Arbor Metals Identifies Three Zones of Lithium Enrichment at Kemlee Lake Project Ontario, Canadat

NEWS RELEASE

ARBOR METALS IDENTIFIES THREE ZONES OF LITHIUM ENRICHMENT

AT KEMLEE LAKE PROJECT ONTARIO, CANADAT

Vancouver, Canada – August 29th, 2025 – Arbor Metals Corp. (“Arbor” or the “Company”) (TSXV: ABR,

FWB: 432) is pleased to announce the successful completion of its 2025 prospecting program at its wholly

owned Kemlee Lake Lithium Project, located on the eastern shore of Lake Nipigon, Ontario.

The program was conducted by a six-person crew who utilized preexisting trails to prospect the property,

collecting twenty-seven rock samples from outcrop. In addition, 622 bark samples from Black Spruce were

collected along traverse lines that mirrored the winter magnetometer survey lines, running east–west at

100-meter intervals. Bark sampling has previously been proven as an effective exploration technique at

the Georgia Lake Lithium Project (Rock Tech Georgia Lake Inc.) in 2023.

All rock and tree bark samples were analyzed by Activation Laboratories (“Act Labs”) in Thunder Bay,

Ontario. Analysis of the surface sampling identified three distinctive target zones (LZ-1, LZ-2, LZ-3)

intersecting the primary north–south trending pegmatite body. The target zones extend east–west and

showed anomalous lithium enrichment, with the highest values in the clusters grading up to 360 ppb—

many magnitudes above background levels. The Company is pleased with these results, which indicate

well-defined zones of anomalous lithium enrichment. The exploration team is continuing efforts to refine

these results, with the goal of defining priority diamond drilling targets for future programs.

Mark Ferguson, President and CEO of Arbor, commented: “The 2025 Kemlee Lake prospecting program

has provided us with highly encouraging results. Identifying three well-defined lithium-enriched target

zones is a significant step forward in advancing our understanding of the project. These results provide a

strong foundation for selecting high-priority drilling targets as we continue to explore this promising

property.”

Arbor is committed to conducting all exploration activities with a strong focus on environmental

stewardship. The Company adheres to industry-leading environmental guidelines and works diligently to

minimize its environmental footprint throughout the exploration process. In addition, Arbor continues to

consult and collaborate closely with local stakeholders and Indigenous groups to ensure that its activities

are conducted responsibly and in alignment with community priorities and values.

The Jarnet, Corvefte Lake and St. Pierre lithium projects, located in the James Bay region of Quebec,

comprises 83 map-designated claims, covering an area of approximately 5,606 hectares. The projects are

configuous to the Corvefte-FCI property, where diamond drilling has confirmed significant lithium

mineralizafion represenfing one of the highest-profile lithium explorafion projects in the sector.

The Kemlee Lake Lithium project is strategically located three kilometers east of Rock Tech Lithium Inc.'s

Aumacho claim blocks and twelve kilometers south of the Georgia Lake Project. The Project shares many

geological similarifies with the prolific Georgia Lake deposit, including bedrock geology and the presence

of massive intrusive dykes. The primary target at the Project will be spodumene- bearing pegmafites

hosted in metasediments.
