Operations Update

GMG is concentrated on providing its Gen 2.0 Graphene Production Project (the “Gen 2.0 Project”by end of June 2026– which is anticipated to produce a minimum of 10 tonnes per year of graphene at its head office in Richlands, Queensland, Australia.

When the Gen 2.0 Project is commissioned and operating. GMG prepares to duplicate and develop other production plants worldwide to make it possible for scaled production for possible sales, diversify and lower production dangers, and in the end, lower running expenses by finding the plant in nations with lower operating expense, consisting of low expense gas– among GMG’s essential production input expenses.

Presently, GMG is preparing 3 possible growth jobs– 2 in North America (possibly one in United States and one in Canada) in addition to a growth production job in Australia. GMG proposes to develop these jobs and broaden production in line with sales for all of its items.

The growth program for GMG consists of the following 5 production plants:

1. Graphene Production (from gas)
2. Finish Blend Plant (for the graphene finish THERMAL-XR ® )
3. Lube Blend Plant (for the graphene lube additive G ® LUBRICANT)
4. Graphene Slurry Plant (for the SUPA G Lithium-Ion Battery Additive)

GMG is an Australian based clean-technology business which establishes, makes and offers energy conserving and energy storage options, allowed by graphene made by means of in home production procedure. GMG utilizes its own exclusive production procedure to disintegrate gas (i.e. methane )into its natural components, carbon (as graphene), hydrogen and some recurring hydrocarbon gases. This procedure produces high quality, low expense, scalable,’tuneable’and low/no pollutant graphene appropriate for usage in clean-technology and other applications.

The Company’s present focus is to de-risk and establish business scale-up abilities, and safe market applications. In the energy cost savings section, GMG has actually at first concentrated on graphene boosted heating, ventilation and a/c (“HVAC-R”finishing(or energy-saving finishing)which is now being marketed into other applications consisting of electronic heat sinks, commercial procedure plants and information centres. Another item GMG has actually established is the graphene lube additive concentrated on conserving liquid fuels at first for diesel motor.

In the energy storage section, GMG and the University of Queensland are working collaboratively with financial backing from the Australian Government to advance R&D and commercialization of graphene aluminium-ion batteries(“G+AI Batteries”. GMG has actually likewise established a graphene additive slurry that is focused on enhancing the efficiency of lithium-ion batteries.

GMG’s 4 crucial service goals are:

1. Produce Graphene and improve/scale cell production procedures
2. Build Revenue from Energy Savings Products
3. Establish Next-Generation Battery
4. Establish Supply Chain, Partners & Project Execution Capability
