The study aimed to develop models that simulated hydrological conditions and sediment transport, facilitating the identification of potential impacts and the optimization of environmental controls. Additionally, Phase 1 of a hydrometeorological monitoring plan was implemented, which included the selection of appropriate instruments for measurement and their potential locations. It was anticipated that additional phases of the monitoring plan would be advanced to ensure continuous data collection and effective model updates.

Water balance model update for the mine’s operational components, phased towards the end of the life of mine (LOM), using GoldSim V.14 software. This activity included climate data updates, model calibration and optimization, as well as a detailed analysis of results and the development of strategic recommendations for efficient water resource management.

Hydrogeological investigation of the existing tailings facility and surrounding valleys.  The investigation includes: hydrogeologic mapping, structural mapping of fractures and fault zones, drilling and installation of multi-level monitoring wells, in-situ hydraulic testing, hydrochemistry,  data analysis, conceptual and numerical modeling.

Hydrogeological studies 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.  The ongoing studies include: hydrogeological mapping, drilling and installation of piezometers and pumping wells, hydrochemistry, hydraulic testing of aquifers, conceptual and numerical modeling and impact evaluations.
