At the Rosia Poieni porphyry copper deposit, Romania.   The recently privatised Rosia Poieni porphyry copper mine is located 4 kilometres ENE of the older epithermal Rosia Montana gold deposits. The group was given an overview of the mine, its geology and the extent of the orebody, and then the opportunity to study host rocks, alteration and ore in the pit.
