Notice of Resignation of Managing Director

Tertiary Minerals plc, the AIM traded company building a multi-commodity project portfolio, wishes to advise that it has today received notice from Mr. Richard Clemmey of his resignation as Managing Director of the Company.

Mr. Clemmey will continue in his position until 30 June 2020 to manage the upcoming drill programme on the Company's exciting Pyramid Gold Project in Nevada, USA and to ensure an orderly transition of responsibilities. The Company will seek to make a replacement appointment in due course and the Executive Chairman will assume the role of Chief Executive as an interim measure, if so required.

Commenting today, the Executive Chairman, Mr. Patrick Cheetham, said "It is with regret that the Board has accepted Ric's resignation but understands his decision given that recent events on the Storuman project in Sweden have shifted the Group's focus to its gold and other exploration and resource identification projects. We wish Ric every success in his new role and thank him for his contribution to the Company."
