Mostly true, but there are wet mines. My company used to have one on the East Coast of Canada that literally went out underneath the Atlantic Ocean. They were under the ocean!

The rock was very cool, so all humidity coming in on the fresh air formed as condensation on the walls, creating a wet mine.
