ARBOR METALS IDENTIFIES THREE ZONES OF LITHIUM ENRICHMENT AT KEMLEE LAKE PROJECT ONTARIO, CANADA

Arbor Metals Corp. has completed 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 which utilized pre-existing trails to prospect the property, collecting 27 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-metre intervals. Bark sampling was previously proved 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 in Thunder Bay, Ont. Analysis of the surface sampling identified three distinctive target zones (LZ-1, LZ-2 and 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 parts per billion -- 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 chief executive officer 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.

About Arbor Metals Corp.

Arbor Metals is a mining exploration company focused on developing high-value, geographically significant mineral projects worldwide. Arbor is paving the way for advanced mineral exploration as it oversees world-class mining projects. The company is confident that combining quality projects with proven strategies and a dedicated team will yield exceptional outcomes.

The Jarnet, Corvette Lake and St. Pierre lithium projects, located in the James Bay region of Quebec, comprise 83 map-designated claims, covering an area of approximately 5,606 hectares. The projects are contiguous to the Corvette-FCI property, where diamond drilling has confirmed significant lithium mineralization, representing one of the highest-profile lithium exploration projects in the sector.

The Kemlee Lake lithium project is strategically located three kilometres east of Rock Tech Lithium Inc.'s Aumacho claim blocks and 12 kilometres south of the Georgia Lake project. The project shares many geological similarities with the prolific Georgia Lake deposit, including bedrock geology and the presence of massive intrusive dikes. The primary target at the project will be spodumene-bearing pegmatites hosted in metasediments.
