In April 2023, Chile’s authorities accepted the extension of Los Bronces, a serious copper mine close to the capital, Santiago, after having rejected it final yr over environmental issues.As a part of the accepted plan, Anglo American, the bulk proprietor of Los Bronces, has dedicated to changing 70,000 wood-burning stoves utilized in households throughout Santiago with electrical burners — however critics say that is unrealistic.The mine extension venture faces a backlash from environmental activists and native and regional authorities, who say they plan to take the matter to court docket.They cite potential impacts to air high quality, in addition to mud air pollution that might darken glaciers within the area and pace up their melting, thus threatening a key water provide for Santiago residents.
Macarena Martinic wasn’t stunned earlier this yr when the Chilean authorities mentioned sure to extending the lifetime of Los Bronces, a big, centuries-old open-pit copper mine within the Andes, an hour’s drive from the capital, Santiago.
“Per week earlier, Chilean Economy Minister Nicolás Grau talked about how essential the mine was to the Chilean financial system,” says Martinic, a lawyer with FIMA, an environmental NGO. “To be honest, we already felt the storm coming. Nevertheless, I used to be very upset. This approval is an enormous contradiction in what this authorities initiatives.”
Los Bronces was found and first exploited in 1867, when the mountainous area lacked satisfactory infrastructure, and the expertise to extract minerals from the bottom was restricted. In the early twentieth century, mining operations took off in earnest, turning Los Bronces into one in all Chile’s largest copper mines, at the moment producing practically 330,000 metric tons of the metallic per yr.
In May 2022, the Environmental Evaluation Service (SEA), the Chilean authorities’s environmental regulator, decided that new plans by Anglo American, the U.Okay.-headquartered mining large with a majority stake in Los Bronces, would threaten the well being of residents of surrounding areas. It rejected Anglo American’s plans to increase its operations, warning that air high quality can be severely impacted by mining and that surrounding glaciers may soften sooner due to snow air pollution.

In response to the company’s rejection, Anglo American introduced that it could provide you with new plans to scale back the mine’s environmental influence and guarantee it may proceed its extension plans. Less than a yr later, a committee of ministers, together with Chile’s setting minister, determined {that a} allow can be allowed for the $3 billion extension venture. The mine ought to stay open till a minimum of 2036.
The authorities additionally mentioned it had determined to approve the extension of Los Bronces whereas imposing excessive environmental requirements that the mine must adjust to to guard human well being, alongside strict monitoring and management of water sources, protected species, and the glaciers neighboring the venture.
Government flip-flop
When the federal government rejected the mining extension in 2022, Anglo American had already promised to scale back the mine’s influence. It mentioned that greater than 30 kilometers (19 miles) of grime street can be paved, cash can be invested in environmental facilities (though there are not any particulars on what these would entail) and an adjoining nature reserve, and $120 million can be put aside for dozens of electrical automobiles to move mine employees.
In the newly accepted proposal, Anglo American promised to put in electrical heaters to interchange as much as 70,000 wood-burning stoves in houses in Santiago. At an estimated whole value of $85 million, to be borne by the mining firm, this effort goals to enhance air high quality in one of the crucial polluted cities in South America.
The plan to fight air air pollution was additionally one of many causes for approving the venture, in line with Marcela Hernando Pérez, the minister for mining. Speaking on the International Copper Conference in April, she additionally identified the financial advantages: “This is sweet information for the financial system and for employment, because it entails an estimated funding of $3 billion and can create greater than 5,000 jobs. The approval of this venture with the demanding circumstances imposed will enable us to reconcile financial improvement and environmental safety.”

Pamela Poo, a public coverage director on the Ecosur Foundation, an environmental nonprofit, suggests it’s this latter, financial, cause why the extension was accepted.
“The first issue is that not too long ago a serious tax reform was rejected,” she tells Mongabay. “I believe the federal government began trying to find funding and mentioned, ‘Let’s have a look at revenue by way of extractivism.’”
“Second is the worldwide demand. The Global North seeks extra carbon neutrality in its personal industries. But which means they begin taking a look at different international locations for his or her minerals. This inexperienced capitalism means they’ll drain copper from Chile till the final drop,” she says.
An absence of compromise by the federal government was additionally an element, in line with Poo: “You can current your self as an ecologic authorities, however fact is, that’s inconceivable in a rustic with so many minerals.”
According to Poo, the plans to interchange tens of hundreds of wood-burning stoves isn’t sensible.
“I actually don’t imagine this can occur,” she says. “Not as a result of the corporate can’t [afford to] do it — they clearly have the means. The subject is, how do you persuade folks to modify from firewood to fuel or one thing electrical. Apart from the traditions folks have, they’ve power payments to pay. Who’ll maintain that?”
Glaciers and water provides in danger
Los Bronces sits within the neighborhood of main glaciers that present a lot of the clear water for residents of Santiago and its surrounding areas. The revised plans for the mine name for alarm programs to forestall harm to glaciers, one thing Camilo Rada, a glaciologist on the University of Magallanes, says he’s undecided about.
“It sounds good, a system that points early warnings. But how will it work? What if we’re above alert ranges? All these particulars are lacking,” he says.
To Rada, himself an avid mountaineer, the federal government underestimates how essential glaciers are to Chile, particularly within the central areas of the nation, affected by an ongoing drought.
“Glaciers are like a financial savings account: they save water,” Rada tells Mongabay. “Chile has very marked seasons. When it rains within the winter, it falls as snow on the glaciers. The water will get saved within the mountains because it turns into ice. Then in the summertime, when it’s dry and heat within the capital, glaciers launch water. And given the mega-drought we now have in Chile, these glaciers are important.”

Rada factors out that the largest influence of Los Bronces is tough to measure within the quick time period. That’s the large quantity of mud that comes from open-pit mining, which, after they choose glaciers, can pace up their melting.
“Glaciers have what we name an albedo, which implies that a certain quantity of photo voltaic radiation reaching glaciers will get largely mirrored [away] due to the white snowcaps,” he says. “But mud emissions darken the glaciers across the mine, that means extra radiation will get absorbed, inflicting the glaciers to soften sooner.”
Vowing to wage a authorized battle
In response to the venture’s approval, a number of environmental organizations say they’ll pursue court docket motion to reverse the federal government’s determination. Local and regional authorities, together with Claudio Orrego Larrain, governor of the Santiago metropolitan area, have additionally declared their opposition to the venture.
The Chilean authorities declined to remark to Mongabay on the problem.
Martinic, the environmental lawyer, says the battle is way from over.
“We will take this so far as we will, from environmental tribunals to the Supreme Court. So we nonetheless have a protracted approach to go,” she says.
She provides the problem of Los Bronces ought to be seen as each an finish and a starting level.
“I believe the present local weather disaster, particularly in one in all Chile’s most populous areas, requires political selections which are extra in keeping with the scenario we face,” Martinic says. “That means wanting extra carefully on the long-term penalties of such initiatives, and daring to say ‘no’ to initiatives with a huge impact.”
