NANO ONE PRE-QUALIFIES LITHIUM FROM RIO TINTO FOR LFP CATHODE PRODUCTION AND PROVIDES STRATEGIC COLLABORATION UPDATE

Nano One Materials Corp. has provided an update on its continuing collaboration with Rio Tinto specific to the prequalification of high-volume battery-grade raw material inputs for Nano One's One-Pot lithium-iron-phosphate (LFP) cathode active material (CAM) production process.

"We are adding value to our technology and licence offering by prequalifying feedstock that is critical to the production of LFP. This will assist our prospective licensee partners manage supply chain risks and accelerate time to market for future One-Pot commercial plants. There continues to be a need for secure, diversified and economically localized LFP cathode active material supply chains. We believe that our One-Pot processing technology can be bundled with prequalified input feedstocks from premier producers such as Rio Tinto, to help partners, licensees and customers achieve their objectives," stated Alex Holmes, chief operating officer of Nano One.

Rio Tinto is a leading global mining group and a major lithium producer, with one of the world's largest lithium resource bases. With strategically located lithium assets across key regions, Rio Tinto intends to grow the capacity of its Tier 1 lithium assets to over 200,000 tonnes per year of lithium carbonate equivalent (LCE) by 2028.

Collaboration and prequalification of Rio Tinto's critical minerals and raw materials inputs include:

• Lithium carbonate from Rio Tinto's Fenix site at the Salar del Hombre Muerto in Catamarca, Argentina, qualified at C-sample (tonne scale), with 10 tonnes purchased for pilot and customer validation work;
• Lithium carbonate from Rio Tinto's Olaroz site in Jujuy, Argentina, qualified at A-sample (kilogram scale) for diversified sourcing strategy, progressing to C-sample qualification;
• Precommercial lithium carbonate samples from Rio Tinto's Rincon project in Argentina have been evaluated for future supply.

Nano One conducts qualification of battery-grade raw materials through a rigorous, staged testing protocol at increasing scales from A-sample (kilograms) through C-sample (one to 10 tonnes) prior to D-samples in a commercial plant setting. By prequalifying raw material inputs, Nano One aims to accelerate customer acceptance of its LFP product and LFP CAM licensing packages. This will also derisk supply chains for prospective licensees and fast-track A- through C-sample qualification programs by as much as one year. The strategic collaboration between the parties aligns with Nano One's technology licensing and growth strategy while supporting regional LFP supply chain development opportunities.

About Nano One Materials Corp.

Nano One is a technology company changing how the world makes cathode active materials for lithium-ion batteries. Applications include stationary energy storage systems (ESS), portable electronics and electric vehicles (EVs). The company's patented One-Pot process reduces costs, is easier to permit, and lowers energy intensity, environmental footprint and reliance on problematic supply chains. The company is helping to drive energy security, supply chain resilience, industrial competitiveness and increased performance through process innovation. Scalability is proven and being demonstrated at Nano One's LFP (lithium-iron-phosphate) pilot production plant in Quebec -- leveraging the only facility and expertise of its kind outside of Asia. Strategic collaborations and partnerships with international companies such as Sumitomo Metal Mining, Rio Tinto and Worley are supporting a design-one-build-many licensing growth strategy -- delivering cost-competitive, easier-to-permit and faster-to-market battery materials production solutions around the world. Nano One has received funding from the government of Canada, the government of the United States, the government of Quebec and the government of British Columbia.
