Proposed Transaction with Hecla

On March 19, 2018, the Company announced that Hecla will acquire all of the outstanding shares of Klondex through a plan of arrangement. Hecla will acquire Klondex for consideration of $462 million comprised of cash and shares of Hecla common stock. Klondex shareholders will receive $2.47 per share in cash or shares of Hecla which represents a 59% premium to Klondex's 30-day volume-weighted average price at March 16, 2018 and a premium of approximately 72% based on the closing price on March 16, 2018. Klondex's Canadian assets will be spun out to its existing shareholders. Klondex shareholders will receive, for each Klondex share, 0.125 of a common share of a newly formed company which will own Klondex's Canadian assets.

The closing of the transaction is subject to certain conditions including shareholder and regulatory approvals. Additional details regarding the transaction will be available in the preliminary proxy statement that is expected to be filed with regulatory agencies in May. Pending receipt of all required approvals, the Company anticipates that the transaction will be completed around the end of the second quarter of 2018.

First quarter 2018

First quarter 2018 revenues increased compared to the first quarter of 2017 due to more ounces sold and a higher price per ounce of gold. Increases in production costs during the first quarter of 2018, as compared to the same period in 2017 were driven by the operations at Hollister and Aurora, which were not operating during first quarter 2017. General and administrative costs for the first quarter of 2018 increased as compared to the prior year period primarily due to severance costs related to the restructuring of the True North operations in early January of 2018. The decrease in Development and project costs during the first quarter of 2018 was due to expenses incurred at Hollister and Aurora during the first quarter of 2017. The Company incurred a foreign currency gain of $3.2 million during the first quarter of 2018 compared to a foreign currency loss of $1.0 million for the first quarter of 2017.

Net loss for the first quarter of 2018 was $8.0 million or $0.04 per share (basic and diluted). The first quarter of 2018 includes $3.6 million for costs related to the pending acquisition of Klondex by Hecla. Excluding the net impact of these costs, the Company's adjusted net loss(1) for the quarter was $5.1 million or $0.02 per share (basic and diluted).

(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. Mined ounces are calculated using tons hauled to surface multiplied by the assays from production sampling.
(2)  The Company does not track this silver statistic at True North due to silver being immaterial to that operation.
(3) This is a non-GAAP measure; refer to the Non-GAAP performance measures section of this Press Release for additional detail.
(4) Aurora activity is a result of processing historical Hollister tailings at the Aurora mill.

Nevada operations

The Company's Nevada operations mined 92,303 ore tons at an average mined head grade of 0.51 GEOs per ton during the first quarter of 2018. The Company mined and produced a total of 47,499 and 41,415 GEOs, respectively, at its Nevada operations during the first quarter of 2018. Total GEOs produced for the first quarter included approximately 3,700 ounces from the Hollister ore stockpile that were sold to and processed by a third party.

Canada operations

During the first quarter, the True North mine transitioned from operating to care and maintenance. During the transition, 19,301 ore tons were mined from areas that were developed prior to the Company's decision to place the True North operation on care and maintenance in early January of 2018. The Company mined and produced a total of 2,374 and 2,111 GEOs, respectively, at its Canada operations during the first quarter of 2018. Consistent with management plans, no ounces were processed from tailings at True North during the first quarter of 2018. Processing of tailings at the True North mill has now resumed due to warmer weather conditions.

Non-GAAP performance measures

We have included the non-GAAP measures "Adjusted net loss", "Production cash costs per gold equivalent ounce sold", "All-in sustaining costs per gold 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 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 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 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, except for adjusted net (loss) income.

Adjusted net loss

The Company believes the use of adjusted net loss allows management, investors, and analysts to understand its net (loss) income related to its primary business. For the first quarter 2018, costs related to the pending acquisition of Klondex by Hecla have been excluded from net loss. Net loss is reconciled to adjusted net loss in the table below (in thousands, except per share amounts):

		Three months ended March 31, 2018

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 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):

		Three months ended March 31, 2018
		Nevada Total				True North				Total

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 of 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):

		Three months ended March 31, 2018
