Hey Karell,
Well, I can't speak for what the website states as I haven't taken the time to look through all of the text on it, but the mine tours concluded as of Labor Day weekend, just as in years past. We are running 3 trains daily during the week, and 5 trains daily on the weekends. Our last day of operation for this season is Sunday, October 8.
I have had many passengers ask me why the mine tours are stopped before we stop running the trains. I wish I knew the answer to that question, because I just have to tell them, "I don't know"
