variations (including negative variations) of such words and phrases, or state that certain actions, events

or results “may”, “could”, “would”, “might” or “will” be taken, occur or be achieved) are not statements

reflect our current judgment regarding the direction of our business. Management believes that these

assumptions are reasonable. Forward -looking information involves known and unknown risks,

uncertainties and other factors which may cause the actual results, performance, or achievements of the

Company to be materially different from any future results, performance or achievements expressed or

implied by the forward- looking information. Such factors include, among others: risks related to the

speculative nature of the Company’s business; the Company’s formative stage of development; the

Company’s financial position; possible variations in mineralization, grade or recovery rates; actual results

of current exploration activities; actual results of reclamation activities; conclusions of future economic

evaluations; business integration risks; fluctuations in general macroeconomic conditions; fluctuations in

securities markets; fluctuations in spot and forward prices of gold, silver, base metals or certain other

commodities; fluctuations in currency markets (such as the Canadian dollar to United States dollar

relations; relationships with and claims by local communities and indigenous populations; availability of

increasing costs associated with mining inputs and labour; the speculative nature of mineral exploration

and deve lopment (including the risks of obtaining necessary licenses, permits and approvals from

government authorities); and title to properties. Although the forward -looking statements contained in

this news release are based upon what management of Integra beli eves, or believed at the time, to be

reasonable assumptions, Integra cannot assure its shareholders that actual results will be consistent with

such forward-looking statements, as there may be other factors that cause results not to be anticipated,

estimated, or intended.

Forward-looking statements contained herein are made as of the date of this news release and the

Company disclaims any obligation to update any forward-looking statements, whether as a result of new

information, future events or results, except as may be required by applicable securities laws. There can
