At Certej, the project is designed to use filtered tailings, where processed material is filtered and stored in a stable, dry form. This is widely recognized as a best available technology for tailings and mine waste management.
In traditional mining operations, ore is crushed and processed to separate minerals from the surrounding rock. The waste material from this process is called “wet tailings”. Traditional wet tailings are a liquid mixture of water and non-mineral rock. Storing wet tailings material requires the construction of dams and is a common practice globally.
VarDev’s strategy is to invest in filtration technology that separates water from crushed rock, producing a stable, filtered material. This material is then combined with waste rock from the mine and stored in areas designed for safety and stability.
Filtered mine waste management is a proven technology that has been safely applied at mining operations in Europe and globally.
