Integra Gold Corp. is pleased to announce additional assay results from its Fall 2015/Winter 2016 drill program on the Triangle deposit situated on the Lamaque South Gold Project in Val-d'Or, Québec.
In addition to an extensive surface drill program the Company is in the final stages of preparing for its first ever underground exploration program at Triangle with the initial blasting scheduled to commence later this month.
"Today's results continue to show both strong mineralization continuity and exciting resource growth potential within the C-type structures at the Triangle deposit. Step out hole TM-15-018 announced today in addition to the other recent drill results have opened up the western portion of the C4 structure. The C4 structure already accounts for approximately 40% of the Triangle deposit's resource," commented Company President and CEO, Stephen de Jong. "In addition to this we are continuing to see both the C1 and C2 structures grow which is encouraging as they will make up the first phase of any contemplated mining scenario at Triangle."

C4 Drilling Continues to Expand Mineralization
Results disclosed today include intercepts within C4, the largest, high-angle structure at Triangle, which continue to demonstrate the potential for growth with an interval grading 33.55 grams per tonne gold ("g/t Au") over 3.2 m (15.91g/t Au when cap at 34.3 g/t Au, downhole width) on the western edge of that structure at a depth of 605 m vertical.
As illustrated in the attached vertical longitudinal section of the C4 structure (see link below), additional results are pending from a minimum of 6 drill holes testing the western extension of that structure, 100 to 150 m west from previous drilling. Visual observations of those holes indicate that the structure is still open to the west with varying amounts of mineralization.

Please note, square intercepts on the long section represent drill holes included in the November 2015 resource estimate while circular intercepts represent drill holes completed after the data base cut-off (July 30, 2015) for the November 2015 resource estimate. All results on long sections are true width and may differ slightly in length when compared to the drill table below.
Continuity and Resource Growth Potential for the C1 and C2 Structures
The C1 and C2 structures host the majority of the gold mineralization for the upper portion of Triangle. Today's results are significant as high grade gold mineralization continues to be identified at relatively shallow depths (above 475 m vertical). These results both confirm the continuity of these upper zones as well as show the potential for near-surface lateral resource expansion along strike.
Intercepts disclosed today include the following significant results in both the C1 and C2 structures (downhole widths, intercepts uncapped - refer to table below for capped results):
In the C1 structure:
- 10.43 g/t Au over 3.0 m in hole TM-16-126B
- 8.86 g/t Au over 2.5 m in hole TM-16-126BM02
In C2 structure:
- 7.25 g/t Au over 7.5 m in hole TM-16-126BM02
- 21.63 g/t Au over 5.9 m in hole TM-16-146M03
Significant results are also reported in shallower dipping C-Flat structures between the high angle C2 and C3 structures:
- C2-70 - 17.67 g/t Au over 2.1 m in hole TM-16-086
- C2-80 - 17.29 g/t Au over 3.0 m in hole TM-16-126BM02
As illustrated in the longitudinal sections for C1 and C2 (see link below), results from numerous intercepts in these structures are still pending:

Additional C Structure (C7) Identified at depth
Ongoing interpretation of drilling completed since August 2015 has confirmed the presence of an additional sub-parallel, high angle C-Type shear structure located 150m structurally below the C6 zone. The C7 structure remains open in all directions and presently extends from a depth of 975 m to 1,150 m vertical. Results from additional holes drilled below 1,150 m vertical are pending.
Results from this new zone include:
- 8.14 g/t gold over 4.2 m (TM-15-038, previously reported, see full assay table)
- 6.11 g/t gold over 2.4 m (TM-16-146M03, reported in summary table below)

High-Grade Mineralization identified between C-Type Structures
In addition to the mineralization identified in the primary C and C-Flat structures, high grade gold bearing intercepts continue to be identified between the well-defined C structures, demonstrating the possibility for additional mineralized structures to occur. These new mineralized zones represent additional resource upside which will be fully evaluated once underground access is completed.
Uncapped results include the following (all downhole widths, refer to assay table for capped results):
- 37.96 g/t Au over 0.5 m in hole TM-16-086
- 66.95 g/t Au over 0.6 m in hole TM-16-146M03
- 57.94 g/t Au over 0.5 m in hole TM-16-146M03
- 31.47 g/t Au over 1.5 m in hole TM-16-146M03
