Reader's View: Mine metals we all need in own backyard

Did you know that more than 1 million joint replacements take place each year in the United States? And that number is expected to grow to more than 4 million in fewer than 20 years? And that more than half of those people will be under the age of 65?

I didn't either until I needed a total shoulder replacement. Then I did some research.

Various metals are involved in joint replacements, including stainless steel, titanium and titanium alloys, cobalt, chromium, tungsten, nickel, and molybdenum.

And it turns out we have a lot of these metals right in our own backyard in the Duluth Complex. The Duluth Complex is one of the world's largest undeveloped mineral deposits — yes, one of the world's largest. And it's right here in Minnesota. Talk about buying local!

We also have the third-largest nickel deposit in the world — also right in our backyard. And the second-largest copper deposit is here too.

Most people know someone who has had a joint replacement. And of course we all have cell phones that require most of these precious metals, too.

Why not mine those metals here, close to home, where mining was invented and where we know how to do it right?
