Features Projects

	Candelaria Mine, Atacama, Chile Hydrogeological Studies of Existing Tailings Impoundment and Open Pit Conceptualization, construction, calibration and flow calculations of a steady and transient numerical modeling using FEFLOW in order to evaluate potential effects that the proposed mine expansion may have on the groundwater system in the surrounding area.
	Gold Fields, Cerro Corona Mine, Peru Hydrogeological Studies of Tailings Impoundment and Open Pit expansion Numerical model construction, calibration, simulation and sensitivity analysis for Environmental Impact Assessment of mine development. The modeling included FEFLOW ground water modeling in transient conditions, including pit expansion, tailings facility and mine waste facility development.
	Pueblo Viejo Mine, Dominican Republic Hydrogeological Studies of a future Tailings Impoundment Groundwater and surface water modeling. The modeling included FEFLOW ground water modeling and his interaction with a MIKE SHE Model in transient conditions, including tailings facility development. Transport and reactive transport of TSF seepage modeling.
	Zafranal Project, Peru Feasibility Level Hydrogeological Studies for New Mining Project Groundwater and surface water modeling related to EIA and feasibility level engineering studies including: evaluation of surface water and groundwater supply options; hydrogeological characterization of tailings facility and mine waste areas;  evaluation of mine dewatering and depressurization requirements.
	Antamina Mine, Peru Hydrogeological Model for Open Pit Depressurization and Regional effect Construction of a 3D numerical model in FEFLOW, calibration, sensitivity analysis and prediction simulations of future pit design. The numerical model was created and run with the purpose of assessing pit pore pressures in future pit stages to be used in the geotechnical analysis of pit design and stability and also understand the regional effect of the pit dewatering.
	Salar de Maricunga Lithium Project, Chile Hydrogeology Studies and Brine Resource Evaluation Management and execution of numerical flow, density and transport model to define lithium and potash resources. The model is a comprehensive tool to support the environmental permitting process. It combines a fully-coupled FEFLOW and MIKE SHE to simulate groundwater and surface water interactions.
