La Coipa Mine is located in the Atacama region of northern Chile, approximately 1,000 kilometers (km) north of Santiago and 140 km to the northeast of Copiapó, Chile.
Knight Piésold assumed the Engineer of Record (EoR) responsibilities in 2014 for the Rahco and Rakito filtered tailings storage facilities (FTSF). The tailings storage facilities at La Coipa were constructed as a filtered stack operation, where filtered tailings are placed by conveyor and then nominally compacted.
As part of our work we have been involved in the following studies:
The work being done at La Coipa will result in a more efficient closure plan for the Rahco and Rakito stacks as Phase 1 and the evaluation of tailings storage alternatives for future Project expansion as part of Phase 2.
