ARBOR METALS COMPLETES PHASE 3 DIAMOND DRILLING AT JARNET LITHIUM PROJECT

Arbor Metals Corp. has successfully completed its 2025 phase 3 diamond drilling program at its wholly owned Jarnet lithium project, located in the Corvette Lake lithium camp, Eeyou-Istchee Baie-James territory, in the Quebec north region.

The phase 3 drilling campaign saw the completion of 10 NQ2 holes, with a combined drilling length of 2,451 metres. Drilling depths ranged from 137 metres to 462 metres, with approximately 572 samples collected during the program, including QA/QC (quality assurance/quality control) samples. Samples will be cataloged and characterized before being sent for assay to be compared with other pegmatites and mineralized systems in the Corvette Lake area. The drilling program was carried out by Muskw Drilling, a local joint venture with the Cree community.

Drilling was completed across the Corvette, Firebird and Jarnet 2 claim blocks. Pegmatites were encountered in every hole, with the majority of samples collected from within pegmatite bodies. Additionally, select samples taken from chlorite-altered iron formations with veining and sulphides at Corvette will be assayed for gold, further adding to the potential of the project.

Holes JAR25-27, JAR25-32 and JAR25-33 were drilled in large batholiths intrusions located on the Firebird claims. Drilling showed generally different generations of pegmatites, which included intrusion swarms, crosscutting over significant lengths, between 10 and 20 metres.

About five kilometres to the south on the Corvette property, holes JAR25-29 and JAR25-31 intersected thin pegmatite dikes, which are generally of less than one metre. Otherwise, large intervals of disseminated sulphides (pyrrhotite and chalcopyrite) were encountered in mafic and ultramafic intrusions. The company is confident to have generated a new exploration target on ground, which had not been previously drilled.

Holes JAR25-34, JAR25-35, JAR25-36 were drilled on the Jarnet claims, following the identification of targets outside the main pegmatite trend. Hole JAR-25-35 and JAR-25-36 were drilled inside a magnetic front and multiple pegmatites were intersected at regular spacing inside granitic host rock.

"We are very pleased with the successful completion of our phase 3 drilling program at the Jarnet lithium project," said Mark Ferguson, president and chief executive officer of Arbor. "The consistent presence of pegmatites encountered throughout the drilling campaign is a positive sign for the project and we are eager to receive the assay results to better understand the lithium potential of the site. We are also excited to explore the gold potential in certain areas, which adds another dimension to the project's value. We look forward to continuing to advance 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 indigenous groups and other stakeholders to ensure that 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.
