What happens when the gold you can’t see is the gold that matters most? In this deep-dive technical discussion, Dr Simon Dominy, Dr Naomi Potter, and Dr James Tickner explore the critical challenges of coarse gold sampling and analysis — and why traditional assay methods may be under-reporting your grade.
