La mina Bolivar es una operación de minería subterránea de 3,000 toneladas por día, localizada en Chihuahua, México, la cual produce cobre, zinc, plata y oro. Las limitaciones de espacio en el terreno montañoso requieren el desaguado de relaves para reducir las áreas requeridas para el almacenamiento de relaves. Tierra Group está ayudando a Sierra Metals con el proceso de actualización incluyendo el desaguado de relaves y almacenamiento. Tierra Group está completando un estudio conceptual para determinar la solución de desaguado más económica que se ajuste con el funcionamiento de la actual planta y planes futuros. Los diseños de ingeniería incluyen pruebas especializadas de relaves, desarrollo de diagramas de flujo de relaves, especificación de equipos, estimación de costos, y la estimación del cronograma de construcción y entrega.
