‘Geoforensic Passport’ To Validate Origin of Doré

The University of Lausanne and Swiss refiner, Metalor, announced at the LBMA’s Ninth Assaying and Refining Digital Conference that they have developed a ‘Geoforensic Passport’ – a breakthrough scientific approach that validates the origin of doré received by refineries. This project was co-funded by the Swiss Government through Innosuisse, together with Metalor Technologies.

The process allows refiners to systematically analyse the DNA of every shipment of doré, determine if its origin corresponds to its stated source, detect any inconsistencies and identify gold of dubious origin. This approach is now routinely used at Metalor to scientifically confirm the origin of the doré received at its refinery.

The presentation was delivered by Dr Barbara Beck (Lecturer, University of Lausanne) and Dr Jonathan Jodry (Head of Laboratories & New Business Development, Metalor Technologies) and moderated by Stewart Murray (GDL consultant, LBMA).
