The success of mining operations depends on multiple factors during their establishment, being one of them the water access. Currently, a major issue facing mining projects is the utilization of water resources, making it crucial to ensure both the quality and quantity of water without causing harm to the local communities or their surroundings. The focus of this study was the “El Toro“ mining unit, which is operated by Summa Gold Corporation. It is situated in the mining area where gold deposits associated with the Chimu formation are found and is controlled by structures that run in a north-west direction. This deposit can be found in the Huamachuco district, located in the Sanchez Carrion province, within the La Libertad region. It is currently regarded as one of the top five gold producers in large-scale mining operations in the country. The presence of relatively small population areas, in addition to agricultural and livestock areas around the mining unit, make it necessary to make optimal use of water resources during mining operations until the economic mineral is obtained, being the months of drought the period in which the problems become more acute to the point of rationing and even stopping operations for intervals of time, damaging the daily activities. This research commenced with a desk research phase, during which relevant bibliographic information was analyzed and reviewed. The hypothesis was defined, as well as the relevant variables to develop the work. During the fieldwork, the initial performed task was to survey the study area where the geological and structural characteristics were noted, the drillings conducted at the core shack were also reviewed and identified the Farrat formation as the most significant feature due to its composition of thick sandstones with immense strength. Then, geophysical prospecting was carried out, which is a science widely used for groundwater exploration where the electrical tomography method was applied to identify favorable areas that may contain aquifers. In another study, the most important surface and subway water points were monitored, and a physicochemical evaluation of the water was made to determine its quality and potential use. This task consisted of regularly checking the water levels of the piezometers that were installed, computing the flow rates of the springs, and documenting the physicochemical properties in situ. Once all the information regarding the cabinets and fields had been collected and processed, the results were moved to further examination. The main goal of this analysis was to find a solution to the issue of water availability and achieve the objective of the study. Given the results of the work done, it was established that there are two points in which it is more feasible to extract the water resource, being these future wells in two different micro-watersheds, located on the opposite side of the Mining Unit. Likewise, according to the requirements of the operating areas, the quantity of water utilized for extraction will have a negligible effect on the primary aquifer and will only be used during a short period (dry season), as decided by the hydrogeology expert.
