Mines Performance
ZAWAR GROUP OF MINES
Zawar Mines (ZM) continues to advance through innovation, achieving continuous expansion and sustained productivity while ensuring responsible and sustainable operations. Operating since the pre-digitalisation era, this group of four mines – Mochia, Balaria, Zawarmala and Baroi – has consistently set new benchmarks in innovation and operational excellence to optimise processes and boost efficiencies.
KEY OPERATIONAL MILESTONES, FY2025
FY2025 was a milestone year for ZM, with the highest-ever metal in concentrate (MIC) of 210 kt, up 18% YoY. It commenced mining from crown stopes at Mochia Mine, secondary stopes in Central Mochia Mine and doubled the ore production from Zawarmala Mine in the last two years by improving paste filling and innovative stoping. These developments are expected to significantly enhance its production levels.

OPERATIONAL AND STRATEGIC DEVELOPMENTS
- Mined a geologically highly complex ore body AK-BK4 lens at 190 mRL with 500 kt ore production at Baroi Mine
- CW0 crown stopes at 57 mRL to 27 mRL with 98% stope recovery by innovative and safe design at Mochia Mine
- Achieved highest-ever pull per blast of 3.61 m, and best-ever mill recoveries of 93% for zinc, 92% for lead, and 81% for silver through specific silver promoter optimisation and installation of advanced process control and flow meters in flotation circuits
- Implemented digital monitoring of equipment to enhance utilisation and identify and minimise idle time in ZM
- Established an 18.5 km leaky feeder network at ZM to improve the underground communication system
- Replaced 50+ years old underground crusher with a new generation advanced Sandvik crusher at Balaria Mine to improve capacity of production incline
- Established connection drive between Central Balaria and Western Balaria at -180 mRL to debottleneck hauling from Central Balaria by 65 MT trucks
SAFETY AND ENVIRONMENTAL DEVELOPMENTS
- Completed the Company’s 2nd longest and ZM’s longest raise boring of 576 m from surface to -205mRL at Balaria Mine, improving the ventilation in lower block
- Upgraded winder for Mochia, Balaria and Zawarmala shafts to improve safety, reliability and productivity
- Installed a skip interlock switch with NO-GO line at 430 mRL at Zawarmala for enhanced safety
- Fully enclosed chute and replaced skit plate at Mill 1 to reduce dust emission and spillage
- Commissioned rammer to reduce secondary blasting
- Developed safe and designated area for HEMM parking at the Mochia-Balaria portal
- Installed cameras on both sides of the Development Drill Jumbo (M2D) for blind spot area elimination
