Is the mine haunted?

I didn't see any ghosts

Probably

I didn't see feel or hear anything

According to the staff, yes. I went on 2 investigations there and have seen a shadow figure and heard voices, noises on EVPs and without EVP. New Jersey Paranormal does at least 2 investigations there each year. Try to go on one, and decide for yourself😁 or tje mine offers daytime tours..its a pretty spectacular place to visit!
