- The destructive legacy of mining often lingers for communities and ecosystems long after the operating companies leave.
- Several large, multinational mining corporations have scrubbed their images — touting their commitments to sustainability, community development and action on climate change — but continue to deny accountability for the persistent impacts of mining that took place on their watch.
- A new report from the London Mining Network, an alliance of environmental and human rights organizations, contends that these companies should be held responsible for restoring ecosystems and the services that once supported communities.
The scale of excavation for copper and gold in the 1970s and 1980s at the Panguna mine, then one of the world’s largest open-pit mines, was massive: It swallowed up surrounding tracts of forest and farmland and wiped out wildlife populations on the island of Bougainville off the coast of Papua New Guinea. The company that operated Panguna, a predecessor of London-based mining giant Rio Tinto, dumped the mine’s contaminant-loaded wastewater into local streams for more than a decade and a half, killing off fish and rendering them too polluted for human use.
Neither the Papua New Guinea government nor the company stepped in to protect the environment, even after local communities, reeling from the impacts, sounded the alarm on the mine’s effects on their health, lives and livelihoods. Those tensions festered, and soon a war for Bougainville’s independence began. Fighting throughout the 1990s killed some 20,000 Bougainvilleans, and though a 2001 peace treaty granted Bougainville a measure of autonomy, the effects of the conflict and the mine still linger.
The company abandoned the mine in 1990, leaving it under the control of the Bougainville Revolutionary Army, and in 2016, Rio Tinto officially handed over its shares in the mine to Papua New Guinea and Bougainville.
“There is, in my personal view, an obligation of Rio Tinto to come back and to contribute to cleaning up the mess they left behind,” Volker Boege, who has studied the conflict and co-directs the Peace and Conflict Studies Institute Australia in Brisbane, said in an interview. “The effects of mining will be with the people on the ground long after [the] mining ceased.”
Holding Rio Tinto and other corporations accountable once they’ve relinquished their control of mines remains a difficult task, according to a new report published Feb. 19 by the London Mining Network, a consortium of environmental and human rights groups.
Rio Tinto said in a 2016 letter written by a company executive that the operation of the Panguna mine “was fully compliant with all regulatory requirements and applicable standards at the time.” But for Boege, who wrote the case study on the Panguna mine included in the London Mining Network report, that assertion doesn’t address the company’s ethical responsibility.
“I think it’s not good enough to just say, ‘We followed the legal obligations of the early 1970s or late 1960s,’” Boege said, “because everybody knows that this enables this kind of environmental destruction that people are suffering from even today.”
The report details lays out similar stories throughout Oceania and Southeast Asia. In western Papua New Guinea, BHP, a mining company with headquarters in Melbourne and London, elected to go with riverine tailings disposal — the same waste management strategy that polluted waterways around Panguna — for the Ok Tedi mine, a gold and copper deposit that BHP excavated until 2002. Situated amid forested mountains, the mine has been blamed for a 95% drop in fish numbers in the Ok Tedi River and degrading 2,000 square kilometers (772 square miles) of forest. Researchers figure that Ok Tedi has affected the livelihoods of around 40,000 people who depend on fishing, hunting and gardening.
Hannibal Rhoades, head of communications for the London-based NGO Gaia Foundation, said that companies like BHP often lobby governments for less stringent regulations. In Ok Tedi’s case, BHP persuaded the government to go along with riverine tailings disposal in the early 1980s.
Papua New Guinea, like many resource-rich countries, has struggled to develop economically. As a result, leaders are often amenable to legal conditions favored by the company so they don’t lose a possible source of revenue.
While that’s a familiar pattern, said Rhoades, who wrote the Ok Tedi case study, it shows that governments too must be held accountable for protecting their citizens and the environment.
In addition to the companies’ role, he said, “It’s a game of power influence at the state level.”
Across the border in Indonesia’s half of New Guinea Island, the massive Grasberg gold and copper mine sidles up to the flanks of some of the region’s tallest mountains. Nearby, rare (and shrinking) equatorial glaciers cling to the summit of Puncak Jaya, towering 4,884 meters (16,024 feet) above sea level.
Still in operation today, the mine pumps an estimated 200,000 metric tons of waste into the Ajkwa River every day, contaminating a source of drinking water for local communities. Rio Tinto had been involved in the mine from 1996 until 2018, when it sold its stake to Indonesia’s state mining company, PT Indonesia Asahan Aluminium.
An investigation by The New York Times in 2005 found that Rio Tinto’s partner, U.S.-based mining company Freeport-McMoRan, had been paying tens of millions of dollars for Indonesian military and police to protect the operation’s employees. Local residents, such as Yosepha Alomang of the indigenous Amungme people, say that these government security forces in fact were there to deter local communities through intimidation from voicing their concerns.
But Rio Tinto says that when it sold its stake for $3.5 billion in 2018, its responsibility to address the problems for the local environment and communities that the mine has created ended as well, according to a case study written by Andrew Hickman, a researcher with the London Mining Network.
Hickman, Boege and Rhoades agree that challenging such contentions by companies that were once involved is an uphill battle. The success of using the courts varies. Several lawsuits against BHP for its operations of Ok Tedi yielded a settlement with the company, but BHP didn’t stop dumping waste in the river. In 1996, Alomang and other leaders sued Freeport unsuccessfully in the United States.
The London Mining Network advocates for the continued development of a United Nations treaty on transnational corporations that would codify protections for human rights.
Boege said that such “globally applicable guidelines” were necessary. But “they are not a panacea,” he said. “The problems can only be solved in the specific local context.”
Another tactic has been to bring local leaders like Alomang to the annual general meetings of companies such as BHP and Rio Tinto so they can speak with executives and shareholders about the problems their communities face.
Requests for comment from Mongabay to BHP and Rio Tinto went unanswered.
Companies have responded in their approach, however — at least as far as changing the narrative around the impacts of resource extraction. Rio Tinto, for example, says that a future “low-carbon economy” will rely on the minerals it produces, and touts its moves toward carbon neutrality in its operations.
Hickman calls such moves to scrub a company’s image “window dressing.” He also said that, when confronted with the testimony of leaders such as Alomang, these companies “have learned to be polite, but underneath the politeness is a fist of steel.”
That’s because the changes to operations, whether to make them more environmentally friendly or to ensure that communities are better informed, often lag behind the rhetoric put forth, the Gaia Foundation’s Rhoades said.
“It’s great that there’s that narrative and the investors are more active,” he said. But across much of their operations, he said, “their PR still far outstrips the genuine efforts on the ground to change practices.”
