Arbor Metals Completes Phase 1 2026 Drilling at Jarnet Lithium Project

NEWS RELEASE

ARBOR METALS COMPLETES PHASE 1 2026 DRILLING AT JARNET LITHIUM PROJECT

Vancouver, Canada – April 13, 2026 – Arbor Metals Corp. (“Arbor” or the “Company”) (TSXV: ABR, FWB:

432) is pleased to announce the completion 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). A total of 5 holes

totaling 1,433 meters were drilled. Samples were sent to ALS Laboratories in Sudbury, Ontario. Results

are expected in the near term.

The 2026 Phase 1 drill program was designed to build on promising lithium mineralization identified during

the 2025 exploration programs. Drilling efforts were concentrated on the Jarnet 2 claim block, where

holes JAR26-37 to JAR26-39 targeted a prominent linear lithium anomaly identified in the 2025 Bark

Sampling program. Holes JAR26-40 and JAR26-41 were drilled to build on elevated lithium values from

2025 drilling which yielded several significant lithium-bearing pegmatite intercepts, with the goal of

extending both strike and depth of the lithium mineralization identified in the 2025 program.

Hole depths ranged from 189.95 to 337.59 meters, and a total of 700 samples – including QAQC samples

– were collected and submitted for analysis at ALS Laboratories in Sudbury, Ontario.

This phase of 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, 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.

“We are thrilled to have completed this important Phase 1 drilling program at the Jarnet Lithium Project,”

said Mark Ferguson, President and CEO of Arbor Metals Corp. “The successful completion of 1,413 meters

of drilling is a positive step forward in advancing our lithium exploration efforts. We look forward to

receiving the assay results and continuing to explore the potential of this promising 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 and

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

communities in which it operates.

About Arbor Metals Corp.

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

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

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

proven strategies and a dedicated team will yield excepƟonal outcomes.

The Jarnet, CorveƩe Lake and St. Pierre lithium project s, located in the James Bay region of Quebec,

comprises 83 map-designated claims, covering an area of approximately 5,606 hectares. The projects are

conƟguous to the Corve Ʃe-FCI property, where diamond drilling has confirmed significant lithium

mineralizaƟon represenƟng one of the highest-profile lithium exploraƟon 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 similariƟes 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 pegma Ɵtes

hosted in metasediments.
