Renewal of Caijiaying Mining Licence to 2054

Griffin Mining Limited ("Griffin" or the "Company) is delighted to announce that it has successfully renewed its mining licence over the Caijiaying Mine through to the 28^th August 2054. The term of 26 years is based upon the mine resources with the previous licence term being 16 years based upon earlier mineral resource estimates. This is a landmark achievement for the Company and guarantees it's long term mineral rights, it's production envelopes in Zones II and III, it's previously approved mining area and it's vertical mining boundary over the total Caijiaying Mine area.

In addition, the mining licence renewal confirms the continuing successful development of the Caijiaying Mine and the Company's continuing ability to achieve key regulatory milestones in the Chinese regulatory environment. The extended tenure until 2054 secures the long-term future of the asset and allows for the continued systematic extraction of the resource.

Chairman's Statement

Chairman Mladen Ninkov commented, "I couldn't be happier for the Company, the shareholders, the staff and contractors who were able to achieve this critical milestone. As I stated in in the announcement of the 3^rd December 2025, 'It is the Company's continuing support of the Chinese regulatory authorities that engenders the goodwill towards Griffin, as good citizens of China, to obtain the necessary approvals to take the Caijiaying Mine to the next level.' This renewal is a testament to the Company's hard work and strong relationship with the relevant administrative authorities and provides us with the long-term regulatory certainty to continue the development of Caijiaying for decades to come."
