COEUR D'ALENE, Idaho, July 13, 2021–(BUSINESS WIRE)–Hecla Mining Company (NYSE:HL) today announced its preliminary silver and gold production for the second quarter of 2021.¹

HIGHLIGHTS

• Silver production of 3.5 million ounces, an increase of 4% due to full production at Lucky Friday.

• Gold production of 59,139 ounces, a decrease of 1%.

• Zinc production decreased 4% due to lower grades at Greens Creek and lead production increased 29% due to Lucky Friday production.

• Production of all metals was higher than the first quarter of 2021.

• Silver equivalent production of 10.1 million ounces or gold equivalent production of 148,161 ounces.²

• Quarter-end cash position of approximately $181 million.

"With steady growth in silver production at the Lucky Friday Mine and solid operating performance from our Greens Creek Mine, we achieved our second highest quarterly silver production since 2016," said Hecla’s President and CEO, Phillips S. Baker, Jr. "This strong performance combined with steady prices delivered an increase of approximately $41 million in cash, the fifth consecutive quarter of increasing cash reserves and one of the highest increases in Hecla’s history. With the Company’s U.S. vaccination rate higher than the U.S. average including Greens Creek at a nearly 90% vaccination rate, and Casa Berardi vaccinations increasing, we expect to build on these results."

OPERATIONS

Greens Creek

At the Greens Creek Mine, 2.6 million ounces of silver and 12,859 ounces of gold were produced. The decrease in silver production compared to the second quarter of 2020 was due to lower grades resulting from mine sequencing. The mill operated at an average of 2,362 tons per day (tpd).

Casa Berardi

At the Casa Berardi Mine, 31,332 ounces of gold were produced. The increase in gold ounces compared to the second quarter of 2020 was due to higher mill throughput, partially offset by lower grades. The mill operated at an average of 4,117 tpd.

Lucky Friday

At the Lucky Friday Mine, 913,294 ounces of silver were produced in the quarter, an increase of 95% compared to the second quarter of 2020 due to the return to full production in the fourth quarter of 2020. The mill operated at an average of 906 tpd.

Nevada Operations

At the Nevada operations, 14,947 ounces of gold and 45,125 ounces of silver were produced from processing previously stockpiled ore, including oxide material processed at the Midas mill and a bulk sample of refractory material processed at a third-party facility.

In the second half of 2021, approximately 10,000 tons of refractory material is expected to be processed as a test at a third-party autoclave facility.
