Aterian Plc announced the sale of its portion of the Net Smelter Return Royalty over the HCK Project in the Republic of Rwanda ("Rwanda") for a £200,000 gross consideration. The Company has signed an agreement to sell a interest of 1.40% of the Rio Tinto Joint Venture NSR to Elemental Altus Royalties Corporation ("Elemental Altus"). This royalty reduces to 1.25% upon the Musasa licence being issued in Rwanda.

The Company engaged strategic advisors, Collingwood Capital Partners AG, to approach several royalty companies to gain expressions of interest in purchasing the NSR and to provide third-party oversight in the sale of the NSR to Elemental Altus, who provided the best option for the Company.
