Aterian Plc
("Aterian" or the "Company")

Aterian Plc (LSE: ATN), the critical and strategic metal-focused exploration and development company, is pleased to announce the appointment of Mr. Luke Rogers to the position of Chief Operating Officer ("COO") as of 1 November 2022.

Luke has over 14 years of international mining experience, primarily focused on base metal projects in developing economies. Luke holds a Bachelor's Degree in Mining Engineering and a Master's Degree in Minerals Engineering from the Camborne School of Mines. He has worked across multiple mining disciplines ranging from production mine engineering to mineral processing operations.

Most recently Luke was Chief Operating Officer of Trinity Metals, the largest tin and tungsten producer in East Africa, overseeing nine mine projects, 4,500 employees and the largest investment ever in the Rwandan mining sector (Trinity Metals is a subsidiary of TechMet, a privately owned technology metals mining company).

Prior to Trinity Metals, Luke was country manager for AMR Gold in Sierra Leone, leading a team of 26 people and helped develop the region's Wilkinson Hill Coltan deposit, building a 'Life of Mine' financial model to establish IRR and NPV data. Luke has had senior management experience at Chepstow International, one of the largest mining contractors in Southwest England, and worked with Glencore in the DRC at the world-class Mutanda Copper-Cobalt mine. As a mining and processing engineering consultant and manager, Luke brings significant and relevant experience to Aterian's African portfolio. 

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.''
