National Taiwan University Professor of Geography Chang Shi-chiao, who has already been in the mining area twice, points out that because the veins in that area are not visible on the surface, if you want to mine them it would be necessary to cut open the mountain. "Unless there's gold in there, it really makes one wonder whether it is worth stripping away the land."
進過礦區兩次的台大地理系教授張石角也認為，由於當地礦脈並未露出地表，若要開採，一定得把山剝開；「除非裡面是黃金，否則是否值得剝土開礦，令人懷疑！」
