It’s almost certainly the worst officially-recorded mining disaster in recent Indonesian history. On Tuesday, 21 May 2013, twenty eight mineworker were confirmed dead as the result of a tunnel collapse at Freeport’s Grasberg operations in Papua during the previous week. For the moment we’d like to turn back the page to a strikingly similar ocurrence, a few weeks ago in the United States. In April, a huge landslide destroyed much of Rio Tinto’s massive Bingham Canyon open pit workings in Utah.
