Knowing the grades of target elements within an explored region is a very important aspect. Such grade value properties and the element correlation is also the most important exploration parameters needed for any one who attempts to decrease the exploration cost and also the exploration risk. These could be achieved by sampling, laboratory analyses and core loggings within the boreholes. Becaus...

In the Buchim porphyry copper deposit, we determined several representative rare mineral phases, comprising metals from gold-palladium group as well those bismuth-selenium (Cu-Bi-Se-Te-As) group. The phases are represented by new in bismuthinite, galenobismutite, krupkaite, friedrichite, emplectite, laitakarite and native bismuth of gold-palladium, including gold palladium with their elemental ...
