         Ladies and Gentlemen:

                   Hecla Mining Company ("Hecla") has advised Muzinich &
         Co., Inc. ("Muzinich") that Hecla wishes to retain Muzinich to
         provide services to Hecla as placement agent in connection with
         the sale (the "Offering") of not less than 3,200,000 shares and
         not more than 4,500,000 shares of Hecla's common stock, par
         value $.25 per share (the "Common Stock").

                   The purpose of this letter agreement (this "Agree-
         ment") is to confirm the engagement of Muzinich by Hecla in
         connection with the Offering.

                   Section 1.  Engagement of Muzinich in connection with
         Proposed Offering.  Hecla hereby retains Muzinich, and Muzinich
         hereby agrees to act as placement agent for Hecla, and agrees
         to use its best efforts to sell, not less than 3,200,000 shares
         and not more than 4,500,000 shares of the Common Stock (the
         "Shares"), for the highest possible price per share, with the
         price to be received by Hecla being adjusted to reflect market
         conditions providing for a discount to the closing price of the
         Common Stock on the date of the closing of the Offering, and to
         perform all other services as is customary for a placement
         agent and which are necessary to consummate the transactions
         contemplated by this Agreement.  The final price per share is
         subject to the approval of Hecla in its sole discretion.  The
         Shares will be registered with the Securities and Exchange Com-
         mission pursuant to the Securities Act of 1933, as amended,
         pursuant to Hecla's currently effective shelf registration
         statement.


                                                                      2




                   Section 2.  Compensation.  As compensation for
         Muzinich's services in connection with the issuance of the
         Shares, Hecla shall pay Muzinich the following fees upon re-
         ceipt of the proceeds from such sale:

                   (a)  a placement fee of 4.3% of the gross proceeds
                        received by Hecla from the issuance of the
                        Shares, payable upon receipt of the proceeds
                        from such sale, and all reasonable legal fees
                        and expenses incurred by Muzinich (with such
                        fees and expenses in excess of $20,000 being
                        pre-approved by Hecla); and

                   (b)  if Hecla terminates this Agreement prior to the
                        closing of the Offering and, at the time of such
                        termination, Muzinich is not in breach in any
                        material respect of any of its obligations under
                        this Agreement, a fee of 0.50% of the funds
                        theretofore committed by investors pursuant to
                        written subscription agreements and all reason-
                        able out-of-pocket expenses (including reason-
                        able legal fees and expenses) incurred by
                        Muzinich in connection with the Offering (with
                        such fees and expenses in excess of $20,000
                        being pre-approved by Hecla).

                   Section 3.  Other Agreements.

                   (a)  Term.  Muzinich's engagement hereunder may be
                        terminated by Muzinich at any time or, after the
                        date which is 20 days from the execution of this
                        letter, by Hecla, by prior written notice there-
                        of to other party; provided, however, that the
                        provisions of Sections 2(b), 3(c), 3(d) and 3(f)
                        shall survive such termination.

                   (b)  Information.  During the term of this Agreement,
                        Hecla agrees to furnish Muzinich with such in-
                        formation about Hecla as Muzinich reasonably
                        requests ("Company Information").  Hecla repre-
                        sents and warrants to Muzinich that all Company
                        Information will be accurate in all material
                        respects at the time it is furnished and will
                        not contain any untrue statement of a material
                        fact or omit to state a material fact necessary
                        in order to make the statements therein not mis-
                        leading in 


                                                                       3




                        light of the circumstances under which such
                        statements are made, and agrees to advise
                        Muzinich prior to the sale of any shares of all
                        developments materially affecting Hecla,
                        or the accuracy of Company Information previ-
                        ously furnished to Muzinich or prospective pur-
                        chasers of the Shares.  Hecla recognizes and
                        confirms that Muzinich (i) will be relying sole-
                        ly on such information and other information
                        available from generally recognized public
                        sources in performing the services contemplated
                        hereunder, (ii) will not independently verify
                        the accuracy or completeness of such informa-
                        tion, (iii) does not assume responsibility for
                        the accuracy or completeness thereof, and (iv)
                        will make appropriate disclaimers consistent
                        with the foregoing.  In addition, any written
                        representations and warranties made by Hecla to
                        purchasers of the Shares shall be deemed to be
                        incorporated into this Agreement.

                   (c)  Indemnification.  Hecla agrees to indemnify
                        Muzinich and its affiliates and each person in
                        control of Muzinich and its affiliates and their
                        respective officers, directors, employees,
                        agents and representatives as provided in the
                        indemnity letter dated the date hereof and
                        attached hereto.

                   (d)  No Shareholder Rights.  Hecla acknowledges and
                        agrees that Muzinich has been retained only by
                        Hecla and that Hecla's engagement of Muzinich is
                        not deemed to be on behalf of and is not in-
                        tended to confer rights upon any shareholder,
                        owner or partner of Hecla or any other person
                        not a party hereto as against Muzinich or any of
                        its affiliates or the directors, officers, em-
                        ployees, agents and representatives of Muzinich.
                        Unless otherwise expressly agreed, no one other
                        than Hecla is authorized to rely upon Hecla's
                        engagement of Muzinich or any statements, advice
                        or opinions by Muzinich to Hecla.

                   (e)  Miscellaneous.  This Agreement may be executed
                        in two or more counterparts, all of which to-
                        gether shall be considered a single instrument.
                        The term "affiliate" as used herein shall have
                        the meaning ascribed to 

                                                                        4





                        such term in the rules and regulations
                        promulgated under the Securities Exchange Act of
                        1934, as amended.  Hecla confirms that it will
                        rely on its own counsel, accountants and other
                        similar expert advisors for legal, accounting,
                        tax and other similar expert advice.  This
                        Agreement and the indemnity letter of even date
                        herewith constitute the entire agreement between
                        the parties with respect to the subject matter
                        hereof and supersede all other prior agreements
                        and understandings, both written and oral,
                        between the parties hereto with respect to the
                        subject matter hereof and cannot be amended or
                        otherwise modified except in writing executed by
                        the parties hereto.  The provisions hereof shall
                        inure to the benefit of and be binding upon the
                        successors and permitted assignees of Hecla and
                        Muzinich.  This letter is not intended to be and
                        should not be construed as a commitment with
                        respect to the underwriting, sale or placement
                        of the Shares and, except as expressly set forth
                        herein, creates no obligation or liability on
                        the part of Muzinich in connection therewith.

                   (f)  Confidentiality.  Except as required by law and
                        except with respect to any information that
                        otherwise becomes publicly available other than
                        as a result of a breach of this clause (f),
                        Muzinich agrees that it and its officers, em-
                        ployees, affiliates and agents will treat confi-
                        dentially and take reasonable precautions to
                        preserve and protect the confidentiality of and
                        otherwise refrain from disclosing to any person
                        other than officers, employees, affiliates and
                        agents of Muzinich any and all information fur-
                        nished to Muzinich pursuant to the terms of this
                        Agreement and consistent with industry practices
                        and will not use any of such information for any
                        purpose other than as set forth herein.  In the
                        event that disclosure by Muzinich of any such
                        information is required by law, Muzinich shall,
                        if reasonably practicable, notify Hecla of such
                        requirement prior to disclosing any information
                        thereunder, and, in any event, shall notify
                        Hecla promptly after such disclosure.  Muzinich
                        will not provide any information to prospective
                        investors other than publicly available informa-
                        tion.

                                                                         5





                   (g)  Use of Name; Disclosure; Muzinich Advice, Role,
                        etc.  Hecla agrees that any references to
                        Muzinich made in connection with the Offering
                        are subject to Muzinich's prior approval, which
                        approval shall not be unreasonably withheld or
                        delayed.  Hecla acknowledges that all analyses,
                        evaluations and advice (whether written or oral,
                        formal or informal) given by Muzinich to Hecla
                        in connection with its engagement hereunder are
                        intended solely for the benefit and use of Hecla
                        (including its management, directors and attor-
                        neys) in considering the transaction to which
                        they relate and Hecla agrees that no such opin-
                        ion or advice shall be used for any other pur-
                        pose or reproduced, disseminated, quoted or
                        referred to at any time, in any manner or for
                        any purpose, without Hecla's prior written con-
                        sent, which shall not be unreasonably withheld
                        or delayed.  Muzinich is authorized upon consum-
                        mation of the Offering contemplated hereby to
                        place the customary "tombstone" advertisement in
                        publications of its choice at Muzinich's ex-
                        pense.  Nothing in this Agreement is intended to
                        obligate or commit Muzinich to provide any ser-
                        vices other than as set out herein.  

                   (h)  GOVERNING LAW, ETC.  THIS AGREEMENT SHALL BE
                        GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
