the 20 mg/L CNTOT standard. The highest

Birds continue to nest and breed near the tail-
ings storage facility, confirming that our cyanide 
discharge presents no environmental hazard. 
Ongoing cyanide destruction is also assisted by 
numerous introduced micro-organisms which 
are able to degrade free cyanide to carbon 
dioxide and ammonia.
Dust Management
Chatree’s aim is to produce minimal dust and 
noise and thereby reduce neighbouring concerns 
by maintaining all mine roadways in good order 
through regular gravel sheeting and watering. 
Effective noise bunds have been developed 
around operations. In some circumstances, 
operations have been restricted to daylight 
hours. Dust monitoring stations have been 
established in nine surrounding villages. All 
results from the regular monitoring and 
sampling program have been within required 
quality standards.
Incident Reporting
There were 66 environmental events during the
