Arbor Metals Identifies Lithium Anomalies from Phase 1 Drilling at Jarnet Lithium Project

NEWS RELEASE

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

Vancouver, Canada – June 2, 2025 – Arbor Metals Corp. (“Arbor” or the “Company”) (TSXV: ABR, FWB:

432) is pleased to announce inaugural assay results on its wholly owned Jarnet Lithium Project located

adjacent to Patriot Baftery Metals’ Shaakichiuwaanaan Property (formerly known as the Corvefte 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

pegmafite dykes swarms idenfified in the 2023 and 2024 field programs, which included ground

geophysics, surface sampling and systemafic soil sampling. Lithium anomalies in the range of 100 to 310

ppm were observed in 179 core samples and over 657ppm in 27% of the samples. Pegmafite dykes were

mapped over widths ranging from 1m to 15m and were of varied and disfinct composifions, which is

suggesfive of mulfiple phase events. Furthermore, the wide and consistent disseminafion of the lithium

values, which consistently increased at depth, may be indicafive of an enrichment envelope.

Drilling focused on swarms of granific pegmafite dykes hosted in varied lithologies: amphibolite,

monzonite, granodiorite and sediments. Hole JAR-24-001 was drilled following an east-west direcfion to

crosscut at right angle a quartz vein system hosfing molybdenite. Holes JAR-24-006 and JAR-24-007 were

drilled following a north-south direcfion, ~ 1km east of JAR-24-001 and 300m to 500 metres south from

surface sampling. JAR-24-005 was drilled close to eastern the end of an outcrop following a north-west

direcfion about 500 metres from holes JAR-24-006 and 007. Overall, the different targets covered an area

of about 1.5km 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 pegmafite dyke swarms. While lithium values and observafions have

not as yet proven the presence of high- grade spodumene bearing pegmafites, the broadly distributed

lithium anom alies may indicate the presence of a ferfile local environment for hosfing a spodumene

bearing dyke swarm.

Phase 1 drilling was performed by Forage et Construcfion Muskw, a joint venture between Forage Fusion

Drilling and the Cree community, represented by Saskounan. Muskw, based in Chisasibi, Quebec, 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 grafitude to Muskw for their experfise, professionalism, and dedicafion to the project.

Mark Ferguson, President and CEO of Arbor commenfing “The posifive markers from our Phase 1 drilling

program have given us a solid foundafion to build upon as we confinue to explore the lithium potenfial at

Jarnet. We are confident our upcoming program will provide addifional crifical informafion 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, Corvefte, and St. Pierre claims.”

Arbor is commifted to conducfing all of its explorafion acfivifies with a strong focus on environmental

stewardship. The Company adheres to industry-leading environmental guidelines and strives to minimize

its environmental footprint. Furthermore, Arbor confinues to work collaborafively with local communifies

and other stakeholders to ensure its acfivifies are aligned with the needs and concerns of the communifies

in which it operates.

About Arbor Metals Corp.

Arbor Metals Corp. is a mining explorafion company focused on developing high-value, geographically

significant mineral projects worldwide. Arbor is paving the way for advanced mineral explorafion as it

oversees world-class mining projects. The Company is confident that combining quality projects with

proven strategies and a dedicated team will yield excepfional outcomes.

The Jarnet, Corvefte 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

configuous to the Corvefte-FCI property, where diamond drilling has confirmed significant lithium

mineralizafion represenfing one of the highest-profile lithium explorafion 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 similarifies 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 pegmafites

hosted in metasediments.
