Abstract: This paper describes the role of the corporate ground control function within Hecla Ltd., a mid-tier US precious metals producer. The position of the ground control function within the corporate structure and the primary responsibility of evaluating and communicating geotechnical risk at company operations and during acquisition is emphasised. A case example is given of how the corporate ground control function was involved in recent ground support issues encountered during the sinking of a 3,000 m deep shaft at the Lucky Friday mine.
