Explanation of Responses:

( 1 )In June 2023, Mr. Allen was awarded performance rights representing the contingent right to receive between $55,000 and $220,000 worth of Hecla Mining Company common stock based on Hecla Mining Company's Total Shareholder Return over the 3-year period (January 1, 2023 to December 31, 2025), based on the following percentile rank within Hecla's peer group companies: 100th percentile rank among peers = maximum award at 200% of target ($220,000 in stock); 40th to 60th percentile rank among peers = target award at grant value ($110,000 in stock); and 25th percentile rank among peers = threshold award at 50% of target ($55,000 in stock). ( 2 )In reporting the number of performance rights at the time of the award, Mr. Allen assumed a target (i.e., $110,000 in stock), with the common stock valued at the closing price on the day of the award ($5.05), and therefore reported an award of 21,782 performance rights. Based on Hecla Mining Company's total shareholder return ranking, Mr. Allen's award value was 100% and he therefore received 21,782 shares in settlement of the award (with the shares valued at the $5.05 closing price on June 21, 2023). ( 3 )Consists of outstanding performance rights. ( 4 )See footnotes (1) and (2). Shares received upon settlement of performance rights awarded in June 2023.
