2326 Figure 3. Main and complementary works of the Mirador Mine Due to intense rainfall, steep topography, and soil characteristics, slope failures occur frequently in the area, particularly in zones disturbed during construction. Exposed areas are highly susceptible to erosion, which can increase suspended solids concentrations in nearby drainages. 2. ENVIRONMENTAL MANAGEMENT Environmental management is a priority axis in mine operations, with management plans implemented for water and soil control. Key measures include runoff control systems using channels that separately convey clean water and process water, preventing mixing and discharge without treatment into natural bodies. Crown, perimeter, and cross channels have also been constructed on slopes and waste dumps to reduce erosion. To date, 76.73 km of these systems have been built. To control sediment transport, sedimentation systems have been implemented, including the East ponds, North Pit pond, North Waste Dump ponds (systems AB and C), and system E for capturing runoff from the North Pit. In addition, daily monitoring of pH and total suspended solids (TSS) is conducted prior to discharge. Water, soil, and air monitoring points have been implemented with monthly and quarterly frequencies, along with the installation and operation of five meteorological stations operating in real time. 2.1 Environmental rehabilitation and revegetation One approach to landscape improvement, soil recovery and protection, and erosion control is the revegetation of degraded areas. Understanding the most suitable species for each site is essential; therefore, EcuaCorriente S.A. conducted a study with specialists to identify pioneer vegetation that enables recovery of disturbed areas.
