Minera Florida is an underground gold and silver mine located 75 km southwest of Santiago in central Chile. The underground workings are developed by adits with an internal ramp system that provides access to production stopes. The mine uses 25-tonne mechanized articulated haul trucks to transport ore from the mine to a transfer point where 50-tonne trucks then haul the ore to the process plant.
The Alhué process plant is currently operating at a rate of 2,200 tpd where ore is crushed in three stages in a closed circuit through two ball mills and a cyclone cluster. The cyclone overflow is then delivered to the flotation circuit where gold and silver are recovered. The average recovery rate during 2017 has been 88% for gold and 62% for silver and the resulting production totaled 47,000 ounces of gold and 470,000 ounces of silver.
Yamana is directing development and exploration efforts towards a strategic target of 130,000 ounces of gold production per year.
