Southern Copper Corporation has officially secured authorization to commence exploitation activities at its Tía María copper mine project in Peru’s Arequipa region, marking a significant milestone in one of the country’s most controversial mining developments. With an updated investment budget of approximately $1.8 billion, the company plans to initiate full-scale construction in 2025 and begin commercial production by the second half of 2027.
Located in the province of Islay near the Valle de Tambo, the open-pit Tía María mine is designed to produce 120,000 tonnes of copper cathodes annually at peak output. The project aims to extend operations for roughly two decades and is expected to become a major economic driver for southern Peru, generating hundreds of direct jobs and thousands more indirectly, while contributing substantial export revenues and fiscal income through taxes and royalties.
After years of social unrest marked by protests and fatalities between 2011 and 2015, Southern Copper has worked to rebuild relations with local communities surrounding the project. Despite lingering concerns, particularly from agricultural stakeholders worried about potential impacts on water supplies and farming livelihoods, the company maintains that the mine will not draw freshwater from the valley. Instead, it will exclusively use desalinated seawater transported through dedicated infrastructure, a measure intended to mitigate environmental risks.
The advancement follows the approval of key environmental reviews, including the Third Technical Sustainability Report (ITS), which details crucial adjustments to the mine’s infrastructure. These include relocating and modifying mining workshops, industrial waste facilities, explosives storage, water tanks, and nitrate warehouses within specific project zones such as Tajo La Tapada and Pampa Cachendo. The report also highlights improved lining and impermeabilization of dynamic leaching piles in line with the latest mining safety and technology standards. Overall, these adjustments represent an additional investment of more than $4 million to optimize operational efficiency and environmental safeguarding.
The project’s construction phase is scheduled to span approximately 29 months, encompassing permitting, engineering, procurement, and main infrastructure works. Key facilities to be developed during this period include a desalination plant, a high-voltage power transmission line, a primary crusher, and a conveyor belt system connecting the mining pit to processing zones. Following construction, a six-month commissioning phase will precede the commencement of full-scale operations expected to last for 15 years at the Tajo La Tapada pit, with subsequent closure activities planned around year 21 of the project timeline.
From a workforce perspective, the project is anticipated to create around 3,500 jobs during construction, prioritizing local hiring, and maintain approximately 764 direct and nearly 4,800 indirect positions during operations. The infusion of capital and employment opportunities aims to bolster the economic fabric of Arequipa while positioning Peru to strengthen its global copper supply role amid rising demand fueled by clean energy technologies.
Southern Copper’s executive leadership has expressed confidence in meeting the established schedule, citing extensive experience with similar operations across their Peruvian and Mexican mines. Despite historical challenges, the company underscores ongoing commitment to responsible mining practices, dialogue with affected communities, and adherence to stringent environmental standards.
While the project moves forward without reported incidents in recent months, the social dynamics remain delicate, with local organizations emphasizing the necessity for transparent monitoring and enforceable guarantees. As Peru seeks balance between investment promotion and community rights protection, Tía María stands as a critical test case for sustainable mineral development in the region.
With copper prices projected near $4.25 per pound in the coming years and global demand for the metal intensifying—driven by the energy transition—the success of Tía María could significantly influence Peru’s economic trajectory and Southern Copper’s position within the international mining sector.
