Vancouver, Canada – October 27th, 2025 – Arbor Metals Corp. (“Arbor” or the “Company”) (TSXV: ABR, FWB: 432) is pleased to announce that, after several months of negotiations, it has reached an agreement, with an arms-length party, to exchange its St. Pierre claim block in the Jarnet camp for the Ernest Rare Earth Elements (REE) Project. This exchange represents a strategic opportunity for Arbor and its shareholders to expand the Company’s resource portfolio into a complementary asset class where its technical expertise can potentially generate significant value.
The Ernest REE Project consists of 34 claims covering approximately 1,844 hectares in the Manicouagan region of Québec, located 20 km southwest of the René Levasseur (Manicouagan) crater. The project benefits from excellent access, situated just off Highway 389, approximately 200 km north of Baie- Cômeau. REE mineralization at Ernest was first noted in 2011 through a regional study conducted by Géologie Québec (Moukhsil et al.), which returned a select sample grading 5,539 ppm (0.55 % TREE), including 2,605 ppm Cerium, 1,466 ppm Lanthanum, 965 ppm Neodymium, and 274 ppm Praseodymium. Concurrent anomalous thorium (543 ppm) led to a 48.6 km ground radiometric survey in 2023, identifying ten highly anomalous radiometric zones. That same year, a property-wide drone magnetic survey totaling 425 km at 30 m line spacing was completed, further refining the geological understanding of the Project.
Rare earth elements are increasingly critical to the clean-energy transition and modern technologies, including electric vehicles, wind turbines, and advanced electronics. As stated by the International Energy Agency, “Demand for rare earth elements … grows threefold in the STEPS and more than sevenfold in the SDS by 2040” (“The Role of Critical Minerals in Clean Energy Transitions,” International Energy Agency, 2023). Additionally, the Council on Foreign Relations notes, “Critical minerals play an essential role in security and technological competitiveness, but the United States relies heavily on imports from China and other foreign sources” (“The U.S. Critical Minerals Dilemma: What to Know,” Council on Foreign Relations, 2023).
Arbor’s decision to exchange the St. Pierre claims—where the Company had previously identified lithium mineralization—is based on two key strategic considerations. First, the Company recognizes the growing importance of rare earth elements to secure domestic supply chains in North America. Second, the Jarnet Lithium Project’s overall scale has increased substantially, limiting Arbor’s ability to fully explore the St. Pierre claims while advancing other priority targets. The exchange allows the Company to maintain focus on its core Jarnet lithium holdings while adding a high-potential REE project to its asset base.
Mark Ferguson, President and CEO of Arbor, commented:
“The acquisition of the Ernest REE Project represents an important milestone for Arbor. We believe rare earths will play an increasingly vital role in the clean-energy economy, and this project positions us to participate in that growth from a strong, technical foundation. At the same time, we remain confident in the potential of the St. Pierre claims and look forward to seeing their development continue under new ownership. Our goal remains to collaborate with industry partners to help establish the Corvetie Lake region as a world-class critical-minerals district.”
Closing is expected to occur in the next few days, and Arbor will have ownership of the Ernest REE Project effective from August 15, 2025. No consideration is payable by the Company in connection with the acquisition of the Ernest REE Project, aside from the existing St. Pierre claim block. The Ernest REE Project is a subject to a two percent royalty obligation on commercial production.
Arbor will begin a comprehensive review of the Ernest REE Project’s existing datasets and will design a targeted exploration program aimed at defining high-priority drill targets. The Company expects to commence field activities in the near term, pending permit and logistical preparations. The Company maintains its commitment to responsible exploration, adhering to industry-leading environmental standards.Arbor conducts its operations in close consultation with local indigenous groups and community stakeholders to ensure that exploration activities are aligned with environmental stewardship, cultural respect, and long-term regional benefit.

About Arbor Metals Corp.
Arbor Metals Corp. 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, 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.
