Wish the show was real, but it's not. The "Shadows in the Drift" episode sealed it for me. They didn't put a hole through the mountain. It's a set they made at the top of the mountain to look like a portal. If you frame-by-frame through the part where Patrick is about to rappel over the side, the camera pans FROM THE RIDGELINE over to Patrick. Now the location where Ghost Mine was filmed is 44.845678 -118.155152 (which is up near Bourne - nowhere near where they say it is in the show). If you open that up in Google Earth and follow the road to the top of the mountain, you'll see it ends in a flat area. This area exactly matches the location as seen in that shot. There is no "hole" in the back of the mountain. In addition, when Eddie pokes his head out of the "hole" and says he can see Baker City - well, if you take Google Earth to it's ground-level view and look East from that flat area at the top of the mountain, you'll see that this valley matches what Eddie sees EXACTLY. And that area at the end of the valley? Eddie says it's Baker City. But It's Haines - or rather, the farmland to the west of Haines. So the miners are following a script. Combine that with the fact that this mine is definitely not on a straight line between Sumpter and Baker City (so all the talk between Kristen and Patrick about those paranormal straight lines is BS) and the Baker City Herald article that says the claims about the mine being haunted are very exaggerated, and you come to the conclusion that the show is fictional. Knowing that Patrick was a debunker before he came to Ghost Mine (he has said that all SyFy Network paranormal shows are faked), it's probably a case of staging a paranormal show to demonstrate how people are fooled. Maybe that's going to be the final big "reveal" at the end of the show.
So why watch it? Well, it is still entertaining. We watch movies like Paranormal Activity knowing they aren't real. Why not a story about a ghost mine?
BTW, Google Earth shows that most of the Ghost Mine set is still in place. The miners' shacks, the cook shack, the investigator's shack, the main portal, and the collapsed portal are all visible.
