Mina Justa is an open pit copper project located in the Department of Ica aiming at the extraction of oxide and sulfide ores for copper production.

Last 7 September 2018, GyM, Graña y Montero building company, and Marcobre, a subsidiary of Grupo Breca, agreed on the beginning of the construction works of the mining project’s oxide plant that will consist of the corresponding civil works, 15 concrete vats and electromechanical assembly, within a period of approximately 21 months.

Thus, Graña y Montero will participate with their experience in Peru’s second largest mining execution project, thereby showing our clients’ trust in the quality of the services and added value we can offer to their projects and, in turn, strengthening the company’s portfolio of projects to execute in engineering, procurement and construction activities.
