Approval of Caijiaying Zone II Mine Plan

6th March 2023

Griffin Mining Limited ("Griffin" or the "Company") is pleased to announce the approval, by the Hebei Provincial Emergency Response Bureau, of the Mine Design for Zone II of the Caijiaying Mine, including the expansion of the production throughput rate.

The infrastructure included in this design will be in operation for the duration of the mine life at the Caijiaying Mine. Based on the known published mineral resources as classified by JORC, Zone II will be in production for over 25 years and contribute 23.98 million tonnes of ore, being 59.3% of the projected total ore to be produced on the current life of mine plan for the Caijiaying Mine. Construction at Zone II will commence immediately with horizontal underground development having already begun. 

Chairman Mladen Ninkov commented, "As has been the case throughout the history of the Company and the Caijiaying Mine, the Company has continued to successfully navigate the Chinese regulatory environment to obtain all the necessary approvals and licences to allow the Company to thrive and expand. Congratulations to all those who contributed so tirelessly to this success."
