Usually do an annual trip to Cadia to look at all the big Tonka toys and giant ball mills - kids love it. They used to have a huge chunk of ore at the front steps to the admin dongers which was covered in reall nice pyrites. We would 'sample' the ore, take it back to the lab, crush it, roast it, add sulfuric and then evap to get the copper out.
