Vancouver, Canada – July 17th, 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, which was conducted by a six-person crew, involved the collection of valuable geological samples to advance the exploration efforts at this promising lithium property.

The prospecting work focused on utilizing preexisting trails across the property. The team obtained a total of twenty-seven rock samples from outcrops, which are expected to provide insights into the geological characteristics of the property. Additionally, the team collected 622 tree bark samples from black spruce trees, which were taken along traverse lines that mirrored the winter magnetometer survey lines, running east-west at 100-meter intervals. The tree bark sampling technique was previously proven successful during exploration at the Georgia Lake Lithium Project (Rock Tech Georgia Lake Inc.) in 2023.

Both the rock and bark samples were delivered to Activation Laboratories (“Act Labs”) in Thunder Bay, Ontario, where they were processed before being sent to Act Labs’ laboratory in Ancaster, Ontario, for preparation and analysis. The results of these analyses will be critical in further defining lithium-bearing zones and guiding future drilling programs.

“We are pleased to have completed this important prospecting program at the Kemlee Lake Lithium Project,” said Mark Ferguson, President and CEO of Arbor. “The collection of both rock and tree bark samples in key areas of the property represents a significant step forward in advancing our understanding of the project’s potential. We look forward to receiving the results and building on this information as we continue to move the project forward.”

Arbor is committed to conducting all of its exploration activities with a strong focus on environmental responsibility. The Company adheres to industry-leading environmental guidelines and practices to minimize its environmental footprint. Arbor continues to work closely with local communities and indigenous groups to ensure that its exploration efforts are conducted with respect to the environment and the needs of local stakeholders.

The Jarnet, Corvette 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 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 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 similarities 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 pegmatites hosted in metasediments.
