Cautionary Note for U.S. Investors Concerning Mineral Resources and Reserves

National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”) is a rule of the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Technical disclosure contained in this news release has been prepared in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum Classification System. These standards differ from the requirements of the U.S. Securities and Exchange Commission (“SEC”) and resource information contained in this press release may not be comparable to similar information disclosed by domestic United States companies subject to the SEC’s reporting and disclosure requirements.

Max Baker Ph.D. (F.AusIMM), Integra’s Chief Geologist, a “Qualified Person” (“QP”) as defined in NI 43-101. The scientific and technical information regarding the Company’s Wildcat and Mountain View properties contained on this website has been reviewed and approved by Raphael Dutaut, Ph.D., P.Geo., Integra’s Vice President, Exploration, a QP as defined in NI 43-101.

Cautionary Note Regarding Non-GAAP Financial Measures

Alternative performance measures in this document such as “cash cost”, “AISC” “after-tax cash flow” are furnished to provide additional information. These non-GAAP performance measures are included on this website because these statistics are used as key performance measures that management uses to monitor and assess performance of the DeLamar Project, and to plan and assess the overall effectiveness and efficiency of mining operations. These performance measures do not have a standard meaning within International Financial Reporting Standards (“IFRS”) and, therefore, amounts presented may not be comparable to similar data presented by other mining companies. These performance measures should not be considered in isolation as a substitute for measures of performance in accordance with IFRS. All references to “$” on this website are to U.S. dollars unless otherwise stated.
