Summary
The Frontier District Projects is comprised of Borland East** (175 ha), Borland North** (1,012 ha), Borland West (351 ha), Favourable Lake (682 ha), North Trout (3,490 ha), Margot Lake (1,393 ha), and MacDowell Lake (4,137 ha) located in the northwest Ontario along the same regional structure that hosts the Pak and Spark lithium deposits owned by Frontier Lithium (FL.V). The PAK deposit has a probable mineral reserve of 4 MT averaging 1.79% Li2O; the deposit hosts a rare technical/ceramic grade spodumene with low inherent iron (below 0.1% Fe2O3). The Spark Deposit has a probable mineral reserve of 18 MT averaging 1.5% Li2O.These projects are mainly accessed by helicopter with local logging roads.

Exploration
The Bear Head Lake Fault Zone appears to be the locus for a peraluminous suite of granitic plutons. To date based on research in the region, nine major plutons consisting of two mica granites (fertile granites) are documented over the 140 km strike length of the fault; fertile granites are interpreted to be the parental rocks that give rise to rare metal pegmatites. Also, the Bear Head Lake Fault Zone also acts as a subprovince boundary between the Berens River and Sachigo Subprovinces, two of the greenstone belts are located and divided by this structure. The Favourable Setting Net Lakes greenstone belt is hosted to the northeast of the boundary and the North Spirit Lake greenstone belt is hosted to the southwest of the boundary.
The presence of the regional Bear Head Lake Fault Zone and of the two greenstone belts has made this region to be favorable for LCT pegmatites exploration. The seven projects in the Frontier District are located along this structure. Beyond Lithium’s field team only prospected the Margot Lake Project for 2 field days in 2023 due to the shortage of helicopter access from forest fire in Ontario. Prospecting programs are planned to explore the Frontier District Projects in the next exploration program.
