Vancouver, Canada, Arbor Metals Corp. has announced the results of its Phase 1 2026 diamond drilling program at the Jarnet Lithium Project in Quebec, Canada. The program, conducted over the first quarter of the year, drilled five holes totaling 1,433 meters, revealing significant lithium and rare earth element (REE) mineralization.
The drilling program targeted a prominent linear lithium anomaly identified in the 2025 Bark Sampling program, with holes JAR26-37 to JAR26-39 focusing on the Jarnet 2 claim block. Holes JAR26-40 and JAR26-41 were drilled to build on elevated lithium values from previous exploration efforts, which had yielded several significant pegmatite intercepts.
Among the notable findings, hole JAR26-39 returned a best result of 307.7 parts per million (ppm) TREE over 1.00 meter from 119.00 to 120.00 meters, while hole JAR26-37 produced 260 ppm Li over 0.61 meters from 227.39 to 228.00 meters. The program returned 56 samples grading greater than 150 ppm lithium, ranging from 151 to 260 ppm Li, with an average of 174.8 ppm Li. Eight samples exceeded 200 ppm Li, with the highest result being 260 ppm Li over 0.61 meters in JAR26-37.
The lithium grades showed little correlation with rare earth tenor, indicating that the lithium and REE systems at Jarnet are decoupled. The drilling program covered a total of 122 reported intervals across the five holes, with total rare earth element (TREE) grades ranging from 95.4 to 307.7 ppm, averaging 166.2 ppm. The best result, 307.7 ppm TREE over 1.00 meters in JAR26-39, also featured a heavy-rare-earth-rich signature with 185.0 ppm HREE.
The results indicate a broad low-grade REE-enriched envelope across all five holes. Higher-grade material, while more selective, showed several intervals above 200 ppm TREE, including 242.3 ppm TREE over 0.57 meters in JAR26-41 and 233.2 ppm TREE over 1.50 meters in JAR26-40. The Company considers the HREE-weighted signatures from several intervals, such as JAR26-39 (119.00-120.00 meters), JAR26-41 (16.37-17.85 meters), and JAR26-41 (182.43-182.93 meters), warrant further investigation.
Mark Ferguson, President and CEO of Arbor Metals, stated, "Our Phase 1 2026 drill program has provided us with a substantial new dataset at Jarnet. The program has returned significant results, including 260 ppm Li over 0.61 meters in JAR26-37 and 307.7 ppm TREE over 1.00 meters in JAR26-39. The broad low-grade REE envelope and the presence of several HREE-weighted intervals will guide our future exploration efforts."
The drilling was performed by Forage et Construction Muskw, a joint venture between Forage Fusion Drilling and the Cree community. Muskw, based in Chisasibi, Quebec, is co-owned and predominantly operated by local and Indigenous stakeholders. Their involvement exemplifies Arbor's commitment to community engagement and economic development in the regions where it operates.
Arbor Metals Corp. is focused on developing high-value, geographically significant mineral projects worldwide. The Jarnet, Corvette Lake, and St. Pierre lithium projects, located in the James Bay region of Quebec, cover an area of approximately 5,606 hectares and are contiguous to the Corvette-FCI property, known for its significant lithium mineralization.
Ferguson concluded, "We will use these results to refine our targeting for the next phase of exploration at Jarnet. Our commitment to environmental stewardship and community engagement remains strong as we continue to advance the Jarnet Lithium Project."
