Reference information

Comments During the 1970s and 1980s, the Voia deposit was the target of exploration activities. In the early 2000s, European Goldfields did geologic mapping and soil geochemical surveys on the Voia porphyry system. According to European Goldfields in the early 2000s, the Voia project did not have proven or probable reserves as its proposed programs were an exploratory search for those resources. The Voia porphyry copper deposit is hosted in a Neogene andesitic plug. Metalliferi Mountains.
