Wouldn't you still have to have surface rights because you need an entrance to the bunker? The headline seems quite misleading then, a guy named Craig will only have control over the mineral rights of the land. Can oil companies drill without also having surface rights? Generally they need to build a structure to collect the oil.
The owner or lessee for mineral rights has the right to access them. So they can build structures, roads, etc. This is one reason why landowners typically work with mining/oil companies, because the company could just choose to put their well in your backyard if you won't work with them.
