Second highest silver production in Hecla’s history

COEUR D'ALENE, Idaho--(BUSINESS WIRE)-- Hecla Mining Company (NYSE:HL) today announced its preliminary silver and gold production for the fourth quarter and full year 2020 and year-end cash position.1

HIGHLIGHTS
• Silver production of 13.5 million ounces, an increase of 7%, second highest production only to 2016.
• Gold production of 208,962 ounces, expected lower gold production from the Nevada operation decreased production 23% from 2019, which was Hecla’s highest gold production.
• Zinc and lead production increased 7% and 41%, respectively, due to the ramp up of the Lucky Friday Mine.
• Silver equivalent production of 40.7 million ounces and gold equivalent production of 471,413 ounces.2
• Year-end cash position of $131 million with the credit facility undrawn.
• Net debt reduction of approximately $75 million, or 16%, from March 31, 2020.3
• All injury frequency rate (AIFR) of 1.22 for 2020, lowest in the Company’s history and a reduction of 24% over 2019.

“Despite the challenges of operating during the pandemic, 2020 marked a year of very strong operational performance with silver production significantly exceeding guidance,” said Hecla’s President and CEO, Phillips S. Baker, Jr. “Our U.S. silver production was 15% higher than the year before and more than 50% higher than 2018, strengthening our position as the United States largest silver producer. The strong performance allowed Hecla to reduce net debt, increase dividends, and double exploration expenditures while more than doubling last year’s cash position. At current prices, we could repeat these results in 2021.”

Greens Creek

At the Greens Creek Mine in 2020, 10.5 million ounces of silver and 48,490 ounces of gold were produced. For the fourth quarter, 2.3 million ounces of silver and 10,276 ounces of gold were produced. The mill operated at an average of 2,236 tons per day (tpd) in 2020. Fourth quarter production was affected by a significant weather event in December when southeast Alaska was impacted by historically high winds and heavy rains that caused heavy damage in the area and communities. Mr. Baker commended the team at Greens Creek for the management of this weather event and noted, “The preparation and response to this event is a testament to the excellent team at Greens Creek and their commitment to safety and the environment.”

Casa Berardi

At the Casa Berardi Mine, 121,493 and 37,580 ounces of gold were produced in 2020 and the fourth quarter, respectively. The latter represents an increase of 11,175 ounces over the third quarter due to more tons milled and higher grades. The mill operated at an average of 3,699 tpd in 2020. Overall, 2020 gold production decreased by 10%, or 12,916 ounces, compared to 2019, primarily due to the three-week suspension of operations at the mine to comply with the Government of Quebec’s COVID?19 order in April, and downtime for planned major mill repairs in the third quarter.

Mining was completed in the third quarter and milling completed in the fourth quarter of 2020. The mill operated at an average of 474 tpd when in production. The Company continues to explore this highly prospective land package and will evaluate further mining based on exploration results.

Nevada Operations

At the Nevada operations in 2020, 31,756 ounces of gold and 37,443 ounces of silver were produced. Ore mined during the third and fourth quarters was stockpiled for expected processing in early 2021. Mining of non-refractory ore is substantially complete. Mining of refractory ore for the bulk sample test continued through the fourth quarter of 2020. Production from this test is expected to be in the range of five thousand ounces of gold in the first half of 2021.
