Green Battery Minerals Strengthen ESG Credentials Through Successful Air Separation Test of its Graphite

Solventless Process - Vancouver, British Columbia, | May 16th, 2023 - Green Battery Minerals Inc. (the "Company") (TSXV:GEM) (FSE:BK2P) (WKN:A2QENP) (OTC:GBMIF) is pleased to announce it has completed a new purification test with Volt Carbon Technologies ("VCT") (TSXV: VCT).

One of our goals is to continue to make graphene from our large to jumbo flake graphite. This process brings us one step closer, and significantly greener.

Current purification of battery-grade anode material requires large quantities of reagents such as sodium hydroxide and hydrofluoric acid, as well as significant amounts of water, which consequently will be contaminated and needs to be treated before reentering the environment. The new process utilizes air as its separation medium, thereby omitting the use of solvents and does not produce contaminated liquid waste.

The preliminary results of the graphite ore processing test using VCT's dry separation Technologies yielded graphite grades to 93%, based on Thermogravimetric Analysis provided by VCT's laboratory in Guelph, Ontario.

High-Grade Large and Jumbo Flake Graphite Produced

The test was run utilizing 5 kg of crushed feedstock sample from the Company's Berkwood property. The final results yielded 146 grams of graphite flake per kilogram of crushed feedstock, reflecting a of 14.6% yield of graphite flakes per kg of feedstock.

Importantly, the resulting flake size distribution (see Figure 1 below) showed that the majority of the Berkwood graphite produces large and jumbo sized flakes, ideal for the production of anode material for lithium-ion batteries ("LiBs"). Large and jumbo flakes command among the highest graphite prices on the market of up to $2,500 per ton.

The Graphite provided by VCT was subsequently sent to a third-party lab - Base Metallurgist Laboratories Ltd in Kamloops, for independent testing. The results, tabulated below in Figure 3, verified that the VCT-processed sample tested yielded a graphite content of 91.55%, with total carbon showing at 97%. These results validate the effectiveness of VCT's current process, which is currently being scaled up.

Management Commentary

Thomas Yingling, President and CEO of Green Battery Minerals, commented, "We are very excited with the results of the VCT air separation test for multiple reasons. Firstly, the process eliminates a significant amount of waste traditionally associated with the purification of graphite due to its solventless and reagentless nature. This is a major step forward and further strengthens our green credentials. In speaking to the automobile industry, it is obvious that ESG considerations play a major role in purchase decisions. While graphite is in short supply, this advance positions us well to secure market share should we reach full production. Secondly, the new process does not hurt flake size distribution. As our property benefits from significant concentrations of large and jumbo-sized flakes, this outcome ensures we can command among the highest prices for our graphite. This potentially disruptive technology could greatly benefit Green Battery Minerals as we plan to move towards commercial development."

Next Steps

The Company and VCT intend to utilize a 5,000 kg Graphitic sample to produce commercial scale samples for testing by the automotive industry and other potential customers. This next step will also be used to more accurately determine costing, which will be significantly lower than currently utilized processes.

Mr. Yingling added, "In addition to the process's high-quality output and green credential, we believe that by utilizing VCT's dry separation technology, we will have a material economic advantage over traditionally processed graphite due to significantly lower CapEx and operating costs. This should further strengthen our competitive position, and we believe this will help position us as a major supply partner to the EV and other industries."
