Hecla Mining Company ( NYSE:HL) today announced preliminary production results¹ for the second quarter 2015 and updated annual production estimations.

HIGHLIGHTS (quarterly comparisons to Q2 2014)
  • Estimated company-wide silver production for 2015 increased to 10.5-11.0 million ounces from 10.5 million ounces.
  • Silver production of 2.48 million ounces, a 2% decrease.
  • Gold production of 44,692 ounces, a 3% increase.
  • Silver equivalent production of 8.7 million ounces, the same as Q2 2014. 2
  • Lead production decreased 7% to 9,525 tons and zinc production increased 1% to 17,516 tons.
  • Cash and cash equivalents of approximately $190 million as of June 30, 2015.
  • Hecla has secured the third party-owned Velardeña mill to process ore from its high-grade San Sebastian project in Mexico.

"Higher grades and recoveries at Greens Creek during the quarter continued to improve the mine's already strong performance," said Phillips S. Baker, Jr., Hecla's President and CEO. "For a mine producing over 7 million ounces of silver a year, an 8% increase in silver recovery is a significant value driver, especially when coupled with the higher grades. We expect these recoveries and grades to continue at Greens Creek through the remainder of the year."

Greens Creek

Greens Creek's second quarter production of 1,856,125 million ounces of silver exceeded the second quarter of 2014 by 10%, while gold production of 13,753 ounces was 8% lower. The higher silver production was a result of higher recoveries and grade, partially offset by slightly lower tonnage. Silver recoveries increased 8%, or 5.6 percentage points, to 75.4% over the prior year period due to changes in the fourth quarter modifying the flotation circuit to more efficiently scalp additional lead concentrate directly to final concentrate, and by introducing CO 2 for pH control in the lead flotation circuit in April 2015. The reduction in gold production was the result of lower tonnage and grade partially offset by recoveries that increased due to the previously described plant improvements. The mill operated at an average of 2,194 tons per day (tpd) in the second quarter.

(2) Silver equivalent calculations based on the following prices: $17.25 for Ag, $1,225 for Au, $0.90 for Pb, and $1.00 for Zn.

As a result of higher grades and recoveries, the Company now expects Greens Creek to produce 7.7 to 8.0 million ounces of silver, an increase over the previous expectation of 7.3 million ounces.
  Second Quarter Ended
    June 30, 2015   June 30, 2014
Greens Creek Recovery        
Silver 75.4%   69.8%
Gold 64.7% 62.9%
Lead 80.4% 77.1%
Zinc 86.7% 88.7%

Lucky Friday

Lucky Friday's second quarter silver production of 613,474 ounces was 25% lower than the second quarter of 2014 due to lower tonnage and grade. A failure of the underground booster fan reduced the ventilation capacity of the mine, leading to the temporary closure of a higher-grade production stope. Lucky Friday has returned to normal production rates by extending the work schedule to seven days per week from six, but is mining lower grade material until the fan is replaced, expected in the fourth quarter. In addition, there are 10 days of scheduled downtime in the third quarter for hoist mechanical maintenance. The mill operated at an average of 792 tpd in the second quarter.

The mine is now expected to produce 2.8 to 3.0 million ounces of silver in 2015, a reduction over the previous estimate of 3.2 million ounces.

Casa Berardi

Casa Berardi's second quarter gold production of 30,939 ounces was 8% higher than the second quarter of 2014 because of higher grades, partially offset by lower tonnage and recovery. The mine experienced higher grades as a result of mine sequencing. While recoveries relative to a year ago decreased to 86% from 90% due to the presence of arsenopyrite in some of the 118 Zone ore, adjustments made to the plant in 2015 are expected to contribute to recoveries increasing to 87% during the second half of the year. The mill operated at an average of 2,407 tpd in the second quarter.

With expectations for additional recovery improvements, and the planned addition of a high-grade stope in Zone 123 in the fourth quarter, the mine is expected to meet its 130,000 gold ounce target for the year.

San Sebastian

Minera Hecla, S.A. de C.V., a wholly owned subsidiary of Hecla Mining Company has entered into a lease agreement with Minera William S.A. de C.V., a wholly owned subsidiary of Golden Minerals Company and owner of the Velardeña oxide mill in Durango State, Mexico. Under the terms of the agreement, Hecla has exclusive use of the mill for 18 months, with the potential to increase for up to another 12 months. Located within 100 miles of San Sebastian, the mill was previously used by Hecla to process ore when it mined on the property from 2001 to 2005.
