Brisbane, Queensland, Australia–(Newsfile Corp. – September 3, 2024) – Graphene Manufacturing Group Limited (TSXV: GMG) ("GMG" or the "Company") is pleased to announce this business update on its recently commissioned Modular Graphene Production Plant at Richlands, Australia.

The newly commissioned Graphene Production Plant as seen in Figure 1 has been operating and producing Graphene since its commissioning date in December 2023.

The performance of the production unit has exceeded the Company's expectations in both graphene production rate and graphene quality. The Company continues to perform minor optimisations with this new production plant which have both increased production yield and quality of the graphene.

The Company has also authorised a total of AU$250k of capital expenditure for new equipment for quality assurance and quality control purposes of the Company's graphene for its Graphene Aluminium Ion Battery and its liquid graphene products, THERMAL-XR® and G® Lubricant. The equipment being procured by the Company includes: a Raman Spectrometer and a Particle Size Analyzer amongst others. These are sophisticated analytical and characterisation laboratory equipment which will be operated by GMG scientists and technicians. To date the Company has been fortunate to work with various Universities to obtain this analysis. Once the equipment is procured, delivered, commissioned and operational the Company will largely be self-sufficient on testing of its nano materials.

GMG's Managing Director and CEO, Craig Nicol, commented: "We are very excited to see the new modular plant exceed expectations in terms of graphene production and quality. The expansion of our graphene characterisation equipment will also reduce learning loop times for optimisation projects where we no longer have to wait for University equipment access. The graphene production system uses GMG's self developed innovative plasma technology which creates the high quality graphene GMG's end products need to deliver their notable benefits."

GMG's Chairman and Director, Jack Perkowski, commented: "It is great to see the Company's production technology maturing to this point as this is GMG's fundamental core competency. Ongoing graphene production and characterisation developments will only support the Company's ability to develop and provide its useful liquid graphene products and Graphene Aluminium Ion Battery."

About GMG www.graphenemg.com

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 G+AI Batteries.

This information and these statements, referred to herein as "forward‐looking statements", are not historical facts, are made as of the date of this news release and include without limitation: statements relating to the type of equipment being procured by the Company and the operators of such equipment; and the expected benefits of the analytical and characterisation laboratory equipment.

Such forward-looking statements are based on a number of assumptions of management, including, without limitation: assumptions relating to the type of equipment that will be procured by the Company; that the equipment will be operated by the Company's scientists and technicians; that once the equipment is procured the Company will be able to perform its own testing of nano materials; that the expansion of GMG's characterisation equipment will reduce learning loop times for optimisation projects as the Company will no longer have to wait for University equipment access; and that ongoing graphene production and characterisation developments will support the Company's ability to develop and provide its products.

Additionally, forward-looking information involves a variety of known and unknown risks, uncertainties and other factors which may cause the actual plans, intentions, activities, results, performance or achievements of GMG to be materially different from any future plans, intentions, activities, results, performance or achievements expressed or implied by such forward-looking statements. Such risks include, without limitation: that the Company will be unable to procure the expected equipment; that the Company's scientists and technicians will be unable to operate the new equipment; that even if the expected equipment is procured, that Company will not become self-sufficient in testing its own nano materials; that the expansion of the Company's graphene characterisation equipment will not reduce learning loop times for optimisation projects; that ongoing graphene production and characterisation developments will not support the Company's ability to develop and provide its products; risks relating to the extent and duration of the conflict in Eastern Europe and its impact on global markets; the volatility of global capital markets; political instability; the failure of the Company to obtain regulatory approvals, attract and retain skilled personnel; unexpected development and production challenges; unanticipated costs; and the risk factors set out under the heading "Risk Factors" in the Company's annual information form dated October 12, 2023 available for review on the Company's profile at www.sedarplus.ca.

Although management of the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements or forward-looking information, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements.
