Argentina is racing to join the world’s top 10 copper producers by 2035, emerging from an eight-year hiatus in large-scale output after the 2018 Alumbrera mine closure. President Javier Milei’s pro-investment reforms have unlocked billions in capital, turning the country into a key geopolitical flashpoint for global critical minerals competition.
Home to 44 million tonnes of proven copper reserves and a core member of the Lithium Triangle holding over 70% of global lithium resources, Argentina is capitalizing on soaring energy transition demand for the metal. Of its $62.7 billion total planned mining investment, copper accounts for $42 billion — more than double the $18 billion earmarked for lithium. Mining Minister Luis Lucero has set a 10-year target of $20.6 billion in annual copper exports, a shift set to upend the country’s current gold and silver-dominated export mix.
Suggested Opportunity
The investment surge is driven by Milei’s sweeping reforms, which reverse years of policy instability, capital controls and regulatory unpredictability that once made Argentina a pariah for foreign investors. Legal firm McCarthy Tetrault notes the government has made “noteworthy headway” stabilizing the macroeconomy and boosting investor confidence in the 18 months since Milei took office. The cornerstone RIGI incentive regime, extended to July 2027, delivers 30-year tax, customs and foreign exchange stability for qualifying $200 million-plus projects. It has already received or approved $50.7 billion in mining project filings, paired with congressional legislation opening high-altitude areas to mining to remove barriers for global firms.
Global mining giants are already moving in: McEwen Copper is securing $4 billion for its Los Azules project; First Quantum is advancing its $3.5 billion Taca Taca development; and Glencore is seeking RIGI benefits for two copper projects with combined capital expenditure exceeding $13 billion.
The copper rush has also made Argentina a focal point of great-power rivalry. “Argentina is aligning more visibly with Western financing and strategic coordination, especially through its framework with the United States, but it is not stepping away from China,” said Ed Zamanillo and Marta Rivera, co-founders of Geopolitical Mining. Chinese firms including Ganfeng retain a significant footprint in the country’s mining sector. “For Argentina, and for other mineral rich countries, the key is not to choose one bloc over another, but to use this competition to attract investment, accelerate projects, and move further along the mining value chain,” they added.
Significant risks remain. Environmental protests over threats to Andean freshwater reserves have intensified, with a recent week-long court suspension of BHP and Lundin Mining’s Vicuña Corp joint venture highlighting how local disputes can disrupt major projects. Analysts warn the biggest blind spot is Argentina’s federal structure, which gives provinces full control of natural resources. “Foreign mining companies often fail when they treat Argentina as a single jurisdiction,” said GEM Mining Consulting CEO Juan Ignacio Guzmán. “The biggest risk in Argentina is assuming the national picture tells the full story,” added Verisk Maplecroft’s Mariano Machado, noting provincial politics, uneven enforcement and community opposition can derail projects even with national policy support.
For Argentina, the copper boom offers a generational chance to reset its economic trajectory. Its ability to turn short-term momentum into long-term, cross-cycle growth will determine not only its top 10 producer goal, but also its role in the global critical minerals supply chain for years to come.
