The James Bay region is prolific for its hard rock lithium endowment, hosting numerous spodumene showings, four deposits with defined resources: Whabouchi (Nemaska Lithium), Rose (Critical Elements), Cyr (Allkem) and Moblan (Sayona), as well as more recent discoveries such as Corvette (Patriot Batteries Metal) and Anatacau (Brunswick Exploration).
Most deposits, occurrences and lithium showings are close and along Collision Zones between sedimentary basins such as Nemiscau and geological subprovinces.
The JBLi consists of a total of 161 mineral claims comprising approximately 8,309 hectares (83 km2) straddling along the Nemiscau sedimentary basin in contact with La Grande and Opatica geological subprovinces, Quebec.
All claims are located within close proximity to the James Bay Billy-Diamond highway and are mostly accessible by a network of secondary roads.
JBLi HIGHLIGHTS
- Exceptional positioning of lithium properties along collision zones provides an important competitive edge. The three JBLi properties are all associated to major and multiple shear zones that favor fluid migration of lithium-bearing pegmatitic magmas. All properties host mafic rocks such as basalts and amphibolites, evidencing potential mineralization entrapment. In addition to reported lithium pegmatite occurrences, beryl showings are present in all properties and represent important pathfinder minerals for lithium mineralization.
- Transformative acquisition leading to resource development drilling. The Company plans to initiate an aggressive exploration campaign consisting of an airborne geophysical survey coupled with satellite imagery processing that will identify detailed promising targets. Prospecting of such promising areas within properties will lead, once necessary permits are received, to drill priority targets.
- Advantageous location near road infrastructure. The Lac Colomb, Lac Des Pointes, and Lac Mezières claim blocks are all located adjacent or within close proximity to Billy Diamond highway and each claim block is mostly accessible by a network of secondary roads.

GEOLOGICAL SETTING SUMMARY
- Pegmatites in collision zones come from a low temperature, very fluid and elusive magma that can travel many kilometres from the source, crosscutting most existing rock Formations. In James Bay, lithium occurrences are mostly associated to collision zones.
- All lithium deposits and occurrences are closely and spatially associated to shear zones that favor fluid migration of lithium-bearing pegmatitic magmas.
- Lithium deposits tend to form at or near the contact of mafic, ultramafic or amphibolite rocks, evidencing entrapment.
- Pegmatite bodies are relatively narrow bodies up to 40 metres wide that can extend over 1,000 metres without any magnetic signature. However, they appear to be structurally controlled.
- Mineralized pegmatites can be parallel or perpendicular to shear zones and often occur as swarms.

EXPLORATION STRATEGY SUMMARY
- Fly detailed airborne geophysical survey for detecting shear zones and structures, near intraplate collision zones.
- Identify mafic volcanics and amphibolites for possible host rocks.
- Use remote sensing techniques for detecting lithium-bearing rocks.
- Ground prospecting on focused areas, close to shear zones, in order to quickly discover potential lithium-bearing pegmatites:
- A whole Property would then be screened by prospecting 15% of its size.
- Fast tracking to reach the drill-ready stage.
- Lac Colomb, Lac des Pointes and Lac Mezières Properties have all reported beryl showings and pegmatite occurrences.
