David has extensive experience in facility earthworks layout, mine water management mine closure, including design of surface water conveyance, stormwater structures, and water storage structures for surface water and solution flows. He has also been developing probabilistic, dynamic water balances for mine sites for most of his career, using a variety of tools such as Excel, OpSim, and GoldSim to simulate the management of process solutions, AMD, runoff, and groundwater flows for a wide variety of mining projects, from coal to precious metals and from prefeasibility to operational and closure facilities. David is an industry recognized expert in GoldSim water balance modeling. He first became involved in GoldSim simulation software during the early development of the tool in the late 90’s and has been an intensive user of it ever since.
