this was a big square building that shined like new tin a light came around it then it went away no sound no flash nothing

My name is ((name deleted)), About 1975, me and a friend came from work to deliver some parts to my mine, we pulled up in the road to unload the parts and out about 150 feet in front of us was this box that shined in my lights, it was like new sheet metal, we looked at it and I got mad for mr. ((name deleted)) had built a building on the fault and my lease gave me no rights to mine under a building, as we were mining in a north direction and the building was north on the fault, pulled up on a little mound of dirt that I had put a 8 in. pipe in for the discharge water from the mine, we could see the building plane as day about 70 ft. by 60 ft. by about 15 ft. tall, we were talking about mr. ((deleted)) and I would get a lawyer in the morning to have him move it, about that time we saw a light come around the building, I shut the truck off and got out to talk to mr. ((name deleted)), the light went around to the left side of the building, so we went toward the building, we were looking at the building and it went away, just like that, it was not their any more.  That is the truth
