Increase to US$10 Million in Available Funds for Purchase of Own Shares

19th December 2023

Griffin Mining Limited ("Griffin" or the "Company") has previously announced on the 12th September 2023 that it would renew its efforts to effect the buy-back of shares of the Company previously announced on the 25th February 2021 (the "Buy-Back Programme") and to extend the Buy-Back Programme after its expiration on the 25th February 2024 on the same terms.

In addition to the Buy-Back Programme, the directors reserved the right (subject to compliance with all applicable laws and regulations) 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 large number of shares via a tender offer which would be the subject of further documentation being sent to non-US resident shareholders.

In view of the current market price of the Company's shares, the lack of shares capable of being offered daily to the Company under current market regulations and the desire of certain large individual shareholders wishing to possibly sell a large number of such shares which could cause instability in the Company's share price if offered via the current Buy-Back Program, the Company has increased the funds available for the purchase of its own shares from up to $5m to up to US$10 million and an unlimited number of shares in addition to that already expended under the Buy-Back Programme.
