Lucky Friday | Mullan, Idaho
Lucky Friday is a deep underground silver, lead, and zinc mine located in the Coeur d’Alene Mining District in northern Idaho. Hecla now controls 100% of the Gold Hunter deposit, also known as the Lucky Friday Expansion Area, after completing acquisition from Independence Lead Mines Company in the 4th quarter of 2008. Lucky Friday is one mile east of Mullan, Idaho, and is adjacent to U.S. Interstate 90.

Lucky Friday resumed limited production in February 2013, and full production in late September 2013.  In 2014, ore was processed at an average rate of 850 tons per day and produced 3.2 million ounces of silver.

The #4 Shaft Project is a key growth project that is currently excavated to the 7835 level. The #4 Shaft Project is 85% completed, and is expected to be finished in the fourth quarter of 2016, allowing access to higher-grade zones beginning in 2018 once the associated development is concluded. The #4 Shaft Project is expected to cost approximately $225 million, with about $41 million left to be spent over the next two years.

The plant has a full surface facility complete with a 1,000 tons of ore per day mill, which produces lead and zinc concentrates. These concentrates are currently shipped for treatment via truck to Teck Cominco Metals Ltd. smelter in Trail, BC, Canada. All production is by underground methods, which include both underhand and overhand mining. The coarse mill tailing is mixed with cement and used as backfill. Production is via ramps and transfers, and substantially utilizes jumbo drills, mechanized mining, and truck haulage to the Silver Shaft. Access to the underground workings is via the 18-foot diameter, concrete lined, Silver Shaft.
