Argentina Approves Los Azules Copper Mining Project Under RIGI Framework

Los Azules Copper Project: Argentina's Landmark Mining Approval

The Los Azules copper project stands as one of Argentina's most significant mining developments, strategically positioned in San Juan Province within the Andes Mountains at an elevation of approximately 3,500 meters. This ambitious project, with Canadian mining company McEwen holding a 46.4% ownership stake, recently secured crucial governmental approvals that position it to become the first operation in Argentina dedicated to producing high-purity copper cathodes for industrial applications.

The project represents a substantial investment in Argentina's mining sector, with total capital requirements estimated at $2.7 billion. Under the leadership of Michael Meding, who serves as VP of McEwen Copper and General Manager of the Los Azules project, the development is advancing through critical pre-construction phases.

"This approval reinforces McEwen Copper's long-term commitment to Argentina and the Province of San Juan, advancing a model of modern, responsible and sustainable mining," Meding noted following the government authorization, according to Engineering & Mining Journal (October 2025).

How Did Los Azules Secure Government Approval?

RIGI Approval Process

The Los Azules copper mining project approval was achieved under Argentina's innovative Regime of Incentives to Large Investments (RIGI), a program introduced under President Milei's administration. This approval, officially announced by Argentina's Minister of Economy, Luis Caputo, marks Los Azules as the eighth project to qualify under the RIGI framework.

The RIGI program creates operational predictability and establishes clear parameters for engagement between mining companies, the Argentine government, and potential investment partners. For Los Azules, this integration "enhances operational predictability and establishes a clear framework for engagement with the State and future partners," according to project management statements published in Engineering & Mining Journal (October 2025).

Environmental Impact Assessment Success

Prior to the RIGI approval, the Los Azules project achieved another critical regulatory milestone in December 2024 when it secured its Environmental Impact Declaration for both construction and operation phases. This comprehensive assessment represented the culmination of:

• Extensive environmental documentation review
• Public consultation processes with local communities
• Multi-agency technical evaluations
• Assessment of proposed environmental mitigation strategies
• Detailed water management plans

The successful environmental approval underscores McEwen Copper's commitment to responsible resource development and sustainable mining practices in the high-altitude Andean region.

Project Readiness Status

With both RIGI and environmental approvals now secured, the Los Azules project has positioned itself for the construction phase, pending several final prerequisites:

• Completion of detailed engineering designs
• Securing the $2.7 billion project financing package
• Finalization of the feasibility study (expected by end of October 2025)

The progress demonstrates Argentina's commitment to developing its mineral resources while maintaining environmental standards and creating a framework for foreign investment in the mining sector.

What Makes Los Azules a Significant Copper Resource?

Resource Estimation and Grade Quality

Los Azules represents one of the world's largest undeveloped copper investment strategies with substantial verified resources. According to technical assessments reported by Engineering & Mining Journal (October 2025), the project contains:

These resource estimates position Los Azules among the top-tier copper projects globally, with a significant metal endowment that supports decades of production.

Production Capacity and Lifespan

The project's operational parameters demonstrate its substantial scale and long-term economic potential:

• Annual Production: 322 million pounds of copper cathode (average)
• Mine Lifespan: 27 years of active operations
• Production Type: High-purity copper cathode
• Market Distinction: First operation in Argentina designed to produce high-purity copper cathodes

This production profile makes Los Azules a significant contributor to global copper supply at a time when demand for the metal is increasing due to its essential role in renewable energy technologies, electric vehicles, and modern infrastructure.

How Will Los Azules Implement Sustainable Mining Practices?

Renewable Energy Commitment

The Los Azules project has established ambitious sustainability targets that place it at the forefront of responsible mining development in Argentina. Central to these commitments is the pledge to operate using:

• 100% renewable energy sources for operations
• Energy-efficient processing methods to minimize consumption
• Modern power management systems to optimize usage patterns

This renewable energy commitment not only reduces the project's environmental footprint but also insulates operations from potential fuel supply disruptions and price volatility associated with conventional power sources.

Carbon Neutrality Roadmap

McEwen Copper has articulated a clear environmental strategy for Los Azules that includes a defined path to carbon neutrality:

• Carbon Neutrality Target: 2038
• Emissions Reduction Plan: Phased approach with interim measurement targets
• Monitoring Systems: Advanced emissions tracking technology for real-time data

This comprehensive approach to emissions management demonstrates the project's alignment with global climate initiatives while establishing a benchmark for other mining operations in Argentina and across South America.

Water Conservation Approach

Operating in an arid, high-altitude environment necessitates careful water management. The Los Azules project incorporates several water-efficient design elements:

• Closed-loop water recycling systems to minimize fresh water requirements
• Minimal freshwater consumption through process optimization
• Advanced water treatment facilities to ensure environmental protection
• Monitoring systems to track usage and maintain regulatory compliance

These water conservation measures address one of the most significant environmental challenges facing mining operations in mountainous regions.
