Expanded the Company's Memorandum of Understanding ("MOU") with Trout Unlimited to include

additional conservation efforts in proximity to Integra's operations in northern

George Salamis, President, CEO and Director of Integra commented:

"For years, Integra has used a

development strategy hinged upon the idea that strong environmental, social, and governance principles

would underpin how we design, permit, and build our future operations. Now, as the operators of Florida

Canyon, the measure lies in our ability to apply those principles as we deploy capital to support consistent

production at Florida Canyon, as well as drive the Company's broader growth strategy. Integra continues to

lead with transparency, with respect for local communities and Tribal Nations, and with the recognition that

exceptional environmental, social, and governance performance are fundamental drivers that create lasting

value for all stakeholders."

looking statements). Except for statements of historical fact,

certain information contained herein constitutes forward

looking statements which includes, but is not limited

to, statements with respect to: the Company's sustainability strategy, the economic and social benefits to be

derived from the Company's operations and its community programs; and the future financial or operating

"budget", "scheduled", "plans", "planned", "forecasts", "goals" and similar expressions.

Forward-looking statements are based on a number of factors and assumptions made by management and

considered reasonable at the time such statement was made. Assumptions and factors include: the

Company's ability to complete its planned exploration and development programs; the absence of adverse

conditions at the Projects; satisfying ongoing covenants under the Company's loan facilities; no unforeseen

operational delays; no material delays in obtaining necessary permits; results of independent engineer

technical reviews; the possibility of cost overruns and unanticipated costs and expenses; the price of gold

remaining at levels that continue to render the Projects economic, as applicable; the Company's ability to

continue raising necessary capital to finance operations; and the ability to realize on the mineral resource and

reserve estimates. Forward

looking statements necessarily involve known and unknown risks and

uncertainties, which may cause actual performance and financial results in future periods to differ materially

from any projections of future performance or result expressed or implied by such forward

looking

statements. These risks and uncertainties include, but are not limited to: general business, economic and

competitive uncertainties; the actual results of current and future exploration activities; conclusions of

economic evaluations; meeting various expected cost estimates; benefits of certain technology usage;

changes in project parameters and/or economic assessments as plans continue to be refined; future prices of

metals; possible variations of mineral grade or recovery rates; the risk that actual costs may exceed

estimated costs; geological, mining and exploration technical problems; failure of plant, equipment or

processes to operate as anticipated; accidents, labour disputes and other risks of the mining industry; delays

in obtaining governmental approvals or financing; risks related to local communities; the speculative nature of

mineral exploration and development (including the risks of obtaining necessary licenses, permits and

approvals from government authorities); title to properties; and other factors beyond the Company's control

and as well as those factors included herein and elsewhere in the Company's public disclosure. Although the

Company has attempted to identify important factors that could cause actual actions, events or results to

differ materially from those described in the forward looking statements, there may be other factors that

cause actions, events or results not to be as anticipated, estimated or intended. Readers are advised to
