Chinese Communist Party's 20^th Congress

Cessation of Explosives Production & Delivery

Consequential Production Shutdown

20^th September 2022

Griffin Mining Limited ("Griffin" or the "Company") announces, following the press release of the Chinese Politburo on the 30^th August 2022 that the Plenary Session of the Communist Party Central Committee will begin on the 9^th October 2022, followed by the Chinese Communist Party's 20th Party Congress on the 16^th October 2022, that the Ministry of Public Security has commenced the implementation of severe security measures to ensure the safety of those proceedings, including restrictions on the manufacture and supply of explosives in the 4 major Municipalities surrounding the Beijing area, being Zhangjiakou, Cheng De, Tian Jin and Boa Ding.

Consequently, as the Caijiaying Mining is located in the Municipality of Zhangjiakou, explosives can no longer be acquired or delivered to the Caijiaying Mine. The current inventory of explosives has been exhausted, mining and haulage has decreased and processing and milling is expected to cease on Thursday, 22^nd September 2022. It is expected that full operations will recommence at the Caijiaying Mine on Tuesday 1^st November.

A plenum of the Chinese Communist Party is normally held in October of every year and, as such, the Company plans and budgets for normal disruption to October production. However, this extended period of unavailability of explosives will inevitably have a significant impact on September and October results. Nevertheless, the Caijiaying Mine has increased production over the past quarter at accelerated rates to record levels unseen in the history of the Caijiaying Mine which may offset any prolonged risk to production due to the Congress. 

Additional measures in mine planning and resources have been taken to ensure that the record levels of production return quickly after the disruption has concluded with monthly production rates in the approximately 1.5 million tonne range, on an annualised basis, upon resumption. 

Chairman Mladen Ninkov commented, "It is an unfortunate consequence of the importance of this year's Communist Party's Congress that such strict security measures have been mandated by the Beijing Ministry of Public Security. Nevertheless, the extraordinary efforts of all concerned in reaching a 1.5 million tonne throughput recently, on an annualised basis, from just Zone III, will ensure that the production and financial impact to Griffin will be minimized to the greatest extent possible."
