Gold was originally discovered at Young-Davidson in 1916 and underground production began in 1934. Over the next 23 years, one million ounces of gold were produced from the Young-Davidson and nearby MCM Mine properties. The mine lay dormant between 1957 and 2005, when Northgate Minerals merged with Young-Davidson Mines Limited and began a surface exploration program and ultimately started construction of the operation. In 2011, AuRico Gold acquired Northgate Minerals and commenced open pit mining operations at Young-Davidson. First gold was poured in April 2012 and by October 31, 2013, the underground mine achieved commercial production. AuRico Gold merged with Alamos Gold in 2015.
