​ Tia Maria will generate significant revenues for the Arequipa region from day one of its operations. At current copper prices, we expect to export $18.2 billion and contribute $3.8 billion in taxes and royalties during the first 20 years of operation.

To the fullest extent possible, we intend to fill the 3,500 jobs estimated to be required during Tia Maria ´ s construction phase with workers from the Islay province. In 2027, when we start operations, the project will generate 764 direct jobs and 5,900 indirect jobs. ​ In the early construction phase, progress on access roads and platforms stands at 90%. We will advance these efforts alongside work to set up a temporary camp; engage in massive earthworks; and roll out mine-opening activities. To date, we have installed 59 kilometers of live fence to delimit the property. ​ Los Chancas - Apurimac: This greenfield project, located in Apurimac, Peru, is a copper and molybdenum porphyry deposit.
