Integra Reports Final Results from 2015/2016 Infill Drill Program at Lamaque South Gold Project

Integra Gold Corp. is pleased to announce the final tranche of assay results from its 2015/2016 infill drill program on the No. 4 Plug Deposit situated at the Lamaque South Gold Project located in Val-d'Or, Québec.

"With all drill results from the No. 4 Plug Deposit exploration program in-hand, we are on track to update the resource estimate for this deposit by the end of 2016," commented Company President and CEO, Stephen de Jong. "The updated resource estimate will be followed by a series of trade-off studies to fully understand and assess the benefits of a bulk mining approach compared to the narrow vein mining methods currently being contemplated for other areas of the Lamaque Project."

Drill Results Continue to Show Potential for Bulk Mineable Resource

Infill drill holes disclosed today are located on the eastern side of the No. 4 Plug along a 75 m long east-west trend demonstrating lateral continuity of the gold mineralized vein clusters. The table below highlights selected results from this final tranche of the No. 4 Plug drilling program. The summary results are presented uncapped and, when applicable, with high grade values capped at 34.3 g/t Au (results are also available with high grade values capped at 20.0 g/t Au in the full assay table available at the link below).

As the gold distribution in the thick clusters of brittle, shallow-dipping tension veins has the tendency to portray a higher nugget effect relative to the high-angle C-type structures identified at the Triangle Deposit ("Triangle"), the selection of disclosed intervals is partially controlled by the visual occurrence of veins and the amount of pyrite in drill core along with grade distribution, providing a further layer of control for the spatial constraining of these thick vein clusters. The reported intervals are clearly identifiable visually in terms of vein densities present in drill core.

No. 4 Plug Next Steps

The Company intends to complete a new resource estimate on No. 4 Plug to be completed in H2 2016. Given the ample milling capacity and scalability of the Sigma Mill Complex (2,400 tons per day ("tpd"), expandable to 5,000 tpd), the Company believes that a combined scenario of selective high-grade mining at Triangle, in parallel with low-cost bulk-mining at No. 4 Plug situated 500 m north of Triangle, has the potential to ramp up production profiles beyond previous estimates.

Geological Setting at the No. 4 Plug

The No. 4 Plug is a sub-vertical dioritic/gabbroic intrusive, of similar shape to the Lamaque Mine Plug (located 2 kilometres ("km") to the northwest), which produced over 4.5 million gold ounces from surface to a depth of 1,100 m vertical. The No. 4 Plug intrusive is located 500 m north of Triangle and can be traced on surface for 200 m east-west by 150 m north-south, extending to a depth of over 1,000 m vertical. Gold mineralization is found within the intrusion hosted by quartz-carbonates-tourmaline shear veins associated with sub-vertical shear zones (similar to Triangle C-type structures) and flat lying quartz-carbonate-tourmaline veins that are present as dense vein clusters.

Interpretation of the reported gold bearing zones at No. 4 Plug indicate that these dense vein clusters can be tens of metres thick vertically, are geometrically stacked within the intrusion in the down-dip direction, and can also extend roughly 75 m to a maximum of 200 m laterally. The mineralized vein clusters are more abundant below a vertical depth of approximately 200 m, and are confined to the intrusion. The intrusive host and the vein clusters remain open at depth. The mineralogy and alteration assemblages associated with these vein clusters consist of carbonate, sericite, albite alteration, with varying intensity and distribution, being more pronounced near the high-angle shear zones. Where these sub-vertical shear zones cross-cut the intrusion, brittle and shallower dipping tension veins are more prominent.

The large gold bearing vein clusters have striking similarities to bulk zones mined historically at the Lamaque Mine, where historical records have recorded mining in panels in excess of 50 m wide. The style of mineralization at No. 4 Plug also resembles the nearby Agnico-Eagle Goldex Deposit, situated just west of Val-d'Or.
