Arbor Metals Commences Phase 1 Drilling at Jarnet Lithium Project

Vancouver, Canada — March 9, 2026 — Leads & Copy — Arbor Metals Corp. has commenced its Phase 1 2026 diamond drilling program at its wholly owned Jarnet Lithium Project, located in the Eeyou Istchee James Bay region of Quebec.

The program is designed to follow up on encouraging lithium mineralization identified during the Company’s 2025 drill programs, which returned several notable lithium-bearing pegmatite intercepts. The Jarnet Lithium Project is adjacent to Patriot Battery Metals’ Shaakichiuwaanaan Property (formerly the Corvette Project).

Highlights from the 2025 Drill Program include:

JAR25-014 (Jarnet 2 – Prince Zone) intersected 1.56 metres grading 5,781 ppm Li (~0.57% Li) at 54.7 metres depth.

JAR25-015 (Jarnet 2) intersected 1.5 metres grading 2,224 ppm Li (~0.22% Li) at 212.06 metres depth.

On the Corvette claim blocks, holes JAR25-029, JAR25-030, and JAR25-031 intersected anomalous lithium values within a series of parallel pegmatite dykes located along greenstone–peridotite contacts.

The five-week Phase 1 program will consist of approximately 2,200 metres of diamond drilling across eight drill holes from four drill setups. Drilling will focus primarily on Jarnet 2, while also testing high-priority targets at Firebird, Corvette, and St. Pierre that were identified during earlier exploration campaigns.

Mark Ferguson, President of Arbor Metals Corp., said the company is excited to begin the 2026 drilling campaign at Jarnet following the encouraging lithium results obtained during its 2025 program. He added that the Phase 1 program is designed to expand on these results and further test the potential of multiple high-priority targets across the property. With drilling planned at Jarnet 2 and several additional prospective zones, Ferguson believes this program represents an important step in advancing the project and unlocking the broader lithium potential within the district.

Arbor is committed to conducting its exploration activities in a responsible and environmentally sustainable manner. The Company adheres to strict environmental standards and best practices, including minimizing ground disturbance and ensuring proper site reclamation following exploration activities. Arbor also places strong emphasis on collaborating with local communities, Indigenous Nations, and regional stakeholders in the Eeyou Istchee James Bay region, maintaining open communication and supporting responsible resource development that benefits all parties involved.

Arbor Metals Corp. is a mining exploration company focused on developing high-value, geographically significant mineral projects worldwide. 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.
