I tried to figure out what those yellow and orange documents are on their website:



Looks like a property deed or title. I think they own the documents show that someone owns a gas station, a car wash, some shed or one car garage, some old industrial buildings, a swimming pool, some land (but doesn't seem to be a mine) and the others are too blurry to make out. It's kinda bizarre that they have these high-resolution scans of their restaurant-becoming-a-coal-mine registration document but the scanner appears to have broken down when they got to the property documents.

Location of the above object:

Edit: the names on the documents don't seem to match any of the principals so it's unclear who owns what.
