Hecla Reports Third Quarter Production Results

Hecla Mining Company (NYSE:HL) today announced preliminary production results¹ for the third quarter 2015.

HIGHLIGHTS

• Silver production of 2,591,546 ounces.
• Gold production of 43,635 ounces.
• Silver equivalent production of 8.7 million ounces.2
• Zinc production of 17,435 tons and lead production of 9,123 tons.
• Production decision made at San Sebastian project in Mexico and stripping on the Middle Vein has begun.
• Year-end production expected to be at the high end of the previous estimate of 10.5-11.0 million ounces of silver and 185,000 ounces of gold. Gold production is now expected to be 59,000 ounces at Greens Creek and 126,000 ounces at Casa Berardi.

“Greens Creek continues to drive Hecla’s strong, consistent production performance,” said Phillips S. Baker, Jr., Hecla’s President and CEO. “We expect a considerably stronger fourth quarter, now that the ventilation system has restarted at Lucky Friday and with higher-grade material from the 123 Zone at Casa Berardi. When coupled with the startup of San Sebastian which is underway, we are optimistic about our performance going into 2016.”

(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.

Greens Creek

Greens Creek’s third quarter production of 1,992,037 ounces of silver exceeded the third quarter of 2014 by 5.3%, while gold production of 14,376 ounces was 6.3% higher. The higher silver production was a result of higher recoveries and tonnage, partially offset by slightly lower grades. The mill operated at an average of 2,233 tons per day (tpd).

Lucky Friday

Lucky Friday’s third quarter silver production of 592,243 ounces was 39% lower than the third quarter of 2014 due to lower tonnage and grade. A failure of the underground booster reduced the ventilation capacity of the mine, leading to the temporary closure of a higher-grade production stope. Replacement fans are now in operation and Lucky Friday has returned to normal production. In addition, there were 16 days of downtime in the third quarter for planned hoist mechanical maintenance. The mill operated at an average of 715 tpd.

Casa Berardi

Casa Berardi’s third quarter gold production of 29,259 ounces was in line with the third quarter of 2014. The mill operated at an average of 2,262 tpd.

San Sebastian

San Sebastian’s high-grade near-surface material is projected to produce 8.1 million silver equivalent ounces with after-tax cash flow (5% discount rate) of $43 million over its mine life. The Company’s approach at San Sebastian is to minimize capital expenditures ($5.8 million) by using a mining contractor and renting capacity from a nearby mill, which should allow the project to quickly move into production despite the low-price environment.1 This approach reflects the Company’s strategy of seeking to simultaneously grow and create value while maintaining a healthy balance sheet.

The mining contractor has begun stripping on the Middle Vein. The Company expects to be processing ore by year end, and to continue for 18 months, a period that may be extended with additional resources as a result of continued in-fill and exploration drilling.

Production Results

(1) The production, capital and cash flow estimates are derived from the preliminary economic assessment (PEA) that is underway. The PEA is preliminary in nature, and is based on a mineral resource estimate that includes inferred mineral resources (approximately 10% of projected production) that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Results quoted assume $1,103/oz gold and $15.53/oz silver prices and a 12.5 Peso/Dollar exchange rate. The PEA is expected to be completed by the end of October and the Company does not expect any changes in the PEA to materially affect the potential viability of the project.

Hecla expects to report third quarter financial results on November 4, 2015.

Cautionary Statements to Investors on Reserves and Resources

Reporting requirements in the United States for disclosure of mineral properties are governed by the SEC and included in the SEC's Securities Act Industry Guide 7, entitled “Description of Property by Issuers Engaged or to be Engaged in Significant Mining Operations” (“Guide 7”). However, the Company is also a "reporting issuer" under Canadian securities laws, which require estimates of mineral resources and reserves to be prepared in accordance with Canadian National Instrument 43-101 (“NI 43-101”). NI 43-101 requires all disclosure of estimates of potential mineral resources and reserves to be disclosed in accordance with its requirements. Such Canadian information is being included here to satisfy the Company's “public disclosure” obligations under Regulation FD of the SEC and to provide U.S. holders with ready access to information publicly available in Canada.

Reporting requirements in the United States for disclosure of mineral properties under Guide 7 and the requirements in Canada under NI 43-101 standards are substantially different. This document contains a summary of certain estimates of the Company, not only of proven and probable reserves within the meaning of Guide 7, which requires the preparation of a “final” or “bankable” feasibility study demonstrating the economic feasibility of mining and processing the mineralization using the three-year historical average price for any reserve or cash flow analysis to designate reserves and that the primary environmental analysis or report be filed with the appropriate governmental authority, but also of mineral resource and mineral reserve estimates estimated in accordance with the definitional standards of the Canadian Institute of Mining, Metallurgy and Petroleum referred to in NI 43-101. The terms “measured resources”, "indicated resources," and "inferred resources" are Canadian mining terms as defined in accordance with NI 43-101. These terms are not defined under Guide 7 and are not normally permitted to be used in reports and registration statements filed with the SEC in the United States, except where required to be disclosed by foreign law. Investors are cautioned not to assume that any part or all of the mineral deposits in such categories will ever be converted into proven or probable reserves. “Resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of such a "resource” will ever be upgraded to a higher category or will ever be economically extracted. Investors are cautioned not to assume that all or any part of a "resource” exists or is economically or legally mineable. Investors are also especially cautioned that the mere fact that such resources may be referred to in ounces of silver and/or gold, rather than in tons of mineralization and grades of silver and/or gold estimated per ton, is not an indication that such material will ever result in mined ore which is processed into commercial silver or gold.
