Incredible time hiking the Mary Murphy, but do you know where the real entrance is?

We hiked up the Mary Murphy today and saw the tram house and then a bit of the way to Pomeray because I saw a picture of the mine entrance (with metal bars blocking it) and we were hoping to see it but had no luck. We turned around and looking it up doesn't really tell me anything but I was wondering if somebody knew more about the actual entrance and how we would have gotten there. The website I saw them on says they're taken in 1999 and captioned "Near Mary Murphy - Mine Entrance" I was wondering if these are actually the entrance or if anybody knew where the actual mine was, and how we would have gotten there?
