update to Share Buy Back Programme

12^th APRIL 2024

Further to the announcement of 26^th February 2024 in which Griffin Mining Ltd. ("the Company") renewed its Share Buyback Programme, the Company announces that it has entered into an irrevocable commitment with its corporate broker Panmure Gordon (UK) Limited ("Panmure Gordon") to manage the Share Buyback Programme on its behalf, repurchasing the Company's ordinary shares from 12^th April 2024.

Panmure Gordon will make trading decisions in relation to the buyback of ordinary shares independently of the Company. The Company confirms that it does not consider itself to have any inside information at present. The parameters of the Share Buyback Programme regarding price and volume remain unchanged; the Share Buyback Programme will be carried out on the London Stock Exchange and will be effected within the safe harbour provisions set out in the Market Abuse Regulation 596/2014 ("MAR"), the Commission Delegated Regulation (EU) 2016/1052 and the applicable laws and regulations of the London Stock Exchange.

The Company will make further regulatory announcements in respect of repurchases of ordinary shares as required by UK MAR and the AIM Rules, including as to whether those shares will be cancelled or are to be held in treasury.

In addition to the Share Buyback Programme, the directors continue to reserve the right (subject to compliance with applicable law) to:

1.   purchase large blocks of shares from individual shareholders where the large number of such shares offered in the market may cause instability in the Company's share price; and

2.   purchase a larger number of shares via a tender offer which would be the subject of further documentation being sent to non-US resident shareholders.
