International Lithium Provides Update on Exploration

Strategy For Mavis Lithium Project, Ontario, Canada

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 (“Pione er”) (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 Com pany’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% Li 2O 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% Li 2O over 16.55 metres from 74.55 metres and 1.40% Li 2O 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, f our 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% Li 2O over 26.30 metres from 111.9 metres,

including 2.97% Li 2O over 7.70 metres with one sample grading 4.20% Li 2O over 1.15

metres.

To date, the drilling in the Pegmatite 6 target area has drill tested a ho rizontal strike

length of 60 metres and down dip to a maximum depth of 145 metres below surface.

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 sig nificantly 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."
