1. meteorological and hydrologic data interpretation and water balance preparation; 
   

2. water quality sample collection and data interpretation; 
   

3. ML/ARD data collection and interpretation as well as long-term predictions including geochemical modelling; 
   

4. sediment transport modelling and sedimentation control system design;
   

5. contributing to out fall diffuser design; 
   

6. groundwater and surface water quality prediction modeling; and, 
   

7. water treatment system specification development, amongst others.   
   

    This work secured a Mines Act Permit and a Discharge Approval under the Environmental Management Act, enabling construction of the mine to commence.
