What does a proposed nickel mine near a small town in Minnesota tell us about conflict over critical minerals?
The town of Tamarack, Minnesota, has a population of around 70.
Despite its small size, Tamarack could soon be key to a crucial landmark for climate technology, because Talon Metals wants to build a huge mine outside the town that could dig up as much as 725,000 metric tons of raw ore each year. The primary target is nickel, a metal that’s crucial to building high-performance EV batteries.
Talon has been very explicit in claiming that this mine would have benefits for the planet, going as far as applying to trademark the term “Green Nickel.” That’s one of the reasons this particular site piqued James’s interest, he says.
At the same time, local concerns are growing. Drilling could release 2.6 million gallons of water into the mine every day, which Talon plans to pump out and treat before it’s released into nearby wetlands. This part of the plan has caused some of the greatest unease, since local fresh water is crucial to the community’s economy and identity.
The central tension was abundantly clear on a nearly weeklong trip to Tamarack and the surrounding communities, James tells me. He went to Rice Lake National Wildlife Refuge and learned about native wild rice that grows there and its importance to Indigenous groups. He went to see samples of the ore that Talon dug up and spoke to a geologist about the resources in the region. He also attended community meetings that got a little heated, and even had to contend with some local bees.
“We’re talking about a story of two different, very precious resources that have created a really difficult-to-address conflict,” he says. “It’s a tension that’s ultimately going to be very hard to resolve.”
There are rarely easy answers when it comes to the massive task of addressing climate change. If you’re interested in getting a better understanding of this complicated web of trade-offs, take the time to read James’s story. You’ll get all the details about why this particular deposit is such a big deal, and hear more about where things are likely to go from here.
And the story doesn’t stop there. James also has another big project out this week, in which he worked to understand how this one mine could unlock billions of dollars in government subsidies. Dig into that here.
