Integra Gold Commissions AMEC to Conduct Environmental Baseline Study and Gap Analysis at Lamaque Gold Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 20, 2013) - Integra Gold Corp. (TSX VENTURE:ICG) ("Integra" or the "Company") is pleased to announce that it has entered into agreements with AMEC Environment & Infrastructure, a division of AMEC Americas Limited ("AMEC"), related to Gap Analysis and Environmental Baseline studies for its Lamaque Gold Project ("Lamaque") located in Val d'Or, Québec. The studies are an essential step towards the full evaluation and potential development of its main gold bearing zones at Lamaque (see map link below).

"AMEC is one of the world's leading engineering groups and has extensive experience in the region. The studies announced today are an integral part of the Company's bigger plan, to aggressively advance the Lamaque Gold Project towards development. We have made the decision to initiate these campaigns early on in the process as we are confident the pending resource estimate will warrant further advanced stage studies, beginning with a full Preliminary Economic Assessment (PEA)," commented Company President and CEO, Stephen de Jong. "Modelling of the primary gold bearing zones for the purpose of resource estimation continues and we remain on track to produce an updated estimate for the Lamaque Project in Q2, 2013. Once completed, the resource model will be combined with metallurgical and infrastructure studies to produce a PEA in late 2013. Further clarification on specific timing for the PEA will be provided as and when available."

Gap Analysis

The Gap Analysis will focus on identifying all potential applicable legal and permitting requirements, as well as linking those to required technical studies needing to be addressed in order that the project can advance smoothly and on schedule towards development. This study will aid in establishing a clear timeline and pathway towards underground exploration, development and production. It is expected that this study, which has direct links to the planned Preliminary Economic Assessment to be completed later on this year, will be completed within the next 2-3 months.

Environmental Baseline

The Environmental Baseline study will describe and define the base reference for numerous environmental, hydrological, wildlife, and socio-economic issues. Results of the study are to be used to apply for, and ultimately obtain, permits and environmental authorizations to initiate underground exploration as the Company continues towards potential production.

More specifically, data collection and studies will include climate, air quality, and noise surveys; geological, hydrogeological and hydrologic project definition; wildlife, flora and archeological status and potential issues; and social economic evaluation in terms of land use, economic impact, employment, and relation with the diverse stakeholders. Specific data collection and studies to be performed are an essential step towards completing a full Environmental Impact Study if and when required. The initial phase of the environmental baseline study will be completed in late 2013.

Ongoing Technical Studies

The Company has also initiated or completed technical studies and evaluations that will form an integral part of the planned 2013 Preliminary Economic Assessment (PEA) for the project. These studies include:

• an evaluation of available mills in the region in order to gather sufficient information for proper costing,
• structural evaluation of the main targets in the Southern Cluster (respectively the Triangle and Plug No. 4 targets) to improve the level of confidence in the mineral resource,
• metallurgical analysis that will provide key information on the potential gold recovery of known gold bearing zones,
• basic geotechnical studies in order to define global mining parameters regarding potential production.

Results of these studies will be released as they become available.

Lamaque Project and Company Profile

Integra's Lamaque Gold Project is located in the heart of the Val d'Or gold camp in the Province of Québec, Canada, approximately 550 km northwest of Montréal. The Lamaque Project's primary target, the South Cluster, is 4 km from the City of Val d'Or. Québec is rated one of the best mining jurisdictions in the world. Infrastructure, human resources and mining expertise are readily available.

The Company's primary objective is to continue to prove up additional resources while advancing the existing resource towards production. The project is split into two clusters, the North Cluster and the South Cluster, located approximate 1 km from each other.

South Cluster - No. 4 Plug and Triangle Zone

The South Cluster is the Company's top priority, and currently has a high grade gold resource of 444,962 inferred ounces grading 11.06 g/t Au in 1,263,046 tonnes, and 61,168 indicated ounces grading 13.51 g/t Au in 140,840 tonnes. Over 27,000 meters of drilling has been completed on the South Cluster since the last resource estimate. An updated resource estimate is expected to be completed in Q2, 2013.

North Cluster - Parallel Zone, Forestel Zone and No. 5 Plug

The North Cluster hosts an NI 43-101 resource estimate of 69,981 inferred ounces grading 2.03 g/t Au in 1,072,484 tonnes, and 101,794 indicated ounces grading 4.8 g/t Au in 659,959 tonnes. An additional 8,000 meters of drilling has been completed on the North Cluster since the last resource, which will also be included into the Q2, 2013 updated resource estimate.

Qualified Person

The Lamaque exploration project is under the direct supervision of Hervé Thiboutot, P.Eng. and Vice-President of the Company, a Qualified Person ("QP") as defined by National Instrument 43-101, Alain-Jean Beauregard, P.Geo., and Daniel Gaudreault, P.Eng., Geo., both of Géologica Inc., are independent QP as defined by National Instrument 43-101. The Company's QP has reviewed the technical content of this release.

Quality Assurance - Quality Control ("QA/QC")

Thorough QA/QC protocols are followed on the project including insertion of duplicate, blank and standard samples in all drill holes. The core samples are submitted directly to ALS Laboratory Group and Bourlamaque Labs in Val-d'Or for preparation and analysis. Analysis is conducted on 1 assay-ton aliquots. Analysis of Au is performed using a fire assay method with a gravimetric finish completed for samples exceeding 5 g/t Au, or a metallic sieve assay for samples containing visible gold. When available, the gravimetric or metallic sieve assay results were used for the reported composite intervals.
