The making of every metric tonne
Long-hole open stoping
Ore is extracted through precise drilling and blasting, enabling deeper access, controlled breakage, and safer operations.
Cemented paste fill
Mined out voids are backfilled with paste prepared from a mixture of mill tailings and cement, maintaining ground stability and enabling safe, continuous extraction sequences.
Underground ore handling
Ore is crushed underground and conveyed directly to the skip hoisting system, reducing surface handling requirements and improving overall material flow for hoisting.
Vertical ore transport
Crushed ore is hoisted to the surface using shaft‑based skip hoisting systems, providing fast, efficient vertical transport with minimized energy losses.
Milling and flotation
Surface plants process ore through grinding and flotation, yielding high-purity zinc and lead concentrate for further refining.
Ventilation, dewatering, automation
Advanced support systems enhance safety, water reuse, and process control, enabling round-the-clock, optimised operations.
