Item 1.	Security and Issuer
	The class of equity securities to which this Schedule 13D relates is the common stock, no par value (the “Common Stock”), of Klondex Mines Ltd., a company existing under the laws of the Province of British Columbia (the “Issuer”). The principal executive offices of the Issuer are located at 6110 Plumas Street, Suite A, Reno, Nevada 89519.
Item 2.	Identity and Background
	This Schedule 13D is being filed jointly, pursuant to a joint filing agreement included as Exhibit 1 hereto, by:
	(i) Hecla Mining Company, a Delaware corporation (“Parent”). The principal office of Parent is 6500 North Mineral Drive, Suite 200, Coeur d’Alene, Idaho 83815-9408. Parent is a precious metals mining company.
	(ii) 1156291 B.C. Unlimited Liability Company, an unlimited liability company existing under the laws of the Province of British Columbia (“Acquireco” and together with Parent, the “Reporting Persons”). The principal office of Acquireco is 800 West Pender Street, Suite 970, Vancouver, BC, Canada V6C 2V6. Acquireco is a wholly-owned subsidiary of Parent formed for purposes of entering into the Arrangement described in Item 4. The name, business address, present principal occupation or employment and certain other information relating to each of the directors and executive officers of the Reporting Persons is set forth on Schedule A hereto, and is incorporated by reference.
	During the last five years, none of the Reporting Persons nor, to the best of the Reporting Persons’ knowledge, any of the persons listed on Schedule A attached hereto have (i) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, U.S. federal or state securities laws or finding any violation with respect to such laws.
Item 3.	Source and Amount of Funds or Other Consideration
	The Shareholders Agreements described in Item 4 of this Schedule 13D (the terms of which are hereby incorporated by reference) were entered into between Parent and each of Sentry Investments Inc. (“Sentry”), CI Investments Inc. (“CI”), William Matlack, Blair Schultz, Paul Huet, Ritch Hall, Barry Dahl, James Haggarty, and Rodney Cooper (each an “Individual Shareholder” and together with Sentry and CI, the “Shareholders”). Neither Acquireco nor Parent paid additional consideration to the Shareholders in connection with the execution and delivery of the Shareholders Agreements, and thus no funds were used for such purpose.

6

Item 4.	Purpose of Transaction
	Arrangement Agreement
	On March 16, 2018, Parent and Acquireco entered into an Arrangement Agreement (the “Arrangement Agreement”) with the Issuer. Under the terms of the Arrangement Agreement, Parent will acquire all of the outstanding shares of the Issuer (the “Arrangement”), and Issuer’s shareholders will receive total consideration with a value of US$2.71 per share (based on the market price of Parent common stock on March 16, 2018), consisting of (A) cash and Parent common stock, with a value (as of March 16, 2018) of US$2.47 per share, and (B) shares of a new company (“Spinco”) formed to hold the Issuer’s Canadian assets, with a value of US$0.24 per share of Spinco. The Issuer’s shareholders may elect to receive either (i) US$2.47 in cash (the “Cash Alternative”) or (ii) 0.6272 of a Parent share (the “Share Alternative”), or (iii) US$0.8411 in cash and 0.4136 of a share of Parent common stock (the “Combined Alternative”), currently valued at US$2.47, subject in the case of the Cash Alternative and the Share Alternative to proration based on a maximum total cash consideration of US$157,410,417 and a maximum total number of Parent shares issued of 77,411,859. The Issuer’s shareholders who fail to properly elect either the Cash Alternative or the Share Alternative will be deemed to have elected the Combined Alternative. If all shareholders elected either the Cash Alternative or the Share Alternative, as a result of proration each shareholder would be entitled to receive US$0.8411 in cash and 0.4136 of a Parent share. The Issuer’s shareholders will also receive 0.125 of a share of Spinco for each of the Issuer’s common shares (after giving effect to an 8:1 share consolidation in Spinco). As a result of the transactions contemplated by the Arrangement Agreement, each holder of a warrant of the Issuer will receive upon the exercise of such warrant such securities and other property, if any, which the holder is entitled to receive under the terms of their warrant. Pursuant to the terms of the Arrangement Agreement, at the effective time of the Arrangement, the directors and officers of the Issuer immediately prior to the effective time of the Arrangement will resign and be replaced in accordance with the Arrangement Agreement. In addition, pursuant to the terms of the Arrangement Agreement, at the effective time of the Arrangement and amalgamation, the articles and notice of articles of the combined entity of Acquireco and the Issuer will be in the form of Acquireco’s articles and notice of articles. If the Arrangement is completed, the shares of Common Stock will be delisted from the NYSE American LLC and the Toronto Stock Exchange and will be deregistered under the Exchange Act.

7

The Arrangement Agreement has been approved by the Board of Directors of each of the Issuer and Parent. The Arrangement is currently expected to close in the second quarter of 2018 and is subject to customary closing conditions, including, among others, the following: (i) the affirmative vote of holders of 66.67% of the outstanding shares of Common Stock, the affirmative vote of 66.67% of the affected shareholders of the Issuer voting as a single class, and, if applicable, the affirmative vote of a majority of the holders of the outstanding shares of Common Stock after excluding any votes of Parent and other persons required to be excluded under applicable law, in each case approving the Arrangement Agreement and the Arrangement; (ii) the expiration of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976; (iii) the accuracy of the representations and warranties therein of the parties thereto (subject in some cases to a material adverse effect standard); and (iv) material compliance by the parties thereto with their obligations under the Arrangement Agreement, including, among other things, covenants, subject to certain exceptions, of the Issuer to not solicit any Acquisition Proposals (as defined in the Arrangement Agreement) or change its recommendation to the shareholders of the Issuer to approve the Arrangement and the Arrangement Agreement.

The description contained in this Item 4 of certain principal terms of, and the transactions contemplated by, the Arrangement Agreement is qualified in its entirety by reference to the full text of the Arrangement Agreement, the terms of which are incorporated herein by reference to Exhibit 2 hereto.

The Arrangement Agreement contains representations and warranties that Parent and the Issuer made. The assertions embodied in those representations and warranties are qualified by information in a confidential disclosure letter that the Issuer has exchanged in connection with signing the Arrangement Agreement. While Parent does not believe that it contains information securities laws require Parent to publicly disclose other than information that has already been so disclosed, the disclosure letter does contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the Arrangement Agreement. Accordingly, the representations and warranties should not be relied on as characterizations of the actual state of facts, since they are modified in important part by the disclosure letter. Moreover, information concerning the subject matter of the representations and warranties may have changed since the date of the Arrangement Agreement, which subsequent information may or may not be fully reflected in public disclosures.

Shareholders Agreements

Sentry entered into a Support Letter Agreement with Parent, dated March 15, 2018 (the “Sentry Agreement”); CI entered into a Support Letter Agreement with Parent, dated March 16, 2018 (the “CI Agreement”); and each of the Individual Shareholders entered into separate Voting Agreements with Parent each dated as of March 16, 2018 (each a “Voting Agreement” and together with the Sentry Agreement and the CI Agreement, the “Shareholders Agreements”). The Shareholders collectively directly own or may be deemed to own or have control over 47,885,883 shares of Common Stock.

8

Pursuant to the Sentry Agreement, Sentry irrevocably agreed that, unless the Sentry Agreement has been terminated, Sentry will vote or cause to be voted all of the shares of Common Stock over which Sentry exercises control (the “Sentry Shares”) in favor of the Arrangement and will not exercise any rights of dissent provided under the Arrangement, any applicable laws or otherwise. Sentry further agreed that, until termination of the Sentry Agreement, it will (i) not sell, option, transfer or otherwise encumber the Sentry Shares; (ii) not solicit a competing transaction or otherwise knowingly take any action of any kind which is reasonably likely to reduce the likelihood of success of the Arrangement; (iii) not grant or agree to grant any proxy or other right to vote the Sentry Shares, or enter into any voting trust, vote pooling or other agreement with respect to the right to vote, call meetings of shareholders or give consents or approvals of any kind as to the Sentry Shares; and (iv) not do indirectly anything that Sentry has agreed not to do directly in the Sentry Agreement.

Pursuant to the CI Agreement, CI irrevocably agreed that, unless the CI Agreement has been terminated, CI will vote or cause to be voted all of the shares of Common Stock over which CI exercises control (the “CI Shares”) in favor of the Arrangement and will not exercise any rights of dissent provided under the Arrangement, any applicable laws or otherwise. CI further agreed that, until termination of the CI Agreement, it will (i) not sell, option, transfer or otherwise encumber the CI Shares; (ii) not solicit a competing transaction or otherwise knowingly take any action of any kind which is reasonably likely to reduce the likelihood of success of the Arrangement; (iii) not grant or agree to grant any proxy or other right to vote the CI Shares, or enter into any voting trust, vote pooling or other agreement with respect to the right to vote, call meetings of shareholders or give consents or approvals of any kind as to the CI Shares; and (iv) not do indirectly anything that CI has agreed not to do directly in the CI Agreement. Nothing in the CI Agreement will prohibit CI from selling, transferring, assigning or otherwise disposing of any CI Shares held by a mutual fund for which CI acts as a portfolio manager (i) to the extent required to fund a redemption of greater than 10% of the securities of the mutual fund by its securityholders, or (ii) after May 31, 2018, to the extent required to comply with applicable Canadian securities laws; however, in the event the sale, transfer, assignment or disposition of any CI Shares occurs after the record date for the meeting of shareholders of the Issuer to approve the Arrangement, CI will use commercially reasonable efforts to vote or cause to be voted all CI Shares in favor of the Arrangement prior to such sale, transfer, assignment or disposition.

9

Pursuant to each Voting Agreement, the Individual Shareholder party thereto agreed to vote or cause to be voted such Individual Shareholder’s shares of Common Stock beneficially owned by such Individual Shareholder (as set forth in such Individual Shareholder’s Voting Agreement): (i) in favor of the approval of the Arrangement Agreement and the transactions contemplated in the Arrangement Agreement, at every meeting of the shareholders of the Issuer at which such matters are considered and at every adjournment or postponement thereof; and (ii) against (1) any Acquisition Proposal (as defined in the Arrangement Agreement), (2) any action, proposal, transaction or agreement which could reasonably be expected to result in a breach of any covenant, representation or warranty or any other obligation or agreement of the Individual Shareholder under the Voting Agreement, and (3) any action, proposal, transaction or agreement that could reasonably be expected to impede, interfere with, delay, discourage, adversely affect or inhibit the timely consummation of the Arrangement or change in any manner the voting rights of any class of shares of the Issuer (including any amendments to the notice of articles or articles of the Issuer). Each of the Individual Shareholders agreed to grant, under certain circumstances, an irrevocable proxy appointing Parent as the Individual Shareholder’s proxy and attorney-in-fact (with full power of substitution and resubstitution) to vote such Individual Shareholder’s shares of Common Stock at any meeting of the shareholders of the Issuer called with respect to any of the matters specified in the Voting Agreements, and in accordance and consistent with the above.

Parent has also entered into separate Support Agreements each dated as of March 16, 2018 (the “Support Agreements”) with Brian Morris, Charles Oliver, John Antwi, Mark Daniel, and Michael Doolin (the “Supporting Shareholders”). Pursuant to the Support Agreements, each Supporting Shareholder has agreed not to, among other things, (i) solicit or otherwise facilitate, or enter into or otherwise engage in any substantive discussions or negotiations regarding any inquiry or proposal that constitutes or reasonably may be expected to lead to an Acquisition Proposal (as defined in the Arrangement Agreement), (ii) directly or indirectly sell, transfer, assign, grant a participation interest in, option, pledge, hypothecate, grant a security interest in or otherwise convey or encumber any of the shares of Common Stock beneficially owned by such Supporting Shareholder (“Supporting Shares”), and (iii) take any other action of any kind which would reasonably be expected to reduce the success of, or delay or interfere with the completion of, the transactions contemplated by the Arrangement Agreement. The Supporting Shareholders have further agreed that they will cooperate with the Issuer and Parent to successfully complete the Arrangement and the transactions contemplated by the Arrangement Agreement, provided that nothing in the Support Agreements shall oblige the Supporting Shareholders to provide Parent any proxy, voting instructions, power of attorney or similar instrument regarding the voting of their respective Supporting Shares in favor of the approval of the Arrangement Agreement at the special meeting of shareholders or any other meeting of the Issuer at which such matters are considered.

The description contained in this Item 4 of certain principal terms of, and the transactions contemplated by, the Shareholders Agreements is qualified in its entirety by reference to the full text of the Shareholders Agreements, the terms of each of which are incorporated herein by reference to Exhibit 3 through Exhibit 11, hereto.

Except as set forth in this Schedule 13D, the Arrangement Agreement and the Shareholders Agreements, none of the Reporting Persons have any plans or proposals which relate to or which would result in or relate to any of the actions specified in subparagraphs (a) through (j) of Item 4 of Schedule 13D of the Exchange Act.

Item 5.	Interest in Securities of the Issuer
	(a)-(b) By virtue of the Shareholders Agreements, Parent and Acquireco may be deemed to share the power to direct the vote, and may be deemed to be the beneficial owners of, 47,885,883 shares of Common Stock, representing approximately 26.3% of the outstanding shares of Common Stock (based upon a total number of 179,614,947 shares outstanding, as represented and warranted by the Issuer in the Arrangement Agreement). The Reporting Persons, however, hereby disclaim beneficial ownership of such shares, and this Schedule 13D shall not be construed as an admission that the Reporting Persons are, for any or all purposes, the beneficial owner of the securities covered by this Schedule 13D.
	(c) Except as described in this Schedule 13D, no Reporting Person and, to the best of the Reporting Persons’ knowledge, no person listed on Schedule A hereto has beneficial ownership of, or has engaged in any transaction during the past 60 days involving, any shares of Common Stock.

(e) Not applicable.
Item 6.	Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer
	The information set forth under Items 3, 4 and 5 and the agreements filed as Exhibits 2 through 16 hereto are incorporated herein by reference. Other than the Arrangement Agreement, the Shareholders Agreements and the Support Agreements described in Item 4, there are no contracts, arrangements, understandings or relationships (legal or otherwise) between the Reporting Persons and any person with respect to the securities of the Issuer, including, but not limited to, transfer or voting of any of the securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.

Dear Sirs:

Re: Proposed Arrangement with Klondex Mines Ltd.

We refer to the arrangement agreement (the “Arrangement Agreement”) proposed to be entered into between Klondex Mines Ltd. (“Klondex”), Hecla Mining Company (“Hecla”) and 1156291 B.C. Unlimited Liability Company (“Acquireco”) providing for the acquisition by Acquireco of all of the issued and outstanding common shares of Klondex (the “Arrangement”).

We represent and warrant that: (i) we beneficially own 16,933,900 common shares of Klondex (the “Affected Securities”) with good and marketable title thereto and free and clear of any encumbrances or any other rights or claims of others; and (ii) we have full power and authority to fulfill our obligations hereunder and doing so will not violate or conflict with applicable law or any agreement instrument or document to which we are party or by which we are bound.

We understand that you wish to have our agreement that we support the Arrangement and will not conduct ourselves in a manner that is inconsistent with the completion of the Arrangement. Accordingly, we agree that, during the period from the date of this letter to the Letter Termination (as hereinafter defined), we will: (i) not sell, option, transfer or otherwise encumber the Affected Securities or any interest therein; (ii) not solicit a competing transaction or otherwise knowingly take any action of any kind which is reasonably likely to reduce the likelihood of success of the Arrangement; (iii) not grant or agree to grant any proxy or other right to vote the Affected Securities, or enter into any voting trust, vote pooling or other agreement with respect to the right to vote, call meetings of securityholders or give consents or approvals of any kind as to the Affected Securities; (iv) not do indirectly anything that we have agreed not to do directly in this Agreement; and (v) deposit all of the Affected Securities, together with a duly completed and executed letter of transmittal, with the depositary specified in connection with the Arrangement in accordance with the terms thereof.

In addition, we irrevocably covenant and agree in favour of Hecla and Acquireco that, unless the Letter Termination has occurred: (i) we will vote or to cause to be voted the Affected Securities in favour of the Arrangement and all other matters related thereto including in connection with any separate vote of any sub-group of securityholders that may be required to be taken and of which sub-group we form a part; (ii) we will not exercise any rights of dissent provided under the Arrangement, any applicable laws or otherwise in connection with the Arrangement or any other corporate transaction considered at the meeting of holders of Affected Securities of Klondex in connection with the Arrangement.

Notwithstanding any other provision of this letter, our obligations hereunder shall automatically terminate (the “Letter Termination”): (i) if the Arrangement Agreement is amended without our prior written consent to reduce the amount of the consideration payable thereunder in respect of the Affected Securities; (ii) if the Arrangement Agreement is terminated for any reason; (iii) if the Outside Date (as such term is defined in the Arrangement Agreement) is extended beyond the date which is four months after the date of this letter without our prior written consent, (iv) if the directors of Klondex withdraw their approval of the Arrangement or approve or recommend any Competing Proposal (as defined in the Arrangement Agreement) in respect of Klondex in a manner that complies with the Arrangement Agreement, or (v) if the representations and warranties of each of Hecla and Acquireco as set forth in the Arrangement Agreement are not true and correct or Hecla or Acquireco have not complied with all of their covenants to Klondex contained in the Arrangement Agreement and such non-compliance has not been cured within five business days after receipt of written notice of such non-compliance, delivered by us or Klondex.

We confirm that this letter agreement constitutes our legal, valid and binding obligation and is enforceable against us in accordance with its terms. We also recognize and acknowledge that this Agreement is an integral part of the transactions contemplated in the Arrangement Agreement, that Hecla and Acquireco will not enter into the Arrangement Agreement unless this Agreement is executed, and accordingly acknowledge and agree that a breach by us of any covenants or other commitments contained in this Agreement will cause Hecla and Acquireco to sustain injury for which they would not have an adequate remedy at law for money damages. Therefore, we agree that in the event of any such breach, you shall be entitled to the remedy of specific performance of such covenants or commitments and preliminary and permanent injunctive and other equitable relief in addition to any other remedy to which you may be entitled, at law or in equity and further agree to waive any requirement for the securing or posting of any bond in connection with the obtaining of any such injunctive or equitable relief.

This Agreement shall be governed by and construed in accordance with the laws of the Province of British Columbia and the federal laws of Canada applicable therein.

We look forward to the successful completion of the Arrangement.

Yours truly,

Sentry Investments Inc.

Notwithstanding the foregoing, nothing in this letter agreement shall in any way prohibit us from selling, transferring, assigning or otherwise disposing of any of the Affected Securities held by a mutual fund for which we act as portfolio manager: (i) to the extent required to fund a redemption of greater than 10% of the securities of the mutual fund by its securityholders, or (ii) after May 31, 2018, to the extent required to comply with applicable Canadian securities laws governing an investment’s fund’s ownership of securities provided that in the event of any such sale, transfer, assignment or disposition that occurs after the record date for the meeting of shareholders of Klondex called to approve the Arrangement, we will use commercially reasonable efforts to vote or cause to be voted all Affected Securities in favour of the Arrangement prior to completion of such sale, transfer, assignment or disposition.

In addition, we irrevocably covenant and agree in favour of Hecla and Acquireco that, unless the Letter Termination has occurred: (i) we will vote or to cause to be voted the Affected Securities in favour of the Arrangement and all other matters related thereto including in connection with any separate vote of any sub-group of securityholders that may be required to be taken and of which sub-group we form a part; (ii) we will not exercise any rights of dissent provided under the Arrangement, any applicable laws or otherwise in connection with the Arrangement or any other corporate transaction considered at the meeting of holders of Affected Securities of Klondex in connection with the Arrangement.

2

(c) subject to Section 5.1, the Shareholder shall not, directly or indirectly, through any officer, director, employee, representative, agent or otherwise, and shall not permit any such person to:

2

(c) subject to Section 5.1, the Shareholder shall not, directly or indirectly, through any officer, director, employee, representative, agent or otherwise, and shall not permit any such person to:

(i) solicit, assist, initiate, knowingly encourage or otherwise facilitate (including by way of furnishing or providing copies of, access to, or disclosure of, any confidential information, properties, facilities, books or records of the Company or entering into any form of agreement, arrangement or understanding) any inquiry, proposal or offer that constitutes or may reasonably be expected to constitute or lead to, an Acquisition Proposal;

3

(f) subject to Section 5.1, the Shareholder shall not take any other action of any kind, directly or indirectly, which would reasonably be expected to reduce the success of, or delay or interfere with the completion of the transactions contemplated by the Arrangement Agreement, unless otherwise directed in writing by the Purchaser;

2

(c) subject to Section 5.1, the Shareholder shall not, directly or indirectly, through any officer, director, employee, representative, agent or otherwise, and shall not permit any such person to:

(i) solicit, assist, initiate, knowingly encourage or otherwise facilitate (including by way of furnishing or providing copies of, access to, or disclosure of, any confidential information, properties, facilities, books or records of the Company or entering into any form of agreement, arrangement or understanding) any inquiry, proposal or offer that constitutes or may reasonably be expected to constitute or lead to, an Acquisition Proposal;
