Charles Bray, Chairman of Aterian, commented: "I am very pleased to announce Luke's appointment to our senior management team and take this opportunity to welcome him to the Company, as we enter a new and exciting period for the Company. The recent acquisition of the copper-silver and base metal assets in Morocco, together with the move to the Standard List of the London Stock Exchange will present opportunities in which Luke's skill set will provide significant added benefit to the Company. His intimate understanding of Rwanda and its mining sector will serve us well as we continue evaluating our tantalum-niobium-tin projects in the south of the country and the metals trading business. We look forward to Luke putting his technical expertise to use to prove up our existing assets and working to support the Company's long-term sustainable development.'' - ENDS This announcement contains information which, prior to its disclosure, was inside information as stipulated under Regulation 11 of the Market Abuse (Amendment) (EU Exit) Regulations 2019/310 (as amended).
