Operational Update Re: Coronavirus

5th February 2020

Further to the announcement made by Griffin Mining Limited ("Griffin" or the "Company") on 29th January 2020 concerning operations at the Caijiaying Mine, Chinese Government decrees have now restricted all non-essential businesses activities until 9th February 2020 as efforts are made to contain the Coronavirus outbreak in China.

As advised in the previous announcement, pursuant to past normal operational practices, mining operations were suspended at the Caijiaying Mine during the lunar Chinese New Year festivities with effect from 22nd January 2020, whilst milling operations continued until the 30th January 2020.

Underground workings at Caijiaying are being maintained on a care and maintenance basis with essential services, including pumping and ventilation, ongoing. As planned, the opportunity has been taken to undertake maintenance work at the mill, which has now been completed and the mill placed in care and maintenance. Whilst all essential and senior Chinese staff remain at Caijiaying, all non-essential local staff have been sent home and placed on standby with the expectation of operations recommencing on 9th February 2020 as mandated by the Chinese authorities.
