Hannukainen Mine, Finland

Surface Water Hydrology Impact Assessment Water Balance and water quality modelling to support client decisions related to mine site development. The work included derivation of key hydrological parameters from baseline flow data, modelling impact of development on stream flows, working with hydrogeologists and engineers to better define mine impacts and preparing Hydrological Impact Assessment report.

EKATI Diamond Mine, Canada, Pit Late and Closure Studies

Modelling of water quality within open pits at the end of operations of EKATI Diamond Mine, as a key input into the mine closure planning process.

The modelling work also considered the likelihood of meromixis within the pit lakes and predicted water quality spilling from full pits to receiving environment. Work was completed in tandem with University of British Columbia, Canada.
