Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Resources
The Company prepares its disclosure in accordance with the requirements of securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. Terms relating to mineral resources in this news release are defined in accordance with NI 43-101 under the guidelines set out in the Canadian Institute of Mining, Metallurgy, and Petroleum Definition Standards for Mineral Resources and Mineral Reserves 2014 (“CIM Definition Standards”).
The United States Securities and Exchange Commission (the “SEC”) has adopted amendments effective February 25, 2019 (the “SEC Modernization Rules”) to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the United States Securities Exchange Act of 1934. The SEC Modernization Rules have replaced SEC Industry Guide 7, which has been rescinded.
As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of “Measured mineral resources”, “Indicated Mineral Resources” and “Inferred Mineral Resources”, which are defined in substantially similar terms to the corresponding CIM Definition Standards. In addition, the SEC has amended its definitions of “Proven Mineral Reserves” and “Probable Mineral Reserves” to be substantially similar to the corresponding CIM Definition Standards.
United States investors are cautioned that while the foregoing terms are “substantially similar” to corresponding definitions under the CIM Definition Standards, there are differences in the definitions under the SEC Modernization Rules and the CIM Definition Standards. Accordingly, there is no assurance any Mineral Resources that the Company may report as “Measured Mineral Resources”, “Indicated Mineral Resources” and “Inferred Mineral Resources” under NI 43-101 would be the same had the Company prepared the resource estimates under the standards adopted under the SEC Modernization Rules.
United States investors are also cautioned that while the SEC will now recognize “Measured Mineral Resources”, “Indicated Mineral Resources” and “Inferred Mineral Resources”, investors should not assume that any part or all of the mineral deposits in these categories would ever be converted into a higher category of Mineral Resources or into Mineral Reserves. Mineralization described by these terms has a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. Accordingly, investors are cautioned not to assume that any “Measured Mineral Resources”, “Indicated Mineral Resources”, or “Inferred Mineral Resources” that the Company reports are or will be economically or legally mineable.
Further, “Inferred Mineral Resources” have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, United States investors are also cautioned not to assume that all or any part of the Inferred resources exist. In accordance with Canadian securities laws, estimates of “Inferred Mineral Resources” cannot form the basis of feasibility or other economic studies, except in limited circumstances where permitted under NI 43-101.
Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.
