I don't hold any stock & don't really have an opinion on the comapny or Mt Mulligan but it's also worth remembering that being a National Park doesn't neccesarily put an end to any future mining although any that does occur within the park will have much tighter regulations.
Rio Tinto - Marandoo (iron ore) Karijini National Park WA 1994 - present
Energy Resources of Australia - Ranger (uranium mine) Kakadu NT - 1981 technically not in the NP but completely surrounded by it
