A Chile Rare Earths Project Wins Its Permit and Courts U.S. Money
SOUTH AMERICA · ECONOMY
Key Facts
—The milestone. Chile’s regulators gave final environmental approval on June 8 to the Penco rare earths project in the country’s south.
—The money. Its developer, Aclara Resources, is in talks with a US government agency to help finance the mine.
—The template. The plan copies a $5m arrangement the same agency struck for Aclara’s project in Brazil.
—The point. The goal is a rare earths supply chain outside China, which dominates the global market.
—The chain. Aclara’s wider $1.5bn plan links mines in Brazil and Chile to a processing plant in Louisiana.
—The catch. The Penco site has faced years of local opposition, and production is not targeted until 2028.
A Chile rare earths project just cleared two big hurdles on the same day: it won the environmental permit it had chased for years, and confirmed it is courting US government money, in a small but telling sign of how the West is trying to loosen China’s grip on critical minerals.
A Chile rare earths project clears two hurdles at once
On Monday, Chilean regulators granted final environmental approval to the Penco project, a deposit in the country’s southern Biobío region developed by the Toronto-listed miner Aclara Resources. The permit had been the single biggest obstacle in the project’s path, and clearing it was the moment everything else became possible.
The same day, Aclara’s chief executive, Ramón Barúa, confirmed the company is in talks with a United States government agency to help pay for the mine. Two pieces of news that on their own would be modest become, together, a notable step, and they point to a much larger contest playing out far beyond one hillside in Chile.
Why rare earths matter so much
Rare earths are a group of seventeen metals that almost nobody talks about yet almost everyone depends on. They go into the powerful magnets that spin inside electric-car motors and wind turbines, as well as smartphones and advanced military hardware, which makes them genuinely strategic rather than merely useful.
The catch is that China dominates the business, especially the tricky step of processing raw ore into the pure materials manufacturers actually need. That dominance gives Beijing real leverage, and in recent years it has shown a willingness to use export controls as a bargaining chip, which is exactly what has the United States and its allies worried.
So Western governments are now hunting for supply anywhere but China, and Latin America, rich in minerals and closer to Washington than Asia, has become a favoured place to look.
How US money fits in
The agency in the conversations is the US International Development Finance Corporation, a government body that backs projects abroad which Washington considers strategically important. Aclara wants to copy a deal it already has in Brazil, where the agency put in $5m at an early stage in exchange for the option to invest more later, and the company says the idea has been received warmly.
What opened the door was a rule change letting the agency fund projects in higher-income countries such as Chile, followed by a critical-minerals agreement the two governments signed in April. As The Rio Times reported at the time, Penco was named then as one of the most likely projects to emerge first under that new partnership, and now it has.
The bigger plan: mines here, processing there
Penco is one piece of an ambitious, multi-billion-dollar strategy. Aclara intends to feed ore from its mines in Brazil and Chile to a dedicated separation plant it is building in the US state of Louisiana, creating a supply chain that runs from Latin American soil to American factories without passing through China.
The company is targeting the start of production in 2028 and has been talking to carmakers in the United States, Europe, Japan and South Korea about buying the magnets its materials would help make. If it works, a quiet corner of Chile would become a small but real link in the West’s effort to build an alternative to Chinese supply.
Not a done deal
A note of caution is in order, because the environmental permit clears a path rather than guaranteeing the destination. The Penco site has drawn years of opposition from residents and local officials in Biobío worried about health and the environment, and that resistance has not simply vanished with one approval.
The financing talks, too, are still talks, and the agency has declined to comment on any specific project. For now, the honest summary is that a long-stalled mine has its best opening in years, with real money and real demand lining up behind it, and a few real obstacles still to clear.
Frequently Asked Questions
What just happened with the Chile rare earths project?
On June 8, Chilean regulators gave final environmental approval to the Penco project, and its developer Aclara Resources confirmed it is in talks with a US government agency to help finance the mine.
Why does the United States want to help fund it?
China dominates rare earths, especially processing, and has used export controls as leverage. Washington wants supply from elsewhere, and Latin America is a favoured source close to home.
What is the bigger strategy?
Aclara’s multi-billion-dollar plan links mines in Brazil and Chile to a processing plant in Louisiana, aiming to build a rare earths supply chain that avoids China. It targets production in 2028.
Is the mine certain to go ahead?
Not yet. The Penco site has faced years of local opposition in Biobío, the financing remains under discussion, and production is not expected before 2028.
