The mines never stop production. It's mostly a 24/7 production across the globe. Getting out on the site at night can yield some amazing photographs, especially the 30 minutes after the sun sets when the warm glow of the sun melts over everything.
Awhile back Atlas Copco consitantly featured companies that were using their ITH drilling prodcuts, in this case Idea Drilling based out of North Virgina. This is a great way to promote your companies product and also show appreciation for your clients.
