Nemiscau
Project Location Description:
The Nemiscau property is in the James Bay region in northern Quebec, approximately 410km north of the city of Val-d’Or (Fig. 1).
Although the property would require helicopter support for access, it is only ~17 km to the east of the James Bay sealed highway and ~60km to the west of the Nemiscau airport.

Geology

The Nemiscau property is located in the Eastmain subprovince near James Bay in northern Quebec. Most of the property is mapped as being underlain by a rose pegmatitic granite that is in contact with a biotite-bearing granite (to the west). Key outcrop descriptions from Nemiscau are as follows:
- Outcrop 402028 is described as being pegmatite (rock code I1G) for 98% of the exposure, having a width of 10-50 meters
- Outcrop 402029 is described as being pegmatite (rock code I1G) for 98% of the exposure, also having a width of 10-50 meters
- Outcrop 402030 is described as being pegmatite (rock code I1G) for 70% of the exposure, having a width of 10-100 meters
Project Summary
The Nemiscau property is located in the James Bay region in northern Quebec (~21km to the south of the Pontax Li Deposit (10.1 Mt @ 1.04% Li2O; Cygnus Metals-Stria Lithium). The James Bay region in Quebec is host to several world-class Li pegmatite deposits and new lithium occurrences.
Combined with the presence of wide pegmatite outcrops (up to ~100m), Nemiscau is a very attractive target with confirmed wide pegmatites that warrants attention (Fig. 2). Additionally, Nemiscau is very close to infrastructure and is only ~17km from the James Bay sealed highway and ~9.5km from Hydro Quebec powerline infrastructure.

Proposed Next Steps
Nemiscau will undergo a helicopter supported, reconnaissance mapping campaign in order to fully characterize the previously documented pegmatite outcrops as well as other outcrops that have not yet been mapped throughout the property. This may be supported by a property wide till sampling program in low-lying parts of the property to help delineate potential Li-mineralization that may not be observed in outcrop. If the results from the initial program are significant, a follow-up drill program may be executed based on the results of the previous mapping and till sampling programs.
