Buenos Aires and Santiago – Presidents Javier Milei of Argentina and José Antonio Kast of Chile are spearheading a renewed effort to modernize the Mining Integration and Complementation Treaty, a 1997 agreement that was revived in July after years of stagnation. The goal is to create a legal framework that lets mining companies share infrastructure across the Andes, opening the door to billions of dollars in private investment.
Government push aligns with private‑sector goals
Chile’s Mining Minister Daniel Mas told reporters this month that the treaty could unlock more than $20.7 billion in new projects and add roughly 540,000 metric tons to annual copper output. The administration sees the Andes corridor as a strategic conduit for Argentine mines to access Chilean ports and the world‑class logistics network that supports the planet’s largest copper producer.
Both leaders framed the initiative as a win for families and the Constitution‑based free‑market principles they champion. By reducing transport costs and shortening supply chains, the treaty is expected to lower the price of copper – a metal essential to the energy transition – and create well‑paying jobs in both nations.
Key projects poised to benefit
Three major developments are slated to discuss the treaty at a mining‑integration seminar in Santiago on Friday. McEwen Copper’s Los Azules project in Argentina, Glencore’s El Pachón, and the cross‑border Vicuña venture – a partnership between Lundin Mining and BHP – are all positioned near the border and could tap Chilean infrastructure.
Los Azules has not committed to using desalinated Pacific water or exporting through Chilean ports, but its proximity to the border makes the talks relevant. Vicuña plans to draw desalinated water from the Pacific, though it has not confirmed whether Chilean facilities will be used. BHP declined to comment on its infrastructure plans.
Economic impact and regional significance
Argentina, traditionally an agricultural exporter, has not produced copper since the Alumbrera mine closed in 2018. Analysts say a pipeline of new projects could lift the country into the world’s top ten copper producers by 2030, positioning it alongside Chile as a critical supply hub for the metal that powers renewable energy, electric vehicles and modern industry.
Chile’s Deputy Mining Minister Álvaro González cautioned that there is no fixed timeline for implementing the treaty’s measures, but emphasized that the technical review of eligible projects will move forward in the coming weeks.
What this means for investors and local communities
For investors, the treaty offers a clearer regulatory path and the promise of shared infrastructure, which can reduce capital expenditures and accelerate project timelines. For local communities, the influx of private investment could translate into new jobs, higher tax revenues and improved infrastructure, all while respecting the constitutional right to private enterprise.
Both administrations have highlighted the partnership as a model of regional cooperation that respects market freedom and supports family‑centered economic growth.
