Environmental Approval Granted for Major Mining Project
Santiago, Chile – Chile's state-run mining company, Empresa Nacional de Minería (ENAMI), announced on Wednesday, October 29, 2025, that it has secured the environmental permit for its ambitious $1.7 billion copper smelter project. This crucial approval marks a significant step forward in the modernization of its Hernan Videla Lira smelting facility, located in the northern Atacama region. The permit was granted by Chile's environmental review agency, the Environmental Assessment Service (SEA).
Project Scope and Enhanced Capacity
The new facility, part of a comprehensive upgrade to the existing plant in Paipote, is designed to substantially increase Chile's copper processing capabilities. Upon completion, it will have the capacity to process up to 850,000 metric tons of copper concentrate annually. Additionally, its electrolytic refinery is projected to produce up to 240,000 tons of copper cathodes per year, which are essential materials for electronics, construction, and renewable energy vehicles. This modernization effort is expected to practically triple the capacity of the old smelter, positioning Chile to meet the accelerating global demand for responsibly produced copper.
Commitment to Sustainability and Modern Standards
A key aspect of the project is its strong emphasis on environmental performance and sustainability. The upgraded smelter is engineered to comply with Chile's strict new emission standards and international ESG (Environmental, Social, and Governance) benchmarks. It aims to cut sulfur dioxide emissions by more than 95%, improve energy efficiency, and integrate digital control systems for enhanced traceability and safety. Iván Mlynarz, ENAMI's Executive Vice President, highlighted the significance of this approval, stating that it 'represents a decisive step toward a cleaner and more competitive copper industry.'
Financing and Strategic Importance
The $1.7 billion investment required for the project has attracted considerable international interest. ENAMI has been actively exploring various financing structures and has seen interest from approximately 15 companies, including major miners, global traders, investment funds, and international banks. Mlynarz noted that the interest from global copper consumers in expanding their supply chains could be instrumental in securing the necessary funding. The modernization of the Hernan Videla Lira smelter is considered vital for enhancing domestic value addition in Chile's mining sector, reducing the country's reliance on exporting raw copper concentrates, and supporting its broader decarbonization and re-industrialization strategy. Construction is anticipated to commence once financing arrangements are finalized, with operations projected to begin later this decade.

This project promises a cleaner and more competitive copper industry, which sounds promising for future growth. However, the focus on "responsibly produced copper" needs to be backed by transparent, independent oversight to truly reassure the public about its environmental claims over time.

Increasing copper cathode production for green technologies is a strategic move for Chile's economy and global demand. Still, the article doesn't detail the water usage requirements or the impact on the already arid Atacama region, which is a common concern for mining operations there.

$1.7 billion is a huge risk. What about the real cost to local communities?

The commitment to ESG benchmarks and modernization is commendable for bringing the smelter up to modern standards. Yet, even with these improvements, the sheer scale of processing 850,000 tons of concentrate annually raises questions about overall resource consumption and waste management.

While the reduction in sulfur dioxide emissions is a positive step for air quality, we need to ensure local ecosystems aren't negatively impacted by other aspects of such a large-scale operation. The long-term monitoring will be crucial.
