Mr. Paul Huet, President and CEO commented, "As previously announced, we had record quarterly and annual production in the fourth quarter and for the full year in 2016. Additionally, we are pleased that we once again achieved our production and cost guidance for the year." Mr. Huet continued, "Looking ahead, our near term strategy is focused on organic growth. We expect to produce between 210,000 and 225,000 gold equivalent ounces in 2017, an increase of approximately 36% from the prior year."

2017 full year outlook

We expect to produce between 210,000 and 225,000 gold equivalent ounces during 2017 at an expected production cash cost per GEO sold of $680 to $710 per GEO sold. This represents an increase in GEOs produced of approximately 36% from the prior year as we benefit from bulk sampling extraction at Hollister in Nevada as well as higher production from True North mine in Canada as ramp-up continues. Fire Creek and Midas' 2017 production is expected to be in line with the prior year.

We also expect our 2017 capital expenditures to be between $57 - $62 million with an additional $3 - $5 million to be spent on exploration. The majority of capital is expected to be spent at Fire Creek as we continue underground expansion in the form of primary access development and advancement of a second portal. We also expect to spend $7 - $9 million at our newly acquired Hollister mine in Nevada as it commences a bulk sampling mining program and underground definition drilling in the Gloria zone.

Below are tables summarizing key 2017 operating guidance.

Klondex has not reconciled forward-looking 2017 full year non-GAAP performance measures contained in this press release to their most directly comparable GAAP measures, as permitted by Item 10(e)(1)(i)(B) of Regulation S-K. Such reconciliations would require unreasonable efforts at this time to estimate and quantify with a reasonable degree of certainty various necessary GAAP components, including for example those related to future production costs, realized sales prices and the timing of such sales, timing and amounts of capital expenditures, metal recoveries, and corporate general and administrative amounts and timing, or others that may arise during the year. These components and other factors could materially impact the amount of the future directly comparable GAAP measures, which may differ significantly from their non-GAAP counterparts.

Consolidated Financial Results of Operations

Fourth quarter 2016

Fourth quarter Revenues reflect a quarterly high in terms of ounces sold, primarily due to higher tons mined at Fire Creek and Midas and commencing production at True North. Production costs and Depreciation and depletion also increased in the fourth quarter due to an increase in sales volumes. Write-down of production inventories in 2016 were recorded in the fourth quarter at Midas and True North due to lower period-end metal price levels and increases in production costs. Business acquisition costs were associated with the Hollister acquisition and Provision for legal settlement is related to litigation with a former employee.

Full year 2016

When compared to the prior year, 2016 Revenues increased as a result of increases in the number of gold ounces sold from higher tons mined at Fire Creek and Midas and commencing production at True North during the second half of 2016, the volumes of which were impacted by changes in average realized prices. Production costs and Depreciation and depletion increased from the prior period due primarily to an increase in sales volumes. General and administrative increased in 2016 due to increased staff levels at the corporate office, severance payments, and costs associated with our deferred share unit plan. Exploration spending was at Fire Creek and Midas while Development and projects costs were attributable to True North and Hollister.

Liquidity and Capital Resources

Fourth quarter 2016

Fourth quarter 2016 operating cash flows benefited from increases in ounce sales which were offset by lower average realized prices. The $98.1 million used in investing activities reflects the $80.0 million cash payment to complete the Hollister acquisition. Financing cash flows include the refinancing of the $12.0 million secured promissory note with a corresponding draw on the Revolver.

Full year 2016

During 2016 we generated $45.3 million of net operating cash flows which were positively impacted by higher production levels which increased the total cash margin from operations, offset by higher General and administrative, Exploration, and Development and projects costs. Cash used in investing activities included $100.0 million for acquisitions and $61.7 million for expenditures on mineral properties, plant and equipment. The issuance of share capital, which included a $95.7 million bought deal financing and option and warrant exercises, benefited our cash balances by $105.9 million and were slightly reduced for net debt borrowings and repayments.

Working capital and liquidity

We maintained our strong financial position and as of December 31, 2016, had total liquidity of $56.2 million, consisting of $33.2 million in working capital and $23.0 million of borrowing availability under our Revolver.

Fourth Quarter and Year To Date 2016 Summary Operational Results

Nevada operations

We achieved the full-year 2016 plan which entailed production growing from the first half to the second half of the year, as planned sequencing and ore development activities performed throughout the year contributed to quarter over quarter grade increases. As a result, consolidated gold equivalent mill head grades increased quarter over quarter in 2016 and were: 0.44 oz/ton in the first, 0.52 oz/ton in the second, 0.55 oz/ton in the third, and 0.57 oz/ton in the fourth. Production increased in 2016 to a record 151,007 GEOs. Full-year gold equivalent grades of 0.52 oz/ton in 2016 contributed to consistently low production cash costs per GEO of $637, resulting in a margin of $613 (or 49.0%) per ounce using average realized gold prices in 2016.

Canadian operations

We achieved True North's full-year 2016 plan which entailed production commencing in the third quarter from reprocessing tailings and increasing in the fourth quarter when stockpiled ore processing began. Actual production of 10,187 gold ounces was in the middle of our expected range of 8,000 - 12,000 gold ounces.

Non-GAAP performance measures

We have included the non-GAAP measures "Production cash costs per gold equivalent ounce sold" and "All-in costs per gold ounce sold" in this press release (collectively, the "Non-GAAP Measures"). These Non-GAAP Measures are used internally to assess our operating and economic performance and to provide key performance information to management. We believe that these Non-GAAP Measures, in addition to conventional measures prepared in accordance with GAAP, provide investors with an improved ability to evaluate our performance and ability to generate cash flows required to fund our business. These Non-GAAP 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 GAAP. These Non-GAAP Measures do not have any standardized meaning prescribed under GAAP, 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-GAAP Measures are calculated and disclosed on a per gold or gold equivalent ounce basis.

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, royalties, and cash portions of net realizable value write-downs on production-related inventories (State of Nevada net proceeds and other such taxes are excluded). We believe that converting the benefits from selling silver ounces into gold ounces is helpful to analysts and investors as it best represents the way we operate, which is to maximize returns from gold production. 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 (in thousands, except ounces sold and per ounce amounts):

All-in costs per gold ounce sold

Our calculation of all-in costs per gold ounce sold 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. All-in costs per gold ounce sold reflect the varying costs of producing gold over the life-cycle of a mine or project, including costs required to discover and develop new sources of production; therefore, capital amounts related to expansion and growth projects are included.

All-in 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, royalties, and cash portions of net realizable value write-downs on production-related inventories (2) general and administrative expenses, (3) asset retirement and accretion expenses, and (4) capital expenditures, the total of which is reduced for revenues earned from silver sales. Certain cash expenditures, including State of Nevada net proceeds and other related taxes, federal tax payments, and financing costs are excluded (in thousands, except ounces sold and per ounce amounts):
