The San Francisco Mine is located in the state of Sonora, Mexico, approximately 120 kilometres south of the United States-Mexico border.
San Francisco declared commercial production in April 2010, and since that time has produced over 820,000 ounces of gold.
Active mining ceased early in 2019 and the operation processed stockpiled material through the end of the calendar year.
In 2020, the San Francisco mine will enter residual leach and Alio Gold expects to recover between 12,500 and 15,000 ounces of gold.
At the conclusion of the residual leaching operation, Alio Gold will place the mine on care and maintenance while the Company explores value-enhancing alternatives for the operation.
