Project, Argentina

Vancouver, B.C. August 28, 2017: International Lithium Corp. (the “ Company” or

“ILC”) (TSX VENTURE: ILC) is pleased to announce , with JV partner Ganfeng Lithium

Mariana Lithium JV Update

Further to the Company’s news release dated April 10 , 2017, announcing a maiden

resource estimate for the Mariana lithium brine project , the following activities have

been ongoing at the project site as the project advan ces toward the commencement of

preliminary economic and pre-feasibility studies.

On April 25, 2017, the Company was informed by manager of the Mariana Joint Venture

that three large evaporation ponds measuring 14 x 14 metres have been constructed at

site and filled to 30 centimetres depth with raw brine from Salar de Llullaillaco to

conduct large scale evaporation tests and begin the development of a natural

evaporation concentration process for the brine. Two smaller ponds that are to be used

for the lat er stages of the brine concentration were also constructed at the site. A field

laboratory and l iming plant are currently under construction with the field laboratory

expected to be completed by the end of August or early September and the liming plant

targeted for mid-September.

A series of snow storms in the property region in late May and early June, 2017

seriously impacted access to the site and throughout the district. Access to the camp

facilities was limited to 4x4 pickup trucks during this period . Large truck access was

restored to the site by July 17, 2017.

Natural evaporation concentration field t ests continued through June and July with

recorded evaporation rates reported to be low due to the cooler temperatures and the

introduction of freshwater into the ponds by snowfall events.

Environmental impact studies were completed in the period and a draft report is

expected by the end of August.

Upcoming work consists of geoph ysical surveys, including electromagnetic surveys to

highlight possible freshwater sources and a second phase of gravity surveying to

provide a more complete map of the depth of the basin.

Pumping test well MA17 -20PW (Figure 1) was drilled to an approximate depth of 232

metres before being placed on hiatus in May due to the winter storms . It will now be

completed to its final depth of 256 metres. Pump test results will be reported as they

become available.
