What Makes for a Copper Porphyry Takeover TargetPorphyry geology Wikipedia

Major miners look to copper porphyry deposits for large tonnage low cost operations We take a look at what makes for a copper porphyry takeover target Ask any economic geologist the most The term porphyry is also used for a mineral deposit called a copper porphyry The different stages of cooling that create porphyritic textures in intrusive and hypabyssal porphyritic rocks also lead to a separation of dissolved metals into distinct zon This process which occurs primarily when fluids are driven off the cooling magma is one of the main reasons for the existence in the
