ARBOR METALS INTERSECTS ANOMALOUS LITHIUM MINERALIZATION UP TO 0.58% ACROSS 2 TARGET ZONES AT JARNET LITHIUM PROJECT - Arbor Metals Corp.

Vancouver, Canada – January 5, 2026 – Arbor Metals Corp. (“Arbor” or the “Company”) (TSXV: ABR, FWB: 432) is pleased to announce assay results from 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. Anomalous lithium was encountered on the Jarnet 2 and Corvette claim blocks.

Several intervals of anomalous lithium was identified within pegmatite dykes.

– On the Jarnet 2 claim blocks samples from JAR25-014 (at the northern extent of the Prince Zone) and JAR25-015, were oriented to test an over 200m wide series of pegmatites, both intersected anomalous lithium.

– JAR25-014 intersected 1.56m grading 5781ppm (~0.57%) lithium at a depth of 54.7m.

– JAR25-015 intersected 1.5m grading 2224ppm (~0.22%) lithium at a depth of 212.06m.

– On the Corvette claim blocks samples from JAR25-029, JAR25-030 and JAR25-031 were oriented to test around the contacts between greenstone and peridotite also intersected anomalous lithium. The three mineralized intersections we a series of parallel dykes.

– JAR25-031 intersected 1.14m grading 5861 (0.58%) lithium at a depth of 84.86,

– JAR25-030 intersected

– 50m grading 1278ppm (~0.12%) lithium at a depth of 73.5m

– 50m grading 5841ppm (~0.58%) lithium at a depth of 130.24m

– 57m grading 2276ppm (~0.22%) lithium at a depth of 203.71m

In addition, several intervals of anomalous REE elements and base metals, such as nickel, copper and molybdenum, were identified.

“The Company is pleased with these results as they continue to demonstrate that the Jarnet Lithium Project has the potential for high-grade lithium in two distinct areas: Jarnet 2 and Corvette,” said Mark Ferguson, President and CEO of Arbor. “The Company is undertaking a comprehensive data study of the results to refine future diamond drilling programs.”

The Company expects its assay results from its Fall 2025 bark sampling program, which was conducted at the Corvette clam block around recent drilling, in Q1 of 2026.

Background

The Phase 3 drilling campaign saw the completion of 10 NQ holes, with a combined drilling length of 2,451 meters. Drilling depths ranged from 137 meters to 462 meters, with approximately 572 samples collected during the program including QA/QC 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.

The majority of drillholes encountered numerous pegmatite dykes hosted either by granitoids or gneissose sediments and volcanics. In general, pegmatites were 0.5m to 2.0m in width (to maximums of 23.56m and 36.67m, both in JAR25-032) and constituted about 10% of each drillhole length on average. Pegmatite intervals could reach thicknesses of 10m, up to a maximum of 46.84m in JAR25-019. JAR25-033 passed through a gneissose mafic unit and did not see any pegmatites.

Drill core assay results indicate the presence of localized lithium and rare earth element enrichment, however, Li-enrichment and REE enrichment are not spatially or geochemically coupled. Lithium values are highly variable, ranging from background levels (<50ppm) to locally elevated values up to 5861ppm Li. Tables 1 and 2 below show the highlight lithium samples for the 2025 DDH on the Jarnet 2, Firebird and Corvette claim blocks. The distribution of Li values is strongly skewed, with a small number of very high-Li intervals which occur in individual samples, suggesting localized Li enrichment in zones of highly evolved magmatic differentiation in pegmatites or late-stage granitic phases. Additionally, there are several samples with high Li values are associated with elevated Cs, Rb, Ta and Nb, consistent with LCT-type pegmatites.

REE values show a strong LREE dominance, rather than HREE, typical of fractionated felsic systems and suggests control by accessory mineral phases, such as monazite and allanite.

There does not appear to be any meaningful correlation between elevated Li values and REE values, indicating that Li and REE mineralization is controlled by different mineral phases and / or distinct stages of magmatic evolution or fractionation.

About Arbor Metals Corp.

Arbor Metals Corp. 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 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 similarities 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 pegmatites hosted in metasediments.
