Access Description: The Gathering Lake project can be accessed by dirt roads off Highway 11 north of the town of Nipigon. The claims are accessed by driving 40 km north of the town of Nipigon on Highway 11, then driving approximately 59 km northeast on the Gorge Creek Road (Camp 75 Rd.) and Camp 51 road. An alternative route can also utilized from Highway 11 between Beardmore and Geraldton, ON along the Camp 51/Sturgeon River Road towards Gathering Lake for approximately 28km southwest.
1955: Standard Lithium optioned the property from E. Nelson and drilled 12 holes totaling 366.7 m. 2018: K. Fenwick and A. Pleson carried out prospecting and sampling. 2022: A. Pleson carried out channel sampling and a VLF-EM survey. 2023: Balkan Mining and Minerals Ltd optioned the property and carried out soil sampling.

Geological Age: Neoarchean
Oct 06, 2021 (Therese Pettigrew) - Geologically, the area is located within the Quetico Subprovince of the Superior Province. The Quetico Subprovince is composed of predominantly metasediments consisting of wacke, iron formation, conglomerate, and siltstone, which deposited between 2.70 and 2.69 Ga. The Quetico Subprovince was subjected to four deformational events between approximately 2700 and 2660 million years. Metamorphism, migmatite formation and granite intrusion occurred between 2.67 and 2.65 Ga (Williams, 1991). The igneous rocks in the Quetico Subprovince include abundant felsic and intermediate intrusions, metamorphosed rare mafic and felsic extrusive rocks and an uncommon suite of gabbroic and ultramafic rocks. The earlier felsic intrusions occurred 5 to 10 million years after the accumulation of sediments and are interpreted to be I-type intrusions. The later felsic intrusions occurred 20 million years after the sedimentation and are designated as S-type. The pegmatites in the Quetico Subprovince which contain lithium and rare metals (beryllium, tantalum, niobium and tin) are hosted by metasediments and by their parent granite. The pegmatite dykes, sills and lenses can be subdivided into rare-element pegmatites and granitic pegmatites. The rare-element pegmatites are of economic significance and they contain microcline or perthite, albite, quartz, muscovite and spodumene and minor amounts of beryl, columbite-tantalite and cassiterite. The granitic pegmatites are like the irregular pegmatites described above except that they contain more abundant plagioclase. Some of the pegmatites are parallel to the foliation or bedding of the metasediments, whereas others occur in joints in either the metasediments or granite. Contacts are usually sharp and, except where dykes cut granitic rocks, often found to be marked by a thin border zone of aplite or granitoid composition. A few pegmatites are internally zoned with mica-rich or tourmaline-rich rock along or close to the walls and quartz cores (Assessment report 20000017160).

Oct 06, 2021 (Therese Pettigrew) - The property is dominated by granite related to the Glacier Lake Batholith. Outcrop is limited. Overall, the granite is mainly coarse-grained consisting of quartz, feldspar, and muscovite. The metasediments observed are typically meta-sandstone described as a muscovite schist with observed bedding and various stages of metamorphism are present, including migmatization imparting a gneissic texture. The pegmatites at the Nelson occurrence display partial zoning, with a spodumene zone observed on the western portion of the large pegmatite outcrop/hill.

Oct 06, 2021 (Therese Pettigrew) - In the 1955 drill program, DDH 4 returned 0.06% Li over 15 feet, DDH 6 returned 0.18% Li over 5 feet, and DDH 7 returned 0.36% Li over 5.8 feet (Assessment report 42E06NW0002). The Nelson area is dominated by a feldspar-muscovite pegmatite with trace beryl. John Scott sampled the pegmatite and received values of up to 202.9 ppm Li. The low-grade enrichment of Li is not economic but provides evidence that there is a potential for discoveries of spodumene bearing dykes in the area based on fractionation observations. The west side of the large FM-pegmatite is cut by a small NNE-striking, shallow dipping, 2 m wide spodumene-bearing pegmatite dyke. This area was selectively sampled and returned a value of 3.22% Li2O (Assessment report 20000017160). The best assays from the 2022 channel sampling program returned 1.82% Li2O over 1.1 m (Assessment report 20000020927).
