CIM Vancouver Branch September Luncheon
Title: Deep Mining Challenges at the Lucky Friday Mine
Company: Hecla Mining
Speaker: Wes Johnson, Senior Mine Engineer
Hecla Mining operates the Lucky Friday silver-lead-zinc underground mine located in the Coeur d’Alene Mining District in northern Idaho. The Lucky Friday Mine recommenced production in 2013, and ramped up to full production by September 2013. All production is by underground mining methods; at depths of approximately 6,000 feet (1.8 kilometers). Hecla Mining is in the process of sinking the new #4 Shaft, to an ultimate level of 8,800 feet (2.7 kilometers), and reviewing optimal mining and processing rates. Hecla Mining will present some of the challenges encountered in developing and operating the deep underground Lucky Friday Mine.
