(1) The term “reserve” means that part of a mineral deposit that can be economically and legally extracted or produced at the time of the reserve determination. Low lake levels and increased demand in the Juneau area combined to restrict the amount of power available to Greens Creek prior to 2009.

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.At Greens Creek, the 846,076 tons processed at the mill in 2019 contained 12.4 million ounces of silver, 81,223 ounces of gold, 62,863 tons of zinc, and 24,704 tons of lead. All rights reserved. During 2012, the mine again received an increased proportion of its power needs from AEL&P. This website 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. In 2009 and 2010, the mine received an increased proportion of its power needs from AEL&P. Measured and indicated gold resources measure 835,000 ounces and inferred gold resources measured 159,000 ounces.Drilling efforts have replaced production and added new reserves. The term “resource” does not equate to the term “reserve”. Hydroelectric power was also available during 2011, but to a lesser extent compared to the previous two years due to lower precipitation.

Lucky Friday mine in Mullan, Idaho To apply for current job openings at Lucky Friday, please complete a Hecla Lucky Friday Application for Employment and submit it as detailed below. Production in 2020 is expected to be 8.9 – 9.3 million silver ounces at a cash cost, after by-product credits, of $4.25 – $5.00 an ounce (1).Hecla’s various subsidiaries own 100% of the Greens Creek mine located in Southeast Alaska.

These deformational episodes have imposed multiple folding of the orebodies to create a complex geometry. The massive ores are further subdivided as either being base-metal or pyrite dominant.

In the 200 South Zone, drilling intersections at the northern end of the 200 South Bench over 200 feet of strike length include 16.8 oz/ton silver, 0.24 oz/ton gold, 12.7% zinc and 6.1% lead over 22.4 feet. Installation of the necessary infrastructure was completed in 2006, and use of hydroelectric power commenced during the third quarter of 2006. In the past three years, most of the power has come from AEL&P.There are three main phases to the mining process: development, production, and backfilling.The mine holds current proven and probable silver reserves of 130.9 million ounces, 932,000 ounces of proven and probable gold reserves, as well as 305,190 tons of lead and 778,410 tons of zinc in proven and probable reserves.There are an additional 101.1 million ounces of silver measured and indicated resource and 25.4 million ounces of silver inferred resources. White ores are subdivided into three groups by the dominant gangue mineralogy; white carbonate, white siliceous, and white baritic ore. Greens Creek is a large, underground silver mine located in Southeast Alaska, which also produces smaller amounts of gold, lead, and zinc.
