Toivo

Owner: Libra Energy Materials (100%)
Project Size: 9,448 ha
Project Location: ~50km SE of Pickle Lake, ON

Project Summary: The Toivo project was staked by Libra in July 2024 following a highly successful ~2-week prospecting program at the nearby SBC project in June 2024, which resulted in the discovery of 18 new spodumene occurrences with grab samples returning up to 6.64% Li2O and spodumene-bearing dykes up to 30m wide (Fig. 1). These results led to the formation of a strategic partnership with KoBold Metals on the SBC project. Strategically located along the Uchi Subprovince boundary in the Lake St. Joeseph greenstone belt and trending along strike of the Greenbush Lithium occurrence which has returned 15m @ 1.25% Li2O from a historic chip sample. Historical maps show the presence of pegmatite dykes on the property, but no exploration work focused on lithium has ever been documented. The property is located approximately 50km south of the full-service town of Pickle Lake, ON, and is only ~15km to the east of four-season Highway 599 (Fig. 1).

Geology

The Toivo project lies within the Archean-age Lake St. Joseph greenstone belt of the Uchi Subprovince. The following is an excerpt from Jensen (1991) on the geology of the Caron Lake area –

The supracrustal rocks comprise interlayered clastic sedimentary rocks, calc-alkalic fragmental volcanic rocks, tholeiitic volcanic flows and units of magnetite-rich arenite, iron formation and komatiite. In both the Uchi and English River subprovinces, the supracrustal rocks have been subjected to middle to upper amphibolite facies of metamorphism and to intense deformation. Large tonalite-trondhjemite stocks intrude the supracrustal rocks. White, granitoid pegmatite forms metre- to kilometre-sized sills, dikes, and stocks within the sedimentary rocks. The most abundant rocks within both the south half and north half of the Caron Lake area are quartzose sedimentary rocks, metamorphosed to paragneisses and (staurolite – sillimanite) schists that are intruded by sills, dikes and stocks of granitic pegmatite.

Results from the SBC project have shown that the spodumene pegmatites intrude both sedimentary and volcanic rocks in the region.

Next Steps

Current and future work at the Toivo project includes flying a LiDAR survey over the property followed by a 2-week reconnaissance prospecting program with the goal of identifying spodumene mineralization on surface that is set to take place during Fall 2025. Future drilling will be contingent on the success of the preliminary field work.
