        <footnote id="F1">On June 22, 2020, Mr. Roberts was awarded performance rights.  The performance rights represented a contingent right to receive between $75,000 and $300,000 worth of Hecla Mining Company common stock based on Hecla's total shareholder return performance over the 3-year period from January 1, 2020 through December 31, 2022, based on the following percentile rank within Hecla's peer group companies:  (1) 100th percentile rank among peers = maximum award at 200% of target (i.e., $300,000 worth of common stock); (2) 60th percentile rank among peers = target award at grant value (i.e., $150,000 worth of common stock); or (3) 50th percentile rank among peers = threshold payout at 50% of target (i.e., $75,000 worth of common stock).</footnote>
        <footnote id="F2">In reporting the number of performance rights at the time of the award, Mr. Roberts assumed a target payout (i.e., $150,000 worth of common stock), with the common stock valued at the closing price on the day of the award ($3.03), and therefore reported an award of 49,505 performance rights.  Based on Hecla Mining Company's total shareholder return ranking, Mr. Robert's award value was $300,000, and he therefore received 99,010 shares in settlement of the award (with the shares valued at the $3.03 closing price on June 22, 2020).</footnote>
        <footnote id="F3">Consists of outstanding performance rights.</footnote>
        <footnote id="F4">See footnotes (1) and (2).  Shares received upon settlement of performance rights awarded in June 2020.</footnote>
        <footnote id="F5">Consists of 346,515 shares held directly, 339,119 shares held in the Key Employee Deferred Compensation Plan, and 111,328 unvested restricted stock units.</footnote>
        <footnote id="F6">Shares withheld for tax liability on the 99,010 performance rights that vested.</footnote>
        <footnote id="F7">Consists of 317,717 shares held directly, 339,119 shares held in the Key Employee Deferred Compensation Plan, and 111,328 unvested restricted stock units.</footnote>
        <footnote id="F8">Held as 703.724 units in Mr. Robert's 401(k) account under the Hecla Mining Company Capital Accumulation Plan, and estimated to be 8,444 shares.</footnote>
