Overview

The Gullwing – Tot Lake Property is located 30 km northeast of Dryden, northwestern Ontario in Webb township and can be accessed by Ghost Lake road and a series of local roads. The Property is composed of 76 mining claims totaling 1216 ha and is approximately 17 km by 1.5 km in size. The Property hosts multiple commodities: spodumene (Li), Ta-oxides, pollucite (Cs) and molybdenite (Mo).

The Gullwing – Tot Lake pegmatites are located 13 km north east of International Lithium Corp’s Mavis Lake – Fairservice pegmatites. International Lithium’s partner Pioneer Resource Limited completed 12 drill holes totaling 1,305 m on March 2, 2017 on the Mavis Lake Property with drill highlights of 1.47 % Li2O over 17.9 m and 1.70 % Li2O over 26.3 m (International Lithium, press release dated April 11, 2017).

The Property consists of multiple pegmatite dykes including: Gullwing Lake spodumene pegmatite swarm, Tot Lake spodumene pegmatite, Coates beryl-molybdenite pegmatite and about 15 Rb-Cs pegmatite dykes located in the Drope township area. The Gullwing Lake pegmatite swarm consists of a cluster of over 20 spodumene pegmatites identified in outcrop along the southeastern shore of Gullwing Lake. The largest pegmatite in the swarm is the Sleeping Giant Pegmatite which is at least 415 m long and up to 80 m wide. A total of 9 drill holes were completed on Gullwing Pegmatite swarm by Woitowicz and Glatz in 1999 (2 holes) and by Solitaire Minerals Corp in 2007 (7 holes). Drilling on the Sleeping Giant intersected 0.135 % Rb over 36.3 m, likely with abundant lithian muscovite. Purple lithian muscovite occurs throughout the Sleeping Giant pegmatites (Figure 1). Spodumene was intersected in drill core but lithium was not assayed. Manganocolumbite and manganotantalite occur in the Sleeping Giant pegmatite as Ta ore minerals.

Tot Lake pegmatite is a spodumene-subtype pegmatite up to 6 m wide and almost 50 m long. Tot Lake has 7 historic drill holes which intersected spodumene, but did not assay for lithium. Tot Lake is one of the few pollucite occurrences in Ontario indicating a very high degree of fractionation. The pollucite zone consists of abundant pollucite (Cs), pink spodumene, feldspar and quartz and local green muscovite (Figure 2). Dyke chip samples collected across two 9 m long historic trenches on the Tot Lake pegmatite contained an average grade of 1.0 % Li2O. Manganocolumbite and manganotantalite occur in the Tot Lake pegmatite as Ta ore minerals.

The Gullwing – Tot Lake Property has numerous spodumene pegmatite dykes with minimal exploration drilling and lithium assays. There is a potential to find additional pegmatite dykes over the 5 km between Gullwing Lake pegmatite swarm and the highly-fractionated Tot Lake pegmatite.
