Reference information

Comments Reserves are 27 Mt at 1 g/t Au and 0.26 percent Cu. The deposit is hosted in quartz andesite that penetrates volcanic rocks in a subvolcanic setting. Lips (2006) characterizes Valea Morii as an old mine on an abandoned deposit. Metaliferi Mountains.This porphyry Cu-Au-(Mo) deposit is genetically related to porphyry andesite-microdiorite calc-alkaline subvolcanic bodies.
