Chile · Mining
- New plan unveiled: Mining Minister Daniel Mas presented Chile’s new mining strategy on 13 August 2026 at Clapes UC in Santiago.
- “Less taxes”: the government proposes cutting the corporate tax rate from 27% to 23% and offering 25-year tax-stability contracts for strategic projects.
- Copper target: lift output back above 6 million tonnes a year, up from 5.415 million tonnes in 2025.
- Cross-border pipeline: reactivating the Chile–Argentina mining treaty is tied to about US$20.7 billion in projected investment and 540,000 extra tonnes of copper a year.
- Flagship project: the binational Vicuña district (BHP and Lundin) carries roughly US$18 billion in total investment and US$7 billion in first-phase capex.
- Faster permits: the plan aims to cut project approval times by 30% to 70%.
Santiago wants to win back mining capital with lower taxes and faster permits — and it is betting on a reactivated treaty with Argentina to unlock billions along the shared Andes.
Chile’s new mining strategy has a simple headline message: less tax, fewer delays, and a bigger door for foreign investors. Mining Minister Daniel Mas laid it out on Thursday, 13 August 2026, and paired it with a cross-border push to develop copper and lithium alongside Argentina.
What the “less taxes” pitch actually means
The core of the plan is a gradual cut to the corporate tax rate, from 27% down to 23%. The government also wants to offer tax-stability contracts that lock in the rules for up to 25 years, so investors know what they will pay decades from now.
Mas framed the goal in blunt terms. “Chile is not a mining country. Chile is a genuine mining power,” he said, arguing the country has been letting rivals catch up. The strategy also aims to speed up permits, targeting cuts of 30% to 70% in how long approvals take.
Why the Chile mining strategy is happening now
The numbers explain the urgency. Chile produced 5.415 million tonnes of copper in 2025, down from 5.831 million tonnes in 2018 — a drop of more than half a million tonnes while global demand for the metal keeps climbing.
There are signs the money is already circling. Since March 2026, sixteen mining projects worth about US$24 billion have entered environmental review, making up 83% of all investment currently in the national assessment system. The government now wants to turn that interest into shovels in the ground and push output back above 6 million tonnes a year.
The Argentina treaty and the US$20.7 billion figure
The second half of the plan looks east. Chile and Argentina have reactivated their Mining Integration and Complementation Treaty, first signed in 1997, with a binational commission meeting in Buenos Aires in July 2026.
Officials link the revived treaty to roughly US$20.7 billion in projected investment across the shared cordillera, plus about 540,000 additional tonnes of copper a year. The idea is to treat the border as one mining district rather than two, sharing infrastructure, logistics, and export routes.
The projects and the ports
The flagship is Vicuña, a joint venture between BHP and Lundin Mining that straddles the frontier. Its Filo del Sol deposit spans San Juan province in Argentina and Chile’s Atacama region, while the nearby Josemaría deposit sits on the Argentine side. A recent study put total investment near US$18 billion, with a first phase of about US$7 billion and copper output around 395,000 tonnes a year. A build decision is expected around the end of 2026.
Geography is the other selling point. Chile is offering its Pacific ports — Antofagasta, Mejillones, and Iquique — as export gateways for Argentine minerals bound for Asia. Routing through Chile can be roughly 40% shorter than Atlantic alternatives, which analysts say could cut Argentine transport costs by 15% to 25%.
Why this matters if you live in or invest in Latin America
Mining is not a niche story here. Copper is Chile’s single biggest export, and swings in investment ripple straight into the peso, government revenue, and jobs across the north of the country. A lower tax rate and faster permits could mean more construction, more hiring, and more foreign money entering the economy over the next few years.
If you hold Chilean or Argentine assets, or you are watching the region for opportunities, this is a signal that both governments are actively competing for the same global mining capital. The catch is timing: tax bills still need to pass Congress, and big projects like Vicuña will not produce copper until around 2030. The direction is clear, but the payoff is years out.
Frequently Asked Questions
What is Chile’s new mining strategy?
It is a government plan presented on 13 August 2026 to attract mining investment through lower corporate taxes, long-term tax stability, faster permits, and closer cooperation with Argentina. The stated goal is to lift copper output back above 6 million tonnes a year.
How much would the corporate tax fall?
The proposal is a gradual reduction from 27% to 23%, alongside tax-stability contracts of up to 25 years for strategic projects. The changes still need to pass through Congress before taking effect.
What is the Chile–Argentina mining treaty?
It is the Mining Integration and Complementation Treaty, originally signed in 1997 and reactivated in 2026. Officials tie it to about US$20.7 billion in projected investment and roughly 540,000 additional tonnes of copper a year along the shared border.
Which projects does it cover?
The headline project is Vicuña, a BHP–Lundin venture including the Filo del Sol and Josemaría copper-gold deposits on both sides of the frontier, with total investment near US$18 billion. Lithium and other copper prospects across the cordillera are also in scope.
