ARBOR METALS IDENTIFIES LITHIUM ANOMALIES FROM PHASE 1 DRILLING AT JARNET LITHIUM PROJECT

Arbor Metals Corp. has released inaugural assay results on its wholly owned Jarnet lithium project located adjacent to Patriot Battery Metals' Shaakichiuwaanaan property (formerly known as the Corvette project), located in the Eeyou Istchee James Bay region of Quebec.

The phase 1 program, which consisted of 10 holes (1,913 metres), was designed to test large-scale pegmatite dike swarms identified in the 2023 and 2024 field programs, which included ground geophysics, surface sampling and systematic soil sampling. Lithium anomalies in the range of 100 to 310 parts per million were observed in 179 core samples and over 657 ppm in 27 per cent of the samples. Pegmatite dikes were mapped over widths ranging from one metre to 15 m, and were of varied and distinct compositions, which is suggestive of multiple phase events. Furthermore, the wide and consistent dissemination of the lithium values, which consistently increased at depth, may be indicative of an enrichment envelope.

Drilling focused on swarms of granitic pegmatite dikes hosted in varied lithologies: amphibolite, monzonite, granodiorite and sediments. Hole JAR-24-001 was drilled following an east-west direction to crosscut at right angle a quartz vein system hosting molybdenite. Holes JAR-24-006 and JAR-24-007 were drilled following a north-south direction, approximately one kilometre east of JAR-24-001 and 300 m to 500 m south from surface sampling. JAR-24-005 was drilled close to eastern the end of an outcrop following a north-west direction about 500 metres from holes JAR-24-006 and 007. Over all, the different targets covered an area of about 1.5 kilometres of strike length.

Results of the inaugural drill program support the company's hypothesis that the Jarnet 2 claims block hosts a kilometric-wide corridor of pegmatite dike swarms. While lithium values and observations have not as yet proved the presence of high-grade spodumene-bearing pegmatites, the broadly distributed lithium anomalies may indicate the presence of a fertile local environment for hosting a spodumene-bearing dike swarm.

Phase 1 drilling was performed by Forage et Construction Muskw, a joint venture between Forage Fusion Drilling and the Cree community, represented by Saskounan. Muskw, based in Chisasibi, Que., is co-owned and predominantly operated by local and indigenous stakeholders. Muskw's involvement exemplifies the success of local and indigenous ownership, and reinforces Arbor's commitment to community engagement and economic development in the regions where it operates. Arbor Metals extends its sincere gratitude to Muskw for its expertise, professionalism and dedication to the project.

Mark Ferguson, president and chief executive officer of Arbor, commenting: "The positive markers from our phase 1 drilling program have given us a solid foundation to build upon as we continue to explore the lithium potential at Jarnet. We are confident our upcoming program will provide additional critical information to help define the next steps for the project. We are eager to expand our efforts to include the high-priority target areas on the Firebird, Corvette and St. Pierre claims."

Arbor is committed to conducting all of its exploration activities with a strong focus on environmental stewardship. The company adheres to industry-leading environmental guidelines and strives to minimize its environmental footprint. Furthermore, Arbor continues to work collaboratively with local communities and other stakeholders to ensure its activities are aligned with the needs and concerns of the communities in which it operates.

About Arbor Metals Corp.

Arbor 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 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.

We seek Safe Harbor.
