NEWS RELEASE

Grid Battery Announces the Completion of the First Phase of its 2025 Fall

Exploration Program for its British Columbia Gold-Copper Property

Coquitlam, BC – September 17, 2025- Grid Battery Metals Inc. (the “Company” or “Grid”) (TSXV:

CELL, OTCQB: EVKRF FRA: NMK2) is pleased to announce that the first phase of the fall exploration

program has been completed by our Canadian contract geological team, Hardline Exploration

www.hardlineexploration.com. Founded in 2014, Hardline, is a leading geological consulting firm

operating in western Canada. Hardline works directly with local contractors and First Nations to

ensure their projects receives the most efficient & dedicated exploration services available. They

specialize in executing complex exploration programs to generate new discoveries and have a proven

track record of successful projects incorporating highly skilled geologists and team members.

Please refer to the Technical Report for Grid BC Copper-Gold Project, dated January 24, 2025

prepared by Jeremy Hanson, P.Geo. (filed on SEDAR+ and our website).

2025 Exploration Program

Mr. Tim Fernback, President & CEO comments “We’re excited to have previously acquired

approximately 275 km 2 of tenures in such a favourable mining region within British Columbia,

Canada. This area of the Province has already generated several promising projects, and our land

package is strategically situated to exploit the high gold-copper values of the region. NorthWest

Copper Corp. ( TSXV: NWST ) on the nearby Kwanika project intercepted 400 metres of 1.01 %

Copper equivalent (News Release: January 16, 2023 Northwest Copper Corp ). Nearby the Mount

Milligan open pit gold-copper mine operated by Centerra Gold ( TSX: GX, NYSE:CGAU ) recently

announced its pre-feasibility study that extended the life of its open pit ming by about 10 years. The

area has proven itself to be a great place to look for both gold and copper. British Columbia is well

known to be a safe and mining-friendly jurisdiction with reasonable government permitting

processes and great mining infrastructure.”

Mr. Fernback continues “We have recently concluded our initial exploration program on two of the

five claim blocks recently acquired as part of our Fall Exploration Phase 1. Here a large assaying,

trenching, sampling and geophysics program was strategically situated within the Jupiter and

Starlight claim blocks. We expect to have these assay results by the end of the fall with next

exploration steps identified on the various claim blocks shortly thereafter.”

“The exploration program follows up on previous work conducted by others in 2023 and includes

geochemistry across various untested magnetic features on Starlight and Jupiter claims. The areas

on these two large claim blocks include detailed soil sampling, mapping and prospecting on eight

targeted areas for both gold and copper initially identified by our geological team.”

About the Gold-Copper Property

The Company acquired a 100% interest in 17 mineral claims comprising 27,525 hectares

(approximately 275 km2) located in North Central British Columbia. The region is host to numerous

operating mines, good infrastructure including experienced exploration and supporting services.

Prominent among early discoveries in the Omineca region include the nearby Lustdust/Stardust

Copper – Gold deposit; the Kwanika Copper - Gold deposit and the Lorraine Copper deposit (all of

which are owned by (NorthWest Copper Corp. (TSXV: NWST)).

The Company’s claims are also located between Centerra Gold Inc.’s ( TSX: CG, NYSE: CGAU )

prominent Copper/Gold assets, the Kemess North project and the operating Mount Milligan mine,

which has produced over 1.8 million ounces of gold and 742 million pounds of copper (Technical

Report on the Mount Milligan Mine, November 7, 2022, Borntrager. B, et al.).

B.C. Minfile assessment report data indicates that most of the area covered by the Copper Property

was at one time or another covered by staking during surges of exploration in B.C. dating from the

1940’s to present day. Largely the claims appear to have been minimally explored with little follow-

up. However, some work was recorded on several claims with results for stream sediment sampling

showing anomalous to highly anomalous results for gold in a few areas. These areas were

recommended for detailed follow-up, however due to a downturn no further work was recorded

The Omineca Group claim areas are within the northern Quesnel Trough underlain by Cache Creek

Terrane and lies close to the Pinchi Fault. The Quesnel Trough hosts numerous porphyry copper-

gold deposits. The Pinchi Fault can be traced for 600 km through north-central B.C and separates

Cache Creek rocks from the Jurassic Hogem Batholith and Triassic-Jurassic Takla rocks to the west.

Rocks have a north-northwest strike trend typical of the entire Intermontane Belt in which the Cache

Creek Terrane lies (Gabrielse and Yorath, 1992). A wide range of Jurassic to Tertiary intrusions cuts

the Cache Creek Assemblage and many of these are emplaced along the prominent NW-trending

structures and stratigraphic breaks. Numerous mercury occurrences are present along the length of

4

the Pinchi fault (Albino, 1987) and a few gold and base metal occurrences are present near the Pinchi

fault including the Lustdust, Lorraine, Indata and Axelgold properties. There are at least two alkalic

gold-copper Porphyry systems in the immediate Lustdust (now known as Stardust) area: J49 and

Axel Properties (Schiarrizza, 2000).

In other news, the Company has announced that it has formally dropped the Volt Canyon Lithium

property from its Nevada lithium exploration portfolio. The Company had a 100% interest in 80

placer claims covering approximately 635 hectares of alluvial sediments and clays located 122 km

northeast of Tonopah, Nevada, but accessing the property proved difficult and initial sampling results

were considered average and not exceptional by our geological team.

About Grid Battery Metals Inc. www.gridbatterymetals.com.

Grid Battery Metals Inc. is a Canadian based exploration company whose primary listing is on the

TSX Venture Exchange. The Company’s maintains a focus on exploration for high value battery

metals required for the electric vehicle (EV) market.

About Texas Springs Property

The Company owns a 100% interest in the Texas Spring Property which consists of mineral lode

claims located in Elko County, Nevada. The Property is in the Granite Range southeast of Jackpot,

Nevada, about 73 km north-northeast of Wells, Nevada. The target is a lithium clay deposit in

volcanic tuff and tuffaceous sediments of the Humbolt Formation. A Phase 1 exploration program

at the Texas Springs Property (Fall 2023) yielded average lithium grades of 2010 ppm, applying a

1,000 ppm cut-off, and up to 5,610 ppm Lithium.

The Texas Spring property adjoins the southern border of the Nevada North Lithium Project -

owned by Surge Battery Metals Inc. (“Surge”) (TSXV: NILI, OTC: NILIF) and comprised of 725

mineral claims. Surge's first round of drilling identified strongly mineralized lithium bearing clays.

The average lithium content within all near surface clay zones intersected in the 2022 drilling

program, applying a 1000 ppm cut-off, was 3254 ppm. (Press release March 29, 2023). More recent

results have shown higher grade lithium up to 8070 ppm on this property after initial drilling (Press

release September 12, 2023). Our exploration results are on-trend with these results.

About Clayton Valley Lithium Project

The Company owns a 100% interest in 113 lithium lode and placer claims covering over 930

hectares in Clayton Valley. Clayton Valley is a down-dropped closed basin formed by the Miocene

age Great Basin extension and is still active due to movement along the Walker Lane structural zone.

As a result, the basin has preserved multiple layers of lithium bearing volcanic ash, resulting from

multiple eruptive events over the past 6 million years including eruptions from the 700,000-year-

old Long Valley Caldera system and related events. These ash layers are thought to contribute to

the lithium brines extracted by Albemarle and are also likely involved in the formation of the

exposed lithium rich clay deposits on the east side of Clayton Valley.
