UK research to benefit Australian copper
By Samantha James RESEARCHERS in the UK have discovered a new way to find large copper deposits by identifying chemical markers in porphyry rock. A study co-authored by University of Exeter geologist Dr Ben Williamson detailed a new chemical exploration tool that could be used to find porphyry-type copper deposits. These low quality but high quantity deposits are the most common copper deposits in the world, delivering about three quarters of global copper. Dr Williamson said the new technique would be the least expensive method of retesting core samples for copper and reassessing explored land. “We’ve compared the composition of that mineral between magmatic rocks that do form these deposits and those that don’t, and we’ve found there’s a chemical…
