GMG Announces Battery Joint Development Agreement with Rio Tinto

Rio Tinto will seek to involve Original Equipment Manufacturers (OEM), including Heavy Mobile Equipment OEMs, to work with GMG and Rio Tinto to align the battery pack development with end use requirements.

Success could see performance enhancements for Rio Tinto, including faster charging and longer-life batteries for heavy mobile equipment and grid energy storage, as well as supporting Rio Tinto's decarbonisation ambitions.

GMG will retain ownership of the intellectual property of the GMG Graphene Aluminium Ion Battery Pouch Cell and Battery Pack. On successful completion of the joint project, Rio Tinto would have the right to procure and use the batteries in their operations.

Rio Tinto Chief Scientist, Nigel Steward, said, "We are excited to expand and deepen our partnership with GMG. We both share a vision of a low-carbon future and for Rio Tinto it's a crucial time to partner with companies like GMG to accelerate battery technology and innovation. We are looking forward to continuing our collaboration and leveraging our combined expertise and resources to develop a truly green battery that has the potential to improve the way we supply and store energy."

GMG's Managing Director and CEO, Craig Nicol, commented: "We are excited to be collaborating with Rio Tinto, one of the world's largest mining companies who are committed to leveraging leading technologies for efficient and low carbon operations. The collaboration with Rio Tinto on the applications of Graphene Aluminium-Ion batteries is a key step for GMG. Together, with the existing technical and supply chain partnerships already established, this is another important step towards GMG's goal to become a major global supplier of next generation batteries as we continue to de-risk the commercial scale up of this technology."

Guy Outen, GMG's Chair, commented: "I am very pleased to further deepen our partnership with Rio Tinto. I believe the opportunity to work closely with them given their capability and drive as a large potential customer to access leading new technologies will greatly assist the potential development of our next generation Graphene Aluminium-Ion batteries. More broadly, significant customer feedback to GMG has reinforced the opportunity of the pouch cell battery format and this JDA with Rio Tinto is another example. We'll now re-prioritise our energies to developing this form of battery which should further support progress towards our aim of a commercial, large scale, highly competitive battery."

About Rio Tinto

Rio Tinto is a leading global mining and materials company. Rio Tinto operates in 35 countries and produces iron ore, copper, aluminium, critical minerals and other materials needed for the global energy transition and for people, communities, and nations to thrive. They have been mining for almost 150 years and operate with knowledge built up across generations and continents. Rio Tinto's purpose is finding better ways to provide the materials the world needs - striving for innovation and continuous improvement to produce materials with low emissions and to the right environmental, social and governance standards.

About GMG

GMG is a clean-technology company which seeks to offer energy saving and energy storage solutions, enabled by graphene, including that manufactured in-house via a proprietary production process.

GMG has developed a proprietary production process to decompose natural gas (i.e. methane) into its elements, carbon (as graphene), hydrogen and some residual hydrocarbon gases. This process produces high quality, low cost, scalable, 'tuneable' and low/no contaminant graphene suitable for use in clean-technology and other applications. The Company's present focus is to de-risk and develop commercial scale-up capabilities, and secure market applications.

In the energy savings segment, GMG has focused on graphene enhanced heating, ventilation and air conditioning ("HVAC-R") coating (or energy-saving paint), lubricants and fluids. In the energy storage segment, GMG and the University of Queensland are working collaboratively with financial support from the Australian Government to progress R&D and commercialization of graphene aluminium-ion batteries ("G+AI Batteries").
