INTERNATIONAL LITHIUM RECEIVES ENCOURAGING PUMP TEST RESULTS ON MARIANA LITHIUM BRINE PROJECT, ARGENTINA

International Lithium Corp. has received a report prepared by Geos Mining Minerals Consultants of Australia through ILC's joint venture partner, Mariana Lithium Co. Ltd., a subsidiary of Jiangxi Ganfeng Lithium Co. Ltd. The report summarizes results from trial pump tests conducted in September, 2017, at Salar de Llullaillaico, the location of the Mariana lithium-brine joint venture project in Salta, Argentina. The trial tests are part of continuing pump tests to be completed at three locations on the project. A conclusion from the trial pump test report stated, "A step-drawdown test pumped at three rates of between 10 and 30 litres per second indicated a high transmissivity, hydraulic conductivity and storativity." The ultimate goal for these continuing tests is to carry out long-term pumping at a constant rate of 60 L/s at three sites within the resource area. The company will provide further updates on the progress of these tests.

Highlights of the study results from the Geos report:

• Litio Minera Argentina SA conducted trial pump tests on bore MA17-20PW, located in the Mariana project, western Salar de Llullaillaco, resource area during September, 2017. An exploratory aquifer test with observation bores was conducted to provide training and understanding to staff, preliminary aquifer drawdown and response assessment, and a step-drawdown test to provide information on well efficiency.
• Initially a constant-rate test utilizing five observation bores was conducted for a five-hour period pumping at 30.4 L/s. Minor drawdown was observed in observation bores monitoring both higher and lower parts of the aquifer system. No drawdown was observed in more distal observation bores.
• The lack of drawdown in shallower observation bores and the one deeper observation bore (MA17-20A) indicates that the pumped aquifer at the level of MA17-20B is acting in a nearly confined manner, and there was minimal interaction over the short pumped time period with overlying or underlying aquifers.
• A step-drawdown test pumped at three rates of between 10 and 30 L/s indicated high transmissivity, hydraulic conductivity and storativity.

Though no modelling of the drawdown from the trial pumping tests was completed, preliminary graphical analysis suggests the salar's interlayered and intercalated sedimentary package makes up an interconnected leaky aquifer system at site MA17-20PW. This aquifer system has a very high transmissivity, high hydraulic conductivity and a significant storativity.

"The ongoing confirmation that the aquifers at Salar de Llullaillaco can sustain extending pumping are complementary to our goals of achieving a positive production decision through upcoming preliminary economic assessment and feasibility studies," commented Kirill Klip, executive chairman of International Lithium. "These tests pave the way for us to determine the best technology and economic scenario to advance our Mariana lithium joint venture project."

At Mariana, the current focus for lithium extraction is to determine the break points of contaminants such as magnesium and sulphate in the natural evaporation process in order to define the timing of the liming process. The large quantities of lime and other reagents needed to neutralize the brine chemistry to prevent the loss of lithium through precipitation during the evaporation concentration process generally tend to have a severe negative impact on the economics of lithium-brine operations.

In its news release of Sept. 5, 2017, the company released results of an early study regarding the utilization of membrane technology to produce a high-value lithium product. The adoption of alternative technologies such as described in the Sept. 5, 2017, news release has the potential to provide an alternative to the currently adopted plan of using natural solar evaporation to produce a brine concentrate that would be exported to China for further refining.

The Mariana lithium joint venture partners are currently reviewing options for the 2018 budget year that are aimed at accelerating the project through the studies required to prove economic viability.
