Integra Gold Intersects 19.81 g/t gold over 19.0 m (uncapped) at Triangle and Commences a 2,500 m Drill Program on First Gold Rush Challenge Target
Press Release Highlights:
-
Today's results include 19.81 g/t gold ("Au") over 19.0 metres ("m") (17.5 m true width, 8.31 g/t Au when capped at 34.3 g/t Au) from the C4 structure infill drill program which represents the widest ever gold bearing intercept reported at the Triangle Deposit
-
Results announced today also include 18.58 g/t Au over 9.7 m and 27.10 g/t Au over 5.95 m (respectively 4.76 m and 8.18 m in true width, and 19.55 g/t Au and 15.04 g/t Au when capped at 34.3 g/t Au) from the near surface C2 structure infill drill program
-
Drill results at C2 continue to return both grade and widths materially higher and thicker than the previously reported zone averages of 3.22 m in thickness and 7.50 g/t Au in grade (at a 5.0 g/t Au cut off) from the November 2015 resource estimate
-
325 m of lateral development completed on exploration decline as of October 11, 2016, current position approximately 300 m away from the western limit of the C1 and C2 structures
-
6 drill rigs are currently active on the Lamaque Gold Project, including four at the Triangle deposit, one testing the Lamaque Deep target (current drill hole depth of 1,596 m), and one recently added to test one of the priority Gold Rush Challenge targets
VANCOUVER, BC: Integra Gold Corp. (TSX-V: ICG; OTCQX: ICGQF), ("Integra" or the "Company") is pleased to announce additional assay results from its 2016 drill program on the Triangle Deposit ("Triangle") situated on the Lamaque Gold Project ("Lamaque") in Val-d'Or, Québec. Results continue to support gold zone continuity with infill drilling generally intersecting significantly higher grades and wider intervals than anticipated. The results announced today are from 14,550 m of drilling conducted in 2016 and assays are currently pending from an additional 32,900 m (109 drill holes) of diamond drilling at Triangle.
"As both infill and expansion drilling successfully continues at Triangle, we are also pleased to report the mobilization of an additional drill rig to test one of the high priority targets produced from the Company's exploration crowd sourced competition, the Integra Gold Rush Challenge," commented Company President and CEO, Stephen de Jong. "The Gold Rush Challenge involved 1,400 entrants from over 90 countries and resulted in Integra receiving over 3,000 pages of exploration ideas and targets in and around its existing operations. The top twenty submissions have since been compiled and reviewed by company consultants into one summary report and we are excited to start drill testing the first target."

n/a - no zone assigned yet
-
Downhole thickness; true width varies depending on drill hole dip; most drill holes are aimed at intersecting the vein structures close to perpendicular therefore true widths are close to downhole widths (approximately 85% conversion ratio); true widths of C structure intercepts are presented on longitudinal sections.
-
For known mineralized zones, intervals are based on geological observations, i.e. on the amount of quartz veining, a 1.00 g/t gold cut-off for compositing in intervals outside mineralized zones; individual composites are presented uncap and capped (when applicable) with individual values capped at 34.3 g/t Au; no minimum thicknesses considered.

Infill Drilling in the C2 Structure Continues to Highlight Strong Internal Continuity and Resource Upside with Higher Grade and Wider Average Thickness
"It is encouraging to witness infill drilling delivering wider and higher grade intervals than anticipated at C2, in addition to reporting the widest ever interval at Triangle on the C4," commented Company Senior Vice President, Hervé Thiboutot. "A number of the wide, high grade zones recently identified in drilling occur in the near surface portion of the C2 structure, an area of the deposit we will soon have access to via the exploration ramp that is currently under development."
The C1 and C2 structures host the majority of the gold mineralization in the upper portion of Triangle and are the focus of an extensive infill drill program conducted at 25 m centers. The objective of this program is to continue to define the internal continuity of gold mineralization while, at the same time, provide additional information to guide the underground exploration ramp that was initiated in July 2016.
Results announced today are some of the best ever reported from the C2 structure, in particular drill holes TM-16-124 and TM-16-128A which both intersected significant high grade gold mineralization:
-
27.10 g/t Au over 5.95m (19.55 g/t Au when capped at 34.3 g/t Au, 4.76 true width) and;
-
18.58 g/t Au over 9.70m (15.04 g/t Au when capped at 34.3 g/t Au, 8.18 m true width).
Recent intercepts from the C2 structure are consistently wider and higher grade than the November 2015 resource estimate averages for that zone. At a 5 g/t cutoff the average true thickness of the C2 structure from the November 2015 resource was 3.22 m while the average grade was 7.50 g/t Au. While not necessarily representing the entire C2 structure, recently reported infill intercepts (including those disclosed today) highlight the potential for the structure to increase in thickness and average grade, and for the resource to expand.
Other significant intervals reported today from the C2 structure include (uncapped, downhole thicknesses):
15.23 g/t Au over 5.0m (TM-16-133AW01M01)
10.21 g/t Au over 4.7m (TM-16-139B)
15.51 g/t Au over 5.0m (TM-16-154)
12.42 g/t Au over 3.9m (TM-16-161M01)
18.32 g/t Au over 2.4m (TM-16-169AM01)
As illustrated in the longitudinal sections for C2 (see link below), results from numerous intercepts in that structure are still pending. Note that the true thickness of intervals are indicated on all longitudinal sections and will differ from downhole lengths reported in the drill assay table.

Triangle: Widest Intervals Ever Reported from Infill Drilling at C4
Infill drilling at C4 continues to successfully demonstrate mineralization continuity at Triangle. The results announced today include the widest interval ever reported at Triangle: 19.0 m of 19.81 g/t Au (8.12 g/t Au when individual assay intervals are capped at 34.3 g/t, 17.5 m true width). This specific intersection is from the upper western portion of the C4 structure, situated in an area classified as part of the inferred resource on the deposit. This intercept is of particular importance since it occurred in volcanic units 150 m west of the Triangle dioritic plug, demonstrating once more that mineralization at Triangle can extend hundreds of metres from the intrusive into the country rock, enhancing its resource potential.
The reported 19.0 m interval consists of a zone of tension veins within an intensely altered volcanic unit from 583.5 m to 588.3 m downhole. This is followed by the C4 sheared vein structure itself from 588.3 m to 595.9 m and finally, from 595.9 m to 602.5 m, by additional tension veining and the C4-20 C-flat structure also hosted within intensely altered volcanic rocks. Intersections of the C and C-Flat structures were known from previous drilling interpretation to have the potential to highlight wider areas of mineralization whose potential for bulk mining will need to be assessed in future studies. Unique to this drill intersection is the fact that the identification of the two main structures is also accompanied with numerous gold bearing semi-horizontal tension veins and veinlets within the wider altered rock sequence.
Please follow the following link to the core photos, highlighting the above description. http://www.integragold.com/i/pdf/Core_Photos_Oct_2016.pdf
The intersection of C and C-Flat structures is another example of the similarity between Triangle and the historic Lamaque Mine located 3 km to the northwest which produced 4.5 million ounces during its +50 years mine life. The historic Lamaque Mine had areas that included all three types of vein structures (C, C-Flat and horizontal tension veins), similar to those identified at Triangle, which were historically mined using bulk mining methods. The combination of these zones, when present at the historic Lamaque Mine, provided more tonnage to the mine plan and drastically increased the number of ounces per vertical metre produced from the Lamaque Main Plug.
The results disclosed today continue to demonstrate the potential for the C4 structure to contribute to potential resource base improvements in deeper sections of Triangle (below 450 m vertical). To date, C4 is the largest and most continuous of the high-angle C-type structures at Triangle.
As illustrated in the attached vertical longitudinal section of the C4 structure (see link below), additional results are pending from multiple infill and extensional drill holes at various depths ranging from 325 to 825 m vertical.
