ARBOR METALS COMMENCES PHASE 1 2026 DRILL PROGRAM AT JARNET LITHIUM PROJECT

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, adjacent to Patriot Battery Metals' Shaakichiuwaanaan property (formerly the Corvette project) (1).

The phase 1 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.

Highlights from the 2025 drill program (2):

• JAR25-014 (Jarnet 2 -- Prince zone) intersected 1.56 metres grading 5,781 parts per million (ppm) lithium (Li) (approximately 0.57 per cent Li) at a depth of 54.7 metres.
• JAR25-015 (Jarnet 2) intersected 1.5 metres grading 2,224 ppm Li (approximately 0.22 per cent Li) at a depth of 212.06 metres.
• On the Corvette claim blocks, holes JAR25-029, JAR25-030 and JAR25-031 intersected anomalous lithium values within a series of parallel pegmatite dikes 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 set-ups. 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.

Management commentary

"We are excited to begin the 2026 drilling campaign at Jarnet following the encouraging lithium results obtained during our 2025 program," said Mark Ferguson, president of Arbor Metals.

"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, we believe this program represents an important step in advancing the project and unlocking the broader lithium potential within the district."

Environmental stewardship and community engagement

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.

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.
