ELI5: Explain Like I'm 5

Canadian pipe mine

A Canadian pipe mine is a big, deep hole in the ground where companies dig for precious materials like diamonds. Imagine you're playing in a sandbox and you find a really cool rock. Well, in Canada, they want to find the biggest, coolest rocks possible that are worth a lot of money.

Now, to make this happen, the companies need to use big machines to dig a hole in the ground that is very deep, sometimes even a few kilometers deep! That's deeper than any swimming pool you've ever seen!

Once they reach the right level, they use special tools to dig out the rock that may have diamonds inside of it. These tools sort through the dirt and the rock, looking for shiny rocks that could have diamonds inside.

All this hard work is worth it, though, because these Canadian pipe mines might be one of the only places in the world where these super cool, shiny rocks are found! Pretty neat, huh?
