Update on exploration activities

• Targets generated as a result of exhaustive compilation work, complimented by the Gold Rush Challenge, of all mining and exploration data comprising more than 75 years of mining history from its Sigma/Lamaque Mine and Mill acquisition.
• “Lamaque Deep” is the most obvious untested gold target in proximity to the Sigma/Lamaque Mines, and corresponds to the depth intersection of the Lamaque Mine Main Plug (historic production of more than 4.5 million ounces) and the Sigma Mine gold mineralized shear veins structures (historical production of 4.5 million ounces).
• The Lamaque Mine was Québec’s largest gold mining operation from 1955 to 1985 and was host to one of the highest “ounce-per-vertical-meter” gold mines (~4,000 ounces/m) in the Abitibi Greenstone Belt.
• The Sigma and Lamaque mines, separated by only 500 m, share the same lithological and structural mineralization controls; the Sigma Mine was in production from surface to a depth of 1,850 meters (“m”) and the Lamaque Mine produced from surface to a depth of 1,100m.
• The Lamaque Deep target is being tested by one master pilot hole forming the basis to originate multiple secondary wedged off-set holes at various depth intervals; drill program designed to fully test the intersecting gold bearing geometries between the Sigma and Lamaque deposits and the depth extension of the Lamaque Main Plug.
• Integra Gold is hosting the First Annual Fête d’Éte today, August 3rd 2016, in Val-d’Or, Quebec. The Fête d’Éte is a community celebration where members of the financial community who have supported the Company and members of the local population can spend time with Integra management and local employees to learn more about the project and the Company’s plan for the future. Follow Integra Gold on Facebook and Twitter, and join the Company for a Facebook Live Q&A with CEO Stephen de Jong and Executive Chairman, George Salamis Wednesday August 3rd, at 3:30pm EST.

Integra Gold Corp. (TSX VENTURE: ICG) (OTCQX: ICGQF) (“Integra” or the “Company”) is pleased to announce the initiation of a 2,000m pilot hole on its Lamaque Deep target, situated on the Lamaque Gold Project (“Lamaque”) located in Val-d’Or, Québec. Once the pilot hole has been completed (est. completion Q4 2016) the target will be tested with a minimum of 15 wedged holes originating from the pilot hole at various intervals. The Company is anticipating the entire program including wedges will total 10,000m of drilling.
“We have been looking forward to drill testing this target ever since we took ownership of the ground and historic records as part of our mill acquisition in October of 2014. The target area, defined by a box that’s roughly 1 km by 1 km starting at a depth of 1,000 m below surface, represents one of the most exciting drill targets in our exploration program today. For almost 50 years these two mines, less than 500m from one another, were operated by two major company owners, Placer Dome and Teck, who cumulatively produced over 9 million ounce of gold. Over the history of these two deposits, the respective mine management groups were of the view that both gold deposits were related, but could not test this target due to the ownership structure.”
Lamaque Deep Exploration Target Concept and Parameters
In 2015, following the acquisition of the Sigma/Lamaque Mine and Mill complex immediately adjacent to its Lamaque South project, Integra commissioned the services of several industry experts to consolidate, validate and evaluate the historic digital data from the two past producing mines, amounting to 6 terabytes in size. This compilation was used to define potential geometric extensions of the Lamaque Main Plug intrusive which hosted over 85% of the 4.5 million ounces of gold produced at the Lamaque Mine over a 50 year period. The depth extension of the Main Plug, with targeting further refined by the Company’s in-house knowledge together with information from this year’s Gold Rush Challenge submissions, will now be tested by first drilling a master pilot hole located in the structural footwall of the mineralized intrusive plug. The completed master pilot hole will then form the origin for multiple (minimum of 15) wedged off-set holes at various intervals below 1,000m vertical depth, designed to test for gold mineralized extensions below Lamaque.
The Lamaque and Sigma Mines are located 500m from one another and are being interpreted by the Company’s exploration and geological team as two different setting of a singular gold deposit and mineralized system. These mines each produced more than 4.5 million ounces of gold respectively; however, the Sigma Mine reached a vertical depth over 700m deeper than Lamaque. The Lamaque Mine ceased operations in 1985 due to falling commodity prices, labor unrest, and development limitations due to insufficient infrastructure; the mine was not closed as a result of the mineralized system being exhausted at depth. Integra’s compilations of mine workings from the lowest levels of mining at Lamaque conducted by Teck, showed excellent gold grades often in excess of 15 g/t and vein continuity over hundreds of meters; hence the view that the mine was not shut down due to lack of gold or pinching veins at depth. The Lamaque Mine was the largest gold producer in Québec over a 30 year period, from 1955 until its closure in 1985. The historic data compiled by the Company provides compelling evidence that down-dip extensions of the gold-bearing system of the Lamaque Mine Main Plug, where it intersects shear structures dipping south from the Sigma Mine side of the original property boundary, continues at depth.
As part of the compilation process, a 3D model of the main mineralized structures and geology has been produced and clearly demonstrates the potential for significant gold resource extensions at depth. Integra’s technical team, supported by external experts, has identified several instances in the database showing documented proof that gold mineralization, both low and high grade over wide zones in excess of 90m in thickness, exists in conjunction with the depth extensions of the Lamaque Mine itself. The Company’s technical team has concluded that the historic results clearly demonstrate proof-of-concept that gold mineralization continuity exists at depth below the two mines and warrant further drill testing.
Geological compilation work has also demonstrated that the Lamaque Deep target area hosts most of the gold bearing structures and favorable host rocks from both mines providing optimal gold discovery conditions: pipe-like intrusive dioritic “plugs,” a favorable host rock which dips northeast towards the Sigma mine, and similar quartz-tourmaline-pyrite gold bearing vertical and “flat” veining arrays related to shear zones. The downward projection of most of the gold mineralized shear zones from the Sigma Mine are also dipping southward towards the extension of the Lamaque Main Plug itself, providing an ideal exploration target area below 1,100m depth at the Lamaque Mine. Compilation work shows that this target zone with its optimal set of host conditions was previously intersected in a very limited historic drill-campaign conducted in 1997 by previous operators. Though this limited drilling was not performed at optimal orientations due to its location and limited access, it intersected significant widths of gold mineralization. Follow-up exploration and development was never completed due to financial restraints the company was facing at the time. These limited gold intercepts with the optimal target horizon provided strong evidence of continuity at depth. Aggressive drill campaigns on the Triangle and other deposits over the past 4 years, together with information gathered during the Company’s recent Gold Rush Challenge, were also of tremendous value in identifying the ideal target conditions related to the Lamaque Deep concept. The structural and lithological similarities between Triangle/No. 4 Plug and Sigma/Lamaque cannot be ignored, nor can the valuable lessons learned from the Gold Rush Challenge. Both have been pivotal in the structuring of this Lamaque Deep drill campaign.
A summary of some of the historical drill intercepts that have identified extensions of mineralization below the Lamaque Main Plug, representing an extremely limited amount of historic drilling within a large volume of rock, in the down-dip direction and up to 500m away from known past mining activity, are listed below:
