Porphyry-style Cu-Au and magmatic Fe-Au ore bodies. The Cu-Au ore bodies are hosted in quartz-albite porphyry intrusions. Ores consist of quartz-sulphide veinlets in the upper parts and disseminated mineralizations in the lower part of the intrusions. Some of the iron-rich zones are associated with gossan resulting from surface weathering of sulphides in porphyry Cu-Au deposits, but there are also some veined Fe ore bodies that are characterized by distinct intrusive features.
