International Lithium Announces Multiple High-Grade Lithium Pegmatites Intersected at Mavis Lake Project, Ontario, Canada


Vancouver, British Columbia--(Newsfile Corp. - April 11, 2017) - International Lithium Corp. (TSXV: ILC) (the "Company" or "ILC") is pleased to announce, with strategic partner Pioneer Resources Limited (ASX: PIO) ("Pioneer"), and further to the Company's news release of March 13, 2017, the analytical results from the recently completed winter drill program at the Mavis Lake Lithium Project in Ontario, Canada.

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. True width of the drill hole intercepts, which may be shorter than those reported, are currently unknown.

Drilling at the Mavis Lake Lithium Project ("Mavis") commenced on February 4, 2017 under the direction of Pioneer (the Company's strategic partner) and was completed on March 2, 2017. In total, 12 oriented diamond core drill holes were completed for a total of 1,305 metres across three target areas: PEG006, PEG006.5 and PEG018 (Fig. 1).

Pegmatite 6 Target Area

Four holes were drilled during the current 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 current 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. True width of the drill hole intercepts, which may be shorter than those reported, are currently unknown.

Drill hole MF17-41 drilled at the Pegmatite 6.5 Target Area returned no significant results.

"We are very pleased with the results Pioneer have achieved at Mavis and look forward to continued exploration success," stated Kirill Klip, CEO of ILC. "Our concept of the Upper Canada Lithium Pool is moving forward and ILC has another lithium project in its portfolio moving toward a more advanced exploration stage. This success supports our strategy utilizing strategic partnerships to advance projects with the ultimate goal to secure lithium supply for the ongoing electrification of our transportation and energy storage applications."

Pegmatite 18 Target Area

Seven drill holes were drilled to test the lateral and down-dip extent of Pegmatite 18, a shallow, south-westerly dipping pegmatite that has been traced for 215 metres on surface (see Company news release dated December 1, 2016).

All seven drill holes intersected Pegmatite 18 with the intercepts varying in spodumene content (5-45%) and drill hole intersections (1.5 - 9.85m).

MF17-43 10.00 15.00 5.00 1.29  
MF17-44 12.85 18.85 6.00 0.96

MF17-47 57.45 60.45 3.00 1.27
MF17-48 - - - - no significant results


*All widths reported are core widths and have not been converted to true widths. True width of the drill hole intercepts, which may be shorter than those reported, are currently unknown.

Laboratory work was conducted by Activation Laboratories Ltd. of Ancaster, Ontario, with samples submitted by Pioneer's representatives to their preparation facilities in Dryden, Ontario. Activation Laboratories Ltd. is an ISO 17025:2005 and CAN-P-1579 certified laboratory. Analysis was performed using a Na-peroxide fusion digestions followed by an ICP-OES and ICP-MS finish.

In recent meetings of the Management Committees for the Avalonia lithium pegmatite project in Ireland and the Mariana lithium brine project in Argentina, it was decided that Ganfeng Lithium Co. Ltd., will take over the role as Manager of each project and continue to carry out the exploration work pursuant to the respective option and joint venture agreements.

About International Lithium Corp.

International Lithium Corp. has a significant portfolio of projects, strong management, robust financial support, and a strategic partner and keystone investor, Ganfeng Lithium Co. Ltd., a leading China-based lithium product manufacturer.

The Company's primary focus is the strategic stake in the Mariana lithium-potash brine project located within the renowned South American "Lithium Belt" that is the host to the vast majority of global lithium resources, reserves and production. The Mariana project, strategically encompasses an entire mineral rich evaporite basin, totalling 160 square kilometres, that ranks as one of the more prospective salars or 'salt lakes' in the region. Current ownership of the project is through a joint venture company, Litio Minera Argentina S. A., a private company registered in Argentina, owned 80% by Ganfeng Lithium Co. Ltd. ("GFL"), and 20% by ILC. In addition, ILC has an option to acquire 10% in the Mariana project through a back-in right.

Complementing the Company's lithium brine project are three rare metals pegmatite properties in Canada known as the Mavis, Raleigh, and Forgan projects, and the Avalonia project in Ireland, which encompasses an extensive 50km-long pegmatite belt. The Avalonia project is under option to strategic partner GFL, that currently owns 55% of the project. The Mavis and Raleigh projects are under option to strategic partner Pioneer Resources Limited (ASX:PIO) pursuant to which Pioneer can acquire up to a 51% interest in the projects.

The Mavis, Raleigh and Forgan projects together form the basis of the Company's newly created Upper Canada Lithium Pool designated to focus on acquiring numerous prospects with previously reported high concentrations of lithium in close proximity to existing infrastructure.

With the increasing demand for high tech rechargeable batteries used in vehicle propulsion technologies and portable electronics, lithium is paramount to tomorrow's "green-tech", sustainable economy. By positioning itself with solid strategic partners and acquiring high quality assets for the Energy rEVolution supply chain, ILC aims to be the partner of choice for investors in green-tech and to continue to build value for its shareholders.
