In 1985, exploration drilling discovered gold mineralization approximately two kilometres south of the Kremzar Mine. Periodic exploration work continued over the years and in 2004, an exploration program was undertaken to complete a Mineral Resource estimate. Island Gold achieved commercial production in October 2007 and has since produced over 700,000 ounces of gold. In November 2017, Alamos Gold acquired Richmont Mines and the Island Gold mine.
