Arbor Metals Commences Phase 1 2026 Drill Program At Jarnet Lithium Project (TheNewswire) Vancouver, Canada – March 9th, 2026 – TheNewswire – Arbor Metals Corp. (“Arbor” or the “Company”) (TSXV: ABR, FWB: 432) is pleased to announce the commencement of 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 Program2 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. 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 Corp. “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 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.
