FORWARD LOOKING STATEMENT
No stock exchange, securities commission or other regulatory authority has approved or disapproved the information contained on this presentation.
This presentation contains "forward-looking information" concerning Integra Gold Corp.’s (“Integra“ or the “Company”) future financial or operating
performance and other statements that express management's expectations or estimates of future developments, circumstances or results.
Generally, forward-looking information can be identified by the use of forward-looking terminology such as “seeks”, "believes", "anticipates", "plans",
“continues”, "budget", "scheduled", "estimates", "expects", "forecasts", "intends", “projects”, “predicts”, “proposes”, "potential", “targets” and
variations of such words and phrases, or by statements that certain actions, events or results "may", "will", "could", "would", “should” or "might" "be
taken", "occur" or "be achieved". Forward-looking statements included in this presentation include statements regarding potential mineralization and
mineral resources, the proposed mining scenario for the Lamaque Gold Project, including information with respect to the supporting infrastructure,
the potential life of mine, rates of employment and the effects of steps taken to mitigate local impacts and the expected completion dates of
exploration and drilling, exploration results, estimated and future exploration and administration expenditures, the completion of scoping studies,
preliminary economic assessment, pre-feasibility or feasibility studies, and future plans and objectives of Integra. While all forward-looking statements
involve various risks and uncertainties, these statements are based on certain assumptions that management of Integra believes are reasonable,
including that it will be able to obtain financing and on reasonable terms, that its current exploration and other objectives can be achieved, that its
exploration and other activities will proceed as expected, that its community and environmental impact procedures will work as anticipated, that
general business and economic conditions will not change in a material adverse manner, that Integra will not experience any material accident, labour
dispute or failure or shortage of equipment, and that all necessary government approvals for its planned exploration and potential development
activities will be obtained in a timely manner and on acceptable terms. There can be no assurance that the forward-looking statements will prove to
be accurate and actual results and future events could differ materially from those anticipated in such statements. Important factors that could cause
actual results to differ materially from the Integra’s expectations include, among others, the actual results of current exploration activities being
different than those anticipated by Integra, changes in project parameters as plans continue to be refined, changes in estimated mineral resources,
future prices of metals, increased costs of labor, equipment or materials, availability of equipment, failure of equipment to operate as anticipated,
accidents, effects of weather and other natural phenomena, risks related to community relations and activities of stakeholders, and delays in
obtaining governmental approvals or financing. Although Integra has attempted to identify important factors that could cause actual results to differ
materially, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such
statements will prove to be accurate as actual results and future events could differ materially from those anticipated in such statements. Accordingly,
readers should not place undue reliance on forward-looking statements. Integra does not intend, and expressly disclaims any intention or obligation
to, update or revise any forward-looking information or statements whether as a result of new information, future events or otherwise, except as
required by law.
Hervé Thiboutot, Eng., Senior Vice President, and Francois Chabot, Eng., Operation Manager, are the qualified person for the Company under National
Instrument 43-101, and have reviewed and approved all of the scientific and technical information contained in this presentation. The Company has
prepared NI 43-101-compliant technical reports for the Lamaque Property, respectively released on January 13 and February 10, 2015, which are
available on its website or at www.sedar.com. These technical reports include relevant information regarding the effective date and the assumptions,
parameters and methods of the mineral resource estimates on the Lamaque Property contained in this presentation and provide details on the
Preliminary Economic Evaluation. The mineral resource estimates stated in the presentation were prepared by independent consultants in accordance
with NI 43-101. A Qualified Person has not done sufficient work to classify the historical resources estimates contained in this presentation as current
mineral resources and the Company is not treating such historical estimates as current mineral resources. The historical mineral resources mentioned
in this presentation may not be conform to the NI 43-101 and should not be unduly accepted.

INTRODUCTION & HIGHLIGHTS
6 TERABYTES of digital mining and exploration data, comprising 75 years of mining history at
the Sigma and Lamaque Mines, was acquired in October 2014 by way of the Sigma/Lamaque
Mines and Mill Acquisition.
5 YEARS & $5M spent by the previous owners on the compilation of this data, including over
30,000 drill holes, hundreds of thousands of gold assays, hundreds of kilometers of underground
workings, mining statistics, geological sections, level plans, and photos. This data has never been
fully analyzed or used for exploration targeting until now.
“PROOF-OF-CONCEPT” data-points and intercepts have been uncovered by Integra,
highlighting numerous new areas and extensions of mineralization at Sigma and Lamaque that
remain untested.
LAMAQUE DEEP
the down-dip extension of the Lamaque Mine, below 1,100 meters vertical, is
the most obvious target. The Lamaque Mine was once Québec’s largest gold mining operation
between 1955 to 1985 and was host to one of the highest “ounce-per-vertical-meter” gold
deposits (4,000 oz Au / meter) in the Abitibi Greenstone Belt, one of the richest gold belts in the
world.

LAMAQUE DEEP TARGET CONCEPT SUMMARY
SIGMA-LAMAQUE
•
World Class deposits
LAMAQUE DEEP
•
Target area contains all the gold bearing structures and favorable host rocks from both mines:
• “Plugs” as a favorable intrusive host rock, dipping northeast towards the Sigma mine
• Similar quartz-tourmaline-pyrite veining and related shear zones
• The projection of mineralized shear zones from Sigma are dipping southward towards the
Lamaque intrusive plugs
CONCLUSION
•
•
•
Highlights an unexplored target area below 1,100 meters vertical at Lamaque Mine
Area subjected to extremely limited past drilling within a largely unexplored volume of rock
• Target is a minimum of 730m vertical by 600m North-South by 700m East-West
• Lamaque and Sigma mines unexplored below 1,100m and 1,830m vertical, respectively
• Significant gold grades reported in historic drill holes which were not drilled at optimal
orientations
• Recovered gold bearing intercepts give strong evidence of continuity at depth
Sigma and Lamaque gold bearing structures likely to extend beyond 1,830m vertical, at depth
and laterally
