NEWS RELEASE

ARBOR METALS COMMENCES PHASE 3 DRILLING AT JARNET LITHIUM PROJECT

Vancouver, Canada – June 11th, 2025 – Arbor Metals Corp. (“Arbor” or the “Company”) (TSXV: ABR, FWB:

432) is pleased to announce the commencement of its Phase 3 diamond drilling program at the wholly

owned Jarnet Lithium Project, located adjacent to Patriot Battery Metals’ Shaakichiuwaanaan Property

(formerly known as the Corvette Project), in the Eeyou Istchee James Bay region of Quebec.

Building on the success of earlier exploration phases, this Phase 3 drilling program will target areas at

Jarnet 2, along with high-value targets on the Firebird, Corvette, and St. Pierre claims. The drilling

campaign is set to last approximately six weeks and will involve 10 setups, with a total of 12 drill holes,

estimated to reach a combined length of 3,000 meters.

“We are excited to begin Phase 3 of the drilling program at the Jarnet Lithium Project,” said Mark

Ferguson, President and CEO of Arbor. “The expansion of drilling to additional targets, including the

Firebird, Corvette, and St. Pierre claims, underscores the growing potential of the Jarnet property. We are

confident this phase will help us continue to build on the positive results from previous drilling and move

the project closer to defining its lithium potential.”

Drilling will be performed by Forage et Construction 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 extends its

sincere gratitude to Muskw for their expertise, professionalism, and dedication to the project.

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 indigenous

groups and other stakeholders to ensure its activities are aligned with the needs and concerns of the
