Mining is carried out using traditional open pit techniques. Gold from the ore is recovered using dump and heap leaching techniques. According to the mining plan, the western section of the deposit, which hosts high-grade ore, is being mined first. The lower-grade ore, hosted in the eastern portion of the pit, will be mined at a later date.
