### Footnotes:

(1) On June 22, 2020, Mr. Sienko was awarded performance rights.  The performance rights represented a contingent right to receive between $50,000 and $200,000 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., $200,000 worth of common stock); (2) 60th percentile rank among peers = target award at grant value (i.e., $100,000 worth of common stock); or (3) 50th percentile rank among peers = threshold payout at 50% target (i.e., $50,000 worth of common stock).

(2) In reporting the number of performance rights at the time of the award, Mr. Sienko assumed a target payout (i.e. $100,000 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 33,003 performance rights.  Based on Hecla Mining Company's total shareholder return ranking, Mr. Sienko's award value was $200,000, and he therefore received 66,006 shares in settlement of the award (with the shares valued at the $3.03 closing price on June 22, 2020.

(3) Consists of outstanding performance rights.

(4) See footnotes (1) and (2).  Shares received upon settlement of performance rights awarded in June 2020.

(6) Shares withheld for tax liability on 66,006 performance rights that vested.
