TERTIARY MINERALS PLC

("Tertiary" or "the Company")

 Notice of General Meeting - Wednesday 24 March 2021

Tertiary Minerals plc, the AIM traded company building a multi-commodity project portfolio announces that it is holding a General Meeting on Wednesday 24 March 2021. The business of the General Meeting will be to consider and, if thought fit, to pass a special resolution to empower the directors to disapply the pre-emption rights in respect of those shares that were authorised for issue by Shareholders at the Annual General Meeting of the Company held on 28 January 2021 ("the AGM").

Having raised capital recently, as announced on 26 January 2021, the Company has no immediate plans to issue new securities.

However, a resolution to disapply pre-emptive rights has been approved at all previous Annual General Meetings but failed to pass at this year's AGM. Given that only 4.25% of shares then in issue were voted at the AGM, the Directors are of the view that the wishes of the Shareholders as a whole may not have been properly represented and would like to give Shareholders a second opportunity to consider granting this authority.

The Board considers that this resolution is in the best interest of the Company's shareholders and the Company as a whole. Accordingly, the Board unanimously recommends that Shareholders vote in favour of the New Resolution, as they intend to do so in respect of their own beneficial holdings of Ordinary Shares which amount, in aggregate, to 15,579,080 Ordinary Shares representing approximately 1.32 per cent. of the total issued share capital of the Company as at today's date.

A circular and Notice of General Meeting has today been posted to shareholders.
