Arbor Metals Intersects Anomalous Lithium Mineralization up to 0.58% Across 2 Target Zones at Jarnet Lithium Project

(TheNewswire)

Vancouver, Canada– TheNewswire - January 15th, 2026– ArborMetals Corp. (“Arbor” or the“Company”) (TSXV: ABR, FWB: 432) is pleased to announce assay results from its 2025 Phase 3diamond drilling program at its wholly owned Jarnet Lithium Project,located in the Corvette Lake Lithium Camp, Eeyou-Istchee Baie-Jamesterritory in the Quebec North region. Anomalous lithium wasencountered on the Jarnet 2 and Corvette claim blocks.

Several intervals of anomalous lithium was identifiedwithin pegmatite dykes.

• On the Jarnet 2 claim blocks samples from JAR25-014 (atthe northern extent of the Prince Zone) and JAR25-015, were orientedto test an over 200m wide series of pegmatites, both intersectedanomalous 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 contactsbetween greenstone and peridotite also intersected anomalous lithium.The three mineralized intersections are a series of parallel dykes. 

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

  • JAR25-030 intersected  

    • 0.50m grading 1278ppm (~0.12%) lithium at a depth of73.5m 

    • 0.50m grading 5841ppm (~0.58%) lithium at a depth of130.24m 

    • 0.57m grading 2276ppm (~0.22%) lithium at a depth of203.71m

In addition, several intervals of anomalous REEelements and base metals, such as nickel, copper and molybdenum, wereidentified.

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

The Company expects its assay results from its Fall2025 bark sampling program, which was conducted at the Corvette clamblock around recent drilling, in Q1 of 2026.

Background

The Phase 3 drilling campaign saw the completion of 10NQ holes, with a combined drilling length of 2,451 meters. Drillingdepths ranged from 137 meters to 462 meters, with approximately 572samples collected during the program including QA/QC samples. Thedrilling program was carried out by Muskw Drilling, a local jointventure with the Cree community.

The majority of drillholesencountered numerous pegmatite dykes hosted either by granitoids orgneissose sediments and volcanics. In general, pegmatites were 0.5m to2.0m 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 of46.84m in JAR25-019. JAR25-033 passed through a gneissose mafic unitand did not see any pegmatites.

Drill core assay results indicate the presence oflocalized lithium and rare earth element enrichment, however,Li-enrichment and REE enrichment are not spatially or geochemicallycoupled. Lithium values are highly variable, ranging from backgroundlevels (<50ppm) to locally elevated values up to 5861ppm Li. Thedistribution of Li values is strongly skewed, with a small number ofvery high-Li intervals which occur in individual samples, suggestinglocalized Li enrichment in zones of highly evolved magmaticdifferentiation in pegmatites or late-stage granitic phases.Additionally, there are several samples with high Li values areassociated with elevated Cs, Rb, Ta and Nb, consistent with LCT-typepegmatites.

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

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

Samples were delivered to SGS Laboratories, andarms-length laboratory in Val d’Or, and were analyzed using“GE_ICP90A50 & GE_IMS90A50 Sodium Peroxide Fusion / CombinedICP-OES and ICP-MS Package”. Sampling was done without crossinglithological boundaries. Quality control blanks and standards wereadded during the core logging process, including quartz blanks andCDN-Li-1 and CDN-Li-2 standard reference materials.

About Arbor Metals Corp.

Arbor Metals Corp. is a mining explorationcompany focused on developing high-value, geographically significantmineral projects worldwide. Arbor ispaving the way for advanced mineral exploration as it overseesworld-class mining projects. The Company is confident that combiningquality projects with proven strategies and a dedicated team willyield exceptional outcomes.

The Jarnet, Corvette Lake and St. Pierrelithium projects, located in the James Bay region of Quebec,comprises 83 map-designated claims, covering an area of approximately5,606 hectares. The projects are contiguous to the Corvette-FCIproperty, where diamond drilling has confirmed significant lithiummineralization representing one of the highest-profile lithiumexploration projects in the sector.

The Kemlee LakeLithium project isstrategically located three kilometers east of Rock Tech LithiumInc.'s Aumacho claim blocks and twelve kilometers south of theGeorgia Lake Project.  The Project shares many geologicalsimilarities with the prolific Georgia Lake deposit, including bedrockgeology and the presence of massive intrusive dykes. The primarytarget at the Project will be spodumene-bearing pegmatites hosted inmetasediments.
