measures are used internally to assess our operating and economic performance and to provide key performance information to management. We believe that these Non-IFRS Measures, in addition to conventional measures prepared in accordance with IFRS, provide investors with an improved ability to evaluate our performance and ability to generate cash flows required to fund our business. These Non-IFRS Measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. These Non-IFRS Measures do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to or consistent with measures used by other issuers or with amounts presented in our financial statements.

Our primary business is gold production and our future development and current operations primarily focus on maximizing returns from such gold production. As a result, our Non-IFRS Measures are calculated and disclosed on a per gold ounce basis.

Production Cash Costs Per Gold Ounce Sold on a By-product Basis

Production cash costs per gold ounce sold on a by-product basis presents our cash costs associated with the production of gold and, as such, non-cash depreciation and depletion charges are excluded. Production cash costs per gold ounce sold on a by-product basis is calculated on a per ounce of gold sold basis, and includes all direct and indirect operating costs related to the physical activities of producing gold, including mining, processing, third party refining expenses, on-site administrative and support costs, and royalties (State of Nevada net proceeds taxes are excluded), net of revenues earned from silver sales (table in thousands, except ounces sold and per ounce amounts):

⁽¹⁾ Includes ounces sold (if any) under the agreement dated as of March 31, 2011 and amended and restated as of October 4, 2011 between our indirect wholly-owned subsidiary, Klondex Gold & Silver Mining Company, and Waterton Global Value, L.P. (the "Gold Supply Agreement") and ounces delivered under the agreement dated February 11, 2014 between Klondex and Franco-Nevada GLW Holdings Corp. (the "Gold Purchase Agreement").
⁽²⁾ Excludes 2,439 gold ounces ($3.0 million in cash receipts) sold during the first quarter of 2014, the proceeds of which were used to reduce the carrying value of the Fire Creek mineral property.

Production Cash Costs per Gold Equivalent Ounce Sold

Production cash costs per gold equivalent ounce sold presents our cash costs associated with the production of gold equivalent ounces and, as such, non-cash depreciation and depletion charges are excluded. Production cash costs per gold equivalent ounce sold is calculated on a per gold equivalent ounce sold basis, and includes all direct and indirect operating costs related to the physical activities of producing gold, including mining, processing, third party refining expenses, on-site administrative and support costs, and royalties (State of Nevada net proceeds taxes are excluded). Gold equivalent ounces are computed as the number of silver ounces required to generate the revenue derived from the sale of one gold ounce, using average realized selling prices. Beginning with the second quarter of 2015, we began using realized selling prices instead of budgeted selling prices to calculate gold equivalent ounces and, as such, gold equivalent ounces presented below may differ from previously reported amounts (table in thousands, except ounces sold and per ounce amounts):

⁽¹⁾ Includes ounces sold (if any) under the Gold Supply Agreement and ounces delivered under the Gold Purchase Agreement.
⁽²⁾ Excludes 2,439 gold ounces ($3.0 million in cash receipts) sold during the first quarter of 2014, the proceeds of which were used to reduce the carrying value of the Fire Creek mineral property.

All-in Sustaining Costs per Gold Ounce Sold

All-in sustaining costs per gold ounce sold presents the full cost of gold production from our current operations, therefore, capital amounts related to expansion projects are excluded. Certain other cash expenditures, including State of Nevada net proceeds taxes, federal tax payments, and financing costs are also excluded. Our calculation of all-in sustaining costs per gold ounce is consistent with the June 2013 guidance released by the World Gold Council, a non-regulatory, non-profit market development organization for the gold industry.

We calculate our all-in sustaining costs per gold ounce sold on a consolidated basis as ore from both Fire Creek and Midas is processed at Midas and because general and administrative expenses are related to our mining operations as a whole. All-in sustaining costs per gold ounce sold includes all (1) direct and indirect operating cash costs related to the physical activities of producing gold, including mining, processing, third party refining expenses, on-site administrative and support costs, and royalties, (2) general and administrative expenses, (3) decommissioning provision accretion, and (4) sustaining capital expenditures, the total of which is reduced for revenues earned from silver sales (table in thousands, except ounces sold and per ounce amounts):

⁽¹⁾ Includes ounces sold (if any) under the Gold Supply Agreement and ounces delivered under the Gold Purchase Agreement.
⁽²⁾ Excludes 2,439 gold ounces ($3.3 million in cash receipts) sold during the first quarter of 2014, the proceeds of which were used to reduce the carrying value of the Fire Creek mineral property.

We define sustaining capital expenditures as those costs which do not contribute to a material increase in annual gold ounce production over the next 12 months. As such, sustaining capital expenditures exclude amounts for certain exploration activities, underground mine development in which the production benefit will be primarily realized in periods greater than the next 12 months, certain capital expenditures at the corporate office, and permitting activities related to expansion efforts. The following table reconciles sustaining capital expenditures to our total capital expenditures (in thousands):
