Mine water balance modeling:

• Goldsim water balance models were developed for scenario analysis and water management decision making purposes on both operational and management levels.
• Projects throughout Africa and South Africa on gold, diamond, iron ore, copper, coal, nickel, base metal mines.

Tailings dam water balance modeling:

• Goldsim models to simulate the water balance around a tailings dam. Modeling usually includes return water dam sizing.
• Rainfall inputs are generally stochastic to allow for scenario analysis, long-term analysis or the statistical analysis for short-duration projects.
• Mining projects throughout Africa and South Africa on gold, diamond, copper, coal, nickel, base metal, and iron ore tailings dams.
• Industrial projects on power stations, iron and steel works.

Open cast pit water balance modeling:

• Goldsim models to calculate pit water make in opencast operations, especially pits that have concurrent excavation and rehabilitation. Modeling takes into account the dynamics of the working pit configuration and rehabilitation progress during the simulation period.
• Rainfall inputs are generally stochastic to allow for scenario analysis, long-term analysis or the statistical analysis for short-duration projects.
• Modeling typically involves final void sizing for closure planning.
• Projects throughout Africa and South Africa on gold, copper, diamond, iron, ore, coal (with concurrent rehabilitation).

Water quality modeling:

• The water quality modeling related to pollution control dams involves modeling conservative variables, taking into account the surrounding catchments, dam operating rules and hydrology associated with the system. Daily continuous modeling is used in conjunction with relevant regulations (e.g. Regulation 704 of the South African National Water Act) to formulate solutions for clients.
• Water resource projects involve determining the likely impact of process and contaminated stormwater discharges from mines and industry.
• Mining projects throughout Africa and South Africa on gold, copper, nickel, coal mines (discard dumps and in pit water quality).
• Industrial projects throughout South Africa on power stations, chrome and steel plants, aluminium smelters, oil producers.
• Water resource projects in the DRC and throughout South Africa. Major rivers include the Olifants and Tugela Rivers in South Africa.

Mine water balance modelling for ICMI Cyanide code compliance:

• Developed probabilistic mine-wide water balance models for scenario analysis and water management decision making purposes - a requirement of the ICMI Cyanide code. The models have been extensively audited and accepted as suitable water balance models for ICMI Cyanide code compliance.
• Project locations include South Africa, Namibia, Ghana, Mali, and Guinea.

Sediment surveying and modeling:

• Involved in the sediment surveys that were conducted on the Katse and Muela dams that form part of the Lesotho Highlands Water Project. Experience includes mapping floor profiles using sonar equipment and calculatingsediment volumes.
