Vancouver, British Columbia--(Newsfile Corp. - June 19, 2026) - Atlantico Energy Metals Corp. (CSE: ATLA) (FSE: 1CJ1) (the "Company" or "Atlantico") announces the appointment of Andrew Lee Smith to the Company's Advisory Board, the commencement of trading on the Frankfurt Stock Exchange under the symbol 1CJ1 and WKN A42CRT, and the expanded launch of the Company's 16-language website at www.atlantico.energy.

Together, these initiatives are intended to strengthen Atlantico's technical foundation, broaden investor access and support the Company's mission of responsibly advancing critical-minerals opportunities in Brazil as it builds toward the next phase of work at Atlantico's flagship Novo Cruzeiro Lithium and Rare Earth Elements Project in the Araçuaí-Itinga pegmatite district of Minas Gerais, a region commonly referred to as Brazil's Lithium Valley.

"Atlantico was built on the belief that responsible mineral exploration is not opposed to a cleaner future; it is essential to achieving one. The world cannot meaningfully reduce its dependence on fossil fuels without new sources of the critical minerals required for electrification, renewable energy, batteries and advanced energy infrastructure," said Bonn Smith, President and CEO of Atlantico.

"Andrew brings the technical, geological and public-company experience we want around the table as we build Atlantico with discipline, transparency and clear intention. Together, our Frankfurt listing and expanded 16-language website reflect the same objective: making Atlantico more accessible to investors and stakeholders around the globe as we advance our flagship Novo Cruzeiro Lithium and Rare Earth Elements Project in Brazil's Lithium Valley."
