NANO Nuclear Signs a Memorandum of Understanding with UrAmerica Ltd. to Help Modernize and Develop Argentina's Nuclear Fuel Supply Chain

New York, New York--(Newsfile Corp. - July 8, 2025) - NANO Nuclear Energy Inc. (NASDAQ:NNE) ("NANO Nuclear" or "the Company"), a leading advanced nuclear energy and technology company focused on developing clean energy solutions, today announced that it has signed a Memorandum of Understanding (MOU) with UrAmerica Ltd., a private exploration company with a package of uranium and other critical metals licenses primarily in Chubut Province, Argentina.

The newly signed MOU formalizes the discussions that NANO Nuclear initiated with UrAmerica to explore strategic development across Argentina's uranium-fuel supply chain. Both companies are now working to evaluate specific opportunities, ranging from mining and conversion to UF₆ feedstock supply, that could aid NANO Nuclear in securing a dependable source of material for future supply chain options. Such evaluations may lead to the signing of definitive agreements between NANO Nuclear and UrAmerica related to particular projects.

Argentina has one of the largest uranium repositories in the world and its government is currently looking into the privatization of their nuclear energy sector, enabling innovators like NANO Nuclear to invest and support the development of the nuclear energy infrastructure in the country. Through this MOU, NANO Nuclear and UrAmerica aim to build the mining and milling capacities of the uranium supply chain in Argentina with the intention to be a part of the uranium fuel cycle exports into the U.S.

Under the MOU, the companies will pursue (i) favorable uranium offtake agreements, (ii) potential investments in mineral production and (iii) fuel-cycle infrastructure, and (iv) future joint ventures or related collaboration. One of NANO Nuclear's goals in entering into the MOU is to help modernize Argentina's nuclear sector while strengthening U.S. energy security by sourcing materials for nuclear fuel from a reliable partner.

"We are pleased to formalize our discussions with UrAmerica through this MOU as we seek to further extend NANO Nuclear's international footprint," said Jay Yu, Founder and Chairman of NANO Nuclear. "By collaborating with UrAmerica, we aim to position Argentina as a regional center for nuclear technology and a reliable supply-chain partner for the United States, strengthening the country's existing infrastructure while advancing our shared goals."

"Argentina holds substantial deposits of strategic metals, like uranium, that could be a strategic supplier to us in the future," said James Walker, Chief Executive Officer of NANO Nuclear. "The timing is also favorable, as the Argentine government is actively looking to reform its nuclear sector to attract international investment. We look forward to advancing our discussions and exploring future opportunities in South America."

"This Memorandum of Understanding with NANO Nuclear marks a pivotal step forward in unlocking the vast potential of Argentina's uranium resources, aligning perfectly with UrAmerica's mission to drive sustainable and secure critical mineral supply chains," said Omar Adra, Executive Director & CEO of UrAmerica Ltd. and President of UrAmerica Argentina S.A. "Our extensive licenses package in the San Jorge Basin holds world-class uranium deposits, and through this collaboration, we aim to not only meet the growing global demand for nuclear fuel but also position Argentina as a key strategic partner for the United States in energy security. By leveraging UrAmerica's expertise in mineral exploration and NANO Nuclear's advanced nuclear technology and expertise, we are hopeful that this collaboration will catalyze investments in mining, milling, and fuel cycle development, delivering long-term economic benefits for Argentina while supporting the U.S. in diversifying its nuclear supply chain away from geopolitical risks."
