Cautionary Note Regarding Forward-Looking Information

This presentation contains certain information that may constitute forward-looking information under applicable Canadian and U.S. securities legislation, including but not limited to information about results of exploration, development, mining, evaluation activities, results of reclamation activities, the estimation or realization of mineral resources and mineral reserves, the timing and amount of estimated future production, the making of future production decisions, expectations regarding realization of synergies relating to Klondex's projects, the timing and receipt of required permits and approvals, capital expenditures, costs and timing of the development of new mineral deposits, requirements for additional capital, the sufficiency of working capital and liquidity, and the future prices of precious and base metals. This forward-looking information entails various risks and uncertainties that are based on current expectations, and actual results may differ materially from those contained in such information. These uncertainties and risks include, but are not limited to, the strength of the global economy; the price of gold; operational, funding and liquidity risks; the degree to which mineral resource and mineral reserve estimates are reflective of actual mineral resources and mineral reserves; the degree to which factors which would make a mineral deposit commercially viable are present; the risks and hazards associated with underground

  • perations; the ability to integrate acquisitions; and the ability of Klondex to fund its substantial capital requirements and operations. Risks and uncertainties about the Company’s

business are more fully discussed in the Company’s annual report on Form 10-K and periodic disclosure materials filed with the securities regulatory authorities in Canada and the U.S. and available at www.sedar.com and www.SEC.gov, respectively. Readers are urged to read these materials. Klondex assumes no obligation to update any forward-looking information

  • r to update the reasons why actual results could differ from such information unless required by law.

U.S. Cautionary Note Regarding the Use of Mining Terms

This presentation has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. All resource and reserve estimates included in this presentation have been prepared in accordance with NI 43-101. NI 43- 101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. These standards differ significantly from the mineral reserve disclosure requirements of the U.S. Securities and Exchange Commission (the “SEC”) set out in industry guide 7. In particular, the SEC’s industry guide 7 applies different standards in order to classify mineralization as a reserve. As a result, the definitions of proven and probable reserves used in NI 43-101 differ from the definitions in SEC industry guide 7. Under SEC standards, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. However, Klondex’s estimated proven and probable reserves previously reported under NI 43-101 for Fire Creek, Midas, Hollister and True North are equivalent to those determined under SEC Industry Guide 7. This presentation also uses the terms “resources”, “measured resources”, “indicated resources” and “inferred resources”. United states investors are advised that, while such terms are recognized and required by Canadian securities laws, the SEC does not recognize them. Mineral resources that are not mineral reserves do not have demonstrated economic

  • viability. United States investors are cautioned not to assume that all or any part of measured or indicated resources will ever be converted into reserves. Further, inferred resources

have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part of the inferred resources will ever be upgraded to a higher category, and it is uncertain if further exploration will result in upgrading them to an indicated or measured resource category. Disclosure of “contained

  • unces” in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute “reserves”

by SEC standards as in- place tonnage and grade without reference to unit measures. Consequently, resource information contained in this presentation is not comparable to similar information that would generally be disclosed by U.S. companies in accordance with the rules of the SEC.

Qualified Person

Brian Morris, Senior Vice President, Exploration of Klondex Mines is a "qualified person" as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects (NI 43-101) and has reviewed and is responsible for the technical information contained in this presentation.

Non-GAAP Performance Measures

We have included the non-GAAP measures "Production cash costs per gold equivalent ounce sold", "All-in sustaining costs per gold

  • unce sold" and "All-in costs per gold ounce sold“ in this presentation (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 and sustain

  • ur 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 current and future operations, development, exploration, and life-of-mine plans 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

  • f 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 using 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 sustaining costs per gold ounce sold

All-in sustaining cost ("AISC") amounts are intended to provide additional information only and do not have any standardized meaning prescribed by GAAP and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. The measures are not necessarily indicative of operating profit or cash flow from operations as determined under GAAP. Our calculation of AISC 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. AISC per gold ounce sold reflects 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. AISC per gold ounce 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

  • f net realizable value write-downs on production-related inventories (2) general and administrative expenses, (3) asset

retirement and accretion expenses, and (4) sustaining 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.

All-in costs per gold ounce sold

All-in costs per gold ounce sold includes additional costs which reflect the varying costs of producing gold over the life-cycle of a mine or project. We calculate our all-in costs per gold ounce sold by beginning with the AISC total and adding non-sustaining (growth) capital expenditures and exploration and development expenditures. AISC per gold ounce sold and all-in costs per gold ounce sold are presented in the tables below (in thousands, except ounces sold and per ounce amounts):

Klondex has not reconciled forward-looking full year non-GAAP performance measures contained in this presentation 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.
