FOR IMMEDIATE RELEASE TSX-V: ICG; OTCQX: ICGQF
Integra Gold Announces New Gold Discoveries with C-Type Structures Identified below 1,000 m at Triangle, C4 Zone Continues to Grow with Step-Out Drilling, 2016 Program Underway with 7 Drills in Operation
Press Release Highlights:
-
New discovery of sub-parallel C and C-Flat structures identified at depth structurally below the existing C6 zone, and below 1,000 metres ("m") depth, highlighting potential for further resource expansion outside of the current resource limits. One hole to date, TM-15-038, has tested the new targets with intercepts such as 15.68 grams per tonne gold ("g/t Au") over 5.8 m (4.94 m true thickness) and 8.14 g/t Au over 4.2 m (3.57 m true thickness)
-
Step-out drilling on the steeply dipping C4 mineralized structure at Triangle returned high grade mineralization including 11.61 g/t Au over 3.6 metres (3.39 m true thickness) and 9.94 g/t Au over 3.3 m (2.91 m true thickness)
-
Significant gold mineralization reported in the infill drilling of the C1 and C2 structures confirming the internal continuity of the zone with intercepts such as 16.06 g/t Au over 5.7 m (4.41 m true thickness) and 12.48 g/t Au over 4.3 m (3.48 m in true thickness)
VANCOUVER, BC: Integra Gold Corp. (TSX-V: ICG; OTCQX: ICGQF) ("Integra" or the "Company") is pleased to announce the first round of results from its fall 2015 / winter 2016 drill program on the Triangle deposit ("Triangle") on the Lamaque South Gold Project ("Lamaque") located in Val-d'Or, Québec.
"Results from the ongoing exploration program at Triangle continue to show substantial resource growth potential with the majority of assays reported today coming from holes drilled outside of the current resource envelope. The bulk of Triangle is largely shown to be hosted within a series of sub- parallel and stacked C structures, C1 to C6, displaying a certain degree of periodicity. We can confirm today that we have intersected yet another significant C-type structure hosting high gold grades, below a depth of 1,000 m vertical. In our view, this further enhances the notion that drilling has yet to identify the lateral and depth limits of the primary C-type structures which make up the bulk of the gold ounces in the Triangle deposit," commented Company President and CEO, Stephen de Jong. "The discovery of new C-type structures in the first hole designed to test below the lower resource boundary is especially encouraging and we look forward to building on this discovery with additional drilling in the months to come."
A total of 91,859 m in 206 holes was completed at Lamaque South in 2015, of which 59,753 m were conducted at Triangle. The drill program was re-initiated on January 4, 2016 with 7 drill rigs currently in
operation. The Company expects to drill approximately 90,000 m to 100,000 m in 2016 with the majority of drilling aimed at defining and expanding Triangle.
The results announced today are from 23 drill holes, including 5 abandoned holes and 5 wedges, for a total of 13,150 m. As of January 4, 2016, results are still pending from an additional 27 holes representing 19,000 m. Results from ongoing infill and extensional drilling at Triangle will be disclosed during the winter as they become available.

Triangle Gold Deposit Drill Results
Drilling conducted during the 2015 fall campaign at Triangle focused on widely spaced step-out and extensional drilling of the C4 structure and on infill drilling within selected areas of the C1 and C2 structures. Sheared host rock sequences and alteration assemblages associated with gold bearing veins were observed in most holes where the C structures have been interpreted, hosting high and low grade gold mineralization, and corresponding to extensions of these structures. The Company's geological model as well as results highlighted in this release, continue to demonstrate the predictive nature of this deposit, further highlighting the potential for additional gold bearing horizons to exist at depth and on- extension.
The table below highlights selected results from the extensional drilling conducted on the C4 structure (identified as C4 in the right most column) and of infill drilling of the C1 and C2 structures. Intersections marked with CX-XX (i.e. "C1-60") are from shallow dipping structures present between C structures and intersections marked with a C? are C-type gold bearing structures that require additional interpretation within the context of the existing geological model. These zones will be modelled as part of the next resource estimate planned for later this year.

Discovery of New C-Type Structures at Depth
Assay results from the first deep drill hole at Triangle are highly encouraging, as they demonstrate the potential for further deep gold discoveries. Deep drilling has confirmed both the presence of gold and the continuity of the mineralized system to a vertical depth of over 1,400 m.
During the 2015 fall campaign, one drill hole, TM-15-038, collared in the center of the deposit (on section 296375 m East) and south of the Triangle intrusive, was extended to a down hole depth of 2,016 m (approximately 1,700 m vertical). At its final depth, the drill hole had deviated, as expected, and traversed the Triangle intrusive host rock, terminating 300 m east of its starting collar. The objective of this drill hole was to test the potential for gold mineralization in the footwall and within the intrusive host rock to a depth of 1,800 m vertical. Mineralization at the adjacent Sigma Mine extended to 1,800 m and beyond.
This deep drill hole intersected multiple horizons of horizontal to steeply dipping quartz-tourmaline- pyrite veining, the typical host for gold mineralization at Triangle, with local C type shear zones identified to down hole depths of up to 1,695 m (approximately 1,425m vertical). Below down hole depths of 1,100 m, and within the intrusive host, horizontal flat lying quartz veining appears to dominate resembling the gold-bearing mineralization assemblages at the adjacent No. 4 Plug deposit.
Multiple anomalous gold mineralized intervals were encountered (23 in total), with reported grades varying from of 1.04 g/t to 15.58 g/t Au. Down hole thicknesses varied from 0.5 to 5.8 m throughout the
deeper part of the hole below a down hole depth of 1,100 m (i.e. structurally below the interpreted C6 structure - see link to complete assay table for details). These intercepts clearly demonstrate the potential for further gold bearing horizons to occur at considerable vertical depths, outside of the existing resource boundaries. The new gold bearing intervals reported show geological characteristics typical of the steeply dipping C type structures and are presented in the table below.

One additional drill hole, TM-15-074 located 100 m to the west of hole TM-15-038, is currently being extended to a similar depth to test the potential for lateral extensions of the newly identified C-type gold bearing structures.
2016 Drilling Program
Given an abundance of positive results and further continuity highlighted in step out drilling at Triangle, the 2016 program at Lamaque will move ahead with 90,000 m to 100,000 m of diamond drilling planned for the year. The bulk of the drill program will be completed during the winter months. Seven drill rigs are currently active on the project with the potential to add three more rigs in the weeks to come if weather permits. Integra's planned 2016 drilling is one of the largest drill programs being conducted in the Canadian mining industry at this time.
The ongoing winter drill program includes exploration, extensional drilling, and definition drilling on numerous key targets such as Triangle and the No. 4 Plug deposit. The program will also include exploration drilling of promising new targets outlined in 2015 in geophysical surveys, geological mapping, surface sampling and reconnaissance drilling conducted in 2015; additional information on these new targets will be provided by the Company in follow-up news releases this year.
Geological Background for Triangle - Structural Setting
Gold mineralization at the Triangle Zone, highlighted by an abundance of quartz-tourmaline veins with minor amounts of pyrite, is interpreted to be predominantly hosted within a series of parallel, steeply- dipping shear structures identified as "C" zones. These high angle structures strike east-west and dip south at angles varying from 55 to 75 degrees. The associated "C Flat" structures, which dip from 20 to 45 degrees to the south with an east-southeast strike, are interpreted as second order structural splays developing from the more steeply dipping "C" structures. A third order of horizontal veining has also been identified and likely developing from the C structures; although distribution of this type of veining is not well defined in part due to drill spacing. All structures are gold mineralized although the "C" zones are generally thicker, steeper dipping and more continuous. The Company's predictive model as it relates to the "C", "C Flat" structures, and horizontal veining will continue to evolve as more drill data becomes available.
