CANADIAN INTERNATIONAL MINERALS INC. ANNOUNCES INFERRED RESOURCE ESTIMATE OF 2,049,000 TONNES OF LITHIUM CARBONATE EQUIVALENT ON LEDUC LITHIUM BRINE PROJECT

Canadian International Minerals Inc. has filed a technical report detailing an inferred resource estimate for the company's Leduc lithium brine project, in accordance with National Instrument 43-101. The independent technical report, titled "Sturgeon Lake Li-K-B-Br-Ca-Mg-Na Oil Field Brine Inferred Mineral Resource, Leduc Property, West-Central Alberta," dated Jan. 22, 2016, was prepared for the company by Roy Eccles, MSc, PGeol, and Michael Dufresne, MSc, PGeol, of APEX Geoscience Ltd., based in Edmonton, Alta. Both Mr. Eccles and Mr. Dufresne are qualified persons within the meaning of National Instrument 43-101 and are independent of the company. The technical report is available under the company's profile on SEDAR and is available on the company's website.

The technical report outlines an inferred resource estimate on the Leduc lithium project of 385,000 tonnes of elemental lithium (Li) or 2,049,000 tonnes of lithium carbonate equivalent (Li2CO3).

To define a mineral resource estimate for Li, K, B, Br, Ca, Mg and Na in the Leduc formation aquifer system of CIN's Leduc property, APEX used the total in-place formation water volume of 5.7 billion cubic metres, average mineral grades that were derived from 2011 formation water sampling and conservatively assumed a grade weight (density) of 1,000 kilograms per cubic metre of brine. The mineral resource estimate has been classified as inferred according to the Canadian Institute of Mining, Metallurgy and Petroleum definition standards and is based on geological confidence, data quality and grade continuity.

The Sturgeon Lake Li-K-B-Br-Ca-Mg-Na oil field brine inferred mineral resource estimate can be summarized, in elemental and oxide form, as follows:

  • At an average grade of 67.5 milligrams per litre and assuming 5.7 billion cubic metres of water, the inferred resource estimate for lithium is 385,000 tonnes (2,049,000 tonnes of Li2CO3).
  • At an average grade of 4,641.3 milligrams per litre and assuming 5.7 billion cubic metres of water, the inferred resource estimate for potassium is 26,455,000 tonnes (31,868,000 tonnes of K2O).
  • At an average grade of 114.0 milligrams per litre and assuming 5.7 billion cubic metres of water, the inferred resource estimate for boron is 650,000 tonnes (2,093,000 tonnes of B2O3).

Mineral resources that are not mineral reserves do not have demonstrated economic viability. There is no guarantee that Li and associated elements (K, B) described above will be economically extractable from the formation waters with current technology. In addition, the quality and grade of the reported inferred resource in this estimation are uncertain in nature, there has been insufficient exploration to define these inferred resources as an indicated or measured mineral resource, and it is uncertain if further exploration will result in upgrading them to an indicated or measured resource category.

The lithium-bearing Leduc formation brine is situated within the Sturgeon Lake oil field, which represents a mature petroleum field. That is, in the early history of this oil field, most wells started out with high oil-to-water extraction ratios. However, at present, most of the wells produce excessive amounts of formation water in comparison with petroleum. The formation water is treated as a waste product during the petroleum extraction process, after which the brine is injected back down into the subsurface. The level of extractability of the Li and other elements from the waste formation water is unclear and will require new technologies (some of which are being introduced and tested in Nevada brines) that may or may not extract all or a portion of these elements.

APEX commissioned Hydrogeological Consultants Ltd. of Edmonton, Alta., to conduct a hydrogeological study to assess the total brine in place and other associated hydrogeological aspects of the Leduc formation aquifer underlying the Leduc property area (such as available drawdown). Mr. Eccles oversaw data contribution to, and calculations during, the aquifer characterization study and has deemed that the subsequent report and information, to the best of his knowledge, are valid contributions to this technical report and therefore takes ownership of the ideas and values as they pertain to the current technical report.

The formation water sampling and chemical analysis, which were overseen by APEX, were conducted by Maxxam Environmental of Edmonton, Alta. Maxxam is an accredited laboratory with the Standards Council of Canada (laboratory No. 160; valid to March 6, 2019) and with the Canadian Association for Laboratory Accreditation (membership No. 2996; valid to June 8, 2017), where Maxxam's standard conforms to requirements of ISO.IEC 17025.

Mr. Eccles is a professional geologist with the Association of Professional Engineers and Geoscientists of Alberta and has worked as a geologist for more than 25 years since his graduation from university. He has been involved in all aspects of mineral exploration and mineral resource estimations for metallic and industrial mineral projects and deposits in North America. He has conducted compilations and advanced geological studies on the Swan Hills formation waters with the Alberta Geological Survey to better document northwestern Alberta formation water and to determine the origin of the unique lithium-enriched formation water in this area (Eccles and Jean, 2010; Eccles and Berhane, 2011).

Mr. Dufresne is a professional geologist with the Association of Professional Engineers and Geoscientists of Alberta and has worked as a geologist for more than 25 years since his graduation from university. He has conducted fieldwork on the property and surrounding areas, as well as supervised a number of exploration programs for a variety of commodities across the Swan Hills region.

The report is a compilation of publicly available information. The information and data used in this technical report are based on formation water well sampling data that were completed in 2011 and on compiled publicly available geological and geochemical data for CIN's Leduc property. The data compilation, original oil field formation water sampling, sample chain of custody, analytical direction and management, data validation, and interpretation were supervised and conducted by APEX, under the direct supervision of Mr. Eccles and Mr. Dufresne.
