        <footnote id="F1">Mr. McDonald was awarded (I) 68,182 restricted stock units on June 7, 2016, (ii) 51,107 restricted stock units on June 7, 2017, and (iii) 65,274 restricted stock units on June 29, 2018.  The restrictions lapsed on 1/3 of those vesting units (61,521 shares).  Mr. McDonald elected to have Hecla Mining Company withhold 32,832 shares to cover his tax liability.</footnote>
        <footnote id="F2">Award of restricted stock units that vest as follows: 36,232 shares on June 21, 2020; 36,232 shares on June 21, 2021; and 36,232 shares on June 21, 2022.</footnote>
        <footnote id="F3">Total number of unvested restricted stock units held by Mr. McDonald</footnote>
        <footnote id="F4">Mr. McDonald was awarded performance rights representing the contingent right to receive between $62,500 and $250,000 worth of Hecla Mining Company common stock based on Hecla Mining Company's Total Shareholder Return performance over the 3-year period (January 1, 1019 to December 21, 2021) relative to our peers.  Examples of the potential grant of shares to Mr. McDonald under this plan are as follows: 100th percentile rank among peers = maximum award at 200% target ($250,000 in stock); 60th percentile rank among peers = target award at grant value ($125,000 in stock); and 50th percentile rank among peers = threshold award at 50% of target ($62,500 in stock).</footnote>
        <footnote id="F5">The number shown in Column 5 of Table II assumes a target payout (i.e., $125,000 worth of common stock), with the common stock valued at the closing price on the day of the award ($1.84).  the actual number of shares received (if any) by Mr. McDonald will depend on the Total Shareholder Return performance over the 3-year period and will be determined following the termination of that period.</footnote>
        <footnote id="F6">Total consists of 601,527 shares held directly, 169,248 unvested restricted stock units, and 115,507 performance-based shares.</footnote>
