24/06/2016· A by product of molybdenum, which is itself a by product of the mining of copper porphyry ores, Rhenium is also sometimes found within sedimentary copper ores. Its main recovery occurs where copper is mined along the Pacific fault, which stretches from the southern tip of Chile, north through Peru, New Mexico, and along the Rockies.
It consists of low grade copper molybdenum gold mineralisation in four zones namely Catalina, Isabela, 281 and 285.The mine is a typical porphyry deposit located within the Late Eocene to Early Oligocene Metallogentic Belt. The deposit is hosted by andesites, rhyolites and sedimentary rocks.Mineralisation can be classified into three types: hypogene sulphides or primary minera
