BOOTS-ON-THE-GROUND WORK PROGRAM COMMENCES AT THE JUPITER LITHIUM PROJECT IN JAMES BAY, QUEBEC

Green Battery Minerals Inc. has commenced a work program at the highly prospective Jupiter lithium property in James Bay, following the successful acquisition of the project in early 2023 (see May 4, 2023, news release) where numerous pegmatite observations have been reported.

Tom Yingling, president and chief executive officer of Green Battery Minerals, commented: "We are commencing aggressive 2023 exploration on our Jupiter lithium property with a ground-truthing, 'Boots-on-the-Ground' program. Our project, located in the resource prolific James Bay area, benefits from up to 33 pegmatite descriptions that have been documented. We are now advancing this historical information and are targeting the identification of potential lithium-bearing minerals. Jupiter lithium property is surrounded by some of the biggest lithium projects in North America, including the James Bay and Rose deposits, as well as Patriot Battery Metals Inc.'s (TSX: PMET) project. The findings at these projects have created significant shareholder value for many companies working in the area. Based on these nearby discoveries and the presence of a large number of documented pegmatite on the property, we believe we are well positioned to drive additional value for our shareholders too, contingent on the results of this program."

Helicopter-assisted rock sampling program

The Green Battery team is currently evaluating the 33 pegmatite locations at the property; with a view to reviewing each during the work program that is to commence this week at the primary target areas.

The experienced team at Axiom Group have been secured to manage the helicopter-assisted rock sampling program at the Jupiter property. Two teams are currently mobilizing to the KM381 base near the property to commence the field program.

Teams will be aggressively covering the ground where the clusters of pegmatites have been identified already, in the field, by government geologists. Where favourable outcrops are encountered, Axiom Group will systematically map and sample the outcrops and will submit the samples collected to SRC Laboratories for comprehensive analysis following the field program.

About the Jupiter property

The Jupiter property was optioned to explore for lithium (LCT) pegmatites, and rare earth elements (REE). The property is an early stage exploration opportunity which comprises a total of 122 Quebec mineral exploration claims which amount to a total of 6,406 hectares. Up to 33 pegmatite occurrences have been identified by government mapping completed over the property. Rock samples collected adjacent to the property returned up to 315 ppm (parts per million) lithium. These claims are strategically located within the James Bay lithium prospectivity area within which are the Nemaska lithium, James Bay lithium and Rose critical elements deposits. The Jupiter property fulfills the company's goal of providing additional battery elements that go into lithium-ion batteries.

Property highlights

• The Jupiter property is located within the La Grande geological subprovince, near the boundary with the Opinaca subprovince within a favourable host rock comprising "typically porphyritic and magnetic tonalite; with minor injections of pink pegmatite."
• Up to 33 pegmatite occurrences have been identified by government mapping completed over the property. Rock samples collected adjacent to the property returned up to 315 ppm lithium.
• The acquired claims are located over regionally elevated lake bottom sediment geochemical anomalism for lithium, with values up to 100 ppm along the down ice trend of the property.
• Float plane and helicopter accessible, approximately 175 km south of Radisson, and 25 km southwest of the Eleonore mine and Airstrip. The northern infrastructure corridor comprising Rte de la Baie-James provincial highway and three Power transmission lines is located approximately 35 to 50 km east of the property.

Green Battery metal critical minerals property portfolio:

• Berkwood graphite project -- Quebec -- graphite project;
• Jupiter -- Quebec -- lithium pegmatite (LCT) prospect;
• Stallion -- British Columbia -- copper porphyry, epithermal Au+Ag (gold plus silver) prospect;
• Boudrias -- Quebec -- nickel-copper (PGE) prospect.

About the Berkwood graphite project

The Berkwood graphite project is located within the jurisdiction of Quebec, in the Manicouagan regional county municipality, three hours driving time from the city of Baie-Comeau. Easy access is provided via a major secondary road and numerous tertiary and forest roads that traverse the property.

The Zone 1 deposit lies eight km southwest of Nouveau Monde's deposit which has a $3.5-billion NPV (net present value) on it. The company's Zone 1 deposit, and that of Nouveau Monde, share many similar geological characteristics, with the Zone 1 deposit being of exceptionally high grade and coarse flake size by global standards.

The current mineral resource at the Berkwood graphite project includes in-pit constrained resource totalling 1,755,300 tonnes of indicated resources at 17.00 per cent Cgr and 1,526,400 tonnes in inferred resources at 16.39 per cent Cgr.

The mineral resource estimates herein are described in the technical report entitled, National Instrument 43-101 technical report mineral resource estimate on the Lac Gueret south graphite property, Quebec, Canada. With an Effective date of June 30, 2019, by Edward Lyons, PGeo, Florent Baril, ing, and Claude Duplessis, ing.
