Leaf River

Manning controls a district-scale portfolio of exploration projects situated in the emerging Leaf River lithium camp. Leaf River is located 200 km WSW of the community of Kuujjiaq, QC (Figure 1).

The four separate projects, named “Snap”, “Crackle”, “Pop” and “Pow”, comprise a combined 65,785-hecatres (1,426 mineral claims). Several companies are now active in the area with multiple large land acquisitions having taken place in recent months.

The acquired claims cover some of the highest (99% percentile) lithium, cesium, and rubidium lake sediment anomalies in the entire Government du Quebec lake sediment database (SIGÉOM) that sit within favourable geological hosts of leucotonalites, granites, gneiss, and mafic basalts units.

The highly elevated lake sediment samples over favourable geology associated with regional magnetic structure and documented pegmatites represents an optimal environment for rare-element pegmatites.

More about Leaf

The Property is host to several known pegmatite outcrops but remains underexplored with little to no lithium -focused work having been conducted prior to Manning-Ventures.

No lithium-bearing occurrences had been noted despite several known pegmatite outcrops on the property.

Project selected as a result of a regional targeting method including a review of pegmatite occurrences across Quebec with the appropriate indicator-mineralogy and indicator-chemistry for hosting Lithium-Cesium-Tantalum (LCT) style, spodumene-bearing pegmatites, within favorable host-rocks.


Geology across all claim blocks consists of a mix of leucotonalites, granodiorites, granites, paragneiss, amphibolites, gabbros, and basalts.  The magnetic data highlights NW and WNW trending structures which make excellent pathways for fractionating fertile parental melts.

The area is historically underexplored for lithium and presents a compelling ground-floor opportunity for significant discovery.

Snap Project

The Snap project consists of 396 claims covering 18,364-ha, with three mapped pegmatites. Thirteen (13) lake sediment samples have been collected containing over 28.5 ppm Li (97% percentile), 3 samples over 37.3 ppm Li (99% percentile), 2 samples over 40.1 ppm (99.31% percentile) and 1 sample over 47.8 ppm (99.78% percentile). The ground also contains multiple Cs levels in the 3 ppm (97% percentile) to 6.35 ppm (99.89% percentile) range, and multiple Rb levels over 46 ppm (97% percentile) *.

Crackle Project

Crackle comprises 376 claims covering 17,432-ha, with four mapped pegmatites. Twelve (12) lake sediment samples have been collected reporting over 28.5 ppm Li (97%), with 5 samples over 37.3 ppm (99%), and 3 samples over 45.5 (99.69%). Crackle also contains multiple elevated Cs levels in the 3 ppm (97%) to 4.8 ppm (99.64%) range, and multiple Rb levels in the 46 ppm (97%) to 92.7 ppm (99.76%) range.


Pop contains 241 claims covering 11,113-ha, with two known pegmatites. Eight (8) lake sediments samples have been collected in the claim group reporting over 28.5 ppm Li (97%), 4 samples over 37.3 ppm (99%), 2 samples over 46.8 ppm Li (99.74%). The highest lake sediment sample on the property returned 50.6 ppm Li (99.84%). Pop also contains multiple Cs levels in the 3 ppm (97%) to 5.31 ppm (99.79%) range, and multiple Rb levels in the 46 ppm (97%) to 80.3 ppm (99.53%) range.
