The President of the San Juan Mining Chamber (CMSJ), Iván Grgic, highlighted the close of an unprecedented 2025 in its history, with a succession of milestones achieved as decisive steps for the near future.

Minas Argentinas projects 30 years of development and employment for the mine located in the Jáchal department, in the north of San Juan province.

Juan Pablo Perea, San Juan’s Minister of Mining, presented the 2025 management report, highlighting advances in transparency, investment, environmental control, territorial development, and education, with record figures for the province’s mining sector.

The National Executive Branch included the amendment of the Glaciers Law in the extraordinary sessions, where environmental, mining, and federalism-related issues will be debated.

Glencore Pachón has launched activities for the 2025–26 summer season, during which more than 25,000 meters of drilling are expected to be completed in the Pachón and Carnicería valleys.

The initiative, located in the south of the province, proposes to produce copper oxide for agricultural fungicides, using controlled processes, with low environmental impact and an operational scheme typical of small-scale mining.

Cancambria is a project located in southern Malargüe that is beginning its prospecting phase through desk-based studies, with potential drilling exploration subject to results. The public hearing is scheduled for December 20.

With the activation of the UGA for PSJ Cobre Mendocino, the province adds its second environmental management unit—and the first for an exploitation project—in a key step toward unlocking mining activity after two decades of stagnation.

This initiative is moving forward in coordination with the National University of Catamarca (UNCA), within the framework of the transfer process and the new restructuring of Yacimientos Mineros de Agua de Dionisio (YMAD), a step that will grant the province majority control over the management of the state-owned mining company, together with the National University of Tucumán (UNT).

With projects beginning to move forward, the sector’s main constraint is no longer regulatory or geological, but rather the logistical capacity needed to sustain exploration.

While other jurisdictions negotiate with the federal government, Mendoza supports the bill that strengthens the provincial role in identifying protected areas and seeks to provide predictability for mining investment.

It signed an agreement with Distrocuyo to begin studies that will allow the construction of a new 220 kV transmission line and a transformer station in the high mountains of Mendoza. In this way, they aim to organize the project’s engineering and reduce uncertainty in an operation with high energy demand.

In modern mining, competitive advantage is no longer won solely at the deposit or in the process plant. It is increasingly defined in the supply chain: the system that ensures operational continuity, enables innovation, and sustains the social license to operate.

How artificial intelligence moves beyond promise and delivers tangible value across the mining supply chain through real, scalable applications.

The company activates the country’s first copper PEELP, a long-term strategic investment scheme under the RIGI framework, essential for financing the development of the Josemaría and Filo del Sol deposits.

The company is focusing the start of feasibility on achieving engineering accuracy for investment adjustments and the final CAPEX calculation.

The approval of the Environmental Impact Statement (EIS) for PSJ Cobre Mendocino not only unlocks investment in a province with a stagnant economic structure—it also underscores the resolve of Governor Alfredo Cornejo’s leadership.

With an investment of US$559 million, the project moves toward feasibility and aims to become both the first case of metalliferous mining development in Mendoza and the project that puts Argentina back on the world copper map.
