Run-of-mine (ROM) ore is delivered to the heap leach pile from the mine by haul trucks. Lime is added to the ore prior to addition of the ore to the pad. Ore is placed in 10 m lifts and leached with cyanide solution. Pregnant leach solution is clarified filtered and de-aerated then treated with zinc dust to precipitate the precious metals.
