Dowa Metals & Mining Co Ltd and Korea Zinc - Conclusion of IRP

As the Independent Authority for Precious Metals, LBMA maintains the highest standards for responsible sourcing. It, therefore, is committed to ensuring that the origin of material is such that it maintains the integrity of LBMA’s good delivery status. The focus of the Incident Review Process (IRP) was to ensure that the concentrates sourced by Dowa Metals & Mining Co Ltd and Korea Zinc Co., Ltd maintained that integrity.

As an iterative process, this IRP has involved extensive discussions with the refiners and external counsel.

Following the conclusion of this IRP, both entities remain Good Delivery List Refiners. LBMA did not find any instances of zero-tolerance non-conformance.


The London Good Delivery List of Acceptable Refiners of gold and silver is maintained by LBMA, by whom it is copyrighted. It lists those refineries whose gold and silver bars have been found, when originally tested, to meet the required standard for acceptability in the London bullion market.
