NEWS RELEASE

HECLA IS RESTARTING CASA BERARDI

FOR IMMEDIATE RELEASE

April 14, 2020

COEUR D'ALENE, IDAHO -- Hecla Mining Company (NYSE:HL) today announced that Casa Berardi plans to restart operations on April 15^th, following the Government of Quebec’s decision to allow mining activities to resume.

The restart of operations is planned over a month and will follow the Government’s guidelines with a focus on maintaining appropriate COVID-19 practices, including emphasizing proper hygiene practices and social distancing. As an added precaution, open pit contract mining will not yet resume to minimize the number of workers on site. Stockpiled open pit ore will be fed to the mill until contract mining resumes.

“We are pleased to bring the mine back into production, with the emphasis on the health and safety of our people,” said Phillips S. Baker, Jr., Hecla’s President and CEO. “We continue to have no known cases of COVID-19 at any of our operations in part due to our early adoption of measures that protect our workforce and their communities.”

When a forward-looking statement expresses or implies an expectation or belief as to future events or results, such expectation or belief is expressed in good faith and believed to have a reasonable basis.

The material factors or assumptions used to develop such forward-looking statements or forward-looking information include that the Company’s plans for development and production will proceed as expected and will not require revision as a result of risks or uncertainties, whether known, unknown or unanticipated, to which the Company’s operations are subject.

Estimates or expectations of future events or results are based upon certain assumptions, which may prove to be incorrect, which could cause actual results to differ from forward-looking statements.
