Horning became president and general manager upon Sekulic's death in 1956. Between 1954 and 1958, the mine produced ores averaging 17.2 ounces of silver and 8.6 ounces of lead per ton. In Dec. 1958, Hecla Mining bought the shares owned by Featherstone and Horning, and continued to buy outstanding shares until Hecla became the major owner of Lucky Friday at 38%. In 1964 the Lucky Friday Silver-Lead Mines Company merged into Hecla Mining.
