Highlights
- Strong lithium soil geochemical anomaly 1,100m long by 100m on the east widening to 350m at the west.
- Potential for additional tonnage.
- Several areas reported over 1,000 ppm Li.
- Chip samples in the area are 2.47% Li2O at Mapetre and 4.16% Li2O at Central.
- Magnitude of lithium anomaly cannot be accounted for by the known pegmatites in the area.
- Lithium market moving into deficit with material shortages emerging.
The historic assessment report (Manitoba Mines Branch: #92681) documents a litho-geochemical soil survey that was conducted by TANCO for the purpose of delineating buried, undiscovered tantalum-bearing pegmatite structures that may occur south of
The second grid (Grid "B") established a tighter, 150 x 150-foot grid pattern over the western portion of the Grid "A" anomaly. The purpose of Grid "B" was to again identify additional pegmatite mineralization in extensions of, or parallel structures to the Central Dike. Results of the lithium soil geochemistry were highly anomalous as several areas reported over 1,000 ppm lithium concentrations with a widespread lithium anomaly showing > 300ppm Li and remaining open ended to the east.
The location of both these grids and the data TANCO produced are reproduced in the figure below.
In the assessment report, TANCO geologists state that the "breath and length of this lithium anomaly is such that it cannot be accounted for by the known pegmatites in the area." TANCO geologists strongly recommended that the company explore both these target areas with additional drill programs; however, at the time, tantalum was TANCO's metal of choice and the company had no interest in producing lithium. The assessment report was prepared by
QMC's exploration work programs have confirmed the presence of significant mineralization within the Mapetre and Central pegmatite dikes. QMC crews identified large crystals of spodumene mineralization on the Mapetre where a 1.5-metre-long chip sample assayed 2.47% Li2O. Chip samples from the Central assay returns were from 1.42% to 4.16% Li2O. QMC also had TANCO drill core assayed for lithium. The best Mapetre Dike intersection was 0.32% Li2O over 16.61 metres, including 0.52% Li2O over 8.69 metres. The best intersection from the Central Dike was 1.28% over 3.81 metres, including 2.97% Li2O over 1.22 metres. Two additional sample intervals from drill holes on the Central Dike re-assayed 1.50% Li2O over 1.52 metres and 1.04% Li2O over 1.52 metres.
