From 2008 to 2012, the project included a technical audit of available hydrogeological data, and developing and implementing a field hydrogeological program in Colombia. The goal was to use 3D groundwater modelling to assess possible groundwater inflow rates, pore pressure distribution for pit slope analysis, and the potential impact to the groundwater and surface-water systems along a 7km-long highwall adjacent to a major river. SRK worked with CMSA to optimise the mine design and production schedule, including the estimate of mining capital and operating costs. These estimates were used in selecting the preferred mine equipment fleet and mining schedule for long-term mine development.
