Confinement of Joint Venture Director

15th December 2023

Griffin Mining Ltd ("Griffin" or the "Company") has been informally notified by a member of the Supervision Committee under the Supervision Law of the Peoples Republic of China (the "Committee"), that Mr Shengchang Jin ("Mr Jin"), a director of Hebei Hua Ao Mining Industry Company Limited ("HHA"), the 88.8% owned operating subsidiary of the Company, has been placed under hotel detention whilst the Committee investigates his actions in relation to his employment as the Chief Executive Officer of Zhangjiakou Yuanrun Enterprise Management Consulting Service Co. Ltd, the minority 11.2% shareholder in HHA. The current ongoing investigations only relate to Mr Jin and do not concern HHA's operations or any relevant statutory licenses issued by the government.

While the investigations have not yet come to a conclusion, the investigative team has acknowledged and thanked HHA for its full cooperation to date. Nevertheless, the investigation remains ongoing and there is no certainty as to its final conclusions and if any alleged conduct by Mr Jin may in some manner have involved his time and/or efforts as a director of HHA. The Committee operates in secret and public disclosure of its findings may or may not occur at the Committee's discretion.
