VANCOUVER, BC: Integra Gold Corp. (TSX-V: ICG; OTCQX: ICGQF), ("Integra" or the "Company") is pleased to announce a first round of assay results from its late fall 2015 and 2016 infill drill program on the No. 4 Plug Deposit situated at the Lamaque South Gold Project ("Lamaque") located in Val-d'Or, Québec.
"We believe now is the right time to evolve our growth strategy and expand our exploration efforts. As we continue to prove up Triangle we are finalizing an exploration plan that will focus on other targets on the property that we feel have the potential to increase both the feed to the mill and the total annual production profile at Lamaque," commented Company President and CEO, Stephen de Jong. "The continued success at Triangle and our latest drill results from No. 4 Plug confirm our beliefs that multiple deposits across our property can add substantial value to Integra."

No. 4 Plug Showing Potential for Bulk Mining, C-Structures Present along with Abundance of Flat-Lying Tension Veins
"Gold mineralization at No. 4 Plug, located 500 m north of Triangle is, in part, hosted within a series of steeply-dipping stacked shear zones similar to C-type structures found at Triangle," commented Company Senior Vice-President, Hervé Thiboutot. "What makes these zones different is the abundance of flat lying tension veins which form large clusters of veins that are potentially amenable to bulk mining methods. These large gold bearing vein clusters have striking similarities to bulk zones mined historically at the Lamaque Mine and present close resemblance to the nearby Agnico-Eagle Goldex Deposit which is found in similar hosts rocks and vein arrays."
The results disclosed today are from the Company's late 2015 and 2016 infill drill program completed at No. 4 Plug in areas that required 25 m drill spacing for the reinterpreted geological model and subsequent resource estimate. These results are significant given that high grade gold mineralization is still being identified within high-angle structures, similar to those found within Triangle, while wider zones forming vein clusters are now being recognized and are enhancing the Company's modelling and resource estimation approach at No. 4 Plug. These enhancements are likely to further refine and enhance our approach with respect to future mining optimization on the deposit. As the gold distribution in the thicker sequences of brittle, shallow dipping tension veins have the tendency to portray a higher nugget effect relative to the high angle C-type structures, the selection of disclosed intervals is largely controlled by the visual occurrence of veins in drill core logging rather than strictly on gold grade, providing a further layer of control for the spatial constraining of these thick vein clusters.
The table below highlights the selected results from this first tranche of the 2015 and 2016 No. 4 Plug infill drill program. The summary results are presented uncapped and, when applicable, with high grade individual values capped at 34.3 grams per tonne gold ("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).

-
Down-hole thickness; true width varies depending on drill hole dip and on general orientation of the vein clusters; most 2015 drill holes were aimed at intersecting the generally flat lying vein clusters close to perpendicular; therefore true widths are close to down-hole widths.
-
Minimum 1 g/t cut off over 10 m interval, allowing up to 5 m of below cut off material internally - individual assays cut to 34.3 g/t and 20.0 g/t Au when applicable - no minimum thickness considered.

Geological Setting at No. 4 Plug
No. 4 Plug is a sub-vertical dioritic/gabbroic intrusive, similar to the Lamaque Mine Plug, located 2 kilometres to the northwest, which produced over 3.7 M gold ounces from surface to a depth of 1,100 m vertical. The No. 4 Plug intrusive is located 500 m from 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 within the intrusive host is hosted within quartz-carbonates-tourmaline veins within sub-vertical shear zones (similar to Triangle C-type structures) in addition to flat lying quartz-carbonate-tourmaline veins that are present as dense vein clusters. The No. 4 Plug also presents similarities to the nearby Agnico- Eagle Goldex Mine host rocks and vein arrays, located 10 km to the west of the Lamaque property. For comparison purposes, with data taken from disclosed public information (see Agnico-Eagle's website), the average grade of the Goldex deposit is 1.8 g/t Au with a cut off set at 0.9 g/t Au; the direct mining costs at Goldex are at $34 per tonne, with ore mined using bulk mining methods.
Preliminary interpretation of the intersected gold bearing zones at No. 4 Plug indicates that these dense vein clusters can be tens of metres thick vertically, are geometrically staked within the intrusive in the
down-dip direction, and can also extend roughly 150 m to 200 m laterally. The mineralized vein clusters appear to be more abundant below a vertical depth of 200 m, remaining confined to within the intrusive plug. The intrusive host and the vein clusters remain open at depth as indicated by previously disclosed results from the drilling completed in 2012 (see summary tables and a link to full tables below). Similar vein mineralogy and alteration assemblages consisting of carbonate, sericite, albite alteration is associated with these dense veins clusters but vary in intensity and distribution, being more pronounced when cross-cut by high-angle shear zones. Where these sub-vertical shear zones cross-cut the intrusive, brittle and shallower dipping tension veins appear to be more dominant.
In consideration of this new evidence regarding the distribution and controls of gold mineralisation at No. 4 Plug, a complete geological re-modelling program was initiated in early 2016 and is approaching completion. Once the new geological model is available an updated resource estimate will be completed and disclosed later in 2016.
Historic mining in the late 1960s was performed by Teck in the upper part of No. 4 Plug (above 200 m vertical). New 3D modelling of historic stoping indicates both high angle veins and vein clusters were mined, which provides additional certainty in the modeling at No. 4 Plug. Approximately 50,000 ozs of gold were recovered by Teck from No. 4 Plug.
Results from Previous Drilling
In light of the new geological understanding at No. 4 Plug, results from 21 holes drilled on No. 4 Plug during the 2012 drill campaign (20,500 m) were also re-compiled, re-evaluated, and re-interpreted. The table below highlights selected results from the 2012 No. 4 Plug drill program in the context of the new vein cluster interpretation. Due to the abundance of intervals reported from 2012 drilling, only a few intervals are presented below. Please follow the link below to view the complete 2012 assays. Results are presented uncapped and, when applicable, with high grade individual 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). In general, these results show that capping of higher grade values has a limited effect on most of the reported mineralized intervals which tend to confirm the widespread nature of gold mineralisation at No. 4 Plug.
