Vancouver, B.C. October 17, 2017: International Lithium Corp. (the “Company” or “ILC”) (TSX VENTURE: ILC) is pleased to announce, with strategic partner Pioneer Resources Limited (“Pioneer”) (ASX: PIO), and further to the Company’s news release of April 11, 2017, an update on the Mavis Lake Lithium Project in Ontario, Canada.

Drilling at the Mavis Lake Lithium Project (“Mavis”) conducted in February 2017 under the direction of Pioneer (the Company’s strategic partner) resulted in several key intersections at the Pegmatite 6 Target Area (Fig. 1).

 Key Intersections from the Pegmatite 6 Target Area*:

• 1.47% lithium oxide (“Li₂O”) over 17.90 metres* from 80.00 metres in drill hole MF17-39;

• 1.70% Li₂O over 26.30 metres from 111.9m in drill hole MF17-49, including a zone grading 2.97% Li₂O over 7.70m; and
• 1.45% Li₂O over 16.55 metres from 74.55 metres and 1.40% Li₂O over 23.10 metres from 122.00 metres in drill hole MF17-50.

* All widths reported are drill core widths and have not been converted into true width.

Pegmatite 6 Target Area

As previously reported, four holes were drilled during the campaign to follow up on mineralization encountered in previous drill holes MF-11-12 and MF-12-24 (see Company news releases dated January 12, 2012 and February 19, 2013). Each of the new drill holes intersected spodumene-bearing pegmatites of varied thickness (Table 1).

Drill holes MF17-49 and MF17-50 intersected zones of mineralized pegmatite at deeper depths than previously encountered and represent a new discovery at the Mavis Project. Hole MF17-49 returned 1.70% Li₂O over 26.30 metres from 111.9 metres, including 2.97% Li₂O over 7.70 metres with one sample grading 4.20% Li₂O over 1.15 metres.

To date, the drilling in the Pegmatite 6 target area has drill tested a horizontal strike length of 60 metres and down dip to a maximum depth of 145 metres below surface.

*All widths reported are core widths and have not been converted to true widths.

The companies now report that a crew will be dispatched to follow up on and ascertain adequate locations for the next round of drilling to occur at the Pegmatite 6 target area.

“The new deeper discoveries at the Pegmatite 6 area is cause for our joint venture partner, Pioneer Resources to investigate the prospectivity of this target in more detail in upcoming drilling campaigns,” stated Kirill Klip, Executive Chairman of ILC. “To build on the successful discoveries here at Mavis Lake will add significantly to our concept of the Upper Canada Lithium Pool. Our strategy to utilize strategic partnerships to advance projects with the ultimate goal to secure lithium supply for the ongoing electrification of our transportation and energy storage applications is proving to be successful.”
