A couple weeks ago, Sweden's state-owned mining company, LKAB, made a big announcement.

A Swedish mining company says it's found Europe's largest-to-positive rare earth elements.

Rare earths?

Something called rare earths.

Rare earths are used in a wide range of products, including iPhones.

The valuable metals are also key and renewable technology, like wind turbines and electric

cars.

The deposit is a source of hope for the West, because the minerals could help speed up Europe's

path to clean energy.

The rare earth deposit is buried in Sweden's northernmost town, Karuna.

Our colleague Kim McGrail traveled to this town in the Arctic Circle to check it out.

It's about 5.40.

The pitch black here has been very dark for several hours, actually, because the sun

here only is up for a couple of hours.

When I walk, I can hear this snow sort of squeaking beneath my boots.

It's the ground everywhere here.

It's covered in snow.

Karuna may be home to perhaps the largest rare earth mineral deposit in Europe, but mining

that deposit is facing a challenge.

So there's a group of people that are very unhappy about this.

Sweden's saw me people.

They're indigenous people in northern Sweden.
