Pinnacle Minerals Ltd is pleased to announce significant advancements at its Adina East Lithium Project, located in the James Bay region of Quebec, Canada. The company has completed a LIDAR and orthophoto survey, identifying several high-priority targets showing strong lithium mineralization potential.
Highlights:
- Multiple pegmatite targets have been identified from recent LIDAR and orthophoto survey at the Adina East Lithium Project in Québec, Canada
- Priority targets on the Western flank of the project are located within the same metasedimentary rock sequence as the Loyal Lithium Trieste discovery (31.8 m at 2.2 % Li2O)1
- Eastern targets are interpreted to be an extension of the Tilly Pegmatites associated with the Winsome Resources Tilly discovery, which yielded assays of 7 m at 4.68 % Li2O2
- No prior sampling has been conducted on the outcrops which stand out as high-quality regional targets based on current data
- LIDAR combined with high-resolution orthophotos has previously been successfully used in the discovery of spodumene-bearing Pegmatites in the James Bay region of Quebec
- Pinnacle is currently devising a field program to map and sample these targets with a view to trenching and or drilling the targets should spodumene be identified
Pinnacle Minerals Managing Director, Nic Matich, commented: “The use of LIDAR coupled with the Orthophoto survey has enabled the Company to rapidly and cost-effectively identify the most prospective areas of the project. Our exploration team can now mobilize via helicopter directly to the target outcrops, which increases our probability of discovery.”
Project Overview: The Adina East Project encompasses 147 claims over 72.7 km² and is adjacent to several significant lithium projects, including Loyal Lithium’s Trieste Project and Winsome Resources’ Tilly Project. These neighboring projects have reported substantial lithium-bearing pegmatite dykes, indicating a promising geological setting for Adina East.
Survey Results: The LIDAR and orthophoto survey successfully identified key targets on both the eastern and western flanks of the project. Notably, rubidium enrichment up to 658 ppm was obtained from rock chip samples on a granitic pegmatite, indicative of magmatic fractionation, which is a precursor to lithium saturation. The critical "fractionation ratios" of K/Rb below 100 suggest the potential for spodumene-bearing pegmatite trending northwest into the project's metasedimentary rocks.
Next Steps: Pinnacle Minerals is currently in discussions with a local Quebec-based geologist to mobilize to the project site for detailed mapping and rock chipping of the identified targets. This strategic move will facilitate a thorough evaluation of the prospective areas, significantly advancing the exploration timeline for 2024.
