Hecla Reports 2.9 Million Ounces of Silver and 60,021 Ounces of Gold Production in First Quarter 2019

Hecla Mining Company (NYSE:HL) today announced preliminary silver and gold production results for the first quarter of 2019.¹

HIGHLIGHTS

• Silver production of 2.9 million ounces, and gold production of 60,021 ounces.
• Silver equivalent production of 10.8 million ounces or gold equivalent production of 129,378 ounces.²
• Lead production of 5,785 tons; zinc production of 13,943 tons.
• Cash, cash equivalents and short-term investments of approximately $12 million at March 31, 2019.

“Silver production was higher in the quarter due to the standout performance from our most important mine, Greens Creek, with higher gold and silver grades and recoveries than the first quarter of 2018,” said Phillips S. Baker, Jr., Hecla’s President and CEO. “As we indicated with our technical report we expected higher grades at Greens Creek. The Lucky Friday also contributed with more silver production in the quarter than was achieved all of last year. San Sebastian production was about the same as last year’s fourth quarter. Quarterly gold production was higher than last year, but we expect significant production increases from Casa and the Nevada assets in the second half of the year.”

“With the recent decline in interest rates, one of our priorities over the next year is to extend the maturity of our high yield notes,” Mr. Baker added.

Greens Creek

At the Greens Creek mine, 2.2 million ounces of silver and 14,328 ounces of gold were produced. Higher silver and gold production, when compared to the first quarter of 2018, was due to higher ore grades as well as increased recoveries, partially offset by lower mill throughput. The mill operated at an average of 2,298 tons per day (tpd).

Casa Berardi

At the Casa Berardi mine, 31,799 ounces of gold were produced, including 6,535,ounces from the East Mine Crown Pillar pit, with the decrease compared to the first quarter of 2018 due to lower ore tonnage, recovery and grades. Tonnage was affected by the December 2018 replacement of the crusher with a higher-capacity crusher. Subsequent sizing issues required planned adjustments in the first quarter to a number of mill components, which impacted the throughput. With the excess mined material in stockpile, the ounces should be recovered during the rest of the year. Recoveries were impacted principally by the loss of a CIL tank drivetrain, and a new drivetrain is expected to be installed by early May. Mined grades underground were 9 percent higher than projected. The mill operated at an average of 3,664 tpd.

San Sebastian

At the San Sebastian mine, 0.4 million ounces of silver and 3,530 ounces of gold were produced with the decrease due to the expected lower grades. The mill operated at an average of 494 tpd.

A review of sulfide ore continues, including a bulk sample to test the capabilities of the third-party plant and the suitability of long-hole stoping for the ore body, with results expected by the fourth quarter of 2019.

Nevada Operations

At the Nevada operations, 10,364 ounces of gold and 67,438 ounces of silver were produced. During the quarter, the focus continued on establishing a robust development program in a variety of ground conditions at Fire Creek and Hollister, rather than on production which is expected to be second half-weighted this year. A minor amendment to the water discharge permit for Fire Creek is expected in the second quarter which should enable a higher discharge rate. In addition, changes to the carbon circuit of the Midas mill are expected to improve recoveries. Ore was processed at an average of 460 tpd (combined Midas and Aurora mills).

Lucky Friday

At the Lucky Friday mine, 173,627 ounces of silver were produced, a 74% increase over Q1 2018. As a result of the ongoing strike by unionized employees, there was limited production and capital improvements, performed by salaried staff, and limited shipments of concentrate in the first quarter.
