Bring your own
I did not have a mount on the helmet they provided for me. I cannot speak to all their helmets, but it's probably best to just bring your own. I wouldn't just bring a mount because it is highly unlikely they will allow you to affix it to their helmets.
Some do , most don't. I reccomend bringing your own.

Yes they have mounts
You have to bring your own helmet if you want to run a gopro
