The Augusta Resources Corporation proposes to construct the Rosemont Mine project in the northern Santa Rita Mountains. This report is a reconnaissance analysis of the conceptual flow and water balance in the area. The conceptual flow model for the area is based on topography, geology and precipitation and identifies the likely flow paths in the watershed and aquifer system. The water balance includes estimates of recharge to and groundwater flow from the area; there is no evapotranspiration discharge from the regional groundwater.
