Common Stock Dividends

On February 21, 2022, our Board of Directors declared a quarterly cash dividend of $0.00625 per share of common stock, consisting of $0.00375 per share for the minimum dividend component of our common stock dividend policy and $0.0025 per share for the silver-linked dividend component of the policy, for a total dividend of $3.4 million paid in March 2022. The realized silver price of $23.49 in the fourth quarter of 2021 satisfied the criterion for the silver-linked dividend component of our common stock dividend policy.
